- HOW MUCH BOOST CAN I RUN ON 91 PUMP GAS? HOW MUCH TIMING CAN I RUN ON PUMP GAS UNDER BOOST? HOW MUCH MORE POWER WILL E85 MAKE THAN 91 OCTANE? CAN I RUN A SUPERCHARGER ON PUMP GAS? CAN I RUN BOOST ON A JUNKYARD LS? WILL A FORD GT500 BLOWER WORK ON A JUNKYARD LS? HOW MUCH BOOST WILL AN M122 OR 2.3L TRINITY BLOWER MAKE ON AN LS? CHECK OUT THIS COMPARISON WHERE I RAN A FORD RACING 2.3L TVS SUPERCHARGER ON A JUNKYARD L33 5.3L EQUIPPED WITH A BRIAN TOOLEY RACING TRUCK NORRIS CAM. USING A DEMUSE ENGINEERING ADAPTER KIT, THE 2.3L TVS WAS RUN NEAR 15 PSI OF BOOST BOTH ON E85 AND ON PUMP GAS. FULL TMING CURVES SUPPLIED ON BOTH, AS WELL AS THE DIFFERENCE IN POWER!
My daily driver runs 91 octane on an lq4 daily with a lil added ring gap and head studs. 12psi is max but it see's 12psi multiple times a day. Stock cam and springs and stock 317's. 9.5:1 compression and 2 very small 53mm t3 turbochargers with international wastegates and a factory duramax intercooler and radiator. I get 17 MPG highway and it has 600+ ft lb of torque from 2400 all the way to 5,400 RPM. Has done highway trips with 10k lbs behind it without issues
When does the boost start to climb with that setup?
A random stranger with no proof says out of vaccum at 1780-1830rpm / 1+ psi 1870-1900rpm / 5psi 2,100rpm / 10-12 psi 2300-2390psi
Hey Richard I just want to step up and say thank you for making this video because I am one of those guys that always wants to see stuff on pump gas really appreciate it thanks again
Glad I could help
Are you running this setup at all?
Dang 100hp down. Those roots and screw blowers REALLY like the vodka.
Closest station to me that sells E85 is 2 hours away, and they called the cops on me last time I filled up some barrels. So they don't get my business anymore, next one is another 20 minutes south. I paid $4.40 for 87 octane today when I filled up my 2500 so I can haul gravel tomorrow. 91 is just under $5.50 here. Last year when I got E85 it was $2.10, will be getting another 150 gallons later this month, my daily driver 65 GTO run on it. So I don't know what its selling for, but I bet its well below $5.50.
Back in 2007 when gasoline was $5 a gallon here, I started making ethanol. From '15 until last year I ran E85 rather than making it, it was dirt cheap and usually less than $2. This year I am working on getting the production up. The plan is to never buy pump gas again, not even for my generator when the power goes out here. I don't even build engines with pump gas compression anymore. Its 12:1 or more with all my engines. Still trying to get that much from the LS truck engines, but for now 706 heads on a 6.0 works good enough.
I would really like to see the difference in power at at 6, 8 ,10, 12, 14 lbs boost with different pullies ,etc. Great videos ,THANKS
Thanks for the 91 octane info. It's all I can get in my area.
Good to know Richard.....Tests like these are going to answer a lot of questions people need answered......Keep'em coming.
DATA!!!! We took over a 408 LS build from another shop that had issues, boat engine, small Vortec non intercooled deal. We reduced compression, swapped in a much smaller cam (6500 is no bueno for a family style river boat cruising for hours) and replaced the factory EFI with a Terminator kit. It made OK power but since it runs between 3000 and 4500 and has to run on 91 octane I was puzzled why I was stuck with about 9 degrees timing while under boost (about 6 PSI) but with this video it makes perfect sense, and how excellent is is to see the timing table. We have on order a Whipple LS kit with integral intercooler so it'll go back on the dyno for some tuning with the new setup. I don't expect to be able to run any more timing but we should be able to step up the boost a bit since it will have an efficient intercooler and river water as coolant. Going to take pictures of Richard's timing tables just for reference, it'll be interesting to see how different they look.
