The Indi dyno is an excellent piece of bench or pit equipment. Besides a dyno, it can be used as a motor break in variable voltage power supply, supply power to setup electronics in a car, or as a power source for a lathe.

sent a dyno to me for review. I used it for 3 weeks then lent it out to several of the guys at the track and have not seen it for a month!
