Bill is right, and explains it well. I am adding this to what he says. Been running E85 and E100 for 13 years now, building carbs for it, and I build engines designed to run on it specifically. Ethanol is a bit different animal compared to methanol and gasoline. Its sorta in between the other two. With gasoline you need to run the fuel cold, the air cold, the engine cold, because it wants to light off with only heat and pressure, which usually shows up before TDC. The gasoline is easier to light in cold conditions, which is why in the colder months they drop the % to 70 and when its hot out its around 80%-85%, ethanol lights much easier when its hotter, but doesn't want to explode from just heat and pressure, it wants the spark to light it. Without the spark its not a fan of lighting, which is why its such an excellent octane enhancer. It really likes to run in a hot engine, and it doesn't drop much power with the heat, if any at all. Ethanol burns faster than gasoline, but its a softer burn so to speak. Gasoline has a bigger spike in pressure, but ethanol makes more power, a big part of why that happens is due to the oxygen content in the fuel. Ethanol has a lot of O2 in it, and more O2 means more power. Also it has an excellent 'latent heat of vaporization' which means it cools the intake charge as it vaporizes. That makes for a more dense charge in the cylinders, and more power is the result. The boiling point of ethanol be it whiskey, vodka, wine, or fuel is 173F at sea level, it goes up with pressure and down with vacuum like most boiling points do. You can utilize that in an engine to make more power on less fuel, but for the most part adding more ethanol makes more power, up to around 7.5:1 AFR. So running an engine cold like you do on gasoline can cost you power with ethanol. It likes the heat. I run my 11.5:1 Pontiac 455 at 200F-210F on E85 with iron closed chamber heads, its my daily driver all summer and runs mid 11s with a very mild cam and 3.42 gears. You have to mess around with it to find out what your engine combo likes best though. Thats what test and tune is for. Now lifting ring lands is a different thing than flattening the upper rod bearings. Upper rod bearings are flattened by the combustion event spike happening when the piston is on the way up to TDC, it bashes the rod and piston back into the crank journal. When you have strong pistons, but too much compression and timing for pump gas, you get flat bearings in a Pontiac. The sbc is different, they can't take as much ping/knock before they start breaking things like pistons and head gaskets. There are two ways to lift a ring land, one is the gap is too tight and when the rings expand with the heat they have nowhere to go but up, so they break the ring land. The other way is retarded timing with a lean mix on E85. If you are over 10:1 AFR with high cylinder pressures, and you run the timing retarded too far, the fuel can get behind the top ring and when it lights it keeps stressing the lands as the piston goes to BDC. Going lean under boost with any fuel is a really bad idea, and not enough timing is just as bad as too much, though it takes a little longer for it to show up with broken parts. Running on ethanol with too lean a mix is possible NA, but you lose power, drivability, and it doesn't really benefit you. Under boost be it nitrous or turbo/supercharger exacerbates the process and you absolutely need enough fuel in there. Its more than just cylinder pressure, its how much air/fuel is in the chamber and the temperature of everything, so the fast way to breaking an engine is boost and lean. *On gasoline, lean makes more power, but on ethanol rich makes more power,* you want an E85-E100 engine to be on the rich side when its boosted, leaning it out will only break stuff and cost power. Keep throwing fuel at it until it slows down is how I do it for best power. Many of the guys bottle spraying with E85 don't pull any timing, and they don't run the ethanol and race gas mix, because they kinda work against each other and both are hard to light. The turbo guys are all over the place, because the engine design matters a lot and the variables change things more than you might think. Remember, with ethanol you are adding an oxidizer as you add more fuel, it has the O2 in it already. You can run ethanol like you do gasoline, and it is VERY forgiving, but running it like you can and taking advantage of its properties, will get you more power and longevity. Its a different sort of thinking running ethanol. Then you get into methanol like Billy's truck and its all different again. So you know, if you have happened to read this far.. ethanol is the exact same chemical compound, usually made by yeast, that is in whiskey, beer, wine, vodka, etc. I hear there is even some in that White Claw stuff the hipsters drink. Its very simple to make, you take some kind of sugar, mix it with water, add yeast, keep the O2 out of it because otherwise the yeast will bloat themselves and not make ethanol, then you wait a few days to a week for the yeast to do their thing. then you run it through a still because water and ethanol bond to each other in such a way that only the boiling point difference can separate them. A moonshine pot still is kinda meh for proof, the best ones with multiple thumper kegs can get 110-120 proof. Most are around 80 to 90 proof. A packed reflux column or a plate column like utilized in an ethanol plant can get 190-195 proof which means there is 10% to 4% water left over. 100 proof is 50% water, 200 proof is 0% water. there is no sugar or other solids that make it into the fuel, because its all vapor as it passes through the still and solids do not rise in columns very well. You might have guessed I make ethanol fuel too. I make it with maple tree sap and cattail roots. You can drink the fuel coming out of my packed reflux columns, but it doesn't taste good and will suck all the water out of your mouth while burning your throat. Its the worst case of cotton mouth you will get, but man will 190 proof get you drunk quick. To make your own you need a secure location with enough room, and a free permit from BATF for micro-fuel producers, it allows you to make up to 5000 gallons a year, but you have to keep very accurate records and notify the BATF every 3 months as to how much you made. Its a bit of work, and you need somewhere to go with what is left over after fermentation, depending on what you use for starch/sugar. Its usually very good livestock feed, and the farmers with the fattest hogs at the fair were often shiners, and that is one way they found them. Making fuel with corn and other things actually makes more food, because the yeast eat only the parts the animals can't digest easily. the most work is cleaning everything, because if you don't you end up with a really bad smell and other microbes taking up residence and overpowering the yeast. Yeah I got into making fuel and running mycars on it because I wanted to drive my old muscle cars but 87 octane was $5 a gallon 13 years ago. My tree sap vodka costs me about 10 cents a gallon to make it. You really want a bunch of compression to run it, like over 13:1 if you can swing it with an iron head. Otherwise you end up wasting most of the fuel you made, as lower compression ratio engines will make les torque, and end up using more fuel to make less power, that that results in worse mileage. When you are racing, it doesn't really matter how much mileage you get, just throw more fuel at it... unless its gasoline.
The only reason the normal person can't make 190 to 200 is because you would have to take the alcohol vapors and pull them through ceramic beads under a vacuum where the water molecules are larger than the alcohol molecules and can't pass through the beads. You are very right on all the stuff you spoke about I worked in maintenance at an Ethanol plant and learned a lot in the process.
@@philipmazzuca2269 you're welcome. I've been heavily into the ethanol project for years, and I found most of what you hear or read is not quite correct or outright false. Its been lots of testing, driving, and tuning. I soaked Qjets in open buckets of ethanol for a year, then rebuilt them, drilled the passages and daily drove them for several more years. Its a huge subject and there is far more to it than I wrote here. its already long enough as it is so I kept it relatively short. It might be time to start working on videos about it, if there is any interest in the subject. I find ethanol is quite polarizing, most either love it or hate it, and the rest are indifferent. I am not trying to sell anyone anything, I got into it so I could use my 60s era high compression heads on 455s in my daily drivers, and make the fuel myself to save money. I have no dog in the fight, so I have no reason to hand out bad info or disinformation. You can like it or hate it, that is entirely up to you.
