Clutch interchangeability

[SZRacer]

Hi all,

I have a brand new and fairly expensive QuarterMaster triple plate V-drive clutch, which has a custom made adaptor plate to allow it to be fitted to a lightened Alfa Flywheel.

However, it is far too grabby and downright fierce for my light and low-power car.

I'm looking to replace it with a single plate cera-metallic unit.

Can anyone with experience tell me whether AP racing (or any other manufacturer for that matter)'s clutch units will fit a QuarterMaster bolt pattern?

Regards,

James

I assume it's a 7 1/4 inch or 184mm. If so yes they are all the same. I have the same clutch as you on my Jag and my mate has an AP clutch and the bolt holes are the same. Depending on what type of release bearing you have you will have to adjust for setup height though but you probably already know that.
I think the Quartermaster is around 900ft/lb so no wonder it's a bit grabby on an Alfa.
What plates were you using with this one?

Hi
if you go to the ap racing web site you can down load installation drawings of the clutches they make ( http://www.apracing.com/ ) . youre problem would probably be finger height . A triple sintered is about the same as a twin ceremetallic .
usually the clutches do get a lot less grabby once they wear in a bit

Thanks for all your help, guys. Much appreciated.

Had a chat with a very helpful chap from SuperClutch, and think they have something that will do the trick nicely, and fit my flywheel.

Anyone after a triple plate QuarterMaster clutch? I have one that has only done 0.5km (enough to know it was not suited to my car!)

Let me know.

James, I have a 4 paddles plate on one engine, its still a bit vicious, can you not get an AP organic plate and heavy duty cover that'll do the job ? 200lb/ft should do you ?

Thanks, Zeff

I think you're right, and that an organic faced 'rally' type plate should do me fine.

After all, torque-wise, my car couldn't pull your granny off a sailor (and I use the word 'your' in a rhetorical sense here)...
