For any hating needs.....bmw calls for 300chp 300 cwtq.....Factor in your average drivetrain lose and your right in line.

It is also possible that because the reading is taken from the hub the losses are much less than with 60+ pounds of rim and tire eating horsepower.
Let's not forget if i have heavier wheels and wider tires the drive train losses will be more. In this instance his HP reading is with wheels having a weight of 0 pounds so is it really WHP worthy of comparison with other dyno results with wheels mounted?
This seems to be the most logical explanation. Assuming these numbers are at the flywheel it's still impressive and not out of line with other tuners even without an updated intercooler.
