Speed update!
I just ran 7 passes by a 100ft section of road to calculate top speed and after eliminating the fastest and slowest time my top speed is........
44.2mph with a standard deviation of 1.7.

here are the detail
tires: worn out dirtpaws
gearing: 10t thunder tiger (e-raptor) pinion & 46t sur
motor: Novak HV4.5 w/ 5mm shaft
batteries:2x Maxamps 2s 10,000mAh lipo

In all I took about 10-15 runs, messed up the stopwatch on a few, forgot how to drive for a few ect. In the end, the motor was only slightly warm, the esc and batteries were room temp.
Sunday I am taking it to the track to find out how long it can last without thermaling (and to see how badly I drive)