@@1qwik4dr you're talking about a molecular sieve, and that is what is required to get the last bit out. I heard about a process using corn cobs to do the same thing, but never read up on it. T o be honest, you don't need to get all the water out to use it as fuel, only to keep ethanol from separating from gasoline while it sits in a tank. Oil and water don't mix, but ethanol mixes easily with both gasoline and water. So you have to get all the water out to keep it from separating. Ethanol is not fond of mixing with most 2 stroke oils though, not sure why. The cool thing is you can mix castor oil or canola/veggie oil with it and run your two strokes on it. Then the only problem is getting air cooled engines up to temp. My chainsaws seem to run good on it, adjust the mix, get just enough canola in it, and they run great. You end up smelling like french fries though. Ethanol is still a viable fuel at 160 proof, but that is where it starts to pull aluminum into suspension via electrolysis. Above 160 proof, its no problem, still makes plenty of power, runs cooler, etc. If you have a 1000 gallon tank, how much water do you have to dump in to get a 4% water content? How much to you have to put in to get 20% water where aluminium 'starts' to be a problem? Now if you have a 20 gallon tank, how much water does it need to make it 80% ethanol and 20% water? 4 gallons is quite a bit of water to dump in the tank. So don't drive in a lake.
I do not believe anyone is going to call you dumb on here, you are more well spoken than most “educated people” on top of that, your racing program proves you know what’s going on and how to figure things out, a true dummy would give up. You sir are a wise old man even tho your just a couple years older than me lol
I love the fact that he tells it like it is. He has patients with the boys. I wish I had a dad like him! He is truly the Hillbilly mad scientist. He is well spoken and appears to be very educated.
Bill there’s not to many things I’ve seen you be wrong about especially if it’s about a carburetor. But you explain it well and your EXACTLY RIGHT!!! So don’t cut yourself short Bill Hoskinson, your a very knowledgeable person 💯
The problem I find is that IF you do not know what the real problem was, then giving a solution is going to be very wrong and WILL create other problems. So going back to the basics ARE a must. Love the way you teach. Even though I am older then you, I can still learn something new LOL.
I dont know why you would say that about you being dumb!The fact that you take the time to give the rest of us some information that could at the least give us an idea about horsepower applications is a God send!Love your channel you and your sons have given me an idea or two I'm now working on! Thank you,God bless and go fast ,ZOOM !!!!
The only thing I’d add is to verify top dead center, just because the timing pointer lines up on you old sbc with the notch in the balancer doesn’t mean it’s at actual tdc. Tdc needs to be verified with a piston stop. Bill you explained this about as good as the teacher I had in automotive college, and he knew his stuff. Keep killing it dude!
I ran into that while trying to time one of my dad's old Harleys. I verified the timing marks probably 20 times and couldn't get it to run right. I finally decided to use a pencil to feel when the piston reached tdc and it wasn't even close to the marks.
I love the Snowman reference from Smokey and the Bandit. I've been watching that movie since i was a kid. Without exaggeration hundreds and hundreds of times. Best movie ever!
If it weren't for TH-cam people would think it was "just a small block chevy with a blow through setup, lol" which is exactly what it is. Love the Channel Bill!
I think you're explaining things just fine, I ain't no Highly Educated individual. So the way your explain it I'm understanding it well, not saying you're not highly educated, but you're doing a very good job teaching.
Thank you sir, I'm really starting to like how you convey yourself and how you teach. Please keep up the great work and information that you're willing to give out.
Wish I had someone like you to teach me these things. I'm working on boosting a sbc. I've got pretty basic knowledge but can't ever know to much. Thank you for these videos. They're more helpful than you think
My dad loves u guys me and him dream of becoming a team like u guys are !! U guys inspired both of us and we are christian folks two we just love the fact u finally started your own channel
Great video and information Bill, thank you! P.S. A "dumb hillbilly ditch digger" you are not! You are too humble, and too hard on yourself, give yourself more credit, you deserve it!
Dang them wheels look good in the back ground. Oh .. ya great info too. I love listening to all that you say. The boys are lucky to have an awsome dad. You have my heart sir. God bless.
Hello, My name is Robert, absolutely love your channel. I’m just like you all self taught, I’ve built and raced lots of cars, boats etc. one of the things that I think would help you guys tremendously is to take and deburr all the sharp edges on your pistons. I’ve raced a lot of supercharged pinch head Chevys on gas, of course we ran the correct race gas for the application. Also I’ve burned my share of pistons to figure this out on my own. Again this is only a suggestion but think it will help you guys a lot. Another thing is to stay away from any spark plugs that have big ground straps they can also cause havoc as well. If the ground strap starts to glow red hot in the combustion chamber that can cause detonation that may be hard to diagnose. Would love to talk to you some time I’m in California. Again keep up the great work, you guys are awesome. Robert
Your a humble man. What you said is right on. The timing number is directly related to efficiency. High quality and high strength parts only give you a tad bit more fudge room. If you ever hear a guy say “it doesn’t matter what brand you buy, I’ve broken all of them”, don’t let him touch your car and talk to somebody else. The guy that’s beating him with stock parts week after week is the one you want to talk to!
Spot on there buddy even as a kid on the streets running raggedy old beaters there's always that one guy who seems to just have the edge and is winning most of the time and he's running nothing a junkyard motor w a. Cam headers and carb he's the one who understood when to make that explosion happen exactly at the perfect time and in high school a dude running a 307 Chevy motor outran about everyone lol gear ratio and curb weight all kinds of factors how cold it was that night so you can cram more air a denser charge into the combustion chamber all that plus many other things play a role
Pops your sons are so lucky to have a dad like you your a good ole countryboy that has a heart of gold, I just wanna say thank you for spreading your knowledge to us, alot of folks like me cant afford the big boy stuff but making something go fast is a hobby, I eat sleep, and dream of one day being able to afford to build a truck on Billy's level,. But I wanna say thank you again for spreading knowledge and helping folks learn cause there is so much missing information out there that causes alot of damage, but I cant wait to meet yal again, have a great night and god bless
3:20 My God what a AWESOME camera shot! Reminds me of cruising in my 69 Elco, I had a tach in that same spot and loved to have the windows down and listen to that SBC hummmmm.....
Love your knowledge I saw you guys run at Milian dragway wanted to come at meet you but you guys were busy . June is a great companion we have a red heeler her name is Ginger she rides with me everyday in my work truck as well and the same on dog crackers very picky lol. I’m currently swapping motors in my old dodge Dakota love trucks hopefully I will get it done by spring but no promises as wife can’t work do to her health so limited funds for the build but you and your sons are awesome I look forward for your videos and you explain things very well and it’s worth a lot to guys like me to learn what you have already done Thank you Thank you Keep it up John
It's nice to see others like myself that see their dogs more as a member of the family rather than a piece of property. I have a couple of pup'pups an I care for each one of them as if their real people if not more.. 🐕🐕
My dog goes everywhere with me too, so I like to see her hope on up into whatever your driving. Love the content and really appreciate these videos where you teach us your knowledge.
