Rustler 8s/9918: gearing/cells?

[kulangflow]

Howdy!

I finally bought the 8s! Now I have a quick couple of questions:

(I've done a bunch of research on this site, but I haven't really figured out a definite answer to my exact situation, so here goes:)

1) For high speed runs, what's the hottest gearing (32P) and highest cell count I can use without blowing anything up? (I figured out that I'm pretty much limited to a 60T spur due to space limitations. Correct me if I'm wrong. Maybe I should switch back to 48P?)

2) Same question about gearing and cell count, only for bashing and long runtimes.

(Background info: I run GP3300 cells, and my Rustler is stock except for: MIP CVDs, RPM bearing carriers, UBEC, Swami Wheelie Bar, Road Hawg tires, M8 radio, and an aluminum idler gear.)

Thanks a ton for your help!
