I've heard approximately 20% of the power from the engine to the rear wheels is lost to the drivetrain. Based on MWERKS numbers and 20% loss, the 135i puts out 350hp and 369 ft-lbs at the flywheel.
350/369 is a stretch; but I wouldn't be suprised if 300/300 is underrated considering the car does 0-60 in 4.8 and the 1/4 mi in 13.3. |
This is not really news, for it has been known for several years that the N54 produces
about 320hp. Secondly, it has also been known that the tranny loss is not static but variable based on RPM and does not exceed 13.5%
Again, Dinan has done extensive bench testing & research on this engine and all the data can be seen on their web-site. There is/was no need for speculation.