You're teaching me a lot more than I used to know you're absolutely right about the timing and the only way to get that right is to pull your heads and turn that crank put it exactly where you needed to be on that down stroke this is stuff I forgot a years ago I've been letting other people do this work for me thank you again
As a father I'm envious in a very good way of the relationship you have with your boys and all that you guys do together. I enjoy your channel just as much as I do your sons, keep up the good work sir!
Thank you for breaking things like this down to us, i dont care how much i have to rewind to soak it all in. Some of us werent raised around cars but have a pretty great intrest in them now. Any and all information is incredibly helpful, especially the way you present it.
I have been following src channel for quite some time now, this new kind of videos from old man are great!! I mean, I am hooked to the channel expecting the next new video to be available... It's like a reality show to call it somehow, keep it coming!!
I'll be waiting on that video, would love to know why! I have one 11:1 cast iron 402ci blown bbc e85 boat motor only likes 34-36 deg depending on air temp. But my na flat top 454 closed chambered cast head pump gas motor wants 38-40 deg and feels like it might like to go higher, but its just a pickup motor in a 1 ton so not necessary to be on the edge. Sure enjoy the content! The ones who know what your talking about, we apriciate the knowledge you are freely passing along.
Another great video sir, I was just having this conversation with a friend the other day, my car is set up on Cam 2 and Cam 2 only, when I try and put pump gas in I have to re adjust timing and carburetor. He swore up and down it made no difference. Im going to forward your video now.
BILL you should do info videos like this one but from the start of building a high hp engine to the end..thank you sir you explain it very well and i'm sure you got some badass old school tricks you could share.
I like the story he tells, is awesome! I hope I knew good English so I can write it better and speak it too. Every time I come from work I watch he's channel, thankyou Mr . Bill.
I'd like to ask u guys and your family to pray for my Dad he was trying to fix our John deer round bailer and he fell off the top of it he is stable now in hospital he is the man who taught me to drag race and built every race care I have driven wrecked etc. He has 5 fractured ribs 4 broken ribs crushed his shoulder and know has double knewmonia please pray for him the guys around the Spa City call him motor Jack so keep him in y'all's prayers god bless and godspeed we believe in u guys keep up the good work plus he just loves watching u guys and especially the old man they have alot in common but dad is a fuel making fool who loves shine if u know what I mean he has blown a few motors in his time and mine also a blower guy we r currently working on a small block blower combo for my luv . I couldn't imagine my life without him in it
This is what most people need advice they can use . Keep giving them good info and hopefully it sinks in . Ditch diggers are smarter then we get credit for that’s a fact .
Your a great teacher. Your material is delivered in a manner that is easily understood by your audience. Reading some of the comments others make in your support lends credence to the information you present. Great presentation and explanation on a topic that is difficult the relay. Thank you for sharing your knowledge with your audience.
Outstanding my friend and like how you explained some of the variables and told people to dig in and research it. Each one of those variables would be video probably. Thanks Sir.
I learned a lot from this video about what timing actually IS. I've learned from and talked with my dad about this plenty of times, but I never pictured the timing of the spark vs. the time it takes to actually light the fuel. I guess I never asked! This was a very good explanation of that.
Not only light the fuel but go thru the rotor to the cap down the wire which lengths change on and into the spark plug thus making this controlled explosion all that has to happen so fast at even 3000 rpms it's mind boggling nevermind 7 or 8 thousand rpms so let that sink in a minute
@@glennmanchester5696 I wonder if this has to do with the longevity and living with higher horsepower on the LS engines vs old gen 1 sbc engines. LS's have a reluctor right on the crank and everything is electronic from there to the coil on plugs, timing is so much more precise vs the old small block that has to travel from the crank through the timing chain and gears, down the cam flexing, through the dizzy gear and up through the shaft before the cap ,rotor and electronics do there job routing the fire out to the plugs. So much movement from flex, slack, harmonics traveling from the crank to the rotor button make ignition tuning on the sbc a mess, that coupled with the fire traveling through the dizzy and wires. We know the oem gen 1 blocks are notorious for being weak but I wonder how much this inferior ignition has to do with it. Most people that spend the money on crank position sensors, flying magnets etc and updated ignition systems for gen 1's, I think in most cases, go with an aftermarket block. I would like to see some high hp test with old stock blocks with some type of crank position reading off the crank, balancer or flywheel coupled with coil on plug and modern electronics and see if those old blocks can live at higher levels. Idk just something that crossed my mind as I read this comment.
that was incredibly informational its hard for me and some others to keep on track some times when people try to explain things but that was on point good job
I gotta healer named rowdy. I think he's 12 now. He still rides and knows where every place he gets treats at. Whether it be the bank drive thru or a store. He's been a dear friend.
WoW and wow again thank u Thump Er thats a whole lot of great info i for one would read or watch ur vids look forward to it and ole bill keepem comin champ!!!!
Yeah I can say two years ago I didn’t know shit!! I thought I did until I picked up tuning instead of just turning a wrench. Which I can say that I love doing I can’t get enough of it . But it’s definitely a different word. I think this was a great discussion that younger people need to hear cause I see it a lot going in and fixing different tunes. And I’ll give everyone a little if my own advise alway run a Wideband gauge you should never leave home with out it . Thanks Old man God Bless.
You are a smart hillbilly. Im only a couple yrs younger. You remind me of my grandpa and dad, smart about a little bit of everything and love drag racing. I had a English bulldog but had to put it down at 10 yrs old, and now I got a boxer who is the same way. They want the biscuit but they don't want to eat it, it halves to be human food. They are/were like her, they would go everywhere I went and I would take them. Just awesome! I went through a couple custom set of diamond pistons on my first go round with a bbc e85 before I said wait, I can't keep this up, then Scottie Duggins start working with me and doing my engines for me, but I do rebuilds and maintenance. I can't agree with you more on the internet deal and your also spot on about the fuel and sbc with timing and all that. Are you guys gonna be running one of Kevin's blow through e85 dual needle and seat carbs like on Jr's truck? If don't know, I was APD e85 but I went with a bad ass new black all billet IRD dual needle and seat blow through carb, 540 f3-136 BBC. Damn good carb!
You vids are awesome.And that 55 is top notch.I don’t know if you have ever heard of The Surfers from 1966.They ran a top fueler on a shoestring budget.But they studied the chemical make up of nitro methane.As a result they were able to run up to 98% nitro without breaking parts.Anyways,this reminds me of how you guys approach drag racing.You analyze and learn from broken parts.If you get a chance look up The Surfers on Google.There’s a good article about them and some TH-cam vids about them.Take care👍
First off.. Thank you sir... I for one can say that I love the technical info and personal thoughts.. A part of me relates to you and your family so much.. my pops ran circle track dirt cars my whole life... I spent alot of time out in the garage as a child too and I love the down home "good ol boy's" attitude that you give off... Id love to spend some time with you and learn some of the engine game that i failed to pick up before it was too late....... I know you hate em' but I have a turbo ls colorado that I built everthing on completely from scratch... Its not bad hahaa.. Keep doing what you do sir... We will keep 👀.... Hahahha Thanks again!!
