Well, if I enter values, I get ~32mph. That's with Revo diffs, 2nd gear (std ratio) tranny, 40T spur, 15T pinion, and 5.65" for the tire size.

If using the 2 speed tranny, you can get more aggressive on the spur/pinion (like 36/16) since 1st gear will give you the grunt. Also, for 4s, I would go with a 1512 2d instead, especially since you're keeping the 2 speed (but that motor will easily work with 2nd gear only).
