[No Groc Getter]

Let me try again.

Lets take my stock 93 LX coupe with a T-5 (205 hp) and bolt on a nice new procharger P1SC. I run down to the chasis dyno and turn (305 hp at the wheels). To convert to flywheel HP using the 20% conversion would mean that the same T-5 drivetrain is soaking up 61hp instead of 41hp with the only change being the new blower.

Taking it one step further. Lets say I add heads, Intake, exhaust and a cam. On this visit to the dyno I turn 405 at the wheel while still using the same T-5. Using the same 20% percent conversion means that the same drivetrain is now a 81 hp drain.

It is true that there is a parasitic loss through the drivetrain. I just don't think that it increases with horsepower. I think it stays a constant number as long as the drivetrain is unaltered.

I hope this makes more sense than my original post.
