That's NOT the RWHP or "Rear Wheel Horse Power"

That is the BHP or "Brake Horse Power"

Brake Horse Power is always less than rear wheel horse power due to driveline losses. Which vary on a number of factors. A rough estimate for a RWD car is ussually 15%.

Thus probably roughly 155 RWHP when it was new.

That is not RWHP, subtract about 20% and you'll be pretty close.

AHH NO you're wrong. Brake HP is at the Flywheel. and Rear Wheel HP is at the wheels. You'll always get a smaller reading at the wheels due to parasitic loses. Thank you drive through.

No Turbo II is going to hit those numbers as all of them have lots of miles or a much-neglected low mileage motor.

Just knock off 15% for a DynoJet.
Other dyno have different drivetrain loss multipliers.
