I'm wondering if it is actualy possible to hook up a clutch to a super charger and still have it work....

i know that some MR2s and other cars have been designed to do it, but is it really possibly on a carburated engine running a roots type super charger...

and have anyone seen this done sucessfully??

a virtual penny for your thoughts??

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.

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.

No it's not.

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!!

Clutch driven superchargers exist for small capacity engines. I don't know what type of blowers they are.

I don't know of anything for a roots blower, which wouldn't, I imagine, allow the engine to breath when not running.

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;

The V6 are EFI while the early motors are carby drawing through the blower. It ought to work the same on a V8.

Could be made to work quite easily!

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....

Would that work??

the crs blower is just a toyota 2l blower. crs make them fit anything from harley's to commodores and anything in between
