Uh... Wait A Second...

Reading this Car and Driver article.

That Weiand blower on Max's car...

It's a roots style blower, those are positive displacement.

That means if the rotors stop, so does the air; so that cute little switch on the shifter would kill the motor when it stopped driving the blower.


  1. Which is just how the pursuit special worked in the film. They didn't have any sort of clutch for the blower in the car, so every time Max uses the toggle he's either killing or cranking the engine with the camera on the hood.

    1. In Road Warrior the engine is clearly still running when he shuts off the blower.
