call me crazy but i would much rather see real world problems and people working to solve them like this rather than a perfect "throw it on the dyno and get numbers" video that most people put up because they edit out valuable information and scenes like this that can actually teach you ALOT
Yeah, makes me happy to see I'm not only one with less than perfect moddings and hours and hours of stupid fault finding. Just fixed ecu from boosted E85 ford sierra... alcohol melted glue inside ecu and solders rattled loose :O
funny to see the fould finding proces, and thinking with that, talking to my screen here,after the miss firing, its the air intake on top off the carb, its the air intake!! then let them finding it out it was that! lol
My favorite episode on any TH-cam channel for a long time, really appreciated the work of Nate Mailhot. This proves how useful dyno tuning is after en engine modification or a complete build
Less than 15 minutes in and already scared of damage on the engine. 16-1 on AFR is just ASKING for trouble! Why this guy was trying to "power" through when the engine was saying enough was enough was scary to watch!!
PantherSerpahin it wasn't technically lean if you watch later in the video. It was missing and the air from the missing cylinder was causing the o2 to show lean but it was actually rich.
I think they meant it was showing lean because the fuel was not being distributed correctly due to the horrible hat design. This was causing a very litle to no fuel mixture to some of the cylinders
Fabs 15 and all it takes is a bad fuel flow and suddenly you are going into pre detonation issue which can send rods and pistons through the bottom/side of the block
You really think a couple seconds of a lean condition at mid RPMs and at most the time 50% throttle will hurt the engine??? Im not worried at all, the AFR was right at every other RPM to cool the cylinders back down and excess heat was not an issue.
I think the troubleshooting added so much value to the video! Thank you so much for this look inside the dyno operation world! I've always wanted to see a sort of candid day engine tuner video like this
when tuning an engine, especially a boosted one, you should always "power through" the lean spot........ALSO, do it a couple times.....you know.....to make sure.
im so used to the pretty edited dyno videos i thought something was wrong. this video gave me a lot of anxiety but I'm glad it worked out for you, and you got one hell of a small block there.
This has got to be one of the coolest things I've ever seen! I can only imagine the feeling of satisfaction of being the one to create that.. or own it.
It's great to see people, who know what they're doing , troubleshooting engines. You learn SO much from watching it. Especially since the dyno dude explains so well. I'm only 20 minutes in and I'm hooked. Great video for engine builders!
Congratulations Eric and Kalvinator Engines! Like many, I've been following this build with mounting excitement and it's great to see this come roaring to life.
The moment you realize a half running engine makes triple the power of your daily and even with the most generous estimates more power than the stroker you are building.
This may be one of the most interesting videos about tuning on a dyno on TH-cam because many just tell you that a dyno gets numbers and they show a dude sitting down looking at a computer. Although this is a video in the build series you actually get some sort of look on what the hell these guys actually do to get an engine to run right. I mean it's different bc were talking about a turbo charged carbureted motor so there's a lot more involved than just a naturally aspirated application.
+EricTheCarGuy I actually just went through my first build just as these videos were coming out and they were very informational. Unfortunately I didn't have the experts like you did but everything turned out great considering I was all naturally aspirated. Thanks Eric
You were not lying yesterday! I really did enjoy the video! Not much has changed since I graduated there 7 years ago! It's refreshing seeing actual real world experiences on an automotive channel! Keep up the good work man!
Didn’t expect to wake up today and watch an hour long video while two kids are running around in my house lol. The amount of detail and the steps taken to troubleshoot the issue had me glued to the screen lol. It is really interesting to see all that goes into this process. Thanks ETCG.
"well we finally ate lunch" i laughed, i was dealing with similar symptoms, took me ages to figure out as the project was 2 hours away from my house and I only made it up there once every few months
I miss the good ole days! Raw fuel,carborator tuning,reading plugs,changing dwell, setting points. It reminds me of my early days of automobiles. I witnessed the incorporation of throttle body injection,then fuel injection,stuff that was already being used in Europe on high end cars back in 1975. I still love the sound of the dyno and hearing that turbo on that engine is pretty cool. Fiddle farting around with something we played with back on my brothers cars only to take it off and go back to running without. When you eat drink and sleep engines,sometimes taking a break can unscramble your brain and get you to rethink an issue,sometimes something simple stupid,sometimes not when it comes to trouble shooting. Nice strong engine ! Like I said,I miss those days.
