Thanks for the shout out again. Always appreciate it. And so does the muscle car custom garage channel. Always love swinging by seeing what's on the dyno and more important when I could bring something as well. Thanks Steve. Thanks Kyle! You guys are great.
Growing up i wsh i had a uncle like you i lost my daddy at 4 so momm was daddy and she was a great one but she couldnt build a engine have talks about dude stuff this video hit my ❤ so i had to thank you and subscribe
I love this channel, before I was paralyzed I ran a 383 all forge parts, AFR heads, paxon blower, but in 03 we didn’t have as good tuning software as today’s computers do..had to sell after millions in medical bills, and a yr in the hospital..miss it bad, I came here from Cletus’s channel, during the 400k subscriber ask, and it was a great move, I was a paid subscriber for a while, but now I’ve got to watch $$$$ ..anyway this a good video..
Steve I know you’re a proud father. I’m 29 my sons 7 he loves your videos and we are only building surface drive boat motor and some pretty quick single cylinder mini bikes.
I love watching your videos. You offer mostly unfiltered content, warts and all, which I appreciate. Things go wrong, mistakes get made, we make choices and sometimes we don’t get the results we expect. You seem to have the ability to demonstrate how much trial and error goes into anything “high performance” in a way that resonates with me. Love watching you guys doing testing, adjusting, testing again, adjusting, rinse and repeat until you get to where you were intending on going. Very satisfying. Thanks.
It's why i tell people who got "LS ON THE BRAIN" that there is no need in it.... You see here a old school SBC built and boosted equally will make just as much... If you want the "LS" stuff for economy etc, you can get a computer system like Holley etc in the video and run LS electronic son a SBC.. I just wish Torqstorm made kits with factory SBC serpentine belt systems...
@@sstevocamaro Not for factory serpentine type setups... The 87up ones. Plenty of people have them.. Yet they don't make a supercharger for them.. Procharger and Vortech does, that's it to my knowledge for centrifugal types anyways.
@@ICONBADGTA cost vs power ratio. When you see that dart block alone costs about 8 grand. Thats why people hype LS’s so much. Most people don’t have the knowledge or the money to build a rival sbc vs an ls. I love them both, depends on the application for me really.
@@davidtappe5337 Oohhh come on!! Not cracking on ya, I’m mid fifties, 10 hr. Work 6 days a week. At least 3 hours in my shop after work. Enjoy your rest, brother. I’m gonna continue working!! I’ve got plans.
@@davidtappe5337I’m in maintenance department, at manufacturing company, Fabricated all day today,building an air vacuum for the laser department. I’ve got a real job also brother. Not an excuse to be on the couch. After work. Just saying!!
What a dream. Father and son side by side building and tuning engines. You have built an awesome life and business Steve, i wish nothing but the best for you and your family.
If you want to see the build of that LS, please check out the channel for part 1 and part 2 to get an idea. You don't have to spend the money in c&c ls3 heads. You can run stock ones to save money and a stock LS3 intake. And it will still make really good power.
I’ve had a ton of small blocks. Loved every one of them, especially the 300 hp 327 in my ‘63 Impala. Had it balanced and blueprinted - ran like a Swiss watch.
My Dad and I love SBC engines, great video Steve. Can't wait to to see the SBC brodex your building for us, just finished up with his Wing last weekend, tons of Down force tested over 500lbs at 50mph
I would be cool if the SBC in the car could grab outside air and having a ram effect. Maybe even a aluminum plate above the headers to even keep more heat off the supercharger. Thanks for the video!
Ole 383 been around for 30+ years or more, still kicking but, I have always wanted the 3.625 stroke 4.030 bore, with 6.0" rod, should do great, the 377 has been kicking but since the 70s, along with this 383, old school kicking arss, love it!
Please inform us on induction ducting. Fluid dynamics are neat! ❤ Thank you for all y'all do. The amount of knowledge inside every brain is amazingly wonderful to learn. As well, the comedy and love in your channel is so nice, and inviting.
