i just changed my heel clicker wieghts around to try to get my rpms up from 8200 to 8500. i put 4.7 in the heel 3.4 in the middle and 4.0 in the tip and it seems to be less now like 7900 or 8000. i have the 40 10 heel clickers with red spring 15.6 rollers a bender helix which i am not sure what number but it is set at 90 degrees. i have a 1.25 ripsaw and geared down a tooth on the top gear. what do i need to do to get these darn rpms up. its very confusing. 
Not knowing the helix angles is a major crapshoot but it can be dialed in. Remove all mass from inner hole & try that. You will be close if not bang on. Probably only a minor tip & heel change needed to get rpm,s perfect.Your helix could be anything but giving out the rpm,s now is a major help to get sled dialed in.

i run the same clutch in my stock viper(also changed to a ripsaw) and have it at 8500. engagement is at about 4400. setup as followed.
red primary
4.0 used to be 4.8 in shoulder
3.4 in center
3.4 in tip
running 52/36 helix 60 degrees
stock rollers
with this setup i am beating f7s, sabercats, rx-1, rx-1 mountain, xc 700,renegade 800H.O. all in 1/8th mile drags.
just one thing? did you change to 15.6mm rollers. i would probably go back to stock rollers.
