How bad is this for the clutch/tranny, just like doing it at 2500RPM, so it grips right away. Will it wear away a lot of the clutch?

I know I'd be messing up my tires. But does the clutch get a lot of wear. Someone please explain. I only did once, but I'm just curious if it's really bad.

Thanks

 

Well, it's definitely not too good. It'll put undue stress on the transmission bearings. You'll burn the disc up faster if you make it a habit.

The bearings are what you should be worried about. Mine went, and it's costing me $500 to get them replaced. That's not including removing/installing the tranny (I did that myself).

I'd recommend slipping the clutch. That's how it was designed to be used. If you really want to make the tires spin, just get an intake and a ypipe. You can make the tires spin at will (no clutch dump) with that combo...at least I can.

 

Dumping the clutch will:

Cause damage to your entire transmission
Casue excessive ware to your drive shafts
Cause damage to your engine mounts
Cause damage to your clutch
Cause damage to your tires - but wait, thats ok?

 

Dumping the clutch will not cause as much friction *wear* on clutch disk itself, but the sudden energy will put an impact-type stress on the whole driveline. Kinda like the difference between stopping from 5mph with the brakes, or just rolling into a wall.

The friction disk has 6 (or 4 if it's an ACT/Exedy, IIRC) springs built into the hub to try to take out some of that shock - but they're not designed to compensate for clutch-dumping.

Remember the other thread about 'how hard you push your max'? I said I will "exercise" the car, but not do anything to add undue stress. This is a perfect example of undue stress. If you slip the clutch normally and run to 60 at WOT countless times and still not stress the driveline as much as a single clutch dump.

 

Thanks for the response, I'll stick with abuse for the rental cars. The only time I actually spin my tires is in the rain, that way it doesn't hurt the car or the tires much. Don't think spinning the tires in the rain will do damage to anything. (this is without LSD)

 

I had burns on my flywheel from doin it.
