The fuel consumption on the M21 is better.
The bottom end power of the Murnan 35+ is a bit better but the M21 match the 35+ through mid and top end power - or that is how it feels to me.
Can't tell you about lap times since both days were practice days with no timing.
Both the MM35+21, and M21 are great engines, and have lots of bottom end. Most people feel the M21 has more bottom than the 35+21. I like the new Picco 2069 pipe on the M21. It makes lots of power. The Werks 2058, and Novarossi 9886 are some more top pipes to use on the M21.