Thanks Richard, this information is basically unavailable, there are little hints you can find here on TH-cam (Joe Simpson has hours of TH-cam videos on Holley EFI) but rarely does it relate directly (lower RPM high load) to marine applications. You're AWESOME!!!
You are one of the most helpful TH-camrs ever thanks so much for your vids im 17 and thinking about running a 2.8lc KB on my bone stock 4.6 2v and i have so many questions that are hard to find the answers to even on google and you answered alot of them but i still have a few and im just going to wait until you go live again but thank you so much for making these videos
ask away-I always answer
Good vid, I definitely like the pump gas vids more than race gas tests, race gas is super expensive and almost nobody runs it in their street cars, which is what most of us have. I know it's a completely different animal because the power bands are vastly different, but it's interesting that you got 599 at the crank out of a blown 5.3 on 91oct, and I made 618 on a dynapack with a 3.0 (S366SXE) on 93oct. The magic of turbocharging, with its lower losses, improved compressor efficiency, and easier intercooler integration.
E85 is not universally available@@keith-jo6wg it's actually downright hard to find in some areas.
Glad it didn’t blow up. I’m really digging all the tests with the L33. Just in case my current set up is lackluster I’ll know where to go from there.
This is what I’ve been waiting for would love to see it dialed in ring gap, timing, boost to arrive at reasonably safe numbers
That's a big difference! Now I'm curious to see if reducing timing or reducing boost would be better for that combination on pump gas. Which one will lose the least amount of power?
Won't be much difference in final power, but the less boost engine will be happier. Pulling out a bunch of timing kills combustion efficiency and jumps up the coolant temps and EGT.
@@ChurchAutoTest exactly. Reducing boost also helps to keep intake temps cooler and the forced induction devices get less wear and tear.
I love this video!! Thank you. Very much needed. It’s nice to see what we can do with pump gas and how we can maximize what we can get out of pump fuel (premium 91 or 93 of course). Hope to see you do some more pump gas videos.
Great testing and results.
Now add WMI to the 91 octane!!
Skip the water, just go with meth.
When Brule did the 91/E85 comparisons for Engine Masters with the NA LS the timing was the same without much difference in power, slightly more with E85 but same timing. It basically didn't care what it was running on as long as the F/A was right, the timing was 29 BTDC no matter what.
Yes with the same inlet temperature/pressures the timing will remain roughly the same. Boost changes that.
@@jarlnieminen4307 the testing was done with the same engine, running the same boost, using the same intercooler, using dyno water in the intercooler. They should have made best power and lowest EGT at the same timing, if the Engine Masters test was valid. Personally I prefer to run at the lowest EGT I can because it extends the valve life significantly.
@@johnclary729 Thats not how it works. It does not matter that he ran the same boost the added cylinder pressure makes it advantageous to run E85 because thats where the 91 octane requires less ignition.
A follow up on this video could be a repeat with pump gas and water methanol injection. Us that can not get pump E85 may have the option to run w/m injection. I am going to do so on my build and would love to know the actual value of w/m to a boosted pump gas engine. I am building a LSA blown 6.0
I would like too see this as well.
on my sti I added about 100 hp and 6 psi of boost going from pump gas to meth injection with a 20 cc sprayer so about half way between pump and e85 values for the turbo I run on it. Not sure how much comparison to that is.
@@jeffwenke Well that's good to know, thanks for posting. I was kinda bummed thinking how much I would lose just being on pump. Im in the thinking stage of a ZL1 blower on my LS1.
i run 91 with over 15psi no problem. built 97 4.3(stock bottom end), Vortech V2-SQ, ford powerstroke intercooler.
yup , time for a bit of water inj , i ran my 215 buick /rover on 9.25:1, 20 psi boost , and 87 octane , with enough water ..no alcohol.. it's fine .
