So first of all.... Shout out to all the shops to use CNC to port these 1.7 Super chargers. I wouldnt take on this project again. There is SO much material to remove, doing it by hand was exhausting.
I would consider what I did to be a fairly aggressive port. The only area I didnt really push was on the back side of the drive on the snout. Controlled tooling was very hard to get back there, and there was no chance of a tig fix if I went through. (unlike the side of the main case, whoops) I also welded a couple other areas of the snout before starting the port work.
Not as pretty as the CNC jobs, but should be effective! Heavy port work on the snout and case. Light porting and opening on the rotor exit. Light porting on the coolant passages. Deburring only on the intake to head ports.
Pictures all here...

Hats off to you man. That looks tedious! How long did it take you? I'm guessing 10 hours, based on the "10hr" tag on the imgur page but don't want to assume since we all know what they say about assume.

I think the 10hr tag was when the pictures were uploaded? Not sure. I have maybe 30-40 hours into it from start to finish and maybe 100 bucks in consumables. Thats really why I said I wouldnt do it again and would just pay a company to CNC.

Daaaaaaaaaaang 30-40 hours??? Yeah, way more cost effective to have a "professional" do it at that rate. Seriously though, I applaud you. I wouldn't be able to hack it

Well done. I ported my own throttle body. That was about 1% of what you have accomplished here.