Probably like your dad, I tried to keep my old 327 running at it's best too long, because when the fuel changed, it was the beginning of the end. For those old motors from that era, because new fuels really weren't kind to our old technology. We could make them run strong, but we were beating the life out of them almost as fast as they would run. Which took a little time to show the destruction of what unleaded gas was doing to our once perfect setups, that loved the 165 to 180 degree temperature thermostats. Only the fuel of the day required 210 to 220 degrees in the blocks, and harder valves, and other harden components to withstand the lack of lead additive we grew up on. Whole new learning curve went through the hot rodding mainstream, as we learned to get around this new fuel the government dropped into our lifestyle. This shortly after the price had jumped to unheard of prices, and hard to find even regular gas, after sitting for who knows how long just to get a few gallons of that. Ethoal was gone, and we were forced to by octane boosters, at the least, and find lead additives in a can if you could, all of which was hard on newly weds, because it tripled the cost of a gallon of overpriced unleaded gas. We thought the late 70's sucked as far as nice fast cars went, because they up and all but left the planet, and the early 80's was a kick in the guts, but lower, as far as going fast from showroom went. We slowly learned to make power that last, but the price tags jumped up three times the cost, from few years earlier. If you either spent way more than young married couple with couple young kids could afford, had a wife that was bitten as bad as you, made above average pay, single living at home, divorced ," another subject!", sponsored, are you parked your old hot rods, and slowly watched them fade into nothing, with the hopes that one day. But 4 bangers, v6's, and denutted V8's were all there was, until Japan hit with the turbos, and GM dropped the Buick 3.8 V6 on the market, and Ford, had gotten the nuts to raise the stakes with the GT's with Cobra supercharger package, and the SC Cougars, and SC Tbirds V6's. That's about time some of us started to learned what your talking about, to put it into everyday hot rodders skill set, unless you were a part of a race team, it was all new to average kid trying to go fast in your 140 hp factory POS cars. Only most didn't learn the whole picture, because the ECU, and forced induction took place of most kids learning learning curves. With limited ones really getting a grip on the real facts of going fast from home built until late 90's, is the way I seen it. With the corn factor added in 2006, but even that took a couple years to show its power to the few progressive people. Thus your age group got its act together somewhat, but I don't see many sharing the knowledge as we once did, your the exception to the rule. Yeah they sell you the parts, and some nerds learned to work the ECU's, but only the few mastered the art of home built all motor real power, but by then it is all forced induction, are NOS systems with different chips to plug into ignition boxes, and are jets to put on the NOS systems, and instructions of what one to plug in for different amounts, with no explanation of why. Now you have intercoolers, NOS to spool the turbos up faster, and crate motors set up to take one are all the above, and someone else doing the thinking for most of them. So it's all Greek to most kids, people what your talking about. I believe that is the typical breakdown of the evolution of where we're at basically right now, with the exception of limited numbers, everyone else relays on the tuner shops to do the thinking for the most part.
Bill all that info was great. I’ve been playing with timing in our 468 Bbc. It’s in a 69’ Nova we race in memory of the young man who purchased it at 17 due to his love of the sport. That’s a whole other story I’d love to share one day. Back to your statement of ensuring ignition at 10 degrees past tdc. I’m still learning a lot and slowly figuring it out. This might sound stupid but I’m asking because I don’t know. We rebuilt our N/A combo this year with a hydraulic roller cam, hydraulic lifters, roller rockers etc. We Learned the hard way about running cheap push rods when we broke four and then ran the rest of the season with better Manely push rods, but I think when we broke the push rods we actually damaged a trunion on the number one exhaust valve. Found it pointing toward the valley at Summit regional finals race at Ennis, Tx on a test pass. It ended our season. Haven’t dug into it yet but wanting to ensure the timing I have set is working correctly. Currently set at 35 degrees. Thanks again for the info. Just searching knowledge as I always do
He wasn't saying you are ensuring anything at 10* atdc. He was generalizing. It's not a given number to determine optimal timing. Every engine is different, and will require different timing settings. Too many factors involved. But if i can help, from what i have seen on the engine dyno and the track, a good baseline for what you have is 36* total timing. Finding the optimal sweet spot for YOUR combination, which may be a little more or a little less, will require extensive tuning, either at the track, or on a dyno. Hope this helps.
@@vengeanceizmine9878 absolutely and I appreciate the info. We did start out at 36 and while testing different theories and settings I found 35 to be where we picked up mph. Wasn’t able to adjust anymore from there just due to other issues having to be dealt with. My ears are always open to anyone who’s willing to give advice. Ty very much VengeanceIzMine! I appreciate it.

Bill is right, and explains it well. I am adding this to what he says.
Been running E85 and E100 for 13 years now, building carbs for it, and I build engines designed to run on it specifically. Ethanol is a bit different animal compared to methanol and gasoline. Its sorta in between the other two. With gasoline you need to run the fuel cold, the air cold, the engine cold, because it wants to light off with only heat and pressure, which usually shows up before TDC. The gasoline is easier to light in cold conditions, which is why in the colder months they drop the % to 70 and when its hot out its around 80%-85%, ethanol lights much easier when its hotter, but doesn't want to explode from just heat and pressure, it wants the spark to light it. Without the spark its not a fan of lighting, which is why its such an excellent octane enhancer. It really likes to run in a hot engine, and it doesn't drop much power with the heat, if any at all.
Ethanol burns faster than gasoline, but its a softer burn so to speak. Gasoline has a bigger spike in pressure, but ethanol makes more power, a big part of why that happens is due to the oxygen content in the fuel. Ethanol has a lot of O2 in it, and more O2 means more power. Also it has an excellent 'latent heat of vaporization' which means it cools the intake charge as it vaporizes. That makes for a more dense charge in the cylinders, and more power is the result. The boiling point of ethanol be it whiskey, vodka, wine, or fuel is 173F at sea level, it goes up with pressure and down with vacuum like most boiling points do. You can utilize that in an engine to make more power on less fuel, but for the most part adding more ethanol makes more power, up to around 7.5:1 AFR. So running an engine cold like you do on gasoline can cost you power with ethanol. It likes the heat. I run my 11.5:1 Pontiac 455 at 200F-210F on E85 with iron closed chamber heads, its my daily driver all summer and runs mid 11s with a very mild cam and 3.42 gears. You have to mess around with it to find out what your engine combo likes best though. Thats what test and tune is for.
Now lifting ring lands is a different thing than flattening the upper rod bearings. Upper rod bearings are flattened by the combustion event spike happening when the piston is on the way up to TDC, it bashes the rod and piston back into the crank journal. When you have strong pistons, but too much compression and timing for pump gas, you get flat bearings in a Pontiac. The sbc is different, they can't take as much ping/knock before they start breaking things like pistons and head gaskets.
There are two ways to lift a ring land, one is the gap is too tight and when the rings expand with the heat they have nowhere to go but up, so they break the ring land. The other way is retarded timing with a lean mix on E85. If you are over 10:1 AFR with high cylinder pressures, and you run the timing retarded too far, the fuel can get behind the top ring and when it lights it keeps stressing the lands as the piston goes to BDC. Going lean under boost with any fuel is a really bad idea, and not enough timing is just as bad as too much, though it takes a little longer for it to show up with broken parts.
