Just wondering am i missing something off the bottom of the supercharger or if not how do i build a custom box. I know that the little butterfly valve is the blow off valve but not sure if it is included in the box or is external. I want to do something like this only with one supercharger on one side or the other.

I believe what you have there is the GM M45 blower. It could be a 90. The chamber looks kind of short. Do the lobes have a blackish/grey finish or are they plain cast? The butterfly valve is called a by-pass since it doesn't vent to atmosphere.

its a rebuilt M90...

why don't you check out that guys website? he has everything that he has done to that to run dual m90's ... the thing is his project has taken him 2-3 years to finish and it has so much custom fabricating that it would be a bitch to replicate... good luck but IMO just stick with a single m112

From that blower what you're missing on the bottom is the GM lower intake. It might be easier to fabricate something using a supercoupe blower.
