Just to clarify the differnce in numbers between a Mustang Dyno and a Dynapack, jet, or other similar machine. The conversion factor is about 10-12% to get at "typical" dyno numbers. Then calculating drive train loss at 15-18% you arrive at the crank HP.

Using our 205RWHP (mustang) you would arrive at 228-233 RWHP(dynojet). Then taking the 15-18% drivetrain loss you arrive at, using 230 RWHP, 261-270HP at the crank.

We stocked 176 HP on a dynojet, which would give the car an 18% DT loss from the factory.

The Mustang to Dynojet numbers I'm getting from the Dyno owner and tons of experience both with my cars and other people's cars on using a Mustang Dyno.

Just an example the car before us was an 02 Trans Am, heads, cam, full exhaust, 6 spd. Runs high 11's, layed down 372 RWHP.
