I wanted to up grade my stock clutch because of my plans to add more horse power .. I have already added HD axles and other items to prepare for more HP .. The clutch was the last thing to upgrade on my list ..
I ordered a Exedy Mach 500 clutch as well as Exedys light weight SFI approved flywheel .. I got these parts from American Muscle ...I have had the parts for some time just waiting for some spare time to install them .. So Weds I was ready to do the install .. I pulled the trans and got the new flywheel in place and opened the box for the clutch and guess what ? They sent me a 10 spline clutch disc .. The car calls for a 23 spline disc ..I got American muscle on the phone and told them of the problem ..Just my luck they didn't have one in stock .. Many calls and many Emails to Alex to solve the problem , and they did .. American muscle got a hold of Exedy and Exedy UPS overnighted me a new 23 spline disc ..Alex and the guys at American Muscle did a great job getting me the right part and did it timely manner ..Thumbs Up to American Muscle ..
So the install is done , Bleeding the clutch was a problem but we finely got it bled .
OK so the good part .. I have not got into the throttle yet but from the short time I have driven the car it feels great Vs the stocker .. A bit more peddle pressure but not bad ..I had also replaced the clutch line with a Steeda Braided clutch line at the same time .. The clutch has more feed back than the stocker , feels more like a linkage type clutch now ..Engine braking is much stronger than factory ..You have more feel of the clutch engaging point . The lighter flywheel seems to have freed up some HP , it revs up much faster now ..I'm sure it's not making more HP but the lighter flywheel lets you get to the HP quicker ..
Now the bad .. None of this is too bad but you will feel and hear some sounds you didn't hear with the stock clutch .. With the car out of gear and clutch out idling you can now hear the gears in the M82 Trans rotating .. Push in the clutch and it goes away ..I can also feel the trans rotation in the clutch peddle .. Goes away with the clutch engaged .. I think the clutch line and slave still have some air in it because you can feel and hear a bit of squishing, crunching when pressing the peddle .. That should go away once all the air is out of the system ... The gear noise is most likely going to stay ..It may get quitter with some break in time ..( I hope ) I think the reason for the extra noise is the clutch disc , it has bigger stronger springs in the hub and most likely are transmitting more vibration to the peddle and shifter .. I can live with that for the extra holding power the clutch has now( 40% more clamping pressure ) ..The disc also has about 25% more surface area for better gripping power than the stock clutch ..
It's possible with a fluid change might help with the sounds coming from the M82 trans .. That is something I might try if the sound doesn't go away with break in ..
The new clutch needs 500 miles of city driving to seat correctly before I start really beating on it , so said the paper work that came with the clutch from Exedy .. Once it has broken in I'll let you know if it quieted down or it stayed the same .. I'm waiting on a MGW shifter and a Dyno Tune at Coastal Dyno before I head back to the drag strip ..
Thanks again to American Muscle and Alex for their help ...