Steve, get your head around it! Blowers DO NOT suck air in, pressure differential allows atmospheric pressure into the blower/ turbo. Carbs DO NOT suck air in, pressure differential causes atmospheric pressure to press into the carb and act on the fuel in the float bowl to push it through the jets. This is why ALL engines lose power as elevation increases. This is not because the engine sucks less, but because there is less pressure differential at altitude as atmospheric pressure decreases. Facing the blower/turbo forward causes ram air to increase the pressure differential. Cleaning up the air inlet allows atmospheric pressure to act more efficiently upon that inlet. Understand a vacuum does not exist, only a lack of atmospheric pressure. A flat tire on earth is inflated to 14.7 psi on the moon. When you understand this, you correctly know why intercooling and A/C works. Lower air pressure = higher oxygen density= more horsepower.
Love how some guy on the Internet is telling Steve how things work. Who's been building engines for a long time? Who owns a very successful high end engine building business? Where is your engine shop?
How does the pressure reach equilibrium without drawing in air from the higher pressure outside the charger? In your own words "Blowers DO NOT suck air in, pressure differential allows atmospheric pressure INTO the blower/ turbo." you realize your describing a sucking effect where the air is being "allowed into the blower" in the front of the intake outlet on the blower? The very act of the air being pulled into the blower is suction by definition Suction is "The production of a partial vacuum by the removal of air in order to force fluid into a vacant space". The blower is removing air in order to force more air aka suction...... also Air density increases as pressure increases, if what you said was true that it was the opposite than we could breathe better the closer we got to space or the higher in elevation one would go, we all know that isn't true, or at least hope we do....
Appreciate you taking the time to take us with you, where you start from and the simple approach to tuning. It’s know fun to make a giant number and then break it, reliable power is pyles more fun!
Steve I always appreciate the effort and time you put into making these videos and sharing all this information and sharing what you do and how you do it cheers Jack from Australia
Hi steve I am following you from Belgium ,Europe and a I am now minus validen at now with a wheelchair person butt i was before that busy like 30 years mechanic for trucks and heavy machinery and by hobby looking ad diesels to tickle them and I became at your site for turbo charging and yes man yo are for my as well a true man and speak really honest about these things thanks man yo are doing fantastic work 🎉🎉🎉🎉🎉
Very different builds. Budget LS with a 84mm Torqstorm vs. a high dollar Gen 1 SBC with a 94mm Procharger. Quite a bit of difference in cubic dollars. Still fun to see what they can do.
@@taptoretry7335 Not even close. LS still running stock crank, factory block, factory lifters, factory heads with a $1K CNC port job, probably factory rockers. ZERO chance that the cost to build these two engines is REMOTELY close to one another. I build engines. I'm well aware of the cost differences. The gen 1 probably has more in the block and heads than the whole gen 3 build.
@@BigMikesGarage the block maybe but not the heads so much. you dont need some trick kick ass head to do what theyre doing here. but yeah an aluminum block is pricey def more than any factory LS but its also making a bit more power and can be leaned on much harder
@@KingJT80 The Brodix heads on that gen 1 are $3K new. There are no factory GM gen 1 heads that flow anywhere near as good as a factory gen 3 head. I never said the gen 1 wasn't a nice, quality piece. My point was that they are comparing apples and oranges. A high dollar, high quality parts gen 1 build vs a budget built gen 3 engine. The gen 1 is certainly a more capable build.
@@bigboreracing356 I sold my LS7 in 2016. If you look at my profile at the very bottom is an old video of it. 441ci 13.5:1 Rex Hutchinson built E85 built TR6060. Made well over 600whp naturally aspirated and ran bottom 10s in the mid 130s on a drag radial. Had I been able to run that car on a Northeast track like Atco or MIR it would’ve ran in the high 9s. Had I been willing to cut the hood and run a Holley HiRam it would’ve made significantly more power. I never had a problem with a N/A SBC.
When you have a sharp edge on your inlet duct opening, the sharp edge makes your opening smaller due to the turbulence that sharp edge creates. Colder air is more dense, having more air molecules per volume, thus creating more reaction when ignited with fuel.
