Hi uhaulball,

That's why I posted this above:

HP ratings will be lower than numbers posted by BMW
- HP here is measured at the rear wheels (power to the ground)
- HP numbers from the factory are measured at the flywheel
- power loss is transmitted through the drivetrain from engine to the rear wheel (transmission, drive shaft, axle, etc.)
- bear in mind performance numbers are affected by ambient weather conditions as recorded toward the bottom of each dyno graph.
