This is to the rear wheels.

Whats the real number in crank HP and torque?

According to the guy at the dyno 225 HP
and 198 torque.
pretty low Inumbers I think.....Its meant to be 240 HP and 201 torque.

Conditionds: 4,400 ft elevation
Fuel 89 octane
Mileage of the Car 8,500

I will put a AWE ehaust
Evo intake and dyno again.
Then a Giac chip and Dyno again.

I hope for the elevation and type of fuel I ran this mods will help.

I guess it depends on what percentage he's calculating the estimated drivetrain loss as. I'm not sure how accurate this number is, but many people usually estimate roughly 15% drivetrain loss. If we go by this number, then your 195.62whp would equate to roughly ~230HP at the crank.

Maybe the 89 octance had a bit to contribute and perhaps retarted the timing slightly.

Just for reference, my 2002 2.7L dyno'd at 194.9whp and 175.2lb-ft torque. This was on 91 octane.

Can you post your dyno chart?

Yes, I believe 'RandallNeighbour' did a baseline with his 97 2.5L and put down 169.27whp and 147.91lb-ft torque.
