2001 SLK230 Kompressor supercharger

Good day, this question is for the mechanic types out there. Can anyone tell me or post in this thread the air flow path through the super charger while at idle and under boost? Also, I know there is a "flapper" valve that operates at the full boost mode how or when does that come into play.

Here is my thought. I have never owned a Benz and might not. I have a 83 Jeep Cherokee (last of the big ones) that I have built a 4.7 stroker straight 6 motor for. I am still trying to see if I can get better than V8 power. I was thinking of a turbo but this brick is not made to get to the higher RPMs. Then I thought of superchargers, and started looking. Please don't suggest that I go to an after market supercharger place for Jeeps and get one. I do not do that, I like to build my own Frankenstein stuff.

Anyway, I was looking on Fleabay and saw a Benze supercharger that had like an a/c compressor clutch system on the pulley and that is was lead me to really start looking at Benze superchargers. When I was diving deeper, I saw that folks maybe, did not like the clutch system or, that there were too many issues with it, ergo the supercharger in the title line.

Thing is, while I have been looking at the Benze chargers, I have yet to find a write up or diagram on the airflow path with the supercharger.

I'm not looking for huge amounts of boost, maybe like 6-8 lbs max, so if these superchargers put out more than that I would need to have a blow off valve someplace. As far as a "flapper valve" I was thinking of getting a generic one and maybe link it mechanically to the throttle cable so when the throttle opens, the flapper valve closes the bypass and the boost goes through the inter-cooler and into the intake.

thoughts, help, questions welcome.

Noodles, actually haven't decided on a model yet but it would need to be one that does not bolt on like an intake for a v8. Like for the 4 or 6 cylinders, well don't know if they make one for the 6 cylinders.
Ok, so maybe one from a 4 cyl would have the boost for my straight 6 I am looking for. I have seen a few that have, what looks like air intake on one side and after the supercharger, two outlets. Then I have seen one that looked like it had one intake, then a small outlet? before the supercharger, then one outlet after the super charger.

I might have an idea how both of these flow, maybe? but the 2nd might mount better to where I want it to go.
I kinda figured that, especially trying to use a benz supercharger on a old jeep. That's why I am asking on here for anyone that has a good understanding how the superchargers work on these cars.

Can anybody ask their mechanic, if they have a good trusted one?

Out of the two supercharges I posted, which one would be more adaptable to another car, if at all.

thanks gents
