Lets say the CEN mt does do 45. If it did go that fast it would need to be geared fairly high which would take all of the muscle away from it. Get a cheap OFNA buggy for about 250. The buggy will go faster, have tons of "muscle", handle better and be FAR less likely to break. Plus a buggy doesn't have a 2 speed tranny which in this case is a good thing. If you plan on making jumps out of plywood in the grass then a buggy isn't that great and a truck would be better. If you really want a truck then get an RC10 GT.
