you will definitely need air to air if you have the turbo up front. Only reason I get away without it is because my turbo is in the back and I have the ottp h/e, dual pass, option b, phenolic spacer and meth injection.

Compounding the boost works a lot different then a by-pass setup.

Basically you can run less boost from the turbo, less boost from the SC and still make a lot of total boost. Less boost = less heat. But heat soak should be of concern.
I am not trying to talk anyone into doing it one way or another. I am just trying to provide enough info for people to make an informed decision.

So if I don't bypass I could in theory run the k04 compounded to hit my 400 hp mark? Just at an insane 28-30 psi? Tho at that point I would say I'll suck it up and deal with 325 hp or so, since I'm running a 10.5-1 compression 2.4 bottom end with a very restrictive 2.2 head, anything over 325 I'd just be asking for problems

Doesn't the problem with heat come from compressing air, correct? I would assume the higher the volume of air you compress the more heat that gets created. Even with less boost from the SC and TC isn't air still being compressed the same? If that is the case then since so much money is being spent wouldn't it be worth the extra cooling just to have piece of mind your AIT2 temps aren't getting too hot?
