Re: 987s around a track against a stock car with 75 more hp
Very difficult to come to any conclusions based on that video. We don't know the experience levels of the drivers, nor do we know anything about the chase car other than the stated 75 extra horses. We also don't know if the car is really trying to pass the boxster or not--it's obviously not a race.
Only thing one can say is that the chase car has a camera mount, which would lead one to believe that it's also modified in other ways.
