I took the radix off of my 03 Silverado SS and sold it to a buddy. I have the chance to get it back for pretty cheap. I do not plan on putting it back on my truck, however, I am in the midst of a LS2 swap in my 70 Chevelle. I am by no means a LS engine expert although when it comes to restoration and work on the older sbc/bbc stuff I consider myself above average. My question is will the Radix (MP112) work on my 07 LS2 from a CTSV ? I know a MP122 would be a better choice but I am more looking for the wow factor as well as a few additional ponies. I would be conservative and try to stay around 5-6 psi and hope for just a 80-100hp gain 400 factory HP to 500? One good thing is that being a ground up build I can engineer a adequate fuel system. The only differences I can think of are the fuel injector plugs...what else? I can run the truck accessories no problem I have a couple of sets of engine brackets. I kind of dig the way the supercharger looks as opposed to the rear facing ones with the jackshafts. What else should I be taking into account?

I have no input other than awesome chassis to swap a LSx in. I love those cars, it seems like there is a good number of people running the 112 blower on that motor. Why not do some research into the Caddy CTS V blower and their stuff of LS1 tech. I think they have their own section over there.

Correct me if I'm wrong, but I'm not sure the Radix pulley will line up with the LS2 accessories from the CTSV? Someone told me the truck pullies are further out from the engine block than on the LS2's. However, maybe you could just use truck accessory pullies? Or see if magna has a shorter snout for the blower that lines up? Not sure.

If you use truck accessories it will work just fine, as long as the heads are cathedral port heads(which LS2s are) the blower doesnt care what its bolted to whether its an LQ9, LS2, or LM7. Sounds like a nice project, throw up some pics
