Well, I seem to be a little late on this Binary thing, but I thought I'd post my experience.
IT'S FAST!!! (Or my driving just got a lot better
I got the standard, non dyno tuned version and did all the recommended cleaning, cutting, and shimming. Unfortunately, I WAS having problems with my lathe, and ended up putting a giant gash in the comm which required me cutting it down to .286 before running it for the first time.
I also had a set of used, almost dead Birdman biased brushes that I thought I'd give a shot so I threw them in - chipped, and very used with some new Trinity Red springs.
At first, I dropped 3 teeth on my pinion following some of the advice I'd read on this thread and it was a DOG!!!! Very, very, slow.
When I went back to the same pinion (35T) that I had been running on my Monster stock, the motor was VERY fast. Whereas before, I had not been able to turn a sub 15 second lap, now, I had several 14.7 - 14.9's with a couple 14.6 and 14.5's.
Now there's a good possibility my driving just improved, as well as a possiblity that I'm just REALLY working the Binary and significantly decreasing it's lifespan (I have no temp gun).
With that said, I'm a HUGE fan of this motor.
