I'd like to see where you get those kind of weather differences, because the reality I lived in for about 10yrs of building and dynoing these things didn't show that, especially with stable near stock setups.Originally Posted by GTPpower
I get that you're going to continue reaching to find a way to disprove simple things that I explicitly hit the dyno to prove. There's nothing I can say or show you further to pull you out of that headspace, so I'm content having done what I've done, and had the success I did. My same GTP eventually hit 333.5whp with stock heads and non-I/C, using just an XP, GenV, 2.7", 42# inj, and dropped catback. The headers worked just as good as any other with similar specs. I even tested ported manifolds the same day as the stock mani dyno, and saw ~3-5whp gain on a setup going 13.3 with the PEM's at the time.
I don't know why I took the bait, but it's kept me entertained between yard work chores, so oh well.
