Hi Joe

I too like you have proved to myself how valuable testing is with keeping detailed notes is. I am going to ask your opinion of this clutch setup using a 454 rotary rave valve engine with a 10,200 max hp. I have not raced in some time but remember my set up. I started out at 92mpm in 700' and ended up with 102mph at 700'. It was a huge gain and it was all done by getting my 10,200 rpms {dyno sheet max hp.} by using 10MR series polaris weights ground on the side to 39.1gr in primary clutch {quickchange 102C} after that I fine tuned the driven with a 50-75 spring in a polaris driven with those expensive cam shoes tri city performance had{15 bucks apiece no longer available but I still have 2 sets} with 23# of preload and a compound radius helix at 46/40 from hotseat performance. I was engaging at around 5500 and it would not get a good holeshot. Do I start at 52/40 and increase enggagement with a notch?