Running on ethanol with too lean a mix is possible NA, but you lose power, drivability, and it doesn't really benefit you. Under boost be it nitrous or turbo/supercharger exacerbates the process and you absolutely need enough fuel in there. Its more than just cylinder pressure, its how much air/fuel is in the chamber and the temperature of everything, so the fast way to breaking an engine is boost and lean. *On gasoline, lean makes more power, but on ethanol rich makes more power,* you want an E85-E100 engine to be on the rich side when its boosted, leaning it out will only break stuff and cost power. Keep throwing fuel at it until it slows down is how I do it for best power.
Many of the guys bottle spraying with E85 don't pull any timing, and they don't run the ethanol and race gas mix, because they kinda work against each other and both are hard to light. The turbo guys are all over the place, because the engine design matters a lot and the variables change things more than you might think. Remember, with ethanol you are adding an oxidizer as you add more fuel, it has the O2 in it already. You can run ethanol like you do gasoline, and it is VERY forgiving, but running it like you can and taking advantage of its properties, will get you more power and longevity. Its a different sort of thinking running ethanol.
Then you get into methanol like Billy's truck and its all different again.
So you know, if you have happened to read this far.. ethanol is the exact same chemical compound, usually made by yeast, that is in whiskey, beer, wine, vodka, etc. I hear there is even some in that White Claw stuff the hipsters drink. Its very simple to make, you take some kind of sugar, mix it with water, add yeast, keep the O2 out of it because otherwise the yeast will bloat themselves and not make ethanol, then you wait a few days to a week for the yeast to do their thing. then you run it through a still because water and ethanol bond to each other in such a way that only the boiling point difference can separate them.
A moonshine pot still is kinda meh for proof, the best ones with multiple thumper kegs can get 110-120 proof. Most are around 80 to 90 proof. A packed reflux column or a plate column like utilized in an ethanol plant can get 190-195 proof which means there is 10% to 4% water left over. 100 proof is 50% water, 200 proof is 0% water. there is no sugar or other solids that make it into the fuel, because its all vapor as it passes through the still and solids do not rise in columns very well.
You might have guessed I make ethanol fuel too. I make it with maple tree sap and cattail roots. You can drink the fuel coming out of my packed reflux columns, but it doesn't taste good and will suck all the water out of your mouth while burning your throat. Its the worst case of cotton mouth you will get, but man will 190 proof get you drunk quick. To make your own you need a secure location with enough room, and a free permit from BATF for micro-fuel producers, it allows you to make up to 5000 gallons a year, but you have to keep very accurate records and notify the BATF every 3 months as to how much you made. Its a bit of work, and you need somewhere to go with what is left over after fermentation, depending on what you use for starch/sugar. Its usually very good livestock feed, and the farmers with the fattest hogs at the fair were often shiners, and that is one way they found them. Making fuel with corn and other things actually makes more food, because the yeast eat only the parts the animals can't digest easily.
the most work is cleaning everything, because if you don't you end up with a really bad smell and other microbes taking up residence and overpowering the yeast.
Yeah I got into making fuel and running mycars on it because I wanted to drive my old muscle cars but 87 octane was $5 a gallon 13 years ago. My tree sap vodka costs me about 10 cents a gallon to make it. You really want a bunch of compression to run it, like over 13:1 if you can swing it with an iron head. Otherwise you end up wasting most of the fuel you made, as lower compression ratio engines will make les torque, and end up using more fuel to make less power, that that results in worse mileage. When you are racing, it doesn't really matter how much mileage you get, just throw more fuel at it... unless its gasoline.
Guys.. I am honored you pinned this.
Outstanding thanks
The only reason the normal person can't make 190 to 200 is because you would have to take the alcohol vapors and pull them through ceramic beads under a vacuum where the water molecules are larger than the alcohol molecules and can't pass through the beads. You are very right on all the stuff you spoke about I worked in maintenance at an Ethanol plant and learned a lot in the process.
@@philipmazzuca2269 you're welcome. I've been heavily into the ethanol project for years, and I found most of what you hear or read is not quite correct or outright false. Its been lots of testing, driving, and tuning. I soaked Qjets in open buckets of ethanol for a year, then rebuilt them, drilled the passages and daily drove them for several more years.
Its a huge subject and there is far more to it than I wrote here. its already long enough as it is so I kept it relatively short.
It might be time to start working on videos about it, if there is any interest in the subject. I find ethanol is quite polarizing, most either love it or hate it, and the rest are indifferent.
I am not trying to sell anyone anything, I got into it so I could use my 60s era high compression heads on 455s in my daily drivers, and make the fuel myself to save money. I have no dog in the fight, so I have no reason to hand out bad info or disinformation. You can like it or hate it, that is entirely up to you.
@@1qwik4dr you're talking about a molecular sieve, and that is what is required to get the last bit out. I heard about a process using corn cobs to do the same thing, but never read up on it. T
o be honest, you don't need to get all the water out to use it as fuel, only to keep ethanol from separating from gasoline while it sits in a tank. Oil and water don't mix, but ethanol mixes easily with both gasoline and water. So you have to get all the water out to keep it from separating.
Ethanol is not fond of mixing with most 2 stroke oils though, not sure why. The cool thing is you can mix castor oil or canola/veggie oil with it and run your two strokes on it. Then the only problem is getting air cooled engines up to temp. My chainsaws seem to run good on it, adjust the mix, get just enough canola in it, and they run great. You end up smelling like french fries though.
Ethanol is still a viable fuel at 160 proof, but that is where it starts to pull aluminum into suspension via electrolysis. Above 160 proof, its no problem, still makes plenty of power, runs cooler, etc.
If you have a 1000 gallon tank, how much water do you have to dump in to get a 4% water content? How much to you have to put in to get 20% water where aluminium 'starts' to be a problem? Now if you have a 20 gallon tank, how much water does it need to make it 80% ethanol and 20% water? 4 gallons is quite a bit of water to dump in the tank. So don't drive in a lake.
A man with this much knowledge, who’s willing to help anyone, is a priceless commodity to the racing world. Thank you Bill.
Big Scott from
New York
I do not believe anyone is going to call you dumb on here, you are more well spoken than most “educated people” on top of that, your racing program proves you know what’s going on and how to figure things out, a true dummy would give up. You sir are a wise old man even tho your just a couple years older than me lol
I love the fact that he tells it like it is. He has patients with the boys. I wish I had a dad like him! He is truly the Hillbilly mad scientist. He is well spoken and appears to be very educated.
She’s looking at you “like dad come on we gotta get rid of this bad treat and get the good ones” 🤣😂
Big Ennis Burdett. Bur... Ber...Hell I got to go!
Oh man you beat me to it! LoL well done.👍 I was going to say the exact same thing.
Loved the Smokey and the Bandit reference with your brother haha. Most young people won't catch that. Classic.
June wants the chicken fries!!! Too good of a pup for dog biscuits. Lol
Bill there’s not to many things I’ve seen you be wrong about especially if it’s about a carburetor. But you explain it well and your EXACTLY RIGHT!!! So don’t cut yourself short Bill Hoskinson, your a very knowledgeable person 💯
Your not dumb sir and actually you r spot on with how you explained ignition timing w/ boost very accurately.good job.
