Here's the link - was waiting for that. As expected, BMW continues to underrate these engines. Overall, the numbers are kind of a wash between the 2, but the n20 has a much nicer looking curve for torque and peak for hp.
Thoughts?

Very nice output from both engines.
As the article states, in actual driving you'r not going to notice the subtle waves that the dyno will display.
I am impressed with the BMW engines greater high rpm breathing capability.
The tests were run on 91 octane fuel.
It'll be interesting to see dyno's from 93 where available, just to see if either engine has tuning capable of utilizing the higher octane.
Caddies engine may be more sensitive to octane.
