What kind of lifespan do you get under normal conditions (ie a few runs down the drag strip per year and a few track days but 98% daily driver).

 

The JWT will fall apart the aggressive use of 625whp.

I would say 450whp is a better realistic target for that clutch...even then...there are better options, that will last longer, and suffer more abuse before failing.

 

i thought clutches were rated at the flywheel.

 

Most are "rated: at the flywheel. We are talking real world.

 

if my clutch is going does that mean i need a new clutch and flywheel or just a clutch?

 

Most of the time you will have to replace your flywheel too. The oem one is a dual mass unit and it is hard to find a place to resurface it. 99% of the places I spoke to said you need to replace it. Plus the oem one is big $ retail is around $1300.

 

well if my clutch is slipping then I suppose I would need a new flywheel as well.....

Any recommendations?

 

Not always the case Mr Sharif

On our track car and severall other customers cars we have had great success with the JWT clutches. We have seen them hold over 600 ft lb, tq. for well over 2 years and 20K miles with constant abuse.

Although these clutches are rated for 1200KG. of clamping force, that is a very conservative rating.

 

Don't get me started on this board too, Mr. Bush.

Clamping force is an absolute measured value. It is not something that can be overated or underated. Put another way, you can have two clutches with identical clamping force, but one could hold 400ft/lbs, and another with 700 ft/lbs, all with the same clamping force. The trq holding capacity is the measure to look at.

Your claims are so far out of left field, I wish I had more time to debate this with you.

 

EDIT, nevermind I caught myself and decided to change my mind about what I wrote. I STILL refuse to stoop to your level, no matter how tough the temptation. I will bite my tongue for now.

 

+10000 This is the best clutch/flywheel I have ever used

 

When we are responsible for how our customer's cars leave the shop, we don't guess, take chances, or hope that something will hold up. Many of our customers fly in, and DRIVE their car home, sometimes 12 hours. No trailer for backup, no nothing. And knock on wood, not one person has called us with a problem on the way home.

When a customer trusts us with a large scope project, I dont have the luxury of speculating on what might work, or what works 90% of the time. We use what works 100% of the time...end of discussion.

This isn't a part time-job for us, a hobby, or a whim. This is my life, and the life and livelyhood of 7 other employees. We arent working out of someone's house, or mascarading as something we are not.

So when I give a recommendation, I mean it.

 

^^^Well said Sharif! I've never heard a single bad word about Forged Performance ever. Only rave reviews of all of your work! That's exactly why I didn't mind paying a little bit more to have a shop comparible to FP (GTM) do the work on my car. Some people on this forum talked ish (behind my back of course because they didn't have the ***** to say it directly to me ) about how much I paid for my setup and that's fine. That's their opinion. But in the long run I know that GTM will take care of me (like they already did once when my SC went bad) and that what they recommend is always going to be in my best interest and the best interest for my ride. They also won't let a car leave their shop until they know it's 100% ready to go. Could I have saved a couple grand cutting corners? Of course. If I could go back and do it over, would I do it differently? Hell no, because I have the piece of mind knowing that GTM will back me up if anything goes wrong.

 

+10000000000000000

Living example here..........

The only problem I had was, I could not find the FP gas card Sandy promised me Plus I had to fill up more than once from Atlanta to Houston.... Other than that...zero problems.

BTW.......Ouchhhhh

 

I'm sure that there are capable clutches that are cheaper than the exedy twin carbon thats in my the car now. But for my peace of mind I chose to overbuild. Some people are looking to save a few hundred dollars by installing a less expensive setup, and thats your choice. It might hold, and then again it might not. I have heard nothing but good things about the twin and triple carbon clutches(exedy or carbonetics), including quiter operation, smoother engagement and superior holding power. when bugeting your f/i setup on a n/a car, there are some things you shouldnt skimp on. IMO, your clutch shouldnt be one. factor in how much its gonna cost to replace your 600 dollar clutch (including install and buying a stronger clutch) if it fails.
