intercooler sizing for supercharger

avioni · 03-28-2023, 06:30 PM

i have a topgun treadstone IC the first model(short one) if you will. at 14.5psi I was seeing 144F IAT at the top of 4th gear now at 16psi top of 4th i am seeing 167F IAT with an ambient of 75-80f.

I want to upgrade the intercooler and looking at options for the 370z. the thing is i still use the stillen plenum so the intercooler needs to have one input and one output only and all i see from soho,topgun ect... have two outputs and a blowoff port.

looking for options here. maybe experiences from others. thanks

Cheapest option is to seal the front end completely. Very time consuming, you can go to the track section. I have a thread on it. Do not buy treadstone, you want something like bell , Garrett Or C&R are all good state side options. 4.5 core. The 4.5 core around 12” high will solve your iat issues.
