I am trying to get some ideas on how to execute putting together a roots style supercharger and mpfi. Right now I am running a 454 with stock tpi in my 1994 pickup. I have read all the articles on converting to port fuel but I cant find any on how to make the roots work with the port fuel. I'm very sorry if this topic has been covered in previous posts but I couldnt find any useful information.

 

Use a MPFI supercharger manifold from www.boostpower.com for 454, $100

It is made for a B&M 420 blower, then just machine and adapter to bolt a newer magnusson charger on top and your set.

Using old technology roots chargers dry doesn't work that well according to Holley, but who knows.

I am using one of their manifolds with B&M 250 charger, but I am running TBI on top and just plugged the port injectors.
