Want to start a brushless speed demon.

GTP 2 converted to single speed (2 speeds and electrics = no good). I think the conversion gives you a center diff, lock that sucker up tight so you don't unload all of your power. After that a 2200KV MMM combo on 5-6s with proper gearing should push you to 80 without a hitch. Gear up some more and 100+ is possible but I think you should start off making runs around 60 MPH and work your way up from there so you can get a hang for the handling and get your car totally dialed in.

Electrics motors are definitely torque monsters, but that's not what they're all about. Basically your speed comes down to the overall reduction ratio and how many RPMs you're turning. Brushless motors have the torque to pull MUCH taller ratios than a nitro and can turn twice as many RPMs without a problem, so you're on the right track already just by ditching nitro for BL.
