Not to be rude, but I'm wondering why 500HP is your mark. I started autocrossing my 986S last year, and I'm finding that except for long straights, which are rare, the car builds speed so fast that I have a tough time keeping up, and that I make a lot of mistakes. The two fastest racers around are in a Cayman and a prepped 914. They're unbelievable drivers, and I know their cars aren't breaking 310HP ... they regularly beat GT3's!!
If straight line performance is your thing, I can understand it. I had a 71 Camaro for a long time. It made waaay more HP than my 986, and ran 12's in the 1/4mile. But that was about all it was built for (it sure did great burnouts!!) The Boxster is no burnout machine.
