All that matters is the relative difference.
The E90 on this dyno was way lower as well. (I also don't see enough fans, etc) |

That was the first thing I was thinking too, where are the fans? This is going to start another dyno convo, it would be so cool if there was one type of dyno, hermitically sealed in a room where all conditions were the same all the time. Were seeing ranges of 370 to the wheels up to 420 to the wheels. Whatevs. Cars still amazing

306 whp for an E9x M? That is a very low result, even in comparison with the F8x at 380. Maybe the F8x not broken in.

So strange, 10hp apart per BMW, 70hp apart on this dyno.

The lowest S65 dyno that I have ever seen in my life that I could believe was 330 WHP... that would make the F80x at 406 WHP; far mooore believable but still on the lower end. This can't be a dynojet and if it is; what settings r they using?

Seems like a very low reading dyno, but having them both there provides a nice point of reference for the real horsepower difference between the two cars.

I'm definitely not an expert, but...
1) Assume E9X makes 414 HP at the flywheel 2) Assume proportionate drivetrain/dyno loss Loss = 1 - (306/414) = 26% F8X HP at the flywheel = 379/( 1 - Loss ) = 379/.74 = 513 HP Obviously I'm making some assumptions and 513 BHP seems ludicrously high, but WOW!

and I would say the apparent lack of fans you can also see how both cars struggle badly at redline compared to every other dyno I have seen. this is likely due to lack of proper airflow. both cars seem to be down about 10-12% power

Hmm, I'd like to understand more about the airflow restrictions (potential) or cooling restrictions.
NORMALLY an N/A motor is going to give a better dyno as IATs spike - i.e. a turbocharged motor is going to suffer more due to temp than an N/A motor. Nonetheless, I'd like to understand if there were airflow restrictions here... |