This is literally the same exact difference in power on my old 2012 gt500 with a 2.3 vmp tvs at about 18 psi. Made 702 rwhp on e85 and 598 rwhp on 93 octane. Boost for boost 24 degrees timing e85 and about 17 degrees on 93 and boostane.
Now show us those ol hotroddin tricks to be able to get the timing back up some on that level of boost!! I know you got some ol school tricks up your sleeve!!
Only really one thing left to do with this setup..... stroke the 5.3 to a 383 THEN let’s see what happens!!! ESPECIALLY on the 91!
Thanx Richard!
adding displacement will bring the boost down and push power up-less compression will bring boost down and power down, water/meth cam help ad timing
Awesome info for us poor fellas with no pump E85, but how is the power comparison to E85 and 91 Pump with meth injection. Thatvwould be another very useful video I fell, help us guys here in Canada and cold climates a hence to see good boost numbers and power.
...and this is why you setup a street blower car with a flex fuel sensor and ECU that can adjust for it
yes
Damn. 100 hp and 50 tq just from fuel. Really wanted a 91 build since that’s so much more available, but them power numbers are hard to pass up lol
Way to produce a new quality video!!!
I really appreciate your videos . How do i buy your books . i was thinking you got a lot of experience in tuning and building engines thanks Jim
not a tuner-but the books are available from Amazon
How about a test to show the best street tune for this setup on 91 octane? For example Optimize timing and boost levels to arrive at a safe reliable daily driver.
If you have to ask, consult your tuner.
bless you for this video richard!
I think that with pump gas meth injection could help with adding timing and keeping boost at 15 psi. Be nice to know air inlet temps below intercooler. You added meth to E85 blown engine. Did not to much. But the E85 does the same thing as meth injection. On pump gas it may be the answer.
WATER METH COULD ALLOOW YOU TO ADD TIMING-THAT WOULD BE THE GAIN
Love it as always!
If you ever take that l33 apart I'd love to know the ring gap that's in there now! Almost 15psi without checking the gap?! I'd be sweating EVERY RUN! 😆 Thank you Richard.
Same because im.gonna send it as well lol
For years, I ran a non intercooled Kenne Bell 2.2 Flowzilla on a 95 5.0 mustang gt. It was ran with 42lb injectors on 91 octane and is still running around on the same combo with the new owner. Its all in the tune for longevity but im sure a swap to e85 would have been huge for power gains on that car.
great video Rich
It was very interesting checking out the different fuels
What I gathered was Nitro is 1 atom 4 oxy methane was 1nitride and 3 oxy
Gas or octane is 1 nitride 2 oxy methane being a little more volitile
Nitro Metane the big boys use is Nitro Methane Hydrogen That amplifies it like H Bomb
Same way a Rocket goes to moon Then Supercharged
The E85 with Ethanol Has water in hydrogen that has a lot of oxygen but after it burns makes water and if it sets any length of time its a injector destoyer Alcohol drying up big portion of it The Hydrogen adding 10-20 horsepower
The thing with E 85 and nitro methane is they are burning Way more fuel to do it .
my 93 gas mix is 12 % Nitro about 40% nut or caster bean oil Working to lube like 2 stoke oil lubes piston rings its light oil
some have synthetic causing great heat burning off
40 percent corn Alcohol
The ultimate test would be if you can put All that Advance in ignition you do
with E 85 with my Nitro mix lol
because the octane is so high the 93 having alcohol in it and magic nut and bean oils lol
I say put them to Dyno
Great comparison!
Try the same test with deep-dish pistons!
IF: You could get the compression near 7-1, AND you could beg borrow or steal some "squish area" inside the CC >>> then you should be able to keep your 15psi boost on 91 and run enough timing to really kick ass.
