So my girlfriends dad bought a 96 Porsche, and ever since I've been kind of curious who would pull faster from a stop, and from a roll.
If I have the specs right on the Carrera, it should around 5.3s 0-60 and 13.6-13.8s 1/4 mile.
I've done 5.4, I've seen quite a few other guys do 5.4, I'm far from a professional, so I'd say it's not too hard to do. We also have guys that are not professional, not running slicks, hit 13.5-13.6 with similar tunes. We also have guys that are good that have gone as fast as 12.6 with slicks. From all that, I'd say that from a dig, you'd probably be hard pressed to win, these cars don't do digs well. From a roll you should pull on him slightly. Hard to say because some older cars like that don't have a lot of data available on them, no one is putting youtube videos up of that car, I don't see any forum posts about it (briefly searched, I'm sure someone somewhere has something on it).
All said and done, this is paper racing, and what actually happens could be wildly different depending on how good/bad each of you drive.
