SCX's on a 38 Topgun
#12
prob about 75-100 hours on them and im not easy on anything. i like going fast, ran them for a season with the xr lowers and went with -2 sc lowers and it really woke the boat up. been running 5 blades for the past month with the ring cut off and seems to be fine, havent done a speed run with the 5 blades, but won the local shootout for 36-42 ft boats. full tanks and 6 people still runs over 90mph. i run 70-72 at 4k rpms and barely in boost if it doesnt sell, i may turn the 509s into 540s and do dual downshaft and cleavers, that should put me to 1175 ish per side. besides the whipples they have been the best upgrade i have done.
