Hi all
i'm curious if someone else has had a clutch change with less than 25000miles.
Report your mileage.
thanks

Clutch Change...

If you dig through the old threads here, starting out in third gear on several occasions will get you a new clutch. Many owners changed to the Stillen clutch when it came out. Many with upgraded whipples and twin turbos also change to handle the extra torque.
Both the Stillen and SPEC clutches have a better feel and engagement than OEM from our experience. We use exclusively the SPEC clutches for the modified (HP) cars and have heard only good things about the Stillen clutch for OEM-like power levels. One nice feature of the SPEC clutch is that they have 4-5 clutches for the GT - you choose the one that matches the TQ capability of the car from mild to wild.
We've done numerous clutch installs and if you need any help/guidance give me a shout. There's a few tips that we can share to make the install easier.

Is that an estimated or measured figure? I only ask because I don't think we've seen the dyno curves for a "cam'd" GT here on the Forum (someone correct me if I am wrong). No doubt that you have the best idle in all of GT land, but it would be really interesting to see how the cams effect mid-range and high-end HP and TQ. Please consider to post these results if possible.

Measured; in fact on several different brand dynos
Ed has had his gal on the dyno for both testing and as a participant at general car events and the numbers of approximately 800 RWHP have resulted every time.
As for the power band; the cams affects the lowest RPM levels however once she is into her mid range through the higher RPMs she pulls like a freight train resulting in only smiles.
And yes; she sounds “Bad to D/A Bone”
Now back to the topic of this thread; I have installed many of the AP Racing clutches as offered by Stillen and they are a wonderful OEM replacement as well as a clutch very capable of handling the higher horsepower gals. For example Ed's has gone in excess of 25K mikes with his and it shows less that 50% wear.

Thanks for the testimonial Bill. As it has been mentioned, our stage 1 street clutch has been used in everything from showroom stock cars to high horsepower twin turbo cars. From what I've heard Mr. Sims knows how to hustle a car around a track so the fact that he is so happy with the performance of his clutch definitely makes me happy! I have provided clutches to Discovery Automotive, The GT Guys, Heffner Performance, American Racing Technology, and many many more, including companies that utilize the Ford GT transaxle in kit cars. AP Racing only rates the clutch to around 660 lb./ft torque however I have never had a customer complain about over powering the Stage 1 clutch. Same goes for the Stage 2 clutch but that is more of a race oriented system. While it would be my personal choice in a GT, it is too aggressive for the average owner.
In regards to the OP's question. We have replaced clutches in cars with 1,000 miles (usually cooked after a hard, accidental, third gear start) to cars with over 50,000 miles (I'm sure you can all guess who that is!) 25,000 miles on a stock clutch is probably pretty good.

As I said originally, we have only heard good things about the Stillen Clutch - on par with the typical high quality of Stillen products that we have experienced. The clutches that we have installed are in cars with "substantially" more torque than the 660 rating - hence our tendency to use clutches with specific specifications exceeding the use case. I would have NO hesitation of using a Stillen clutch in place of OEM where the owner was more than happy with OEM. In these scenarios - the Stillen always gets well deserved high marks.
Since Ed's car has been dyno'd several times, any problem to share the results? Sorry to ask if they are considered confidential. As for "pulling like a freight train", I have no doubts, but this same statement has been used numerous times to describe even a stock GT. I hope that you agree that (pre-4.0L) Whipple'd cars running more than 800 RWHP are extremely rare. It seems that the community might like to see where the power is distributed and how.

This is the one we have in the Joyride GT - installed after a production assistant on Battle of the Supercars REPEATEDLY tried to get the car rolling in 3rd gear... it looked like a burn out contest.
I absolutely LOVE the stage 2 from Stillen. It feels like that's how it should have been from the factory!
