I installed a 100 shot NX nitrous system on my 99 GT last weekend. I took it out today to have some fun. I got on it pretty good and I could smell my clutch burning up....felt like I was just reving it in neutral it was slipping so much. This was just for a few seconds....then I shut the nitrous off. It's fine for normal driving, but can't take the 100 shot. My car has 80,000 miles, and its the factory clutch. The car has the usual bolt ons and a 100 shot NX wet plate kit. What's a good cluth to go with? Will I need a new flywheel? If so, which one? Also, can this be done on jackstands or should I take it somewhere? How many hours is this job and how much is normal for labor? Is there a link to a step by step install procedure so I know whats required? Thanks.

 

There is a discussion about clutches in the general tech forum that you may want to read. you shouldn't need a new flywheel, and it is an easy procedure. If you start on Saturday, you can take your time, drink a few and still have it done in time to head to the local strip (after sobering up of course).

 

Just don't let it get so bad to where you do need a new flywheel. I did that on my focus and the bolts holding in the individual clutch plates scarred my flywheel....

But gave me an excuse to get an aluminum flywheel to get a boost in acceleration.

 

I posted this in the power adders section, but wanted more people too see, so posted here too.

damn that sucks i just waiting for my clutch to go after i get DRs

 

You don't need a new flywheel, however you will need to get the stock one resurfaced which is no big deal and only costs around $50-60. Napa and other places do this service, just call around for the best price on resurfacing the flywheel.

As for a clucth its like asking what is the best catback. Everyone is gonna tell you something different. I have a Spec Stage 2 and its ok. It holds all my power just fine, but its very grabby and does chatter like a ***** if you don't give it some rpms when you start off in first gear. Once I learned how to redrive my car and give it some more rpms and slip it a bit in first its very smooth. Otherwise its a very nice clutch and I like it alot.

But I am a bit more hardcore then most. But if you ask me can't go wrong with Centerforce,Spec,Ram,Zoom, and for a 100 shot I bet the Ford racing King cobra clutch would hold up well too.

I did my own install and took my time over the course of two days. Took just under 4 hours to pull the tranny out the first day. Then 2nd day took around another 4 to install the clutch,flywheel, and put the tranny and all the other things back on. Its not to bad a job and if you are mechanically inclined at all with the help of a freind or two to get the tranny down and out it can be done at home. A Hanyes or Chilton manual is a must for this.

 

I like my Hays Street/Strip kit. Not to heavy on the leg and I haven't been able to slip it yet. I would suggest to you to get the 11" kit if you're worried about slipping. Also, stick w/ the OEM TB.

As for flywheels, stock is fine, but if you go to a 11" clutch, you need a flywheel that works w/ that size. FRPP has billet steel ones for a good price.

Also, don't forget to pick up a clutch fork, pivot ball, and pilot/throwout bearings as the former two probably are worn and the latter two you might as well replace while you're down there.

As for time, set aside at least the entire weekend if you're doing it alone. The hardest part you'll have is removing the top two bellhousing bolts, the upper starter bolt, and pushing the trans back in. The rest is easy. For shops to do it, you're looking at $500 at the minimum.

 

What torque rating should I be looking at? Will a clutch rated at around 500TQ be good enough? I don't want anything nuts...this is for a driver(no track racing)...but I don't want something that won't hold either.

 

I just called a local mustang performance shop. The guy recommended a CenterForce Dual friction clutch. Are these any good? I looked up online and didn't see a torque handling spec for it. Anyways, he said around $800 for this clutch with install(if my flywheel is good). This seems pretty reasonable to me....what do you think?

 

I heard lots of good things about it and I almost got that myself.

 

You cant go wrong with a Center Force clutch

 

Those are great. If you like to have those kind of discs, McLeod and Ram both make kits using that kind of disc. Also, Hays does too but I'm not sure if it has a marcel, though you can check that out yourself. Just note that Centerforce works by creating clamping force using centripetal force while the others use stiffer springs to inceasee the clamping force.

 

Keep the stock flywheel and get it resurfaced. The stock flywheel will have more rotational inertia than an aluminum and you need the weight and mass for a good launch. 60' foot time might drop with an aluminum flywheel. It improves your acceleration a bit but I don't think its worthwhile for the price of the new flywheel and sacrifice you make in the launch.

Centerforce dual friction FTW. Feels almost like stock but holds the power. Mines been great.

Get a firewall adjuster for the clutch cable and use the OEM clutch cable, not an aftermarket cable.

 

Thanks for the info guys! I went down to that shop and talked to the owner. he was very cool and informative. I'm going with the centerforce clutch and re-surfacing of my flywheel. the whole deal is only $800 plus tax. Seems pretty reasonable to me. Gonna get done next Fri. I'll post how I like it.....after I break it in of course!

 

Sounds good man. Enjoy having to take it easy for a few hundred miles cause that part sucks!

 

Thanks Spike....I know! I'm gonna do a lot of unnecessary driving just to get the miles!