I already know it works great - I just want you to show these kids that 6.5 to 7-1 mechanical compression is preferred over all others for horsepower ( gas mileage SUCKS with 7-1 though !)
that is a negative
At that compression you should be thinking like 40psi
@@taylorsrus9543 I'v tried 7-1 with a turbo on the street and it's a dog until you got 3-4 psi goin' and then Jekyll turns into Hyde.
But with a blower it's all good the smooth low end torque lets you do silly stuff like climb mountains in double overdrive when you really don't have that much oil pressure or water flow.
But throwing all that heat away eats fuel.
I mean the pipes be red all the way to the back bumper sometimes : D
Harry Ricardo did all the tests way back when and decided that IF you have unlimited supercharging flow and pressure available THEN for any given fuel octane rating 6.5 to 7.0 to one CR will give the most HP.
Wow that is huge. Sucks I can't get e85 in my area
It’s crazy this fbo 5.3 with cam and ford blower makes more hp than Zl1
Please note and be aware that "from the factory" the tune is optimized with fuel efficiency in mind and ran with ALL accessories.
Here it is not optimized for efficiency, just maximum for comparison and it is not ran with any accessories.
@@ericvaughn2875 yes I know that but still makes more than 650hp with accessories I bet.
@@realshidd3062 Or look at it this way. Run an LT4 at cold temps, with dyno water for the intercooler (which is a big problem on LT4s), long tube headers and no cats with an optimized tune. Guarantee it'll make way over 700 hp at the crank. Just running E50 on a stock LT4 with long tubes, intake and tune will net out an additional 100 hp over stock on a chassis dyno. Really no comparison. And the LT4 blower is a tiny little 1.7
th-cam.com/video/yHHLDDrIce4/w-d-xo.html
Yeh the accessories did not cost but like 50 tq.
I get ya tho. Idk much in the new LT stuff but I'll be an LS fan for time to come.
Timing view definitely helps us backyard tuners
Every engine is different. Testing for best timing on your engine, in your car, with your transmission, with your converter, your exhaust, blah blah blah is what will help you. Learning to read a spark plug and timing YOUR engine according to the fuel you will run will help you. Blindly using Richards timing curves will probably get you in trouble. Too many variables.
Richard told you specifically NOT to us those timing curves
@@richardholdener1727 so many watch these videos and think it's the same engine, same boost so I'll use this timing or this afr etc. What they need to understand is there is no getting around testing to find out what works best for their exact combination. What you can get away with for 20-30 seconds on a Dyno with a wot pull at 130-140° coolant temperature is almost a guaranteed way to cause engine damage for these guys. They are looking at your videos for tuning info and taking it as Gospel and that's just bad. I'm grateful for your time, efforts, and content. Just hate to see someone blindly clone what you are doing and ruin an expensive engine.
Get down when you hear that sound! Boost!
Great stuff , what about 93 octane, do you think this would add a few HP or just buy you some added engine protection ?
Added detonation resistance no more power.
Definitely adds power. Especially comparing the California 91. I find non-ACN 91 is worth 1-2% on a boosted engine (depending on how hard you're pushing) and 93 is worth another 2-3% above that. So you could easily get 4-5% more power tuning 93 vs. ACN91.
@@ChurchAutoTest nice because here in Mississippi we don't have 91...just 87,89,& 93
@@sixx6sixx107 You're very lucky :)
@@thatturbotruck Correct, but with increased knock resistance means you can run closer to MBT, which = more power.
Great stuff Richard! I’m assuming that when you’re going from e85 to pump gas you’re accounting for the stoic number changing between the two? How do you end up at 11.5:1 on e85? I’ve read it’s easier to use Lambda when switching between fuels but AFR seems to be the common number used. I always like learning new stuff! Keep it up!!
we use the gas scale so the amount of fuel supplied for e85 increases to achieve the same af
Great comparison..
