HI so Kim shelby in his infinite wisdom decided he didn't want to fit a supercharger to this Cobra as it was not going to be used on the race track. That was the only reason for fitting a supercharger when cars are raced. as engine wear takes away performance this car has now done 158 k miles far beyond what a car racer would have allowed it to go before an engine rebuild. they used to do this at every second or third race. so if you are even thinking about doing such an extreme modification it would be considered fool hardy as blow it up you most certainly would into little pieces.
