Hi Tech Driven clutch

I used the primary 911 response cap on a 700 MM and liked it. Working on a 98 SRX mountain sled. Bought the secondary add on with a 44 degree helix. Looking for set up data for mountain riding. Tried to order the primary cap but hi tech is out of stock. Just wondered if I'm heading in the right direction. Installed secondary roller and tested at 1800 feet. Seems OK.
 
with the ER secondary kit you could set the sled up with a stock secondary and then drop 4 drgrees on the helix in the ER and you'll be good
 
Thanks 800. I'll try that set up. I spoke to Hi Tech yesterday. I think the owner's name is Darrel. He claims that he has a really soft primary spring that needs 4 grams lighter primary weights. According to him, the package (ER secondary with Cutler black white spring, 911 cap and his primary spring) works great. I think its worth a try. Have you tried his set up?
