I am Joe Strub - my sled 800cc Bikeman Viper - I have raced WSA Watercross for 5 years tried all kind of clutch kits using the stalker program to measure 20, 50, 100, 200, 300 foot MPH and E.T.'s with the best set up I hit 62mph and 5.6 sec on the water the Chris Iverson from performance engineering came out and we try the Hyper-Lite secondary the first run was 3mph faster and .2sec faster and by the end of the day we hit 71mph and the E.T. was 4.96 THATS A GAIN OF 9MPH AND .64 SECONDS
also we measure clutch and belt temps to see how efficient they are working before temps pri 196 deg F , belt 206 deg F, secondary 189 deg F - after pri 112 deg F , belt 136 deg F, secondary 106 deg F, keep in mind the outside air temp this day was 82 deg F. I have since gone to a softer compound belt and gained a little more, needless to say I was very happy we also tried the big wheels and gained from that aswell the week before.
