my ap1 back on the dyno with a 3 inch exhaust

Good job! I wonder if the SAE #'s would be much different from the STD #'s? Nonetheless this is awesome for an AP1, seems that lately the NA AP1 & AP2's are being uncorked...
You should definitely try the BC stage 2 cams on top of that... I doubt that you would be disappointed...

i have left it on std since the very beginning. i don't want to change it to sae now. i have been trying to keep things as consistent as i can. as far as cams go, i would like to try out a set but i cannot justify a set of cam gears costing almost as much as a set of aftermarket cams.
for now i will be continuing to mess with bolt on's to see how much power i can extract from a internally stock f20c.

by the way are there any benefits of running bigger injectors in my setup even though im not using e85?
i heard once from a tuner that ull get better performance when you can keep ur injectors below 85% duty
after doing my tune on pump gas im gonna do a retune for 102 octane to see what i can get outta it

I was surprised to discover a nice ~5 ft-lbs across the RPM range when I got my larger Deka injectors. However, I don't know whether that is due to reduced duty cycles, or just a better spray pattern. If I had it to do over again, I would probably spend a little more for Injector Dynamics or the ones Hondata offers, since the Deka injectors have a hard time with pulse widths small enough for a smooth idle.

Quick question - does the GM IAT sensor mount in the same position in the intake manifold or did you have to do something different, like drill a hole ahead of the throttle body?

it doesn't. you can add a bung and add it to the intake pipe which is preferred. the oem iat sensor will read very hot due to get the reading off the intake manifold. the stock iat would read in the 140+ range. with the gm iat sensor, the iat's are in the 100-110 at idle. once the car is cruising, the iat's come down to 89-90.

Seems like not many people know about this.
Brian, is the GM IAT in the plenum or did you add it to the intake? When I had my EMS in, my intake temp wouldn't drop below 100*; OEM IAT. My Prelude would usually drop to around 80* while cruising, but it had more "cooling" mods; thermal IM gasket, CAI.
