Budget Blow-Thru SBC Turbo kit! (Youtube 355 Update)

[@Bearded_Viking87]

Thank you for sharing, hoping this information will help my son and I. We built an engineer with almost exact same spec I used the 292 on 106lc grind delta ghost cam. But might have to change it for this project. We built it in honor of his battle with leukemia and he is about to hopefully take it on a pass or 2. But trying to get everything dialed. It was cool watching him put it all together.

Awesome video as always. I'll be taking my 3rd gen trans am I've been building using your vortec tips and tricks to midwest drags next year. I know I've said it before but without your videos I would have spent way more on my sbc build. Got a ford 9 inch on the way with 3.90 gears and a 200 shot nitrous kit to see what she'll do next spring. I ran a 8.6 1/8 mile on cheap street tires, weak fuel pump so couldn't run engine past 5000rpm lol, and 2.70 rear gears. I did get a holley blue fuel pump so I can get 1 last run at a 1/4 mile track and see what it can really do before it gets the upgrades.

[@michaelvoigt724]

Yes the distributor! 👍

[@evanarthur7535]

I read an article a while back that said dual plane manifolds don’t have good fuel distribution in a blow thru application. The engine was a SBF and they got good distribution using a single plane Weiand Xcelerator. They also tested a Victor Jr. and it wasn’t as good as the Weiand. David Vizard says the late model SBC roller blocks are good to 550 maybe 600 hp max. He uses 2 piece rear main seal older blocks for any build above 500hp.

[@cuttersperformance]

While in some cases a dual planes can have distribution issues with nitrous or boost, my personal experience I have had good luck with running dual planes with boost with blow thru efi. We have about a max hp with this efi of about 600 to 630 hp so we shall see how it goes with boost on the factory rods, hyper pistons, cast crank and a factory late model block. Maybe I should bring a mop? Haha

[@HotRodDave]

I have a zz3 crate engine from gm and have upgraded to trw flat top forged pistons and milled the heads to bring up compression and have sprayed a 250hp shot to it hundreds of times with no issues with the block. Should make 650+ on spray. Turbo is next hoping to make 750ish. Should be a good block test

[@KimiWallrus]

Engine Masters proved that a dual plane has better distribution and single planes with nitrous is a MYTH

Should be a beast with some boost, and hopefully easier to keep it happy with the EFI setup too.

Yeah it has' sorry about that. But yes afr enforcers style heads from DNA proformance. Will be interesting to see the results and I figured I can tune it easier and safer with the efi rather than a blow through carb. Hyper pistons and stock rods...gotta be careful

Wont the biggest determining factor be what fuel ? If its a 9/1 motor on pump 93 im thinking about 12Lbs at lowish timing should be ok with no knock?

[@antonherres7112]

Blow-thru is a carburator setup. It doesn't have anything to do with the inner cooler. You can have a inner cooler and a blow through setup. Blow-thru is when your turbo is pushing air thru the carb instead of the engine sucking the air thru. So the positive pressure in the carb is compensated for other wise you would just blow the fuel back into the bowl. With fuel injection wouldnt you just increase fuel pressure alone side boost or compensate with the fuel map, but a blow thru carb is built a bit different making it a "blow-thru"

[@cuttersperformance]

You actually get a "intercooling" effect with a blow thru carb or blow through throttle body injection. Much like meth injection, the fuel moving from the top of the intake to the cylinder head actually draws heat out of the intake charge thus dropping the IA. Some call this "chemically intercooling" and it works great with lower boost applications or works quite well if using e85.

[@antonherres7112]

@@cuttersperformance yes you get a cooling effect, but that's not why it's called blow thru, that doesn't even have anything to do with the name lol. And no you don't call it blow thru on fuel injection. It's only called blow thru on carbs with turbos because of the physics of how a carb works. BLOW-THRU HAS NOTHING TO DO WITH INNER COOLERS ( and confusing and combining it with differences of direct injection doesn't change that)

[@cuttersperformance]

@@antonherres7112 theres blow through carbs and you can have blow through efi (throttle body injection with a turbo or centrifugal blower) maybe its just a name but I know the manufacturers also call it blow thru efi. Could be a tomato - Tom-ato sort of situation

[@antonherres7112]

@@cuttersperformance if you want to call it that sure I guess, but it is for a specific reason it's called that. You could look into why they call the carbs that, like the physicals!! difference between the two types of carbs.

@@cuttersperformance If u have "weak" exhaust config but quick spooling turbo -U have quite small turbo that chokes engine at high rev. I suggest u to check backpressure before turbo and when backpressure=boost pressure its mean that u need bigger turbo if u want more boost.

Man. I am really new to turbo setups. I was planning on boosting my 355 carbed LT1 but I sort of gave up, it runs really good NA. About 9:1 , rings are gapped for it, forged pistons and rods, aeromotive bypass regulator with boost reference, running an HEI. The oil pan is tapped for the turbo return. I have a Summit 600 carb on there. I have NO clue what to do next. The car is getting painted now. How do I manage the timing??? Can I stay with HEI? Arent you supposed to retard timing under boost???? Should I go with a blow thru carb or EFI??

[@cuttersperformance]

Man actually pretty easy as you have already done the hard parts. The cheapest/easier way would be to run a blow through efi system like im running on this engine. They work great for lower boost setups with or without a intercooler. These systems easily control fuel and timing. You may need to find somone local or online remotely, if you dont have tuning experience to help safetly tune for power. Keep a eye out for a upcoming video where I show how to use a regualr TBI/TPI distributor with this efi system to control timing.

[@resistorstudios]

@@cuttersperformance so running the EFI is easier than a blow through carb? I will definitely stay tuned. By the way your vortec head videos helped me with my LT1 and a buddies engine as well. Two different machine shops did not think it was necessary to check /verify spring height or valve to retainer clearance. I almost lost an engine at the track but the broken spring held the valve high enough and i have +23 or so pistons so they have huge reliefs in them. Your videos helped me put it back together with the right parts and get it going properly.

[@cuttersperformance]

@@resistorstudios If you invest in a good blow through carb built by sad CSU or something they can be decent. But then youll need a MSD timing retard box to have some timing control.
