One of my friends back home has a holden monaro (this car is sold here as a pontiac GTO). He recently dropped a *lot* of money on it.
The shop he went to had an engine dyno as well as a chassis dyno, so he was able to get actual crank Hp as well as wheel Hp. I guess there really is no substitute for displacement ...
Crank power/torque:
Wheel power:
Kinda makes modding a wrx seem like a waste of time ...
