Hey Travis ,
Another potential for this would be amperage draw tests on your motor.No need for more motors and belts and calculations to figure horsepower and create a dyno. Just connect a meter and record and monitor amperage draw in various gear ratio arrangements, etc....using a variable resistance on the rollers?
Always love your creations bud
Are you sure you are focused at work everyday?
. Seems like your mind is elsewhere perhaps..... Lol
