I believe the problem will be the engine having to suck through the blower when it is off. This will be very inefficient, without building a plumbers nightmare of bypass piping. Volvo Penta marine diesels use a system where a massively overdriven blower cuts in on an electric clutch to provide instant off idle boost. As the revs rise and the turbo spools up the blower cuts out, and they have bypass plumbing to make it all work.
If you're not driving a manual you're really just steering.
i may be mixed up but isnt this just the cheap systems sold by places like CRS. where you turn the supercharger on or off by a swith in the car. its just clutch operated. but they are for fuel injected commodore engines so i dont know if it can work on a carby engine though id assume it could easily be adapted.
When the blower is off, the engine would starve and cut out.
Max's was only a blower body sitting on the carby. No internals!!
Yes the movie car was just a mock-up but why wouldn't it work. With the blower clutch disengaged surely there would be sufficient vacuum to cause the rotors to free wheel and allow the engine to run. Maybe not very efficient but it ought to work.
I just checked out the CRS kits. They have V6 and Holden red/blue/black six supercharger kits with clutch operation. In their FAQ it says this;
What happens to performance when the blower is not switched on?
Nothing happens as the clutch is free wheeling as on an air conditioner and when not switched on the vacuum from the motor rotate the rotors by themselves.
The V6 are EFI while the early motors are carby drawing through the blower. It ought to work the same on a V8.
You just need a check valve and bypass tubing between the carby and blower, so that when the blower is pressurising the intake, the valve is closed, but when the blower is off, there is a vacuum and the valve opens, bypassing the blower
Thats it, using a bypass for when its off would work fine... but a bit of work i reckon...
i was thinking also if there was some way to either gear it, or hook it up to a small electric motor so that when you disengage the SC the electric motor would kick in and spin the rotors at a much smaller velocity, not creating any additional pressure but just simply allowing air/fuel to flow through it....
