Haro.. let'* answer the question instead of scaring people away from all modding. Afterall.. if you hadn't encouraged me.. I would have never swapped that first rice pipe onto the 95.
Goat.. mild porting and polishing can easily be done by anyone on this club. The easiest thing to do on the supercharger is to smooth the inside of the supercharger casing. Tthe surface inside the supercharger is as rough or rougher than the outside. This roughness will add to heat and resistance issues for air.
My first casing is well documented and posted here. I used nothing more than a dremel tool (or two
) and a lot of flap wheels in 80 and 120 grit, then finished up with a bunch of abrasive puffs. All items are made by dremel and easily available at Walmart.
Simply pull the rotors out, tape over the bearings in the casing and you can flap wheel and buff until you have a mirror finish. That little bit and a little rounding out some edges of the bypass outlet and egr port will help. Will it gain much time at the track? Probably not, will it help keep heat and KR down..sure will. I went a bit more extreme on my first casing because it was a spare and a test for me.
Now..while you are there and the rotors are out. Maybe a bearing change is in order. If anyone brings WillWrens step by step bearing change to a machine shop.. they can do it no problem. If you have the tools and feel comfortable, it'* pretty straight forward.
Then using GM red gasket maker put it back together and refill with oil. All ready to go.
I don't recommend going as deep and far as I did, but a polishing and smoothing of the rough surface will help air flow.