Old school tuning method when switch switch racecgas turn up the boost lean it out and add timing till it just melts the electrode....then back her down a touch.👍😂
I developed a dry sump SLC 310 ci short stroke twin turbo. I used GM splayed valve heads (NHRA), 7.<a href="#" class="seekto" data-time="1501">25:1</a> CR. It made 1450 bhp at the tires at 8200 rpm and 14 lbs cockpit adjustable boost. Nice hot air intake…
Great video fellas. The business is in good hands with Kyle. He's got a cool head. I really wish I could have you guys build me a SBC. I can't swing it but would if I could. 👍

I loathe serpentine belt driven blowers, the moment you go to pulley down the blower to make some boost you know upper RPM slippage is just around the corner. At least this kit has a well designed guide/tensioner setup to maximize the belt wrap around the blower pulley.
The videos that you make with scene changes are just great. Will this one be better. Will dad's 383 beat the LS. The suspense is good. Love all the tech talk re air fuel ratio and timing too. Thanks. Rex in NZ.
Take a look at the episodes I have on muscle car. Custom garage. I go through pricing and what it takes to build this combo. You always can just buy regular LS3 heads and save hundreds.
I've only owned 1 turbo car in my lifetime and keep considering building a second one. My Dad was a big nitrous guy... Never liked that much. Back in the 80's I had to rebuild his engine a LOT! Today, I have 2 old school 460's that pump out between 300 (stock) and 500 (slightly modified) and both are plenty good with me. Just picked up a V6 F150 that's pumping out 300HP.... more than I'll ever need out of that truck. Maybe some day, I'll add a sushi slicer to it, but not right now... thanks for the comparison!
The additional 2 psi of boost also added more parasitic loss and you have reduced the vacuum in front of the compressor wheel so reducing the parasitic loss on the charger as it would be easier to spin. I think it's a combined result of an extra 1psi of boost and less parasitic loss giving 55hp vs 2 psi of boost and more parasitic loss giving 50hp. It's more the air coming in from the side or behind the compressor hitting the air coming in straight and causing massive turbulance. The bell acts like a nice smooth on ramp on to a highway rather than just being a T junction with a highway.
Nice analogy with the highway entrance, it also allows denser air getting some cooler air from areas away from the header. Even with the header covered its still probably well above ambient in that area.
@<a href="#" class="seekto" data-time="2366">39:26</a>.... It`s cool to seen purple spot moving inside the map while you play with your timeline inside the second window. Advice : Have you considerate to plug a second monitor on your laptop and use in extend mode? Like this you can have both of your windows maximized instead to be overlapped. It's common trick for programmer... You run your program in one screen and the other side you can see your code.
At <a href="#" class="seekto" data-time="1114">18:34</a> when the belt smokes against the coolant hose did the tensioner adjust that much difference to maintain tension? To understand serpentine drive belt systems does require learning at least one more language.
Steve get a rubber elbow for the inlet size and aim it upwards and slips the over a piece of metal tube in the new inlet and then you’ll have the cool air. Plus way cheaper than header wrap
Steves spot on with inlet modifications for flow. My first job 50 years ago the orifice equation for mass flow = 0.668*Cd*A*sqrt(ro*deltaP) was a key. Without that bellmouth the effective flow area is significantly reduced to between 60 to 70% if I recall correctly. Look at static gas turbine engine tests at GE, they all have bellmouths.
Throwing a procharger on my sbc would make my (current) dream combo. Some day, I'll either swap the pistons out of mine and slap an F2 on it, or if I win the lotto, have SME build something ridiculous 🇺🇲✊️
Great video. I would love for you to do a video on class legal turbos. There are a couple of wild things happening in our local series and I'd love to see you prove out displacement vs class legal turbo and make it make sense!
Alot of people dont understand boost is mearly a measurement of restriction, bell = better flow. so not necessarily more boost but easier flow of air into an engine which means more power.
