If they are all doing mid 30's on grass/dirt does that mean they are geared correctly? I heard gearing correctly should yield 40mph on asphalt right? Any comments would be appreciated.

You need to gear down to keep the temps right in the grass. 110-120 are excellent temps in the grass, actually. I ran my Revo (with 3905 E-Maxx tranny) @ 22/62 on 4s lipo with the 1515 1.5D and it ran very well on dirt and onroad it was a bit mad. 17/68 is way undergeared for onroad performance.

For higher speed, you also need more voltage. 4s is good for 40-45 top speed, 6s should put you past 60.

EDIT: If you want to run the E-Maxx onroad, 24/58 should be OK with that motor but watch your temps.
