Ive had a similar issue to a post before. A looser at uni had his daddy's new Ford GT a few weeks ago. He was going around talking crap that he could rip my car and any other car in the area, said he could do 12sec passes... Yeah right.
Anyways I finally ran into him one night and dragged this looser, and it was all over in a matter of seconds. I thought at higher speeds he might have me but he had no chance.
Anyway my point is you can argue all you want but kw's, power to weight etc, but usually it comes down to the driver.
