just like it says would you guys even go 370 with this kit?
I know ryank has had good success with his combo but the single log oncenter housing and way the crossover is designed almost makes me wonder if more manageable boost could be had from a 346.
what do you guys think?

what size turbo? im in the process of doing a street kit with a T76, 6.0 truck heads, and a stock 346, i plan on doing a forged 346 later down the road, the guy i bought the kit off was putting roughly 700hp with that kit and turbo, that would plenty 'nuff for me

I have had 363, 383, and 388 cid with my turbocharger. Even though the smaller cid have more ultimate hp potential when max'ing out the turbo at high boost levels, I have never regretted going with more cid and I have run my best times at lower boost levels with the larger engines.

i would save the money, keep the smaller cubes, and make the same hp

big cubes is a good thing but the iron block adds weight to the nose and keeps underhood temps hotter.

tti street kit is not your typical T76, the exhaust housing is a on center and most T76 kits are tang housing's my guess is they did this to make it fit.

well from what i understand is this housing and the fact that all the exhaust gasses have to travel through one log manifold before it hits the turbo limit this kit.

when running to large of engine you can create a lot of exhaust back presure.

the most powerful tti street kit I know of is ryank's, 650 ish and he has a 370 with afr 225

I guess what Im wondering is if you guys think that the above mentioned would make it pointless to run big heads and bigger engine with this kit?

all opinions are welcomed
thanks

that is exactly what i think, yes

you can only fit so much air (horsepower) through the log.

engineermike

You can fit plenty through a log.

As for the cid question, the real question is, do you want max hp at a low boost level, or are you trying for max hp at a high boost level?

Keep the stock cubes with a log style TTI kit. You don't need alot of cubes when flowing through a on-center housing.

if anybody doesnt know both sides flow through it...not like there is a log header on each side and then the turbo.

does anyone know of someone who has maxxed this kit out on a 346?
I will be using my ported heads and my ls6 intake will this kit make 600whp @ 15 psi?

ah hell with it, I'll use my 346 save some$ and 90 lbs

engineermike

As long as it's a 3" log, it'll be fine up to 900 hp for sure, maybe 1000+.
