To all you high horse power mudders,I cant get enough of your site. I have spent many hours looking throw the forum to try to find an answer to my question. I have a 2008 Renegade 800X that I use to Dune and sand drag in Nevada at Sand Mountain. The Renegade was dynoed at 58.7 Horsepower (notstock) to the rear wheels. The problem is I run the hill at 6800 to 7200 RPMs and at speeds at around 50 miles per hour. My max torque and power are at 5650 RPMS and around 33 miles per hour on the Dyno. I run three stock steel weights and three Dalton Weights with no rivits and I would like to get the power up to where my Higher RPMS are, or do I need to Clutch to get more speed to get back down to my 5650 RPMS. I would like to gain some up hill speed butI dont have a clue as to where to go. I was able to find 2ea 650 Helix and am going to see if it helps. Any ideas.
