year........... just watched that the other day... soo much cheese bit its still cool, what i really want to know is how does a shot of nos blow the welds on the intake? and how does double clutching help you in a drag race.....

Unless the drag race involves changing down the gears then I see no way double clutching would help. It would probably hinder a lot

It slows the gear changes down and takes practice to get it right..
