Clutch stuck engaged...

What is wrong? I think it is the friction plate stuck to the flywheel. Clutch pedal feels normal. Any ideas? It is a Spec 3+ with thier flywheel. Happened durring the burnout. Pretty sure the guy did not put me deep enough into the water box. Tires did not spin and the car lurched and died with heavy clutch slippage (had the line-lock on).

Well I vacuum bled the hydraulics and the fluid was clear. There was some air, but it did not change anything. Looks like the trans has to come out.

yep, you welded the flywheel to the pressure plate. I did this with my last 3+, it got hot on the launch and stuck together.

What clutch to you run now? Did Spec do anything for you? This is stupid. A clutch should be designed to not do that.

Well, what is going on??? What is your car doing?

I've seen a couple of clutches "welded" to the flywheel. We actually have got the un stuck by driving the car lol. Just hold the clutch pedal to the floor which will keep the pp in the released position. The go out and drive it...changing gears by rev matching. Once you get it into the higher gears like 5th or 6th just stab the throttle wide open from a low rpm and I bet the disk will come un stuck...just keep the clutch pedal to the floor during the whole process.

My old man done this on a customers car once and taught us all a lesson. Since then we've done it one other time and it worked then too...in both cases the clutch keep working fine afterwards.

When the clutch pedal is pressed in and the trans in gear, the car will be in gear. So when you start it in gear, the car rolls.

Jon, I tried driving it in the pits and it did not give, but that was like 10mph and in 1st. I will see if I can try higher speeds and gears. I also put the rear in the air and tried working the e-brake while in 3rd. Prolly not enough inertia. Wouldn't a lower gear work better? More torque?

A higher gear will be more likely to break it free. For example, when a clutch begins to wear out, it will show signs of slippage in the higher gears first. The engine is going to make the same amount of torque regardless of what gear its in. Ever tried to do a burnout starting of in 5th gear? Probably not, right...but if you did you'd probably slip the clutch not the tires. The lower gears have more torque multiplication which would move the car easier and put less stress on the clutch itself.

You should be able to take of in 2nd gear and work your way up to 5th or 6th as long as you don't have to stop. Just rev match your shifts. Hold the clutch pedal down the whole time and it will probably break free with some heavy throttle...

I just want to see it..sounds interesting..

I went around the block. Luckily did not have to stop. Went up to 5th holding the pedal and it did not break loose. Tried holding the throttle, tried stabbing and coasting, nothing. Only got up to about 50 or so. May not be making enough power that low in the RPMs to break free. I think I may try again over the weekend at a higher speed.