Hey Richard I've got a mark 4 454 two bolt main will running a 6-71 blower with 3 to 6 psi boost kill the engine I'm not going to race it just play with it and use it as a daily driver
will be fine
It’s a big block it ain’t that fragile and you’re not running a 12-72 blower
Thanks guys that helps alot I'm 62 lost my wife two years ago and this was our play toy. Ok mine again thank
Mr. Kline, very sorry for your loss, I know the loss at too well. You'll be amazed just how strong a stock bottom end of big block Chevrolet is.
My 1 recommendation is, and I'm assuming you have a cast crank, is to have a good Machinist mill a second key way in the snout, and get a harmonic balancer to match.
This isn't mandatory, but it's good insurance for a minimal cost, especially while it's apart. Good luck Sir 👍
T.S. RACING
@@t.s.racing I'm planning to get forged crank , rods , pistons I just want it strong enough if I'm at a car show and hit hard to do burnouts. Just to have fun my wife would have had fun doing that. And thank you
I still can’t find a website for Demeuse Engineering. Have you tested 91 with water injection? I remember some of Holley’s ECUs can control it. For 91 octane a 6.0 truck motor might be a better choice. Also you might compare that blower with a Eaton m-122 since it would much less expensive. Maybe the 2.3 as well.
1 would like to see what would happen if you added meth/injection to the 91 octane setup
Boostane works for my 11.15:1 lsa supercharged lq9 in my nova…..with 20 gallons of 91 the 32oz bottle of Boostane will bring it up to 97-98 octane…..if you can’t find Boostane you can settle for Torco which will yield you 95-96 octane from 20 gallons of 91……
have you lab tested the octane change?
@@richardholdener1727 no sir……but I can definitely tell you,,the engine approves
I have a question. Obviously it would be easier with a turbo/boost controller combo, but have you ever tested to see if the horsepower loss realized pulling timing was more than the gain from the extra boost at different levels? Basically on pump gas with lets say 10:1 compression, what is the boost level that is a point of diminishing returns due to timing losses.
Oh that poor little belt I was waiting for it to give up the ghost!!!
You had made the point during the video and I believe you emphasized about not running that much boost on a PD with 91 for the street. Just for curiosity sake, could you get away with more timing with a 700HP turbo, all else being equal? Less parasitic loss, perhaps less heat = more power at same timing or even more power if the turbo setup can add timing?
BOOST WOULD BE LOWER TO MAKE 700 HP WITH THE TURBO SO POSSIBLY
@@richardholdener1727 Thank you! and thanks for your advice/comments on the live feed!
Love the videos!! Can I run a LSA blower on a LS1 with stock heads and stock compression, I think it’s around 10.1? Or would 317 heads be a better choice because of the combustion chamber size?
either will work with the right timing
Depends how much boost low boost stay stock heads my ls1 z28 made 491 hp 471 tq 6 psi procharged 317 you will need more boost to make same power since you will drop to 8.5-1 or so in compression
@@utahcountypicazospage5412 I think the LSA puts out about 9psi stock.
Looks about right. I run my 2650 equipped, but otherwise stock LSA at about 17 psi peak. Comes in around 13-14 psi at 3000 rpm and climbs from there. A little lower compression than your 5.3. 1/7/8" headers, 103mm throttle body. I run 25-26 deg peak ignition on E85 (it'll take 30 without knocking, but almost no gain so why beat up the bearings) with 195-200F water temps. On 91 deg I run 12-14 deg less (11-14 deg total) than the E85 map on the street in a 4000 lbs car. I run a 0.83 lambda on E85 and about 0.76 on 91. 17 psi is definitely too much for my tastes on 91, but I haven't perfected my boost controller yet, and I run 91 very infrequently. Total power loss is about 125-130 whp going from E85 to 91.
26 DEGREES ON E85 AT 17 PSI?
@@richardholdener1727 Yep. All day long. Motor is at 135k miles now without being opened up. Best 1/4 mile trap speed is 138 mph on street tires, 4300 lbs with driver. We've talked about timing before, sometimes I wonder if its being measured a little differently. I'm on stock ECU and sensors while you're usually running aftermarket ECU. Perhaps the indexing is a bit different? If I ran 21 deg I'd lose 50 hp easily.