This must be one of the most exciting dyno videos I have ever seen, proper detective work, I couldnt take my eyes of the screen for even a moment. I love it!
Nice to see the process of fault finding. Most dyno runs shown look as though all they do is bolt the motor on and pull the handle on a full power run first go. Hope you have plenty of cash for new tyres Eric.
Eric, all of your videos are amazing fun, but this was one of the coolest and most informative videos you've done to date. Thanks for the awesome content.
Yea, I regret that too. Next time I'll plan more time for shooting. If we didn't have all the trouble during assembly, I would have had time to catch it all.
love that you put up the full video. Too many people on internet stuff make it seem like they never make a mistake and everything goes perfect every time when reality is more like this video depicted.
I'm happy you included all the headache that is a reality with custom parts combinations and even some stock vehicles with oddball problems. This is the reality of troubleshooting and trying to make a living when the machines will not cooperate.
The progression of thoughts are "nice rumble, sounds powerful", "beginning to climb", "oh yes", "really?" Oh wow", "holy jumping cow", "that's mind blowing outrageous" and then roll about laughing like a demon when you realise it's still got more to give.
I don't like American V8 engines, I don't like carburetor + turbo, I don't like single camshaft, I don't like 2 valves per cylinder. But what a great build, great people and thanks Eric for sharing this with us. Thanks from the Netherlands!
usually we only see the end result and they make it look like it's easy to dyno an engine. this is a true video on how this process works. very interesting and on the edge of my seat. have to stock up on tires now eric ;)
subscribed.....this was absolutely brilliant. as a weekend wrench warrior, and a engineer, this was fantastic to listen to the troubleshooting discussions
I won't lie, I'm kind of disappointed to miss out on the top end in the awesome detail you've covered the bottom end with. Scheduling issues happen, though; I can live with the rest of Oliver's assembly. Keep up the great work, Eric!
Remember folks, Oliver harks from a time before laptop tunable EFI. Carburetors may not be any good in the modern world, but damn 440 actual KW is a bloody good effort. That's almost half a Megawatt! And he probably makes it on humble octane liquid gas. Awesome effort Eric.
Eric, I really enjoyed this video. I always like watching a master at work, weather a dyno master or hell someone who has mastered the drive thru of a fast food chain, was a enjoyable experience. Stay dirty!
I vote this as the best video your channel has ever produced. Primarily due to the inherent life lessons; cooperation, communication, perseverance, among others. Great job Eric. Can't wait to see that beast run.
I don't comment much, but I've been subscribed to you since early 2009. It's amazing seeing all the accomplishments you have made and watching this channel grow. God has blessed you Eric :)!! Im sure you recognize it already lol but he really has. I'm proud to be one of your many supporters.
There is something very satisfying about seeing an engine come to life for the first time. I was just giddy with excitement on dyno day for the SBC My dad and I built together for his Stingray Corvette. I'm pretty sure I know how you were feeling that day Eric. You've got a real nice engine there. Would love to see some videos of Oliver.
@@yolofullsend dude, the more I watch the more I'm shaking my head. I wonder how many engines this guy has blown up. Sees AFR hitting 16.0:1...gives it full throttle.
most anticipated video for me. nice job! I'm going small twins on a SBC using a fitech tbi efi unit. Your build reminds me of the details I need to remember. Thanks ETCG!
pfft i paid 600 and got my car back better than the guy i paid 1400 too. dyno tuning is about way more than the cost it's about going to someone who knows what you've got and how to deal with it.
Apart from the intake problem, that is one very special engine, im not supprised it took a while to get every variable optimised, never an easy task. Coming together as a dedicated team, not letting go untill the engine performs :-D. You enjoyed that time eric, worth every second.
This video was very helpful. learned something very valuable in this video. I loved the trial and error. Also how they finally figured that such a simple thing such as direction of air flow could have such a crucial effect on how an engine runs.
Oh man i totally forgot Eric. The problem you were having could have been related to the spark plug gap. As boost increases, the spark plug gap needs to be decreased.
