Ever been bothered by the fact that the Dukes has an extra that adds the blower with 750BHP text on the car, but made no performance difference whatsoever, having the same speed as one without it?

This is an OpenFormats edit of the car that makes it spawn only said hood extra (+ spoiler and louvers). I personally recommend adding it as a new car with it's own unique handling worthy of it's looks (included in the archive) while replacing the original Dukes with one that doesn't include the blower (such as JoeVK's Dukes Classic mod)

Note: Do not make it a gang car (or else the unwanted extras will spawn, that was the only way to get rid of them via purely OpenFormat editing)
