Runner length in turbo manifolds It’s definitely an interesting topic and I’d always believed in long tubes for better power, as in more usable even n/a but also believed that they would be better suited for higher rpm or the longer length they were tuned being top end power oriented. I remember reading a paper years ago on runner length and formula’s to calculate rough length and I took from this that longer runner moved the torque band higher up but not sure if this was 4-2-1 or 4-1 merger or even 8-1,on the other hand for two stroke engines it makes complete sense to me as far as expansion chamber frequency tuning is concerned
Richard im going to be switching to rapid 3d's, 3d printed carbon fiber intake manifold that has shown promising gains on other vehicles, maybe something you want to look into andd test for your viewers, wish i could post a picture on here for you to see, save a lot of weight and no heat soak. My combo is a gen 4 6 liter with ported ls3 heads 232/242@.050 .615/.605 on a 112.5 lobe sep and a bullseye billet 92/96 turbo, holley efi and it will run on e98. Will be firing it for the first time in a couupke weeks here. Cheers from montana!
Hi Richard, Have you done any tests on long tube turbo exhaust manifolds vs short? I've seen photos of turbo race motors with long tubes but I've never really understood why more performance street cars don't do it. Is it just a matter of packaging?!
Dang late for the QnA What's you guys thoughts about a sbc350 long tub hookerheader to tie in to a 1967 camaro cast iron exhaust manifold that set up for a turbo from that factory all feeding a vs racing turbo to a 450 holley carburetor.

longer runners in the intake or longer primary tubes in the exhaust move power lower-short runners move it up
@Richard Holdener Drifts N' Lifts did interesting test tubular vs cast. ENGINE DYNO TEST: 1JZ-GTE CAST VS TUBULAR EXHAUST MANIFOLD

Bro, $2200 for 20ish hp. I wish i made your money.
@@johndelta00 i got in on the preorder so didnt pay that price. and that was 20hp on an NA motor not a boosted motor

I would love to see some tests on the svo ford turbo.

get all the boost to the motor and good things happen
Currently waiting on a set of Lexan windows for the project car. I bought them on black friday... they haven't shipped yet. 😒
Mine was a leaking roof.
Yes. I'm First.

I need help. Fitech EFI
remove fitech and replace with literally anything else. problem solved.
@@johndelta00 it needs to be reset but I'm not that kind of mechanic and know nothing about it.
