I know it's debatable, but if you use typical rear wheel drivetrain loss of 18%, that's 640hp from the engine!?
These things are monsters from the factory and it seems very underrated by BMW.
Thanks Robert @ EAS for getting me in today! Looking forward to working together.
Very impressive dyno. Our project M5 dyno'ed at 550WHP
So yes, these are 640+ machines
