I've got an 88M6 that I may decide to do some mods with. One of which is a supercharger system. Let me state that I know very little about any of this. So, if the logistics work out on compression ratios and whatever concerns I should, then hopefuly this will come down to a matter of making it fit.
So, please throw some things at me regarding supercharging an S38. Compression probs, new MAF, ECU issues, etc. ANything you guys can think of that may stop this project before it gets rolling. As always, thanks for your time.

is it possible to pressurize the whole plenum instead of just the manifold. I ask this because I'm considering a twin screw design, and these seem to be direct bolt on to manifolds. I'd have to fab something away from plenum, or refab plenum as well. Any help?<br><CENTER><IMG SRC="http://members.roadfly.org/hughes/My.gif"></CENTER>

HI Patrick

I got the bug too, would like to get more out of my Euro 85 635. I've been reading a very good book by Corky Bell, "Supercharged". Look for it at a book store.

First you would need a Counter Clockwise Supercharger. If you sit in the drivers seat, the engine turns over CCW. There are kits out there, but at over 6 grand, thats too high for me. I was thinking about building my own kit. Im a CNC Machinist and have access to machines.

Also the supercharger should run into a intercooler.

Heres what I have come up with so far, as far as an Idea. Im new to supercharging, but have a plan of attack,,,ehehee

CCW Vortech V2-SQ, mounted above Alternator. Build a Pulley that extends beyond crank pulley. Then I would have to remove the fan, no clearance. And use an Aux Fan mounted on the front side of the Rad. With this mount, I could still keep the stock belts and pulleys.

Run 3" intake tube off the back of the Charger to the air dam, with a KN cone filter. On the air intake, connect the AMF, hoses, vacuum lines. Then run the output from the Charger to a cold air box (intercooler), then from there run the tube back up to the Throttle body.

Add larger Injectors. Add a Bypass Valve. So when the throttle is backed off will at high rpms, the bypass valve re-routes the pressure from the charger back to the air intake tube.

Anti-knock sensor. And a ECU to correct timing. And if possible, reprogram the Chip.

LOL....not very easy, lots of work. Not sure I can or really would take this major project on, But it might be possible.

good luck

Thanks for that posting. I know even less than you so far. But it looks like I would go with the twin screw design as opposed to the turbine vortech type. I don't know if this would require a difference in rotation or not (clockwise/counterCW). Also, if you're running less than 13 PSI, I read somewhere that the intercooler may not be necessary, especially if you've got cool outside air coming in. If your intercooler is not up front getting fresh air, it may not be too effective either. For those reasons, I have opted to go with the twin screw (Eaton, Whipple, etc.). I'm not a boost junkie looking for anything greater than 13 psi. I'd be happy to get 9lbs. Everyone keeps mentioning Corky's stuff, so I guess I'm headed to the book store. Let's keep each other posted. We must bring supercharging to the masses of 6ers!<br><CENTER><IMG SRC="http://members.roadfly.org/hughes/My.gif"></CENTER>

That link was pretty good. It mentioned they have a CCW assembly that would fit on or replace the front end. Ah, situation is getting better already:)<br><CENTER><IMG SRC="http://members.roadfly.org/hughes/My.gif"></CENTER>
