I recently used Tribo for the first time. I used it in a 19 spec motor with extreme high silver brushes (trinity #4379) and there wehere flames coming out of the motor? For a few secs it wouldn't even spin around???
I normally use and will in future (after this incident) Zubak's SpeedJuice. I tested it on a dyno and the results are great with them! You can get them on www.speedjuice.com.
I've won a lot of races using them. They give you more power and more rpm and keep the wear on the comm low!
