i am facing a problem with an installed s2 evolution motor on my firebird. i am running the 30k rpm motor on a 9/24 gear ratio setup. but when i push throttle, i hear a high pitched whine (same thing at reverse). when i put it down on ground it reverses quite slowly. i think its a problem with how i installed the motor, but need some help

Try what Cowboy said, if that still doesn't help, try lubing the bushings of your motor.

Re: s2 motor whine

well, depending on which incorrect installation it either has slipping gears or binding gears.

1.Check to see if all the appropriate parts are in place(pinion/spur/motor spacer)
2.Check for new found friction in the AWD shaft(if you have one)
3.Test motor spinning free from motor mount(maybe the motor has issues)

I don't know if this helps, but it is important to diagnose/troubleshoot your issue with these items. :wink:
