I've been using boosted 10.5's for a couple of years now in 2 and 4wd. With enough boost it can hang with the 6.5's on the straights and has the advantage that I can reduce the boost for tight tracks and slippery conditions. In effect it can be several motors in one.
However its not perfect. A boosted motor lacks the low end punch of a hotter wind - I actually prefer this most of the time but it can be an issue when you approach a jump at low speed. Battery use is higher than for conventional setups which is no surprise as that energy is lost as heat. Things run bit hotter than normal, but not excessive. However motor life is certainly less.