The problem I find is that IF you do not know what the real problem was, then giving a solution is going to be very wrong and WILL create other problems. So going back to the basics ARE a must. Love the way you teach. Even though I am older then you, I can still learn something new LOL.
I dont know why you would say that about you being dumb!The fact that you take the time to give the rest of us some information that could at the least give us an idea about horsepower applications is a God send!Love your channel you and your sons have given me an idea or two I'm now working on! Thank you,God bless and go fast ,ZOOM !!!!
The only thing I’d add is to verify top dead center, just because the timing pointer lines up on you old sbc with the notch in the balancer doesn’t mean it’s at actual tdc. Tdc needs to be verified with a piston stop. Bill you explained this about as good as the teacher I had in automotive college, and he knew his stuff. Keep killing it dude!
I ran into that while trying to time one of my dad's old Harleys. I verified the timing marks probably 20 times and couldn't get it to run right. I finally decided to use a pencil to feel when the piston reached tdc and it wasn't even close to the marks.
Had a few heelers growing up and they are definitely one of the smartest breeds out there, and I love them with their tails even better
Bill, you are are a wealth of knowledge. Don't kid yourself!
Truly one of the best TH-cam channel thank you so much for your wisdom god bless
I love the Snowman reference from Smokey and the Bandit. I've been watching that movie since i was a kid. Without exaggeration hundreds and hundreds of times. Best movie ever!
If it weren't for TH-cam people would think it was "just a small block chevy with a blow through setup, lol" which is exactly what it is. Love the Channel Bill!
Picking up parts for your dump truck with your dog in a badass 55. Fucking awesome. And your are not dumb, explained it perfect!!!!
I think you're explaining things just fine, I ain't no Highly Educated individual. So the way your explain it I'm understanding it well, not saying you're not highly educated, but you're doing a very good job teaching.
Thank you sir, I'm really starting to like how you convey yourself and how you teach. Please keep up the great work and information that you're willing to give out.
Wish I had someone like you to teach me these things. I'm working on boosting a sbc. I've got pretty basic knowledge but can't ever know to much. Thank you for these videos. They're more helpful than you think
Loving this channel, no bullshit, no secret squirrel business just straight up real world experience and explanations.
My dad loves u guys me and him dream of becoming a team like u guys are !! U guys inspired both of us and we are christian folks two we just love the fact u finally started your own channel
Great video and information Bill, thank you!
P.S. A "dumb hillbilly ditch digger" you are not!
You are too humble, and too hard on yourself, give yourself more credit, you deserve it!
Dang them wheels look good in the back ground. Oh .. ya great info too. I love listening to all that you say. The boys are lucky to have an awsome dad. You have my heart sir. God bless.
Hello,
My name is Robert, absolutely love your channel. I’m just like you all self taught, I’ve built and raced lots of cars, boats etc. one of the things that I think would help you guys tremendously is to take and deburr all the sharp edges on your pistons. I’ve raced a lot of supercharged pinch head Chevys on gas, of course we ran the correct race gas for the application. Also I’ve burned my share of pistons to figure this out on my own. Again this is only a suggestion but think it will help you guys a lot. Another thing is to stay away from any spark plugs that have big ground straps they can also cause havoc as well. If the ground strap starts to glow red hot in the combustion chamber that can cause detonation that may be hard to diagnose. Would love to talk to you some time I’m in California. Again keep up the great work, you guys are awesome.
Robert
Thanks for sharing your knowledge! My favorite channel hands down.
Your a humble man. What you said is right on. The timing number is directly related to efficiency. High quality and high strength parts only give you a tad bit more fudge room. If you ever hear a guy say “it doesn’t matter what brand you buy, I’ve broken all of them”, don’t let him touch your car and talk to somebody else. The guy that’s beating him with stock parts week after week is the one you want to talk to!
Spot on there buddy even as a kid on the streets running raggedy old beaters there's always that one guy who seems to just have the edge and is winning most of the time and he's running nothing a junkyard motor w a. Cam headers and carb he's the one who understood when to make that explosion happen exactly at the perfect time and in high school a dude running a 307 Chevy motor outran about everyone lol gear ratio and curb weight all kinds of factors how cold it was that night so you can cram more air a denser charge into the combustion chamber all that plus many other things play a role
I love when you drop performance knowledge! This is going to be a lot of fun learning from you!! Thank you sir.
Pops your sons are so lucky to have a dad like you your a good ole countryboy that has a heart of gold, I just wanna say thank you for spreading your knowledge to us, alot of folks like me cant afford the big boy stuff but making something go fast is a hobby, I eat sleep, and dream of one day being able to afford to build a truck on Billy's level,. But I wanna say thank you again for spreading knowledge and helping folks learn cause there is so much missing information out there that causes alot of damage, but I cant wait to meet yal again, have a great night and god bless
Saw Billy on Street Outlaws race night in America. "Maverick" 👍
Oh yeah and that other time when his name was "Brad" lol
best explanation ever !! wish I knew this 20 yrs ago.. awesome work on keeping the sport alive
3:20 My God what a AWESOME camera shot! Reminds me of cruising in my 69 Elco, I had a tach in that same spot and loved to have the windows down and listen to that SBC hummmmm.....
I thought I understood ignition timing until I watched this video. Always learning something new from the old man
June makes your show, I love watching her
Love your knowledge I saw you guys run at Milian dragway wanted to come at meet you but you guys were busy . June is a great companion we have a red heeler her name is Ginger she rides with me everyday in my work truck as well and the same on dog crackers very picky lol. I’m currently swapping motors in my old dodge Dakota love trucks hopefully I will get it done by spring but no promises as wife can’t work do to her health so limited funds for the build but you and your sons are awesome I look forward for your videos and you explain things very well and it’s worth a lot to guys like me to learn what you have already done
Thank you Thank you
Keep it up
John
Between you and Uncle Tony I have leaned more in the last 6 months then in the last 6 years. Thank You
It's nice to see others like myself that see their dogs more as a member of the family rather than a piece of property. I have a couple of pup'pups an I care for each one of them as if their real people if not more.. 🐕🐕
My dog goes everywhere with me too, so I like to see her hope on up into whatever your driving. Love the content and really appreciate these videos where you teach us your knowledge.
Sir i think ur very smart and u help ppl with there cars . This is best channel on youtube
You're teaching me a lot more than I used to know you're absolutely right about the timing and the only way to get that right is to pull your heads and turn that crank put it exactly where you needed to be on that down stroke this is stuff I forgot a years ago I've been letting other people do this work for me thank you again
As a father I'm envious in a very good way of the relationship you have with your boys and all that you guys do together. I enjoy your channel just as much as I do your sons, keep up the good work sir!
Pops with back 2 back videos 💯 much love from Dallas Texas 💯🤟🏼🇲🇽
Thank you for breaking things like this down to us, i dont care how much i have to rewind to soak it all in. Some of us werent raised around cars but have a pretty great intrest in them now. Any and all information is incredibly helpful, especially the way you present it.
