The 997S has about 300 hp at the wheels. You have about a 15% loss in power throught the manual tranny to the wheels. Demand dyno of RWHP and not calculated crank HP as many shops simply use a higher drivetrain loss percentage to get the figures higher.

The hp figures are worked out using the same dynos as Porsche.The Hp is calculated by measering the resistance of the rollers to the road wheels after shut down at the end of the dyno run.
The dyno we use is a Maha which is the standard for the industry.why is it that no manufacture gives RWHP and by what you are saying the figures given by Porsche are wrong.
