Never really thought about this.....

What would the correct gearing for my Ofna 9.5 buggy with Lehner 2800xl and 9918 on 12 cells be? I had it 12/52 the last time I drove it, and it had stupid amounts of power all through the rpm range, but seemed to get a bit hot. I'll admit, I never did a temp. check with a gauge (didn't bring it along), but was kind of wondering if I'm geared a bit low with that setup.......going up a tooth would be an easy way to check, right?

I'd kinda like to get this figured out before I completely have it back together, it's torn down because I'm trying to put a LX Comp diff in and it's taken a few more steps than I thought.
