exedy twin disc

[turboevo06mr]

i was wondering what the life span is on an exedy twin disc clutch,mine has 7,000 miles on it and kicked the dust.It only has 4 track visits on it but was run hard.The reason im wondering my stocker lasted longer than it and had more track visits than the exedy.

Was it the HD, or SD?

[Warrtalon]

That's not typical for the Twin HD.

[turbolarry]

Rebuild??
Do you do a lot of street driving?

[turboevo06mr]

Its the twin HD.My clutch only slips when i get on it in 3 gear.Its at a shop right now.I had the trans pulled and its on the way to buschur for the stage 1 upgrade so I told them to check the clutch and they told me the flywheel and pressure plate are burnt up.I asked them if it was still able to be rebuild they told me it was to tore up to bad.They said for the kind of racing i do and thats drag racing thats not a good clutch to use. Its also my daily driver

[Warrtalon]

It is a great clutch for drag racing - not sure who would say otherwise.

[turboevo06mr]

whats the difference between the hd and sd?Also what is your opinion of the best clutch?

[JustDSM]

The "HD" has a pressure plate w/ a clamping force of 2920lbs versus the "SD"'s 2205.

alright thanks

Can you get us pics of the clutch? Also have them micrometer the friction pads of both discs, check the runout on the intermediate and top plate.

7K is very low to burn up a twin and from what I can tell you certainly aren't putting down near enough power to really push it's limits.

Were you having any engagement problems? If the discs/plates were warped you'd notice it in the pedal and when trying to shift.

Get us pics and numbers and I'm sure we can tell you better than your shop what condition your clutch is in.

(BTW I have the same clutch)

see i havent seen the clutch yet but they pulled it friday and i was at work when they called me and told me about the clutch. they brought my car back to my house on the tow truck and droped it off because they didnt have room for it while my trans is at buschur.But the funny thing is they sent all the parts back with the car expect for the disc and presure plate but the flywheel is still bolted up.I was thinking maybe they broke the pressure plate when they were trying to release the TOB.I will get the clutch monday and post pictures.

sometimes when i got on it i had problems with it grinding in 3 and 4th gear

whatever happened to this topic? I have this clutch also. I've had in on the car for prob 13,000 miles now and mine works like a champ. Been to the track on it bout 6 times. Prob 3-6 launches per night. Interesting read.

my guess is the shop messed it up.


Mine has about 7k and still engages like its brand new.

WHat I suspect the deal was was that the shop didn't realize how thin the friction material on the individual discs was to begin with and assumed it had low life left in it.
