You are right,, the Sachs is a great choice, which I have now BUT....
Like I said and many others that went through this also said,,, in the big picture do it once now and you will be set with not having future clutch issues..
Good Luck

 

Please PM me the price for the twin disk, so I'm making a good decision.

The $1,500 in labor is not an issue as I will be doing the change myself. I will say that I would probably put in a new flywheel in if I were paying $1,500 in labor.

Though I would question your statement about not changing the flywheel as "not the right way of doing it". If the flywheel is out of spec or I was getting a lot of backlash/noise, than I would change it. I would challenge that changing it simply because "I'm in there" isn't the right way. Most of these DMFW will easily last 2 clutch disks (assuming you're not doing a lot of launches and power shifts). Even after two clutch disks, they are typically not out of spec. They are on the worn side, but still within spec. I understand the fear of leaving a flywheel in for the life of a second clutch disk. Nobody wants to pull the trans again just to replace the flywheel, but modern parts are much better than the old stuff.

Of course my experience is with a 600hp Supra and 333hp M3, but I would hope the Porsche parts are at least as good. Heck my M3 has 160,000 miles in the stock flywheel and has several thousand roadcourse miles (though the M3 had less then half the torque).

John,

Are you having issues currently with the Sachs setup?

Your feedback is very valuable, since you are making power similar to my goal.

Steve no problems,,love it but it will get worn out eventually,,as most do if you drive hard..
Look at my signature and past threads...
As you know a Search is your friend with many opinions and info to digest.

 

I agree about the issue after you're having a slipping clutch. My clutch has only slipped 3 times. Twice on fast shift to 4th and once during a launch. It currently holds full throttle in all gear with no problem. It even holds fast shifts to 2nd and 3rd. I plan on changing, before it's a real problem.

Steve, your 996 makes more torque then both your previous cars. The dual mass flywheel starts to wobble and will give you a vibrating feel in your pedal, its a pull type clutch so when you step on the pedal it is applying force that tries to pull the flywheel apart. I did try to have the dm flywheel resurfaced... It did not work out so good.

 

I only slipped my ACT clutch twice and the FW came out looking really nasty. Now I am not sure if it was new when the ACT clutch went in but either way my car only had 23k on it when I got it so it was not a high mileage part.

 

Tim,

The Supra also has a pull type clutch. My Supra made 540whp and 510wtq. My 911 currently makes 525whp and 515wtq, so the torque is similar. I was running a smaller turbo on my Surpa, giving me a better torque curve (63mm inducer with a .67a/r exhaust).

My plan is to add injectors and water/meth injection, so I can up the boost some more. I also have a 91 octane tune currently, so I will get that changed when I add the injectors. With that done, you are correct, I will definitely be making more torque than the Supra was making. This is why the post is about 600+ wtq clutches.

I'm convinced the ERP Twin is the best option and the price is very competitive if you're replacing the flywheel.

The problem is if I'm going to replace the flywheel, I might as well wait until the clutch becomes an issue. I was looking at replacing the clutch before it had a chance to damage the flywheel. If I'm replacing the flywheel, than I should just wait.

This stuff would be much easier with an infinite supply of cash.

I'd wait if it is still good, but likely if you have slipped it several times it is getting pretty sad. If Carbon clutches price is good buy it and put it on the shelf till the end of summer and do it in the winter. Why take time out of the little summer we have if you do not have to.

 

I am new to the Pcar world but not new to performance and noticed the ERP isn't listed on the main subject but many people are swearing by it. Is it listed by another name? Sorry, Newb here.

 

I think my question was answered after reviewing the thread a bit further.

 

I expect to try out my Spec 2+ tonight for the first time. I'll keep you posted.

 

How did you clutch turn out... I am in a similar boat and want to make the right decision and $$ is a concern at the moment.

 

Dont Fit a spec clutch they are just not worth the hassle

I finally had mine removed and replaced with a Sachs.

I needed to replace the slave and the accumulator due to the damage caused by the stage 2+

The Sachs is amazing compared to the cheap option.
