Your best bet is to stick with a sprung hub on the C6X box...

I believe that rules this clutch out unless they have changed things...

Unsprug disks will not make the stock gear box happy.
You may be able to get away with it by playing with disk friction materials and a clutch delay valve. But the juice really isnt worth the squeeze with this one on a stock box IMO.

 

I have been through a few clutches tracking on a bumpy track.

My best experience has been with the competition clutch stage 2. Then I upgraded to a BWR gearbox and put in a Stage 3. Both are excellent for their intended usage, and no failures yet knock on wood.

 

I bought a new 725 Series: 16080-TD7R-2A for $600...too cheap to pass up IMO. I'm talking with Clutchmaster about disk options...

 

Looks like I can get organic material for one of the discs but there are no 'sprung' discs for their 7.25" clutches...

I guess it will be like the 12lb. triple disc Tilton I used for a couple of years on 993 racecar...after 2 years I hardly ever stalled it.

 

You're going to break third gear.....

 

I am going to a REV400 on a built motor so I will be visiting my trans internals pretty soon no matter which clutch I'm running...Black Watch Racing will be seeing it before too long no matter what.

 

How does that happen? Shock load?

 

Yes, going with organic on one disk will help but I am not confident that it will hold up to track use/abuse.
Guys manage to smoke transmissions with standard style clutches....

Clutch masters has an adjustable clutch delay valve. You may need to use one here. It will sacrifice clutch life to increase trans life.

All things considered, I do not think the benefits outweigh the compromises with this setup. A light weight flywheel and standard style clutch are going to get you most of the way there without really any drawbacks.

 

Thanks for the input. Clutchmaster is swapping discs to the organic linings, should help a bit with the engagement. I'll try the clutch with this set up and see how long everything holds up, what parts breaks first. With ~320RWHP and slicks, **** will fail so my question is not if, but when and what...
