Center Diff - 2.2 slipperential
additional - 1
Spur - 34
Pinion - 24
voltage - 24 6s lipo @ 4.00v
Kv - 2700 Neu 1515 1.5d
tire diameter - 5.75
Ballooning - 1.0
So who's willing to find out how much wind resistance there is on an e-revo @ 145mph:018:
I seriously doubt it will ever hit that speed, but it'd be really cool to try. Nevermind the ensueing explosion that'd occur if you wrecked:028:
Just a thought.

I see a couple of issues with the numbers you input that make it very unrealistic.
For one, the lipos will likely not hold 4.0V under load, more like 3.5-3.7V depending on which cells you use...maybe even less using such a high kv motor at 6S.
The ballooning is in terms of radius, not diameter. So if you had 7.75" tires due to ballooning, rest assured, you won't keep it straight enough to drive it fast.
