When the car is running... it's all alternator. When the car is running there is a slight charge delivered to the battery (preparing it for the next "start"). Remove the battery when the car is running and... voila. Car keeps running (assuming a properly functioning alternator).

What? A Porsche is the only car with sensative electronics? I've done it on my Edge, and the electronics on it are FAR more sensitive than a 98 Porsche.

Has worked for me since, um, the 70's.

Cheers!
