I've tried more converters in the last 2 years then most do in 10 years
the super 8 9" behind my 582 is as fast and mph's more then the 8" b&m that everyone loves and claims is bad fast.
I've ran sprag and spragless stuff the spragless stuff is always as fast as the sprag stuff .. same brand converters and different brand converters.
My thoughts slow 60ft is what I want, but I want it to haul rear from then on, and I seem to have found that sweet spot. My b&m will whip my TSI to the 60ft by 5 hundreths but yet will not out run it down track et or mph wise.
