So your saying 250-300hp is better than the countless guys making 400-500hp on stock 2.4l srt-4 motors? I'm good friends with Eric (erabbit23) and his car made a ton of power on a stock block, I can't exactly remember how much exactly but it was definitely in the upper 400-500hp range. Your comparison between your motor at xpsi vs. an srt motor at xpsi is irrelevant unless both turbos were the same, not to mention what kind of tune is on each car. 20psi on a 37r vs 20psi on a stock srt4 turbo are going to be quite a bit different in regards to horsepower numbers. I'm not trying to be a dick, just shedding some light because there is quite a bit of misinformation here.
