Here the results of the dyno run: 201hp, 186 tq at the wheel. The torque is pretty flat, at 2500 it's 155 and climb slowly to 175 at 4500 by 4900 it's at 185 where it remain around that value until 5400, after, it slowly goes down to finish at 160 at 6500.
Calculating 15% loss that give: 231 hp and 214 tq. With these value the power to weight ratio is 9.3.

That was hoping for a 200 run and he got it.

Results of my dyno runs yesterday on the Z-24.

Horespower = 136.8
Torque = 143.9

FYI, the guy at CAM said that 99.9% of all cars disengage the A/C at WOT. Mine is in the other 0.1%. I lose 9.8 HP and 15.8 lb-ft of torque with the A/C chillin'. :shock:

I guess my Honda is in that .1 %. I swear that at WOT that my A/C is still running? I can tell a difference when I turn off the A/C (or hit the "Turbo button" as I call it" at WOT. If that is what ~10 HP feels like, then maybe I need to chip my engine and get a new exhaust as my butt can tell the difference.

So no A/C or alternator defeat at WOT. Wow. What is the capacity of the alternator? Obviously 6hp is nothing to sneeze at.

Yeah, but I'll bet you are chillin' in the Chevy truck while it's towing your "real car". :wink:

No A/C in NC when it's 100+ degrees is insane! Ask Ryan about the drive in the CRX with it's 2-55 A/C unit.

Its not THAT bad. It probably would be more paletable if I could turn in a better performance at the events :cry:

I drove it to the event yesterday

But it was parked in the garage last week. I may be crazy, but I am not stupid.
