Most of us here I think have seen the 1979 dystopic Australian movie made by Kennedy-Miller Productions by the name of Mad Max ( Or The Road Warrior in the US). Most of us also have long wanted to have the cool shifter with the pull handle for the 6-71 blower on it. Now, on the movie car it was a fake and the blower was gutted. However, would it be possible to make something functionally similar using a centrifugal supercharger like a Paxton? I know Toyota did it with the supercharged MR2, but how they clutched the blower I have no idea. So, I was thinking, why not just use a bypass valve that stays open most of the time, and takes away some of the parasitic drag used to pressurize the intake when it is not needed? Then, you could just pull a switch to close it when you needed the extra power, maybe by using something like an electric exhaust dump valve? Could you even make a blower clutch using some sort of dog-clutch arrangement that would decouple when the valve was open, but couple when it was closed? Now, as cool as it would be to do this, I am not actually thinking of doing it in the near future. (My finances barely permit me to buy gas half the time.) I post it really as a question of theory to give us something entertaining to discuss.
