Maybe the guy behing the wheel was so fat that the turbo lost all its advantage over your boxster.


On a more serious note, I think the turbo push a bit more than the boxey, even if you keep the turbo under 4500rpm and use the boxey's full potential. In other words, I'd be really surpeised if the turbo kept between 2000 and 4500rpm isn't faster than the boxster between 2000 and 7000rpm.