All of my buddy’s Always trash talk my sbc! But my gm604 has been so reliable and I beat the daylights out of it in my s10. I know 400 hp is garbage to real racing… but I’m working towards 1000
I think there's a opening here for a new video. Maybe you should somehow capture the air in a program that shows how that Bell makes a big difference visually speaking
My older Toyota with 250k on the clock is working to get to 85 (the speed limit on the toll road by my house) in a reasonable distance. Not having the money to replace the engine, that's the limit for me. The idiots going more than 100mph might be a better test of Steve's concept. And yes, there is alot of them on 130 south of Austin. NB - when the road first opened the wild pigs and deer were not expecting cars going that fast.. several cars hit pigs in excess of 100. 😮 Totaled the cars. Still happens from time to time with pigs and deer at night. Run stupid races, win stupid prizes.
F1A-94 likes to spin well over the max rating to make best power. The efficiency spot you are talking about is just starting to be tickled at 74k rpm. If you aren't going to overspin, an F1A-94 isn't a great blower choice, as they really want RPM. On serpentine setups allowing for a little belt slip, we pulley them for 80k-82k for max power. It'll make 1400whp+ through a manual LS on a hub dyno like yours. That's with a flex fuel friendly compression ratio. The 94 will live a good while at that rpm but definitely not as long as it will at 74k. Fine for anything that isn't constant rpm like a boat though. The P1-X, D1-X, F1A-94, and F1X all want to be spun hard. The older impeller designs not so much.
That's not just efficiency. You're not only increasing the boost you're changing the air density. That's why the horsepower levels change regardless of the boost level.
Steve, one axis, two axes. Axises is not a word. ;) Instead of breathing out of a staw, what about breathing out of a funnel? Air can be compressed, so putting a big radius inlet at the big end of a funnel where more cold and dense air exist might be a solution.
Higher octane fuel does NOT create more power than the lesser. Octane boos only makes the fuel more stabile, therefore necessitates either more compression &/or more timing advance to increase power potential of the higher octane fuel. Now, an increase in spark energy, say a plasma ignition system, will cause a larger, faster flame front on ignition, necessitating the retarding of timing with either fuel. But you're still only going to get so much power, as the fuel only has so much BTU of power available to use. The pull by only changing octane & a bit of timing proves my point at about 12 minute mark.
Next year build. What high revving, wide torque v8 engine would you put in Euro drifter? (internals and turbos) Have to be in 1500 to 2000hp range.Going to be in BMW f22/23 coupe chassis.
hey steve, could it be a tech tip video where you show the difference with radius inlet and no radius, maybe show it with some smoke or something? would be cool to see
@KingJT80 if you are a competent tuner or have a competent tuner, holding down 1200whp (manual or locked auto) on an LS is a non-issue. At that level, tuning or an unrelated mechanical failure is pretty much the only reason for it knocking a gasket out. People who have trouble are the ones piling too much power in at low RPM.
@@andrewwilliamson3513 or the lesser amount of head bolts. this is why people move to the different heads on LS for the clamp force. SBCs actually have a slight advantage here
if only there were giant hose clamps to hold the composite bell on the charger inlet. (edit. lol spoke too soon, shortly after clamp appears) wonder how a velocity stack and larger bell end would work. (not practical on vehicles though)
<a href="#" class="seekto" data-time="48">0:48</a> Anyone going to clock the fact that Steve was completely disrespectful to his cameraman at the beginning of the video?
What’s the big deal? Who cares? Sounds like camera man was late and they were giving him shit for it. Typical shop banter. You ought to hear some of the crap people say when joking around in other shops around the world.
At the highest end SBC gen 1/2>Any LS. Head clamping force is a real thing. One engine holds everything in place, the other constantly shits head gaskets pretty much every run. Wont see this on setups that are only pushing 20psi tho.
Maybe he needs to tell cleetus not to make full passes after changes, might help with all the stuff cleetus blows up left and right, lol..I’m going to miss the SMX on his channel..Steve just rocks the world with his motors.l