That turbo will be down on optimum power, because the long exhaust pipe will be feeding it relatively cool exhaust gas. The turbo lag will be more pronounced too. The closer to the manifold the better, both for power output AND for less lag. (torture for the oil and bearings.. but if ya wanna go fast...). Even so, I've got to say, that's a sweet engine ! The dyno bloke is super switched on as well, that was nice to see. He wasn't just a 'dyno operator'.. but really knew what he was doing. Impressive, keep 'em coming. Great video Mr Car Guy, cheers. . .
*He should have gone for lunch when you offered.also Eric this motor gets a cracked piston ring groove and you end up stripping her down again. I'm from the future.*
Nice vid man, I think you just became my favorite channel! Some real troubleshooting on an engine dyno is not something you typically find on YT car channels.
So awesome finally getting to see the heart of #projectfairmont getting finished and tested, after what? Two, three years after getting the Fairmont and all the videos of getting it fixed up etc, the dream is getting closer to reality. Can't wait to finally see the finished product, Eric!
As i was sitting here watching you guys taking every possible stab at figuring out what was wrong as soon as i thought about that hat and how rugged it was and may not provide the smooth airflow into the carb...boom u guys figured it out...wish i knew earlier so i could be a keyboard warrior and say i knew it before all u guys :)
I recently built a LS 2 based twin turbo engine using a Holley engine management system. Tuning was beyond easy. Through the Holley EFI, boost can be controlled with their boost controllers. This video is a reminder of just how far we've come. No trips out to swap jets, set timing, and boost parameters. It took just 3 hrs to tune, and most of that time was deciding how much power I wanted to make and where that power is centered. 5 levels of performance were saved into the computer's memory and can be recalled in just a moment via a laptop trackside. I have it set for 650/620 hp/tq street, and as I increase the suspension's capability, I'll use the other tunes (up to 1045 hp / 950 lb ft) for the strip.
All these armchair mechanics triggered by this video series. From the dyno to carb vs Efi, from the oil pan to the a/f ratio. You'd think it was their money and project!
Scares me when stuff like this happens. Don't hurt a man's brand new engine :/ Lean. Just add more throttle? Hold at 16+:1 AFR..... Skeery. This is like part guessing when you have a problem with thte car instead of diagnosing and fixing. Just throw crap at it and see what happens? 41:05... smaaallll boost leak lol. Commenting as I go here.
Air is lazy, and resists itself going in a straight line, much less making a radical turn. The only thing that flat hat is good for is filter relocation for cool air intake/no boost as this experiment proved. A blow thru carby can be twitchy to setup [boosters and air bleeds need to see the same pressures on top], but this episode might help the injector fans too: velocity and wave effect/backpressure may tweak effective boost values seen in the ports differently along the rpm range. I'd like to see a dyno test with heads modified to chart flow or pressure seen in each intake runner on the heads to compare aftermarket manifold designs flat spots in certain rpm ranges on a typical v8 injected motor, but that may be more trouble than Eric would like to get into. [There's always cool looking stuff out there that doesn't actually make the grade]. Mainly - to compare front vs. rear cylinder performance VE at various engine speeds. I note alot of OEM manifolds always add extra intake runner length and seem to pay attention to minimum turn radius details to a point that seems silly to anyone who never turned a wrench or tuned anything.
amazing engine! thanks for all the videos eric ive been watching for years and i give u major credit man! SO many people complaining about how long everything is taking you can tell they never did a build before! great job man keep up the good work!
EricTheCarGuy yes EFI has a bit more control, but the reason I said gale banks Pontiac Firebird is cause it has a twin turbo big block Chevy and has a carburetor and he wanted to go 300 MPH, so power is still there with a carburetor
Yea, carburetors are just fine for making power. I think it's just that most people don't know how they work, or how to tune them is the reason why they don't like them. Hence the reason I asked Mr. Mailhot in the video if he thought tuning carburetors was difficult.
Extending the fuel bowl vents with steel brake line will help the issue. The carb was the biggest issue. Boosting a carb is a challenge! It was a huge relief seeing it start acting better by the end.
The carb vent tubes needed to be shortened approximately 3/8 inch to clear the carb top hat, not extended. The carburetor was/is not the problem, it is the cheap, poorly designed chinese carb hat.
