I'm just curious what peoples opinions are on acceptable boost pressure drop for an intercooler setup. What are your experiences post intercooler install? Basically I'm just curious what is an acceptable pressure drop post intercooler install running stock boost, aswell as at increased boost levels. I have about a 1psi pressure drop at stock boost, so it's running at 5psi-ish which I'm told by a friend is too much for such a low level of boost. I'm wondering if I have a boost leak somewhere or if something else is up or if my friend is full of crap lol I always thought that 1-2psi pressure drop at any boost level was about normal?

Can someone tell me why there is a pressure drop? Fluid dynamics says that the system will just fill up with compressed air till it reaches the pressure defined by the wastgate. Is it the pressure change caused by the contracting of the air as it cools, combined with the restriction of the air passing through the fins that causes the drop, since the wastegate reference is at the turbo outlet?
300zxt, how are you measuring the drop, by plumbing a boost gauge before and after the intercooler and comparing the diference? When i installed my IC, i noticed miniscule change to my boost pressure (like

that's exactly why there's a pressure drop. The solution is obviously to reference the boost level behind the intercoolerAttached Files85 Z31 6.0 LSX turbo 766whp/792wtq
