I recently went to a car show/race (C.A.R.R.S.S. Extreme nationals) an decided to do a dyno run. They had a Mustang dyno and asked the weight of the car. Not knowing I estimated at 3300-3400lbs. Anyway my run produced 170.55 hp at the wheels and (here's the weirdest part) 348 ft lbs of torque. The readout gave no engine speed and the run was made in 4th gear. This was with a paifully stock 00 SE 5spd. I was wondering if anyone has had their car dynoed on a Mustang and a Dynojet dyno, and if so what were the differences in the numbers, because I know that torque number is wrong.

 

I'm pretty sure Mustang dynos read higher than a dynojet but I could have that backwards. Sounds like they were reading axle torque also and not wheel torque (axle torque = 2 x wheel torque). Anyhow, I'd take the results like a grain of salt. Mustang dynos always seem to give very screwy readings. On another forum somebody else also recently posted a very screwy Mustang dyno result so maybe this was the same event.

 

Mustangs dyno ignition firing order is set at 90 or 180 degrees I think. It has to be 720 degrees for us (coil over plug).
