Help with hyper 7, 9xl gearing

First off, thanks for the great pics of how the cells are mounted in the buggy. That may be enough to make be want to go to A123 cells!

Good guess on the speed. I'd say you are in the 35 - 37 mph range. 13T will get you into 40 mph. Even with that gearing, you are only running 29% overdrive. I say "only" because I run my 10L at 33% overdrive with no problems. I'd say you could even push that to a 14T pinion if you wanted, with that XL can you have.
