Ah, the car has 132 ft-lbs at the CRANK. At the wheels, after 15% drivetrain loss, that lowers it to 112 ft-lbs, so you're actually above average in torque (112 ft-lbs = 152 N-m). I don't understand the hp numbers, though. 170 is too high for whp, and 143 is waay too low. How were both dynos done? And what does CV stand for?
Dynos vary widely. This particular dyno might read very low. Its obviously not a Dynojet, so you can't compare directly to the dyno results we post here. And calculating horsepower back to the flywheel is a guess at best. You also might have a gasoline problem and are running into the knock sensor. You could try an OBD-II scan tool and see what your knock sensor activity looks like.
OK, figured it out. The measurement CV (Chevaux vapeur/steam horses) is equivalent to PS (metric hp). So he has 170wps, which translates into 167whp. Adding back the drivetrain loss (15%) ends up with 192 crank hp. So his car is fine. :thumbup: Maybe the difference in the curve is from the different tuning that gives it the extra 12hp.
