That's ^^^ the difference.

My AP1 dyno's closer to 300 WHP, but that's no mystery either.
what if you have a ap2 motor in an ap1? do i get half the power of an ap1 motor?

the intersection point would vary somewhat,
All dynos measure EITHER HP or TQ, but not both. They calculate one from the other, using the equation HP=(TQ*RPM)/5252 or TQ=(5252*HP)/RPM. Whether they start with TQ or HP, the two values MUST intersect at 5252, because they are just plugging numbers into one of the two equations.

It cannot be otherwise.

Hahaha, nah, it's the other way round. AP2 = 2*(AP1). Mathimatical certainty.

Stock AP2's do consistently dyno higher than stock AP1's. With an early AP1 like mine, you can pick up as much as 10 HP by switching to an MY02-03 ECU. Not really enough to worry about once you start boosting, but the power differences are quite real.

I really haven't got a clue why the TQ curve is so bumpy, but are you srue that the cat isn't clogged up?

I know its hideous!

WOW...I baselined 225.7/155 lbs tq on the same dyno!

I have an AP2 with a V2/testpipe.
Those are dynojet numbers.

Hey guys, well I recently had my car dynoed (obviously not in year 2000 like the sheet suggests). Only mod I had was a comptech CAI on an '03.

To me it looks like my TQ #'s are everywhere... Does this look right to you guys? could my comptech have moved around the torque curve like that? or is that normal?

Anyway what do you guys think?
Something seems off to me, most 02-03 AP1's we've done on DD dyno's hit somewhere in the 180hp mark. I think whoever set the dyno up did something wrong. Not to mention the torque curve is all whack.
