HOT DAMN... Mr.brown truck came today and I got the pulley.So I took it down and installed the 1500 rpm spring,which went surprisingly well.After that I changed the rollers,the old ones were shot and I knew the heavier spring would probably need heavier rollers.Luckily in my box of parts that the torque spring came in I had a several sets of rollers to try.The 6.75 gram ones I tried first were the ticket,I also tried the 7's but went back.Just after intitial takeoff it almost immediately jumps to about 8700 rpm,which it pretty close to where I think I need to be anyway.For some reason my top speed increased,it's going way past pegged on the speedo.I'm not sure of the actual but it's got to be 50 mph or more,it's also getting somewhere around 11,000 down a hill,maybe more,I'm not really sure how far I can push a stock engine with this many miles.So now I'm thinking of a new clutch,A stage 6 is hopefully in my future sometime soon.
