I have to agree jay the non intercooler setup with snow injection is a good option and less plumbing, less potential pumping loss, and less potential for leaks. Plus 5 psi is a huge gain, many people have no idea how much of a gain it is.
We know that 6 PSI pretty much doubled the power output on a 100k mile junkyard smogger engine, which was 100% factory assembled, never opened.
