1/8 Diffs and Slipperential Gearing?

If you were to use the buggy diffs (43/13) as opposed to the truggy diffs (43/10), you would have a gear ratio closer to what you are looking for.

With the Slipperential (44/20), buggy diffs (43/13), 36/20 spur/pinion, 6" tall tires (to account for ballooning), and 35,000 RPM, you'd be looking at ~47mph. If you were to factor in 5.5" tall tires that won't balloon, you're still at ~43mph. Dropping down to 30,000 RPM with 5.5" tires would give ~37mph, which in many cases is a good top speed (might even be too fast for some tracks). So it looks like gearing wouldn't be too difficult.

I was already assuming the buggy 43/13 Buggy diffs. :002: The 43/10 never even entered into the equasion.

Yea, I went through the math, and it should easily be more than fast enough for the track. However I would like to be able to gear it for some light bashing and speed runs also. I do take the revo to the track, but its far from a dedicated track machine for me. Im easily getting 50mph from my setup now and would like to keep it if I can. I'm runnning 5s ~ 50mph for bashing, 4s ~ 40 mph for the track, and 3s ~ 30mph for the small indoor track.

Ive already got the electronincs and motor. This is going to be a retrofit to replace the diffs and transmision so I'm kinda locked in using the Quark 125 and the Neu 1512/2.5D(2000kv) on 5s lipo.
