Guys let's do a group buy on Clutch Masters. I just opened my account last week.

Who is interested and what level? I'll supply pricing tomorrow.

I'm interested in being a part of the GB but, it would probably be for the stage 1.

What would the time frame be?

T_C_D · Post by **T_C_D** » Nov 09, 2009 7:22 PM

I have spoken to CM again today. I am personally going to try a material called Fiber Tough. It's holding capacity is 70% more than the organic with much better capacity to with stand the heat from slipping than kevlar or metallic.

I'm interested too but needs to hold 550tq
and still drivable. No pucked etc.

Yup, same here. Unfortunately clutches can be cheap, streetable and hold the power. You get to pick two.

Cheap + streetable + hold the power

1.7 @ 60ft for times and times.
I have used it on streets for about 3000km for now and no problems yet.

CNC machined M20 flywheel + m30 disk (with custom frictions) + audi S4 pressure plate.

pressure plate is mounted according to pressure test.

Does anybody know any SFI approved clutch setup for M20?
Local drag rules require SFI clutch, so I have to change it.

That's badass. 12.4 @ 112 is no joke!

Cheap too?

The key is he had a custom disc made. There is a lot of grey area there that makes that whole setup work. I suppose it could be cheap, but it also might not work as well as his particular setup.

For anything close or above 600ftlbs a Tilton 7.25" setup is the way to go. The problem is getting a flywheel that accepts this type of setup.

Jay Bee · Post by **Jay Bee** » Nov 10, 2009 1:13 PM

for the m30 you can use the s36b36 flywheel.

eBay sells Tilton setups fairly cheap, but the flywheel needs to be machined to accept it.

Wow your right, thanks for the heads up. They have some amazingly cheap deals, I have been seeing $1000+ for these setups, they are a quarter of this on the bay buy it now.

In regards to the Tilton setup, what needs to be done to the flywheel? Can you can use discs for any 10 spline 1 1/8" input shaft (ie- GM)? G&T, you are using this setup. Would you say the multiplate Tilton is streetable?

This was a stock M10 flywheel machined for a Tilton setup, it was also lightened quite a bit . I bought it like this and it was actually a triple disc but was missing a floater plate and disc, they were nla so I had the cover plate legs machined down to use it as a twin disc.
Also modified the stock clutch fork to make it work and extended the master cylinder rod. Took me about 6 times taking the tranny in and out to make it work.

So far I have replaced the disc's once, still available through tilton. The GM splines are a touch loose and not recommended by Tilton, BMW splines are smaller.
Streetable? well not really with the cintered metallic disc's, engagment is instant and abrupt, but if you slip it too much it greatly reduces the life on the disc's.
I have not checked but there might be an organic replacement disc's that would make it more streetable.

Actually the custom disc is like stock. Only the chopper content is a bit bigger in the frictions. The disc mod cost lika $40 or something.

Audi pressure plate is ~$150 here. (Stock, not SRE)

CNC machining the flywheel might be expensive

I have good friends that helped me

Well, as of this morning I have one of CM's "Fiber Tough" clutches coming from Todd. It should hold 450ish ft-lb of tq atw and still be streetable. I am excited and am looking forward to being able to turn up the wick. A full review will be forthcoming in a few weeks.

Russianblue · Post by **Russianblue** » Nov 23, 2009 12:53 PM

so what's the 'fiber tough' reference?

Brad D. · Post by **Brad D.** » Nov 23, 2009 2:05 PM

It's one of the materials that Clutchmasters makes their discs out of. It's supposed to be comparable to the Kevlar disc as far as holding ability and streetability but be a bit more tolerant to heat. FWIW, It appears that most of their Porsche offerings are made of it. I believe that Todd ran the same clutch on his car when it made 440wtq and ran a low 12 second 1/4 mile.

Scottinva · Post by **Scottinva** » Nov 23, 2009 2:18 PM

Then more videos with more boozt? Oh yes plz!

Brad D. · Post by **Brad D.** » Nov 23, 2009 2:40 PM

I'd like to have it all ready to go for a late December dyno day.

Scottinva · Post by **Scottinva** » Nov 23, 2009 2:50 PM

No dyno videos, I hate the noise lol.

I'm pretty sure that was the UUC organic. Whatever it was, it's still in the car and holding up reasonably well considering the abuse it took at the strip.

Hopefully Todd will chime in and confirm or correct me, but since I'm pretty sure thast CM made the clutches for UUC I would guess it's the same disc.

T_C_D · Post by **T_C_D** » Nov 23, 2009 8:32 PM

I believe what UUC calls the performance organic uses the fiber tough material.

Claimed 110% over stock.
So let's say you get a pretty good 200tq to the wheels
N/A. That's only 420tq

You would think "clutch masters" would have something that held a little more then that.

Well, Todd's car is a good indication that it'll take the abuse and hold.

Scottinva · Post by **Scottinva** » Nov 23, 2009 10:33 PM

I believe I looked up Brad's current clutch and found it to hold a maximum of 250torque, and he drives it daily without issues, at about 300torque if i'm correct. I guess they are being really safe with their calculations.

Brad D. · Post by **Brad D.** » Dec 10, 2009 6:36 PM

12/10/2009 - I received my Clutchmasters clutch yesterday from Todd and it looks awesome. It is a custom built unit that met all of the requirements - hold over 500ft-lb of torque as well as be streetable. It has a unique clutch disc that is unlike anything in their catalog. It uses a segmented Fiber Tough material on a full disc with a marcel spring and sprung hub. The PP is their modified Sachs unit. It also comes with a Sachs TO bearing, pilot bearing and alignment tool. I am excited to get it installed, I'm just waiting on another shipment of parts as well as trying to track down a spare single mass flywheel so I can have it machined and keep driving the car.
