Comparing one car to another does not make sense. More than likely, the two cars do not have identical tuning/modifications/driving.
More than likely its a real world situation that actually happend.

My car and chris's car where pretty much the same mechanically. I had an exhuast 3" exhaust with the silencer in it so it that negated any real performance gain.
Sweet picture though.
