You have to remember that a rolling road (aka an engine brake) can only give you an at the wheel measurement and give you a best estimate at the flywheel power factoring a transmission loss. Hence why it is Brake Horse Power (deduced from an engine brake reading) not Horse Power (factual output).

I currently run a stage 1 T3 which is my limiting factor, I only run it at 10psi. My car makes 162 BHP at the flywheel but only 132 BHP at the wheel. The general figure people throw around is the flywheel figure.
