The viper & TT40 properly set-up to race with an APC 9x6 prop spinning 17K is around 115~125mph. If it is just speed you want, an APC 9x6.5 pylon prop would be your best bet, and a few mph faster. If you plan on running the engine at the higher rpm's, you will need to replace the rear bearing to ensure it stays together. Most guys replace the standard ones with the Boca Bearing HP bearings. If you want to set up a motor PM me, and I'll send you some information on all you need to do.
