in my experience the fastest motor with a bit racer gear(3:43) is atcually the 3.8 you can punch out 11079 rpm (110,790 scale speed) Thats the speed of about 2 3.8's

. Now maybe since u say these babies are faster than a 3.8.......tie for me to open up my wallet.

BTW did your motor come with a white pinion gear also?