RedneckRectum I was pointing out an alternative is to extend and/or turn the bowl vents routed towards the hat inlet. As long as it's running good it all worked out.
call me crazy but i would much rather see real world problems and people working to solve them like this rather than a perfect "throw it on the dyno and get numbers" video that most people put up because they edit out valuable information and scenes like this that can actually teach you ALOT
It's so great when people 'get it'. Thanks for the comment.
your welcome sir :-) keep up the great videos
Yeah, makes me happy to see I'm not only one with less than perfect moddings and hours and hours of stupid fault finding. Just fixed ecu from boosted E85 ford sierra... alcohol melted glue inside ecu and solders rattled loose :O
yep.. Motor trend does a series with dyno comparisons..they NEVER have problems LOL
Southern Mechanic I completely agree with you as well.
am i the only one on the edge of my seat watching this?? AWESOME
you and me both
funny to see the fould finding proces, and thinking with that, talking to my screen here,after the miss firing, its the air intake on top off the carb, its the air intake!! then let them finding it out it was that! lol
I was on the edge of my seat when his AFR was in the 16's and he kept opening the throttle...
srd240yo I hear ya, I was on the edge of my seat, too, especially after they figured out the hat issue!!
yep i was laying down
My favorite episode on any TH-cam channel for a long time, really appreciated the work of Nate Mailhot. This proves how useful dyno tuning is after en engine modification or a complete build

Im not worried at all, the AFR was right at every other RPM to cool the cylinders back down and excess heat was not an issue.
That computer seems to be sort of drive by wire, so it controlled the amount and limit of RPMs.
I think the troubleshooting added so much value to the video! Thank you so much for this look inside the dyno operation world! I've always wanted to see a sort of candid day engine tuner video like this
when tuning an engine, especially a boosted one, you should always "power through" the lean spot........ALSO, do it a couple times.....you know.....to make sure.
especially during the most loaded area of the powerband. just hold it at 3k rpm while its 19:1 on pump gas. it will fix itself. lean is mean
Disregarding the analog torque output meter is also very important. Just run it again and again...
Wow, I sat here and watched the entire video. Its really cool watching the troubleshooting and then finally seeing the end product. Great Video !!
im so used to the pretty edited dyno videos i thought something was wrong. this video gave me a lot of anxiety but I'm glad it worked out for you, and you got one hell of a small block there.

such a special feeling when you get your new engine dialed in . CONGRATS BROTHER
That guy on the Dyno seems to really know his shit. Good job guys!
By far the best video in this series so far. Patience and persistence paid off in a big way in the dyno shop.
I think I knew what the problem was from the beginning it just needed more cowbell it seems that it couldn't get enough cowbell
Miguel de la cruz Awesome.
nailed it.
severe lack of CB.
Lmfao!!!!! Nice!!

Congratulations Eric and Kalvinator Engines! Like many, I've been following this build with mounting excitement and it's great to see this come roaring to life.
That moment you realize a half running engine makes more power than your daily
Right?
The moment you realize a half running engine makes triple the power of your daily and even with the most generous estimates more power than the stroker you are building.
Even when your daily is still a V8 and its still making more power
Mr. Mailhot is a fantastic instructor with a ton of knowledge and experience. One of my favorites I have had for sure!
Great video! Very knowledgeable folks and really enjoyed seeing them troubleshoot through all the steps.
Damn eric you made a freakin' torque monster. I know seeing those figures made all that frustration worth it.
Indeed it did.
This may be one of the most interesting videos about tuning on a dyno on TH-cam because many just tell you that a dyno gets numbers and they show a dude sitting down looking at a computer.

Have a look at Nicks Garage, does old school muscle V8, dyno runs etc.

My favorite ETCG video ever. Could not stop watching. Where'd the evening go?
honestly one of the best videos on youtube. I just watched the whole video glued to my seat, so intense
"well we finally ate lunch" i laughed, i was dealing with similar symptoms, took me ages to figure out as the project was 2 hours away from my house and I only made it up there once every few months
Awesome troubleshooting session, very cool headed, pro level dyno operators👍
This was so cool, thanks for sharing Eric. I love learning :)
That was awesome! Nice footage and loved seeing the dyno pulls. These guys really know their stuff... brain surgeons of engine tech!!
