I have been fiddling with the diesel/propane/NOS mixture which has seemed to work quite well if these figures are correct. When these power at the wheel figures are converted to flywheel figures my car is now making about 335-340ish bhp and 550-570lb torque ! Torque figure does seem quite high to me but will have to try out the new fuel mixture on another dyno to compare. If anyone has any comments good or bad please feel free to post them.
