anyone ever used one? pros & cons? belt vs chain vs gear? which is more accurrate and last longer?
For a daily driver that for the most part stays below 4000 should be fine. For something like a drag car or road racer that stays in the upper RPM band, damage can occur very quickly, that's why most of the higher end engine builders use a belt drive. They also like it for it's adjustablity and easy to change when needed.7.5LITERFOX said:how high do you consider high rpm to do damage?
