This is all I know about this but I think with just a good tuner it could easily go in the 12"s I have never race her but she is one fast go getter. Top end is not enough road around here to do it all but i did see 145 and still not close to red line. The below statement comes from inside... True or not I have never done it but I do know this is a quick has they come. Porsche Boxster s 3.4 6 speed <>non turbo.. Now the price you pay for the ride is a little out weigh but the excitement of owning one is awesome.

And it goes fast. But launching the 3,100-pound Boxster S for maximum acceleration isn't a subtle affair. Dump the clutch at about 4,800 rpm, and after some destructive-sounding axle tramp, the car whomps to 60 mph in 5.0 seconds. The quarter-mile goes by in 13.4 seconds at 104.6 mph.