@@ChurchAutoTest Sounds pretty normal. If you are on the stock cam and heads, your boost numbers are probably inflated so your cylinder pressure is not as high as a good flowing setup would be at that boost level.
I build all of my cars to be ran off of no more than pump 93. Its easy to get and my cars are built to drive. If e85 was more available in my area I would consider it but I also dont like that its unreliable as far as fuel quality goes depending on wich station you go to and time of the year.
Trying to make a habit of getting prepared to watch to your video's by letting the commercials roll brother. Everyone try to make a habit, especially when video is starting. Let's make Richard the next Mr Beast $$$$$
THNX
Just going to run to the back of my 2 car garage grab a Ford racing blower
Put it on my junkyard 5.3 Ls. That is setting on my engine Dino
Just happened to have cam I found setting next to the blower, it had some high dollar valve springs
To use on my high dollar cam
A good friend gave me a high dollar adapter kit to bolt on the blower
A set of high dollar headers
Everyone should be able to do this
Just the engine for my street drive 100,000 dollar 1957 Chevy convertible
Then why would I cheep out on my fuel?.
For the kiddos out there, gasoline burns faster than alcohol
Therefore the more alcohol the more timing to be able to produce the power gained by using alcohol
That is slower burning slower. Plus it takes more alcohol to produce the extra power. Therefore bigger jets or more fuel pressure. And you might run higher compression like some kids are doing now.
Viscous circle
My dad had a farm pu with lp gas , always wondered what would happen with high compression pistons 13 to 1,
And more timing, but of course would’ve work cause always had to switch back to cheap gas when you ran out of butane.
Damn. Us ford guys finally had a source of reasonably priced power. Now comes the @Richard Holdener tax.
Yep, just like all the ls guys that has to run fox bodies! Ford Chassis, now Ford blower, why not just build a Windsor and be done...
I know this is off subject
But one thing I would like to see is a truck Norris cam in the LS 496 if they even make one
WHY
@@richardholdener1727 because it seems like a easy monster on pump gas with the same affects of the Truck Norris to the 5.3
Here’s a question for ya.... which setup gt500 m122 or Cadillac m122 makes more power? (On pump gas) and which setup (aside from the blower itself) is more cost efficient
Thanks rich
THE GT500 BLOWER HAS A BIGGER INLET-PUMP GAS LIMITS BOTH
@@richardholdener1727 as always, thanks for your response
I’m grateful for all the testing you do, and videos you make!!
I believe these lags can be augmented by a tune relative to the octane/alcohol content
Which supercharger has the biggest displacement and which one do you prefer based on power and how expensive it is to installed
Compare 91 to 93? Add fuel additives like octane booster? Does any of that really make a difference? It would be cool to see you test the fuel grades and additives, store bought additives from your local part store.
So your saying there’s a chance :p wow what a power swing.
Yes, add water injection.
I'd be happy to just watch a continuous shot of the engine doing the pull. The still images cut in to the video don't add much for me. 3:02
I think I missed what stock tq/hp #s were on that LS, na.
I’m building a Toyota 4 cyl street engine with 150hp na and just want to be able to double the output on Costco 91 with a turbo.
Also, what about reducing compression ratio a little?
My friend had chrsler hemi in his boat. He was running 89 to 91 octane gas with flat top pistons @7.5 cr with a 671 blower and 18 to 22 lbs boost puting out 750hp+ it had a Norris solid roller cam. He didnt want to have to run expensive high octane fuel like other boats.