Awesome explanation of ignition timing👍
I have been following src channel for quite some time now, this new kind of videos from old man are great!! I mean, I am hooked to the channel expecting the next new video to be available... It's like a reality show to call it somehow, keep it coming!!
I'll be waiting on that video, would love to know why! I have one 11:1 cast iron 402ci blown bbc e85 boat motor only likes 34-36 deg depending on air temp. But my na flat top 454 closed chambered cast head pump gas motor wants 38-40 deg and feels like it might like to go higher, but its just a pickup motor in a 1 ton so not necessary to be on the edge. Sure enjoy the content! The ones who know what your talking about, we apriciate the knowledge you are freely passing along.
Did not understand what you were talking about until you use the whack a mole analogy. Now I understand.
You really are an excellent teacher. You have great examples and explain things very well.
You don't know how much this helped me out thank sir
Have a heeler that is picky just like that hahaha! You and your kids are great and I really like all your videos when I have time to watch them
June is great. Lol I have an uncle who used to take a bite out of every treat he fed his dog.
Another great video sir, I was just having this conversation with a friend the other day, my car is set up on Cam 2 and Cam 2 only, when I try and put pump gas in I have to re adjust timing and carburetor. He swore up and down it made no difference. Im going to forward your video now.
Great info man. Tuning is an art. What works on one engine may not work on your engine. It's a complete system of parts and events.
Pop's I'm lost for words you don't give yourself enough credit your very smart
I enjoyed the tech video! The more old man knowledge u can give the better we will all be! More tech vids a must!
June is so sweet, I don't know what I'd do without my pup CUDA. She's my service dog and thinks she's human just like June.
Thank you sr...your videos are always helpful...im just starting to build a turbo sbf...your video gave me alot more to think about
We want our own June Dog! 💕
We think you are very knowledgeable and informative....keep on keepin on!
BILL you should do info videos like this one but from the start of building a high hp engine to the end..thank you sir you explain it very well and i'm sure you got some badass old school tricks you could share.
Great show lots of great information Waco Willis Texas
You would be an excellent teacher!!
Any person that can learn from there own and others mistakes is not dumb. You are a well educated man Bill. It's called the school of hard knocks.
Your a good pops.. wished I had a dad that was involved in my motor sports like you. Keep up tha great content!
Love tha other channel!
I like the story he tells, is awesome!
I hope I knew good English so I can write it better and speak it too.
Every time I come from work I watch he's channel, thankyou Mr . Bill.
I'd like to ask u guys and your family to pray for my Dad he was trying to fix our John deer round bailer and he fell off the top of it he is stable now in hospital he is the man who taught me to drag race and built every race care I have driven wrecked etc. He has 5 fractured ribs 4 broken ribs crushed his shoulder and know has double knewmonia please pray for him the guys around the Spa City call him motor Jack so keep him in y'all's prayers god bless and godspeed we believe in u guys keep up the good work plus he just loves watching u guys and especially the old man they have alot in common but dad is a fuel making fool who loves shine if u know what I mean he has blown a few motors in his time and mine also a blower guy we r currently working on a small block blower combo for my luv . I couldn't imagine my life without him in it
Just prayed for him, hoping he makes a full and fast recovery. Hang in there! 🙏🏻
This is what most people need advice they can use . Keep giving them good info and hopefully it sinks in . Ditch diggers are smarter then we get credit for that’s a fact .
Your a great teacher. Your material is delivered in a manner that is easily understood by your audience. Reading some of the comments others make in your support lends credence to the information you present. Great presentation and explanation on a topic that is difficult the relay. Thank you for sharing your knowledge with your audience.
Outstanding my friend and like how you explained some of the variables and told people to dig in and research it. Each one of those variables would be video probably. Thanks Sir.
By far one of the best channels out there. 👍
Truly awesome channel. I love all the tips on everything love the dogs too keep putting the videos out and i will keep liking and watching
I learned a lot from this video about what timing actually IS. I've learned from and talked with my dad about this plenty of times, but I never pictured the timing of the spark vs. the time it takes to actually light the fuel. I guess I never asked! This was a very good explanation of that.
Not only light the fuel but go thru the rotor to the cap down the wire which lengths change on and into the spark plug thus making this controlled explosion all that has to happen so fast at even 3000 rpms it's mind boggling nevermind 7 or 8 thousand rpms so let that sink in a minute
@@glennmanchester5696 I wonder if this has to do with the longevity and living with higher horsepower on the LS engines vs old gen 1 sbc engines. LS's have a reluctor right on the crank and everything is electronic from there to the coil on plugs, timing is so much more precise vs the old small block that has to travel from the crank through the timing chain and gears, down the cam flexing, through the dizzy gear and up through the shaft before the cap ,rotor and electronics do there job routing the fire out to the plugs. So much movement from flex, slack, harmonics traveling from the crank to the rotor button make ignition tuning on the sbc a mess, that coupled with the fire traveling through the dizzy and wires. We know the oem gen 1 blocks are notorious for being weak but I wonder how much this inferior ignition has to do with it. Most people that spend the money on crank position sensors, flying magnets etc and updated ignition systems for gen 1's, I think in most cases, go with an aftermarket block. I would like to see some high hp test with old stock blocks with some type of crank position reading off the crank, balancer or flywheel coupled with coil on plug and modern electronics and see if those old blocks can live at higher levels. Idk just something that crossed my mind as I read this comment.
that was incredibly informational its hard for me and some others to keep on track some times when people try to explain things but that was on point good job
I gotta healer named rowdy. I think he's 12 now. He still rides and knows where every place he gets treats at. Whether it be the bank drive thru or a store. He's been a dear friend.
Very informative. I spoke to Jason about fuel the other day. Told him I saw the fuel on your channel
He’s such a fantastic person. Huge help
Any advice is good advice in my book. Your boys trucks are crazy fast. Love the videos.
WoW and wow again thank u Thump Er thats a whole lot of great info i for one would read or watch ur vids look forward to it and ole bill keepem comin champ!!!!
Those heelers are great dogs they are so smart
Great info mate... thanks for sharing your knowledge
Yeah I can say two years ago I didn’t know shit!! I thought I did until I picked up tuning instead of just turning a wrench. Which I can say that I love doing I can’t get enough of it . But it’s definitely a different word. I think this was a great discussion that younger people need to hear cause I see it a lot going in and fixing different tunes. And I’ll give everyone a little if my own advise alway run a Wideband gauge you should never leave home with out it . Thanks Old man God Bless.
As a graduate of school of auto machinist I like what you are doing with these tech videos for new comers something I wish I thought of. Keep it up. 👍
I have taken a few of young SAM students along with Wyo techs under my wing and I am always impressed with SAM students.
The wyo techs not so much.
Hiya Bill ,Great video great entertainment, learnt a lot thanks for sharing
Thanks again. This really helps me understand some things I never thought about and honestly was never tought.alot of this I just took for granted....
You are a smart hillbilly. Im only a couple yrs younger. You remind me of my grandpa and dad, smart about a little bit of everything and love drag racing. I had a English bulldog but had to put it down at 10 yrs old, and now I got a boxer who is the same way. They want the biscuit but they don't want to eat it, it halves to be human food. They are/were like her, they would go everywhere I went and I would take them.
