i use milidons gear drive in all my race engines,they can be sometime a pain to set up,but i like them,they say they pull hp,but all depends,they whine a little.dont use a floating one,only ones fit behind a stock cover is floating,those are junk
I have never used one, but I`ve heard a few NHRA superstock racers say they DO transfer LOT OF HARMONICS. A very well known factory backed chrysler racer told me the same thing.
(years ago ) These are people that take it to the limit every time their engine is started tho. ???????
