also, is that your needle bearings full of metal shavings? If so, you're probably going to want to replace those.

It matches the angle of the rotors pretty well. This is just an extra gen 3 case, I have a complete L32 w/gen V in my car now and another gen V on the shelf so I'm not gonna be using this, I may work on the inlet next and pop those bearings out an sell it or I may just take it in for scrap.

Also...porting a GenV is worthless...bench dyno proven.

I'm not gonna hog the gen V out like this one, I really just need to remove the H bar for my intercooler and I will probably smooth all the rough casting areas out. This was really only to get practice and mainly to see if it would even work... If anyone else wants to try it with a router I used all standard grade wood bits just at very low speed so they didn't heat up and burn

I gotcha.

I believe polishing the inlet/smoothing the outlet like you mentioned would be the only thing to do...basically diminishing the imperfections from the factory, even though there are few to be had on that blower. Steigmeyer (or however you spell that), that ports the Cobra blowers...tried their funky outlet "rain drop" or tear shaped outlet...and it actually lost a decent amount of boost from it.
