Well I think you have the race won, I've owned both cars an 01 cobra and an 03 boxster( I still own it). Only way he can win is if you have a terrible launch or miss a shift. But be careful though, many ppl talk bad about the boxster but they are very capable cars, I actually beat one of the 2013 v6 mustangs a week ago, both cars where stock(boxster de-snorkled and 30 pounds lighter) and my boxster was running on 90 octanes instead of the 93 the car asks for. I beat him about 5 times from a dig and 1 from roll. Of course my friend is not a very good driver because I know that with a good driver I woudn't have won any race. A few days later he got me 4 times though, he would catch me every time at about 90 mph, so I only had the launch on him.
