Supercharger Electromagnetic Clutch

[Guest Steev]

I was thinking of using an electromagnetic clutch from an A/C compressor for the pulley on a supercharger idea I am playing with. I need ideas for the intake, I can't just splice the s/c airstream into the normal intake as it would just fill the engine and any excess (boost) would head out the air filter(path of lesser resistence). Is it possible that the supercharger would free wheel enough to meet the consumption of the engine?

i've thought up similar ideas before and if just sucking air through the s/c causes too much vacuum (so to speak, and most likely would only occur if using a positive displacement s/c) you could probably use one of these: http://www.mccordcg.com/mpp/mpp.htm

 

just have your main feed pipe from the s/c, then have a secondary pipe with the valve on the end (closest to the s/c pipe). hit a switch to turn of the s/c and open the valve at the same time and that should work pretty well. the only problem i can see is weight might start getting a bit high and i've heard that in some cases those valves don't seal the greatest, but i'm not sure.

 

a somewhat basic setup could look like this (sorry for the paint like drawings):

 

a bit more compact setup with a single filter could look like this:

 

there's a chance that if you did the design like the second one that you'd need two valves, one at the beginning of the "crossover pipe" and the other at the end as pictured (the black line). the maf, if one is used, would definitely have to be mounted before the crossover pipe so that it would get a proper reading (which might make the second drawing a bit easier to do.)

Mercedes supercharges have the clutch alreay installed for you. I have a Eaton M-62 supercharger from a SLK230 on my bench right now. My original plan was to use the supercharger wet with a carb. I scored a set of Tripple SK racing Carbs and now will use it dry. Still working on the detials.

another idea is a supercharger bypass valve that re-directs the airstream. This makes for a rather complicated manifold setup, but with twin-charged applications it can make huge power. ZZperformance.com has a twin-charged grand prix I have seen in person; it ran low 10's with ease... should be in the 9's with some tweaking. Oh, and it's a wrong-wheel-drive street car.
