Single turbo 6 speed car. Only thing I don't know on my car is what kind of clutch, brand etc. It has. All I know is that its a performance clutch because its heavy and has never slipped at 600 hp. The noise is a chatter/grinding when letting it out going uphill so I geuss I want to say the more load the worse it is. Do not experience noise any other time. I can deal with it but was just a little worried if maybe its about to leave me on the side of the road.

You shouldn't have ANY noise no matter what the clutch. Noise while sitting at idle in neutral is normal but not in drive. You should be able to jack the car up and peek through the trans windows located on either side of the trans near the front and see what clutch you have. It also sounds like you might have a lightweight flywheel install aswell. If you're not sure, snap some pics and post there here for identification.

Could be a twin disk, mine makes all kinds of noises. Cruising in 6th trying to accelerate from too low of an rpm give me a ton of noise.

Next time I have it up on the lift ill look for the window. It's so weird. Sounds like grinding a gear but a little less severe. Only on slow let out up an incline but no noise or problems any other time.

I'll assume you are not in a higher gear going uphill or incline ? That coupled with the load can cause some funny noise/vibrations

Sounds typical,if you're at steep incline and driving up the hill slowly letting it engage,it will make noise until you let it fully engage

chatter is typical.

Maybe its just a weird type of chatter due to clutch design. But yeah I'm def in first starting off and if its up an incline I geuss meaning more load on it then it does it but sounds like you guys have heard this in your cars and its not leaving you on the side of the road.

 

[Kruso]

No... the chatter they're referring to is not specific to Supras, its on any manual car... put it in too high of a gear at a slow rate of speed and you're going to hear it.

Kruso, the noise I'm talking about is when you're standing still at the bottom of steep driveway and slowly releasing the clutch pedal ,that friction chatter noise is typical,sometimes you'll have some shaking,shuddering ,at least in my experience

Hey thanks for the replys. Sounds more and more normal.
