well more turns = less power, longer runtime. less turns = more power, shorter runtimes. more winds = more power etc. if your truck had a stock motor with less turns, yes, the p2k, though a great motor, will be the same if not slower. on the other hand, the p2k is a high quality motor, probably alot better than the cheap stocker, so the speed may be fairly close simply because of quality. p2k is a good motor for rc drifting...
