Making an Electric Pulley - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Sorry dont know where to post this one but here goes.

Is there anyway to make an Electric pulley (on/off Switch) or even better VIA RPM something like the ac compressor pulley but I want to use it for something else.

I have no idea what you're talking about, so you'll have to give some more specific information.

12v or 240v?

Draw us a picture and we might come up with some ridiculous suggestions.

Are you going to make your chairs electrically adjustable?

I smell a supercharger that is linked to an airconditioner pulley that will drop out when the turbos are on boost.

Am I close?

Actualy Hugh Keir is the closest I have a Vortech V1 Supercharger that is laying around, I checked for space and I cam make it fit instead of the power steering Pump... Loose the power steering and fox the V1 instead.. I however do not want to use it on a manuel pulley that works full time.. I want to make it into a clutch.. a custom bracket and fitting is not a problem I just want to loose the manuel pulley to an electric .. Preffrably at 6-8 PSI and I do not know how to make the conversion.. dont know if its possible..

I don't know much about air conditioner pulleys, but I believe the shaft is magnetically coupled to the pulley and should only require a power supply through a relay.

There might also be some larger air conditioner pulleys fitted to a bus that might give an improved driving force.

All that would then be required is a system for controlling an external device such as the Motec.

Stock A/C pulley is alittle big might be good for 3psi if am lucky heheh will open one up see how it goes... I know Motec is the ECU I have to get. Problem I seem to spend my money in other areas right before I have enought for one

Air con pumps generally use an electromagnetic clutch to engage them, and this set up has been used in the past in Super-Turbo charged cars, I seem to remember the Koenig Competition, a Ferrari Testarossa with 2 turbos and a supercharger used this set up. If you're after a cheap and cheerful way to test it, why not use a pressure switch in the manifold? The simplest ones are oil pressure switches, An adjustable one would allow you to set a pressure where the supercharger is disabled and the turbos take over...

Sounds like an interesting project...
