sorry, I buggered that up. double that BMEP figure = 178.75psi at max power which is very good for a 2v engine at those rpm (Its BMEP would be higher at the peak torque rpm)

relationship between flywheel and road wheel bhp is dependant on the driveline. fwd cars lose less in the driveline than rwd due to the shorter lighter driveline, and not having to translate the torque.

It depends on the weight of the driveline components and the mechanical efficiency of those components. friction of course increases exponentially with speed, as do side loadings of helical gearsets. In general terms, a percentage figure gives a good approximation of drivetrain losses. 4cyl rwd cars tend to loose in the order of 20-25% in the driveline, and I'd guess this sport sedan had straight cut gears and was built light, so we'll go with 20% loss = 130ish
