    What you should do is find out how many CMFs you need to flow to make 600+hp and then find out if 2.5'' piping and throttle body can flow that many CFMs. That will answer your question.

    My Ep3 made 431whp at 15psi spinning of the dyno on 93 pump gas with stock PRB tb and manifold. Creeps to 19psi on the street but we tuned it for the creep so its all good. At that psi its around the 480-490whp range. Hope this helps.
