Clutch Started to Slip....sooo

Please share what aftermarket clutch you will be using.

 

Thanks for the pix and the information... all really interesting.

 

check that top center bushing/mount on the transmission.... it is rubber & will dry/crack/fatigue.... You really may want to replace it for the extra couple hundred while she is out=-

Daniel at Ricanbi has the removal tool to get that mount out...

I have the kevlar clutch in my 6 speed- 3000+ miles 1 year later still love it, supposedly they have a break in period...?

 

Vivid, can you post the weight difference between the Aasco and stock FW and the clutch kit (pressure plate, disc)

 

Rob- I am now hearing about a ceramic clutch plate from at least one source. Related to ceramic brakes. Have you heard any rumbles?

What kind of driving were you doing that caused the clutch to go so quick? (Any track days, etc).

 

Don't you saw his exhaust testing videos?

 

Very curious to see how this flywheel/clutch combo works with the F1 system.

 

Me too, anyone in Florida put this combo in? I'll be needing it in the not too far distant future...

 

I was asking myself that question. Specially when the flywheel rotating faster than normal and the TCU having stock setup. Maybe I'm just crazy but don't the syncro system of the power unit has something to do with the TCU and the revs reading?
Rob, keep us posted on your results.

 

If it works I'll do it in the near future. The biggest issue as I see it is how the flywheel will effect (if at all) how the angolar speed sensors work

 

I don't see a problem with the ECU and the quicker revving so much as a lack of sufficient mass at the flywheel to get the car moving in normal street driving. The ECU gets the same timing pulses regardless of the weight of the flywheel. However, there is a certain optimum weight for the flywheel. Yes, a lighter weight one will rev more quickly but it will have less inertia for transfer of torque to the driveline, which could mean needing more revs to get going or a different clutch engagement technique. That said, most cars as they come from the factory have flywheels that could go on a bit of diet, but I'm guessing Ferrari is pretty close to optimum already. I installed a slightly lightened flywheel in my M5 and it made a world of differerence for the better. I'm not so sure about doing that to my 360. It will be interesting to see how this mod turns out. I'm all for an uprated clutch material so long as the car remains streetable.

 

I wasn't aware that you could use anything other that original manufacturer parts, so a few questions spring to mind:

1. Is it not a bit risky to use anything other than original parts?
2. What's the impact on warranty?
3. Do you have any recommendations for a "longer lasting" cluctch for a F430 (2007)?

Thanks in advance!

 

Any update on this?

 

I wonder if you would have better luck with the kevlar clutch from clutch master with a F1 than I did. I changed a buddy's F1 clutch with the exact same clutch master kevlar clutch and the F1 system didn't like it at all. At first the car drove fine and shifted fine, but after about 100 miles or so the kevlar clutch didn't work well with the F1 engagement, and had a lot of issues engaging the clutch properly. Even after all different PIS settings with the SD3 the clutch master's clutch was ditched for stock clutch and car ran perfect immediately.

My buddy picked the clutch master kevlar disc for the same reason (longer clutch life), the guys at clutch master swears they have sold lots of these to be installed in a F1 car and they all ran good. Later they admit that the kevlar design may not work well for the F1 car, but will for sure work well in a manual car.

The clutch master kevlar disc required a matching flywheel, so the factory flywheel had to be sent in together along with the stock clutch to be lined with that material. For whatever characteristics the flywheel have to be machine down more in order to accommodate the new kevlar disc.

In any case I would never go this route again.

I have heard that exact story from quite a few who tried them in F1's.


The programming was done with a clutch with a different coefficient of friction. Sounds like a forseeable outcome to me.

 

Brian- I notice Rob is strangely silent on this one. I was interested in the results, but based on what I am hearing, no miracle is in the offing. Do you ever reline clutches or rebuild throw-out bearings or do you always use new parts?

I was really excited for couple of days because the car took off and drove perfectly for a short while. LOL!
