Sorry, you are quite wrong here... The walls of the blower wear in and get those grooves.. that is because there is a nearly postiive tolerance between the size of the rotors and the case...
The reason it is ruined, is because the outlet port was made larger... this will prevent the sealing ability of the rotors, letting boost leave through the way it came in.
I can see the point about the outlet port. But getting back to the internal walls, the ones on my Fiero are still smooth and shiny and my supercharger puts out 11 psi of boost. My boost is so efficient that I'm working on the intercooler right now to get the last few degrees of KR out. . Maybe the strong boost is there because I run the series V supercharger but I cannot believe that grooves or ridges on the inner walls have nothing to do with boost. Maybe it just depends on how deep they are?

I got my headers done, painted, wrapped and baked. I started building my y-pipe after i bolted up my transmission.
It looks like it will clear everything, i might have to modify a little after i got it on the cradle, but i want to drive my car for as long as possible. It will probably be coming out next week. I got my fuel pump ordered from TREperformance http://treperformance.com/i...-pump-1984-1987.html Its a knock off of the walbro i figure it's worth a shot, i'll make sure to post if i have a problem with it. http://treperformance.com/i...-pump-1984-1987.html My computer is boxed up to be sent to GMtuners. It took me literally 30 minutes to modify my thermostat housing. My motor mounts came from Purple Reign. Every thing should be wrapping up in the near future. I'm ready to start powder coating tomorrow.

Well it's done and back together, sorry for the lack of picks in some areas, i forget some times.
I'm still trying to stay off it because the clutch is not broken in yet, i noticed a small amount of slip when i give it a little more throttle in 5th gear, is this normal and will it go away when the clutch finishes breaking in???