Sweet test!!! So any guess where same horsepower can be reach if boost is reduced and timing is optimized on the 91? Just trying to form a boost/timing curve in my head…
Usually boost is worth more than timing.
boost is better than timing
You should test on better flowing heads
Hah, in Poland all we got at the pump is 95 and 98 (yours 91, 93 I guess). So we do run 15, 30, sometimes 36 psi, on our 98 octane :) I think you could have run bit more timing on 91, depending on IATs, but there is a brick inside.. In my european Ford Granada I run a 4.0 ohv explorer engine (all stock, 9:1 CR, just added 12.9 grade head bolts) on 98. Twin tiny turbos, recently at 1.5 bar at the top (22 psi?), 21deg of timing, 40degC (104F) making 473hp at the crank
the octane measurements are different in other countries-your 98 would be like 93
@@richardholdener1727 yes, I know, still I think You could push it little more on 91, but I'm not an expert (You are :) ) and I completely understand keeping it safe instead of risking. After this video, I started thinking and having fears if I'm not pushing it to close to knock :) Maybe on next dyno session I will retard it 3-4 deg and check out how it reacts
Could you possibly do a walk around of that blower manifold? Unless it was in the live stream. I was looking for somewhere to get a price idea on it and I can't find it. GT500 blower on a 6.0 for my foxbody sounds like a riot!
The adapter plate is 2500.00. Very expensive.
This making want to do for my 03 tahoe hell or my 944 with a swapped ls
I don’t understand how this package only picks up 172hp on 14 pounds of boost. I always understood that power should double with 1bar(14.7psi) of boost. That would be 854hp, I understand that the blower consumes some power, but is it eating 255 hp. I don’t know why anyone would pick this combo over about the same investment with a single turbo, plus it could run 20-25 lbs of boost on E85 and with a flex fuel sensor and turbo it would pull back the boost for 93 pump gas, plus it would make much more power with no loss for the blower drive.
Looked up the price of the adapter kit. It's 2500.00 bucks
Hey Richard, what cam is better for boost “Sloppy Stage 2” or “Truck Norris”??
that video is up
Quick question Rich.... Do you think running an heat exchanger is a must with this setup???
YES FOR STREET USE
I keep being tempted to try a blower like this but a turbo at the same boost just always seems to kill it. Blower tax is real
Turbo tends to be better. But if the car is a manual blowers can be really fun. And really heavy cars tend to be more streetable with blowers. But if you're racing, turbo FTW
Each have their pros and cons. Don’t be afraid to go supercharged though. If cooled properly they are great. Unfortunately most of the issues with blowers is heat from inadequate intercooling. Most kits don’t have nearly enough cooling power. All this heat is why blower cars can respond so well to e85. It’s a way around a lacking intercooling solution, allowing it to have the timing it should be able to have in the first place.
@@gforce_117 100%.
Packaging a water/air intercooler underneath a blower is always a compromise. They usually lack adequate cooling capacity and the length of the intake runners need to get butchered to make room for the intercooler.
It would be a real eye opener to test a positive displacement blower mounted as an accessory much like a centrifugal, and have the boost plumbed as a blow-through on an engine with a highly functional water/air intercooler and manifold with typical N/A long intake runners.
Then unbolt the blower and replace it with an appropriately sized turbo for an apples-to-apples comparison.
@@jacksonjdr94 exactly! I run 15 gallons per minute in my PD supercharged intercooler setup at just 10psi. Going to do testing soon but that should be enough to keep IAT from climbing much at all during WOT. So imagine 15-20+psi and how much water flow that would require… Most PD kits come with pumps that flow 1/2-3/4 of that 15gpm I run at best and there are many of those setups running more than 10psi!
THE PD BLOWER STILL REQUIRES THE SAME AMOUNT OF POWER TO DRIVE IT-IT WON'T DO WHAT A TURBO DOES BUT THE LONG RUNNER INTAKE WILL HELP
How's the stock tensioner holding up? Excessive belt slip?
👍💪
I’d be interested in seeing if the engine was experiencing any knock and at what load/rpm/timing. (For the science) of course. On a street aplication you do not want to be riding the “edge” on detonation.
there was no knock or it would have let us know
Took my engine back out!!!! All the rings were atleast .026 gapped, i could have just sent it.. but you mever know
I’m going this route on a 416” LS3. Probably only 8-10 psi. What timing would u recommend starting at on 93?
