Darn you guys dont miss anything LOL, I was just being lazy and limited the max boost and guessed on pulleys just to quickly illustrate the power difference. In reality the boost will stop getting linear closer you get to the max impeller RPM but not quite that much. Intercooler and inlet restriction also takes some of the edge off the top end boost as well but here is what comes up using 10psi at 8.5:1 and 16psi at 8.5:1 @ 6500rpm with the proper blower speeds

You sure about that?

u put 16psi to a stock short block, it will blow. period.

what is ur goal? that would help everyone guide u in the right direction. compression wont much change ur power, its the boost that will. but typically, 8-10psi is the most people will put to their stock short blocks. u can squeeze more out of it, if u have a really good tune, an ic + meth + 112 or higher. but eventually, it will still blow
