I've seen 110 mph on mine on an icy road, 102 across the lake. 6-7% on every one consistently. 110 is pretty decent. My best running stocker would run 112-114 tops in perfect conditions Quote Link to comment Share on other sites More sharing options...

Big Crappie Posted February 5, 2021 Share Posted February 5, 2021 Do you change the power bands to compensate for higher boost and are there special power bands for turbo 4 stroke engines or can the 2 stroke power bands be used? Quote Link to comment Share on other sites More sharing options...
