just a question here for you guys, how much of a difference is there between 5 psi of un-intercooled boost and 5 psi of chilled boost? I know there should be a difference, but I just want to know what I should expect in terms of hp gains. Thanks

 

Depending on the size/type of the IC you are going to see some margin of pressure loss. Here is just one example of the benifits of intercooling. This is an SOHC EG with the Apexi kit. It loses 1 PSI from the addition of the intercooler but you can see the results speak for themselves......
