Any one running a cat clutch on a indydan bottom end?

[hertzdonut21]

Looking for any one running a cat primary on there sled? Trying to get the clutching setup. indydan set up the shimming for the 115 and balanced. I put the set up that I was running in my polaris clutch. 68 mtx and a slp blue pink. the sled is not pulling any more. it will run rpms well above 8000 if i would let it. More weight? Less spring tension on the second # to lower rpms?

Looking for some ideas guys?
Thanks

clutching

you will need to switch over to a cat style weight
starting line would be what cat clutches a 900 for
if i remember right 69 gram weights and a yellow white spring
do you have the newer set screw style clutch?
dogmeat on here ran into the same deal

good luck

i believe it is the old style. it looks just like a p85 clutch. is dogmeat on the forum still?

Clutch

I'm running the tmIII with the cat clutch. I'm running a 10/70 weight shimed for a cat clutch & a almond primary spring, 160 260 secondary spring and it pulls hard all the way thru. I'm runningbetween 7400/7800 rpm at 9000/10000ft. Hope this helps.
