I got less braking by now, so I dont think there's a efficiency decrease.
I forgot to tell in the first post, that I still have mounted a front one-way diff.
The track I'm racing at, is small and tight, it's mainly around 2 meters wide and approx. 90 meters long. It's also quite technical, so regular bypassing another car is difficult. for the most, one have to stay behind and stress the other driver. When he make a mistake, you got the chance to pass. The track layout can be seen here: http://www.hillrace.dk/intrack2.jpg
So with my driving skills, I found it hard to handle the extra acceleration, that the ligther drivetrain gave me. I went from 27 laps to 26, when I igthend the drivetrain. I'll have to do some practicing, and see what I can do now. When I get used to it, I think I'll try and switch the front one-way to a graphite ball diff. Eventually combined with a one-way pulley.
But still, I dont quite understand, why the car has a little less brake effetc, while off-throttle, compared to the heavier drive train.