That was intense, I was shitting bricks, I was sweating profusely but.....they did it......they finally ate lunch.
LOL :D
Awesome! So glad it worked out Eric, sounds amazing too and looking forward to seeing it drive!
I miss the good ole days! Raw fuel,carborator tuning,reading plugs,changing dwell, setting points. It reminds me of my early days of automobiles. I witnessed the incorporation of throttle body injection,then fuel injection,stuff that was already being used in Europe on high end cars back in 1975. I still love the sound of the dyno and hearing that turbo on that engine is pretty cool. Fiddle farting around with something we played with back on my brothers cars only to take it off and go back to running without. When you eat drink and sleep engines,sometimes taking a break can unscramble your brain and get you to rethink an issue,sometimes something simple stupid,sometimes not when it comes to trouble shooting. Nice strong engine ! Like I said,I miss those days.
That's a great thriller, kept me on the edge of the seat the whole time :) Good job, loved the tuning guys!
That guy Nate seems like he lives in that dyno room, he knows his theory tho haha. I'd trust him with my motor.
This must be one of the most exciting dyno videos I have ever seen, proper detective work, I couldnt take my eyes of the screen for even a moment. I love it!
that is a bad boy there Eric you're going to be passing everything up besides a gas station
Nice to see the process of fault finding. Most dyno runs shown look as though all they do is bolt the motor on and pull the handle on a full power run first go. Hope you have plenty of cash for new tyres Eric.
And here I though carbs/distributors were supposed to be simpler and easier to setup. Give me coil-on-plug and EFI any day, LOL.
opened my eyes too lol
It’s because he’s doing a turbo blow though setup. Carbs are a LOT simpler than any efi system.
Eric, all of your videos are amazing fun, but this was one of the coolest and most informative videos you've done to date. Thanks for the awesome content.
This was an excellent video of the process of tuning an engine for maximum power.
Not really. 90% of it was fixing an error.
I loved seeing the troubleshooting,Eric!!! Thank you so much for these videos!
That was some deep intense dyno drama in the beginning. Enjoyed the video. Shame we won't get to see how the top end was put together
Yea, I regret that too. Next time I'll plan more time for shooting. If we didn't have all the trouble during assembly, I would have had time to catch it all.

because they are idiots
Because morons

This video was very helpful. learned something very valuable in this video. I loved the trial and error. Also how they finally figured that such a simple thing such as direction of air flow could have such a crucial effect on how an engine runs.
You learned how not to tune an engine
porting an polishing is an art...and can DRASTICALLY increase engine performance if done correctly...better the airflow, better the power
Oh man i totally forgot Eric. The problem you were having could have been related to the spark plug gap.

So awesome finally getting to see the heart of #projectfairmont getting finished and tested, after what? Two, three years after getting the Fairmont and all the videos of getting it fixed up etc, the dream is getting closer to reality. Can't wait to finally see the finished product, Eric!
Yea, these things take time. Also, #FairmontProject.
+EricTheCarGuy #ProjectFairmont sounds like a black bag operation. lol
i like #ProjectFairmont but #FairmontProject it is lol
As i was sitting here watching you guys taking every possible stab at figuring out what was wrong as soon as i thought about that hat and how rugged it was and may not provide the smooth airflow into the carb...boom u guys figured it out...wish i knew earlier so i could be a keyboard warrior and say i knew it before all u guys :)
oh please!
I think that hat was designed for EFI applications like you'd find in a stock Fox body so it will fit under the stock hood.
I recently built a LS 2 based twin turbo engine using a Holley engine management system. Tuning was beyond easy. Through the Holley EFI, boost can be controlled with their boost controllers. This video is a reminder of just how far we've come. No trips out to swap jets, set timing, and boost parameters. It took just 3 hrs to tune, and most of that time was deciding how much power I wanted to make and where that power is centered. 5 levels of performance were saved into the computer's memory and can be recalled in just a moment via a laptop trackside. I have it set for 650/620 hp/tq street, and as I increase the suspension's capability, I'll use the other tunes (up to 1045 hp / 950 lb ft) for the strip.
