I did some research on the LS side3 of the turbo thing and basically they were saying the ever popular 2.5" crossover is grossly oversized. I hope your 2.5" pipe is only the merged part and it is smaller before that

Do you think that the plastic intake will hold 6 psi?

Huh? Can you make some sense? That comment is confusing

My 2005 jeep grand Cherokee limited 5.7 liter had a plastic intake and they pushed 15 psi through that before it gave out

Silly question time... why a top mounted intercooler? Would not a front facing intercooler in front of the main radiator be more effective (tons of room in front of the rad and access to more airflow)? Also, you would have to have as a bare minimum a custom hood that permits the IC to face into the air and then have a path that lets the "heated" air escape from under the hood somehow, yes?


I am thinking that this makes for a potentially high/obvious hood, no?

Just your average Impala

Yeah I've been contemplating on just doing a front mount but I'm worried about having no access for tubing and having to cut into radiator support


I should be getting the manifolds made up on Sunday I'll take pics if I do

I was saying that on V8s 2.5" crossover is too big. For a V6 it would be monstrous. 2.5" might be an OK size for after the merge, but probably a bit oversized even there unless looking to push the motor hard. Compressed gases are just the compressed and don't take up as much volume so a smaller pipe is appropriate.
