I've started my supercharger rebuild today and while I have everything apart i'm going to just port it all out. Once I had the turbines out i put the plenum back on and i noticed that the plenum outlet is smaller than the supercharger inlet so I'm going to port it out to match the supercharger. Also I was looking at the other plenum and noticed that the outlet on it is smaller than the inlet on the intake manifold so i'm porting it out too. I've already grinded down the lip on the inside of the plenum and started using an engine hone to bore the plenum out. Once I'm done I will use some 2000 grit to get it all smooth and then polish it out for a nice flow. I'll take some pics and post them also. Also how much h/p do you think I will gain on doing this? Thanks
