I was just going to message you. I replaced my CMC two nights ago and was able to go for a test drive today. All is good. I'm going to give it a couple days/drives then I'll adjust my RJM Performance clutch pedal assembly.

Glad to hear you got things up and running. All ready for boost now! :tup:

I'm actually surprised at how noisy this clutch is, even on the stock flywheel.
I know it's to be expected, but first and second are pretty loud.

I'm a little surprised.

I have the same one as you but with a 19 steel flywheel and the only time I can hear it is at idle after a long ride.

I have chatter in first and second almost every time. Occasional it "pops."

When does it pop?

m3chhawk 05-19-2013 08:43 PM

It did it on two occasions today. First was after about 150 miles all highway. Pulled into the gas station. Real slow in first and second. Did it two or three times while releasing. Very last bit of engagement. Car sat for ten minutes or so then about 15 minutes later at a light accelerating from first at the last bit of engagement it did it again. Out of the 900 miles or so, those are the only times.

I get a slight chatter after a drive and only at idle. Not loud, most people probably wouldn't notice. I have the 24lb SouthBend flywheel. I haven't noticed any "pops".

Do you have a stock clutch pedal or a RJM one?

m3chhawk 05-19-2013 08:54 PM

stock pedal, stock flywheel, new master, zspeed csc, southbend stage 3 daily, GTR dot 4

The only popping noise that I can hear is from under the dash when releasing the clutch pedal the CMC rod comes back and rubs on the the black rubber dust boot and makes a little popping noise.

^^ Yeah, I get this as well.

m3chhawk 05-19-2013 09:06 PM

Yeah I got that for the first 50 miles or so then it went away. This is definitely different. Almost sounds as though the bell housing is hitting a speed bump.......

Baer383 05-19-2013 09:23 PM

The only thing I can think of without hearing it is maybe a slightly loose finger on the pressure plate,b/c when you are at the top with the pedal almost all the way out that is when the least amount of pressure is on the pressure plate,other than that I will think about tomorrow and check your thread with any new thoughts.

Just a quick update...

The "popping" noise that I thought was coming from the clutch, wasn't the clutch. After driving enough, it finally did it when I wasn't using the clutch. I isolated it to slow speed, turning. After playing around enough, I found it was in the same spot, about 75% lock when turning to the right (hence why it was only slow speeds that I noticed it). I somehow bent one of the wire holders and it was banging on the brake line :ugh2:

Glad you found it and caught it before any real damage was done.
