OK so here's the deal guys. I have a supercharger from a cobalt ss. For all who don't know its a screw type and will put out 12+ boost no problem. I am only looking for 6psi, so as i said, no problem. I am simply asking if anyone out there has done anything like this? All help is greatly appreciated. Also if its not going to work just tell me haha. Thanks
No it will not work. The Cobalt does not use a twin screw blower. It uses a roots blower, the Eaton M62. Besides it being a little small for the 4.0 to begin with, you cannot just slap on a blower off any car. It would need a custom manifold, intake, fittings, tuning, and many other things. Just get a kit made for your car. The XCharger uses the Eaton/Magnuson MP90, essentially a larger version of the one you have now and is a very reliable and proven kit
The M62 is to small for the 4.0SOHC. It would require 2.1" pulley to make 6lbs of boost or a 1.6" pulley to make 12lbs of boost. Both pulleys are too small to use.
