Re: Custom Gearbox is very loud
If you have a tacometer, measure output speed vs theoretical output speed. This can help estimate how much drag you have. If you are at 75% or lower free speed, you definitely have something too tight. If the gearbox turns very free, and free speed is high say 97% then you may have gear centers too far apart. There will also be a lot of lash compared to other gear boxes.
