Leaving nice Patch = Messed up clutch Well I have not tore into it but earlier today I dropped it down leaving a pretty good patch. I know I shouldnt have, the car has been sitting for about 2 months. Anyways now will not go into gear, pedal feels great. I have a spec master monster level 3 clutch (not sure what level that is for their present kits). I had to drive it home with no clutch, man that was fun. Pretty sure the diaphragm is jacked and bent. The monster clutch is rated at 700hp however so wouldnt understand how that would happen. O well I need to dig in and troubleshoot! Let the fun begin.

There was a thread a few days ago where someone had good pedal feel, but couldn't shift at all. turned out his clutch disc had fused to the PP.

Few months later finally found time to tear into it. Fused plate it is.... I will have to figure out what to do from here. The clutch is ten year old but less than 5000 miles on it. I will be in contact with monster see what they recommend.

I have been abusing clutches for 45 years and I have never seen that happen. What does the pressure plate look like? I find it interesting that there appears to be a ring in the disk in the same location on the PP side as well. Any idea what the disk material is? If the problem was on only one side I would suspect something in between the disk and flywheel but with the ring in the same place on both sides of the disk something else is going on.

If nothing got in there, them maybe there was a chunk of material in the disk itself? The last clutch I had in my car (Centerforce) had actually turned the flywheel blue and had heat checks ever 1/4". It never welded itself to the flywheel.

I believe nothing fell in there it was running great for couple thousand miles. There is no material missing from anywhere that I inspected. You can see the ring on either side of the disk and the pressure plate. It got super hot and either the material is not sufficient at the temps I got it to or there was a defect in the disk. You can see where the material from disk peeled away and adhered to the flywheel.
Here is a pic of the pressure plate.

We've not offered those units in a very, very long time... that is one of the first Monsters.
The reason it did what it did is heat, when it's slipped excessively, or, it slips itself the heat builds up and doesn't dissipate in the friction. This causes the friction to liquefy and essentially weld itself to the pressure plate.
This is very common in aggressive setups. That said, I've got much better options these days.

From what you are stating, either he cannot do burnouts, he does not know how to drive a stick, or this clutch is either defective or a bad design.
The flywheel has some heat checks, but I have seen a lot worse and the clutch did not weld itself. Am I missing something?

I don't think you're missing anything, I suspect the disk facing material was simply inappropriate for the application which would account for the comment that they have not offered that clutch for "a very, very long time". Like you, I have had so much heat in clutches that the flywheel was criss crossed with heat cracks but never once siezed up like the OP.

The clutch is 6 years old, he's not the original owner, he bought it used, and he's put 3,000 miles on it... that said, there's no telling what was done to it before.
What I do know is we stopped selling those because the price for manufacturing that friction became so expensive it would have made a $1000+ single disc clutch, which isn't going to work in the market. The friction itself is fantastic and very very smooth. As with any aggressive metallic based friction, if you get it hot enough it will liquefy and adhere just like this did. It doesn't make it a bad friction, but I would agree that this isn't the unit I'd have recommended for a cam only Fbody.
