300 Dollar Supercharging ..
#11
Im off to the junk yard today to see if I can salvage a Supercharger. They are usually the first things to go but its monday (the day they bring in all the new cars for the vultures) so I might get lucky. I talked to a couple guys I work with and they can help me develop/weld a plate/bracket to put it on. Should be pretty awesome when its done.

Ya a stock 12A 4bbl. Im working with a guy at work trying to see if we can fabricate a hat/cap that will fit on top and have a fitting for a 2" inlet. Not sure on the inlet size just yet, I dont have the supercharger. Im aim-ing for a blow through setup - much like this guys setup in his FC. Only difference is Im going to have an atmospheric blow-off valve, can anyone reccommend one? Im not looking to spend much - I have to put away some cash for Toyota Supra Parts (ya, I know its not an RX-7, but what ya gonna do).
And the hunt for a supercharger begins.....

You know, the best blower for this sort of thing would be one off a Mazda Millenia. a) it's sized perfectly for the engine b) it's a Lysholm type, so it would be much more efficient than the Eaton.

A positive displacement supercharger (roots/lysholm) with a carb has to be a draw through setup. Otherwise you're going to need one hell of a blow off valve... (and probably use a huge amount of crankshaft HP to turn the blower at part throttle)

I don't know, draw through would be a lot harder to fab up and i don't feel like buying a new carb. I didn't know that millena's had sc ?? I think sticking with a eaton would be much more applicable...
If you had a throttle at the blower inlet at might work, but that's going to do all sorts of wacky things with the carb (even with fuel pressure being compensated).
The millenia supercharger (on the 'S' model I think - Miller cycle engine) is more efficient that the roots type (read: cooler charge). It might be smaller too - I saw one once but don't know how large a comparable roots is. The rotors in the millenia supercharger are overdriven and spin at 21,000 and 35,000 RPM (they are different sizes) at max RPM on the V6 (this is why I think it may be smaller).
