why would you?

With drag radials, the axles are the next weakest link.
But that is from super harsh, clutch dumping drag race starts.

I have pulverized my sachs organic clutch and it still (surprisingly) holds.

IMO, clutch dumping is one of the worst things you can do to your Porsche. Drive it quickly and smoothly so it can have a long happy life.

Not sure why you would want to, waht are you trying to accomplish ?

Get a nice tune with Brake Boosting enabled if you need to get a good leave for some friendly highway runs.

turbo498 is infamous around these parts
when dumping the clutch, does it only affect the clutch ( wear & tear) or it has an impact on the gearbox or any other parts ?

It punishes the whole driveline. Not a good idea unless you are trying to see what breaks first

If the clutch dumping doesn't break anything, the wheel hopping surely will...

I just noticed you are from Rocklin..I was up there a few weeks ago. Didn't see very many turbos, your car must stand out!

These are such nice machines....unless you have money to burn, I'd be careful. Evo has axles you'll likely want to buy soon, fyi.

Me, I like my car bills to be as low as possible....so I've never dropped my clutch.

dropping clutch gets you better times, but your trap speed doesn't change much. I just roll out and take bad time with a good speed.

Engage the clutch normally and then accelerate fully. You can hammer it all day if you like, but you will pay the piper when you burn up the clutch. Porsche was built as a high speed autobahn car or as a race car, but not as a dragster. A Corvette is better suited to that role.