Just awesome! I went through a couple custom set of diamond pistons on my first go round with a bbc e85 before I said wait, I can't keep this up, then Scottie Duggins start working with me and doing my engines for me, but I do rebuilds and maintenance.
I can't agree with you more on the internet deal and your also spot on about the fuel and sbc with timing and all that. Are you guys gonna be running one of Kevin's blow through e85 dual needle and seat carbs like on Jr's truck? If don't know, I was APD e85 but I went with a bad ass new black all billet IRD dual needle and seat blow through carb, 540 f3-136 BBC. Damn good carb!
Now I’m really itching to build up my ls chevy. I’m really learning good info. Thank you.
Definitely becoming my favorite channel
Man these videos are something I never knew I needed keep up the good work
Awesome of you to take time and try help a guy out
If yall are ever near Nashville tn and need a shop or anything else just hollar love the vids
Great info again, hate seeing the videos end.. Thanks for the info.
My new favorite car channel I would love to spend a day with y’all at the track
Exactly. If you pull 2-3* out of the setup and it doesn't go slower, consider yourself lucky it didn't scatter itself in the pan.
You vids are awesome.And that 55 is top notch.I don’t know if you have ever heard of The Surfers from 1966.They ran a top fueler on a shoestring budget.But they studied the chemical make up of nitro methane.As a result they were able to run up to 98% nitro without breaking parts.Anyways,this reminds me of how you guys approach drag racing.You analyze and learn from broken parts.If you get a chance look up The Surfers on Google.There’s a good article about them and some TH-cam vids about them.Take care👍
Keep up the great content old man! You are helping more gear heads then you know!
First off.. Thank you sir... I for one can say that I love the technical info and personal thoughts.. A part of me relates to you and your family so much.. my pops ran circle track dirt cars my whole life... I spent alot of time out in the garage as a child too and I love the down home "good ol boy's" attitude that you give off... Id love to spend some time with you and learn some of the engine game that i failed to pick up before it was too late....... I know you hate em' but I have a turbo ls colorado that I built everthing on completely from scratch... Its not bad hahaa.. Keep doing what you do sir... We will keep 👀.... Hahahha Thanks again!!
Probably like your dad, I tried to keep my old 327 running at it's best too long, because when the fuel changed, it was the beginning of the end. For those old motors from that era, because new fuels really weren't kind to our old technology.
We could make them run strong, but we were beating the life out of them almost as fast as they would run. Which took a little time to show the destruction of what unleaded gas was doing to our once perfect setups, that loved the 165 to 180 degree temperature thermostats.
Only the fuel of the day required 210 to 220 degrees in the blocks, and harder valves, and other harden components to withstand the lack of lead additive we grew up on.
Whole new learning curve went through the hot rodding mainstream, as we learned to get around this new fuel the government dropped into our lifestyle. This shortly after the price had jumped to unheard of prices, and hard to find even regular gas, after sitting for who knows how long just to get a few gallons of that.
Ethoal was gone, and we were forced to by octane boosters, at the least, and find lead additives in a can if you could, all of which was hard on newly weds, because it tripled the cost of a gallon of overpriced unleaded gas.
We thought the late 70's sucked as far as nice fast cars went, because they up and all but left the planet, and the early 80's was a kick in the guts, but lower, as far as going fast from showroom went.
We slowly learned to make power that last, but the price tags jumped up three times the cost, from few years earlier. If you either spent way more than young married couple with couple young kids could afford, had a wife that was bitten as bad as you, made above average pay, single living at home, divorced ," another subject!", sponsored, are you parked your old hot rods, and slowly watched them fade into nothing, with the hopes that one day.
But 4 bangers, v6's, and denutted V8's were all there was, until Japan hit with the turbos, and GM dropped the Buick 3.8 V6 on the market, and Ford, had gotten the nuts to raise the stakes with the GT's with Cobra supercharger package, and the SC Cougars, and SC Tbirds V6's.
That's about time some of us started to learned what your talking about, to put it into everyday hot rodders skill set, unless you were a part of a race team, it was all new to average kid trying to go fast in your 140 hp factory POS cars.
Only most didn't learn the whole picture, because the ECU, and forced induction took place of most kids learning learning curves. With limited ones really getting a grip on the real facts of going fast from home built until late 90's, is the way I seen it.
With the corn factor added in 2006, but even that took a couple years to show its power to the few progressive people. Thus your age group got its act together somewhat, but I don't see many sharing the knowledge as we once did, your the exception to the rule.
Yeah they sell you the parts, and some nerds learned to work the ECU's, but only the few mastered the art of home built all motor real power, but by then it is all forced induction, are NOS systems with different chips to plug into ignition boxes, and are jets to put on the NOS systems, and instructions of what one to plug in for different amounts, with no explanation of why.
Now you have intercoolers, NOS to spool the turbos up faster, and crate motors set up to take one are all the above, and someone else doing the thinking for most of them. So it's all Greek to most kids, people what your talking about.
I believe that is the typical breakdown of the evolution of where we're at basically right now, with the exception of limited numbers, everyone else relays on the tuner shops to do the thinking for the most part.
Bill all that info was great. I’ve been playing with timing in our 468 Bbc. It’s in a 69’ Nova we race in memory of the young man who purchased it at 17 due to his love of the sport. That’s a whole other story I’d love to share one day. Back to your statement of ensuring ignition at 10 degrees past tdc. I’m still learning a lot and slowly figuring it out. This might sound stupid but I’m asking because I don’t know. We rebuilt our N/A combo this year with a hydraulic roller cam, hydraulic lifters, roller rockers etc. We Learned the hard way about running cheap push rods when we broke four and then ran the rest of the season with better Manely push rods, but I think when we broke the push rods we actually damaged a trunion on the number one exhaust valve. Found it pointing toward the valley at Summit regional finals race at Ennis, Tx on a test pass. It ended our season. Haven’t dug into it yet but wanting to ensure the timing I have set is working correctly. Currently set at 35 degrees. Thanks again for the info. Just searching knowledge as I always do
He wasn't saying you are ensuring anything at 10* atdc. He was generalizing. It's not a given number to determine optimal timing. Every engine is different, and will require different timing settings. Too many factors involved. But if i can help, from what i have seen on the engine dyno and the track, a good baseline for what you have is 36* total timing. Finding the optimal sweet spot for YOUR combination, which may be a little more or a little less, will require extensive tuning, either at the track, or on a dyno. Hope this helps.
@@vengeanceizmine9878 absolutely and I appreciate the info. We did start out at 36 and while testing different theories and settings I found 35 to be where we picked up mph. Wasn’t able to adjust anymore from there just due to other issues having to be dealt with. My ears are always open to anyone who’s willing to give advice. Ty very much VengeanceIzMine! I appreciate it.
@@jaredspear8140 No problem. I just enjoy helping when i can.
It's not just the number it's when it's all in at what engine RPM has to be right and that is all determined by many many factors
I didn't know about mixing the fuels like that thanks
I would love to see you and my friend Daniel Rawls talk you guys are so incredibly smart
