rear wheel versus flywheek horse power

Does anyone have accurate data betwen dyno readings of flywheel and rear wheel horsepower on the same engine?

The only figure I have found is that on a RX-7 5 speed the loss of power to the wheels is 17%. This implies 83rwHp on a stock 12a. I have not been able to source this data.

I read somewhere that the factory horsepower was rear-wheel dyno tested! 101hp.

no way.. there's no way that the FB did 101 at the rear wheels stock. My '92 Civic EX beat my friend's '85 RX-7 GS and his car is hundreds of pounds lighter. If he had 101 at the wheels, he'd be pushing probably 130 at the flywheel. I'm pretty sure it's flywheel horsepower.

A completely bone stock GSL-SE will test out at 101 hp to the rear wheels. I tested one side by side with my own lightly modded SE (before turbo).

Here's a dyno chart for a GSL-SE with a RB dual exhaust, stuck 6PI actuators, e-fan and no emissions.
