As far as dyno and 1/4 mile times, I haven't done those yet. At 4 psi, it gets really, really, really old real fast. I tell you one thing, I surprised some mildly modded GS-T's. Hey TealTalon, stop teasing me with that FMIC man I can't wait to put this sidemount on, a small IC is better than no IC. My air intake temps was hot as balls, me and a friend of mine datalogged it, it was 185 degrees. There goes all my power right there.
