just an approximation, and the bhp isn't the same and sae crank hp, also the mustag dyno's vary from each other as well, the larger ones seem to read lower, also strapping onto the machine can cause your results to vary, if your suspension is compressed on the rollers you've added weight and drag, and cv shafts comepared to earlier u-jointed halfshafts and one piece driveshafts compared to multiple pieces, there is no one true measure that fits all drivetrains, all are different and require different amouts of power to turn them
and i wouldn't hang around with supra owners if you paid me
