    DC motors seem to transfer the energy more quickly. That is why a lot of drag racers have been using them at the expense of the brushes, added weight and lower RPMs. I still have a DC motor in my...

    Adding a centrifugal clutch to the drag bike.

    Hello all!

    We are looking to knock off some time on our drag runs.
    I have always felt the Toque at Zero RPM is not really translating to the wheels when the motor is stationary in a AC system.

    I got the 1.7 Sec from the video.

    They said that they had set the clutch at 5000 rpm. That seems a bit high for a electric motor. I hope they are not using ICE logic for this application....
