As Shirley implies, this sounds like a very bad idea, nor would it be simple to do. A bad idea because a front-wheel-drive is intrinsically directionally unstable (it has a tendency to swap ends when turning; worse at higher speeds and worse on a slippery surface). The reason that your F5 can mostly avoid doing this at 8 mph (already a high speed for a FWD) is because there's a module that senses this and backs off on the turn for you.
Difficult to do because at 24V you can only get "tot" RPM at 100% speed. Unless the speed has for some reason been turned to under 100% (not very likely), 8 MPH is all you can get without increasing voltage. If you wend to 36V, you indeed could get 12 MPH, BUT no standard wheelchair controller can handle 36V. That's why Burgerman, in order to build his BM3, went to using a Roboteq controller - and this was decidedly NOT an easy thing to do, nor was it really fully fine-tuned when he was sidelined by a pressure sore.
