Yes you are right no intercooler, that is the next upgrade. But intercooling isn't as effective as getting a custom grind cam . I had some internals swapped out, nothing major. The compression has not been lowered too much. I think it is 9.0:1 or something around there, I'd have to ask my mechanic for sure. Hopefully with the intercooler I might see 12psi.
