clutching
hopefully im on the right board this time.what a great web site. i have a merc 340 fa. we did some drag races this last year and did real well.i want to improve the sled for next year, should i put a 38 degree helix on or leave the 30degree on. next i would like to put a comet 102 on. not familar with these. what spring and weights should i use for a5800 rpm engaugement. i have the smaller drive sprockets in, what would be the ideal top tooth and bottom tooth gears for a 500 ft run. the sled is fast but i think it can be faster