All these armchair mechanics triggered by this video series. From the dyno to carb vs Efi, from the oil pan to the a/f ratio.
You'd think it was their money and project!
yeah they know shit about engines
It's just how it goes when you do an automotive TH-cam channel like this.
I'm really enjoying this series even though I was just a guy looking up normal car repairs! Thanks for the edutainment!
Scares me when stuff like this happens. Don't hurt a man's brand new engine :/ Lean. Just add more throttle? Hold at 16+:1 AFR..... Skeery. This is like part guessing when you have a problem with thte car instead of diagnosing and fixing. Just throw crap at it and see what happens? 41:05... smaaallll boost leak lol. Commenting as I go here.
I have never been to a dyno test before. I really enjoyed the time and effort you put in the testing. Wow talk about chasing ghosts.
fuel injectors it is.
Especially with how easy it is to tune a piggyback on a fox body EFI. Windsors are some of the easiest motors to tune.
limpkit2011 Nah, that's pansy talk!!!
Altair Ibn-La Ahad I'm sure he is saving that for more videos later.

Air is lazy, and resists itself going in a straight line, much less making a radical turn. The only thing that flat hat is good for is filter relocation for cool air intake/no boost as this experiment proved. A blow thru carby can be twitchy to setup [boosters and air bleeds need to see the same pressures on top], but this episode might help the injector fans too: velocity and wave effect/backpressure may tweak effective boost values seen in the ports differently along the rpm range. I'd like to see a dyno test with heads modified to chart flow or pressure seen in each intake runner on the heads to compare aftermarket manifold designs flat spots in certain rpm ranges on a typical v8 injected motor, but that may be more trouble than Eric would like to get into. [There's always cool looking stuff out there that doesn't actually make the grade]. Mainly - to compare front vs. rear cylinder performance VE at various engine speeds. I note alot of OEM manifolds always add extra intake runner length and seem to pay attention to minimum turn radius details to a point that seems silly to anyone who never turned a wrench or tuned anything.
Thanks for showing real world and not editing out all the crazy problems we can run into.
he was my teacher at unoh
Hope you kept your receipt
on a scale on 1-10 how good did of a teacher was he

amazing engine! thanks for all the videos eric ive been watching for years and i give u major credit man! SO many people complaining about how long everything is taking you can tell they never did a build before! great job man keep up the good work!
Thanks for that. You're right, to do this correctly takes time and a lot of work.
btw, love carbs, but modern times hey, injectors........ even more power then, nice figures now Eric!
MrBugsier5 gale banks firebird
You have more control with EFI granted, but you can make just as much, if not more power with a carb.
EricTheCarGuy yes EFI has a bit more control, but the reason I said gale banks Pontiac Firebird is cause it has a twin turbo big block Chevy and has a carburetor and he wanted to go 300 MPH, so power is still there with a carburetor
Yea, carburetors are just fine for making power. I think it's just that most people don't know how they work, or how to tune them is the reason why they don't like them. Hence the reason I asked Mr. Mailhot in the video if he thought tuning carburetors was difficult.
oldschool aint bad!
man this sound so nice, so beautiful
Amazing school glad to say im a past student.
that was an amazing video! That sound just makes me feel a little tingle inside lol I hope all is going well with it!
Do you have a boost referenced carb?
Sounds soo mean man, freaking wicked engine. Nice work and can't wait to see more.
"So I haven't broken 500 horsepower"
"Ooow but you will, you willl..."
Hahahaha Awesome!
Extending the fuel bowl vents with steel brake line will help the issue. The carb was the biggest issue. Boosting a carb is a challenge! It was a huge relief seeing it start acting better by the end.
HeadFlowInc yeah, boosting a carb I would've gone suck-through personally. That said, only carb I've boosted was a Strommy on a Red straight 6
The carb had nothing to do with it.
did you guys not watch the video? It wasn't the carb!
The carb vent tubes needed to be shortened approximately 3/8 inch to clear the carb top hat, not extended.
The carburetor was/is not the problem, it is the cheap, poorly designed chinese carb hat.
RedneckRectum I was pointing out an alternative is to extend and/or turn the bowl vents routed towards the hat inlet. As long as it's running good it all worked out.
