But, there is an interesting question.
There are no ROAR rules affecting HV motors. I've heard that some guys are trying to cobble together some rules for 1/8th electric racing, but they will probably be wide open, anything goes.
I can check with Bob about the vehicle weights and the setups he used for his conversions We did this chart for winds/gears for the E-Maxx:

Here is the page for system/gearing suggestions for the various 1/8 Scale conversions:
