Nay, you would require a large outrunner for any kind of direct drive setup- Linc & Sike are the best guys to discuss that with. Running buggy wheels would be a no-no too, have to be MT sized rims, although 1/5 TC rims would be interesting- depends what the rules say about that kind of thing as some events are cracking down on using parts that arent designed for that specific class of vehcile (like TC wheels and a TC body on a Wheelieking for example...
).
Curious though:

A 51tooth Mod1 spur and a 25/26tooth pinion should be plenty to push in excess of 70mph, just dpends if the motor will foul the tranny or not. If it does, you can run a second motor mount spaced off the first with short posts, then flip the motor across so that it wont interfer with the tranny.
Kinda like this:
Not pretty, but it will allow for much taller gearing without tranny clearance issues.
