Cooling the clutch

So, heat kills these things..

Has anyone pondering how one might cool it? What about venting CO2 or something into the bell housing?

Wondering if you could get away with a more aggressive (6 puck, higher pressure plate) single disk vs a double if you could keep it cool when slipping the crap outa it.
 
on our pro mod car, we simply pull the cover on the housing and use a fan to cool the clutch between runs.

When we drag raced quads, we used a pump to circulate iced coolant back through the transmission and engine, replacing the hot coolant.

With a dry clutch like we have in our trucks, any method used to cool the clutch during a run would have to be air/gas.
 
Is it worth it? Does anything see any advantage to cooling a clutch during a run?

I've tried a few 3rd gear launches the other night and I wonder if keeping it cool would not only allow the clutch to last longer, but hold better and faster when your spinning 2500-3000rpm or so on your launch.

Rather interesting doing a 2500rpm launch, pulled down to 2000 and soon as the clutch engaged fully at 2000 the HTT64 lit and I was gone. I think I wasted like 10 feet to get it to lit? guessing.

what kind of safety and regulation issues can anyone think off?

IDK about the question above, but I'd think that with all the 6 speed problems you've had, you'd be looking to do an auto swap anyway. If I had it all to do over again, I'd go with a built auto over my 6 speed.

I have yet to launch my 5spd with the SB dual disk, but I think its a good idea. I dont know anything about the question though. Sorry.
 
But if you started cooling it before it got hot...

I follow you Jason, just not real sure how to get there...
 
i think a compressed gas would not be cost effective, and would be a PITA changing bottles etc.

I think something like bellhousing mods to accept some small fans (like those in a computer case) to be mounted that can pull heat out.

or maybe just a duct/scoop underneath (kinda like brake ducts on a road race car) that can ram some fresh air up into the bellhousing with a vent on top to push the heat out.
 
seems like it would be the same PITA of using NOS changing bottle jets etc. I don't see it being a problem with cost either, and I don't think he's talking about freezing the damn thing, but if you were to plumb in a cooling spray/mist during each run, I think that would help out for sure with longevity and any heat issues or carnage. I like the idea it wouldn't hurt to try it
 
Unless a spinning clutch can create air flow, I don't think it's necessary or enough to cut ducts. Computer fans, maybe

durning a drag race launch, and the entire sled pull would seem logical to me as conditions to run the cooler
