Can you give some more details? What was the actual sound? was it a metal clang? what do you mean by pop? did you hear any metal clanking sounds after?

Where you able to shift into other gears? When you were turning over the engine after it stopped can you describe the sound? did it sound like the normal cranking that it always does?

I used to work as a German repair specialist and might be able to help

I would totaly disregard anything said in this thread. There are too many variables to diagnose the problem. I did pretty much the same thing once in a 1969 Mustang, and everyone swore I blew the engine. All that happened is the rotor inside of the distrubutor broke. For $8 I was running again. Being that your car is a 95 it probably doesnt even have a distributor, I've never worked on a Porsche so I wouldnt know. Which is why you dont see me posting a diagnosis here. It could be alot of different things gone wrong.

Keep your fingers crossed and wait for the mechanic to call you.

Yes, a rev limiter will stop the engine from revving too high of it's own power. In this particular case, the engine is not causing the revs but the high speed of the wheels being transfered back to the engine throught he low gear. The engine can not possibly restrict this type of action.

Imagine if you had a wheel on an axle connected directly to an engine. Now say this engine can only rev at 500RPM and no faster. If you grab the wheel and spin it faster than 500RPM, you will force the engine to rev higher.

I dont know if its a turbo, but you could have done something to that from the over rev. It doesnt sound good though.
I hope it's nothing big and costly.