Is there any way to measure the clearance from the valley cover to the top of the blower? I've got very little hood clearance and this looks so close.
Yay.
Anyway that you could equalize the volume?
So the obvious next question is: ok, can I back the boost down to 10psi, roll back in 6° and get 50hp or so back on 91.
Woowww Rich... That was a major question of mine... 👀👀👀👀15lbs😬😬😬... Even though I'm on E85, that's still a lot aint it... And that's also a bigger pulley your using... Is that safe for a stock bottom end.. How do we get this blower down to 10lbs???
since we made over 1500 hp on a stock bottom end (with ring gap), we are fine at this level-I dropped it down to 5 psi in the next video
@@richardholdener1727 👀👀👀😬😬😬1500??? Daaamnnn... Bet that up Rich😁😁😁💯💯👌🏿
Knock happens at high cylinder pressures. Because you have a falling torque curve you could probably feed in more timing without an issue. Also at higher rpm there's less time for knock to happen.
What ? Not at all knock is detonation wether from boost heat piston heat not enough octane which is a retardant for ignition high rpm is we’re knock happens the most and will blow an engine to pieces
What size belt did you use do you remember?
4.8/5.3 with a lsa be cool. testing cams.
Richard wouldn't you expect to see more than 700hp with 14lbs of boost from an engine that made almost 450hp NA?
yes-with a turbo
How does Roush get 750 crank horsepower out of their third gen coyote with the 2650 Roush supercharger on 93 pump gas with only 10 lb of boost
KNOCK SENSORS
@@richardholdener1727 so the knock sensors let it push the timing up ?
Do they have an adapter for m112 eaton supercharger
Hey Richard I have a 04 GTO with a Ls1 5.7 I can get a m122 cobra supercharger and would like to put it on my GTO is it possible and what would I need in order to do that? I will make a video as I don’t and send it to you if you help me with the process. Thanks in advance I love your videos
you need to fabricate an adapter plate at the very least
And People say you can't run boost on a engine without ring gap.
C'mon Richard, lets do a water - meth test and get some of that timing back!
I guess that settles that , could you hear it detonating at all when you put the timing back in with the 91 octane ? I would have been terrified.......
NO DETONATION-WE ONLY RAN THE 91 WITH LOW TIMING
By any chance have you done any tests on cathedral port 5.3’s with an LSA supercharger?
NO SIR
If you optimized the motor for e85 before adding boost would you make more power? As in shaving the heads to increase compression ratio. If you increase the compression ratio would timing decrease?
IF YOU ARE LOOKING TO OPTIMIZE THE MOTOR FOR MORE POWER-ADD A BIGGER CAM
@@richardholdener1727 And lower the compression half a point, not raise it? So a little more boost, slightly less compression (can we get more timing in with less compression? I’m still learning here), ring gap, port the heads with more valve, more cam (g5x2 on a 114? .595/.608 232/240) or even more cam in the .620’s and 240ish duration? With all of this stuff done, would the little 5.3 benefit from larger exhaust primaries? Oh man I feel like piston squirters and forged pistons could help at this point. I’m a little afraid of high iat’s with pd blowers. I’d like to something around this (e85) power level in my 944 turbo LS car.
You’re the best Richard!
@@Russell_and_Rosko A LSA with a mid size cam and headers would make more than this did. Would be a cake walk with a turbo. Probably wouldnt even need a cam.
I would like to see chevy stock 2.0 turbos on a 3.6 v6 to see if it would gain hp or stay the same.
It would gain hp. You're adding more air to an engine than what it can take in on it's own. You would just be limited as to how much boost and air you could add because of the turbo sizing
I wish you can try a vmp on a 6.0
By chance can that adapter allow you to test Ford intake manifolds in a naturally aspirated configuration on an LS engine? Just for shits and giggles lol.
No the blower flange is its own unique thing.
no
