Default Polishing an M90

Cost was:
1 Black and Decker RTX
3 80 grit flap wheels
3 120 grit flap wheels
5 180 grit buffer wheels
5 320 grit buffer wheels
A little metal polish and a polisher wheel.

Pics are huge and there'* a pile of them. I need to take some before pictures of the spare casing. That way, there'* before and after.

When I began on this project the realization of potential is amazing. The casting is extremely rough. I could probably have seen nice gains by only using the 80 grit to take off the majority of the roughness. I went all the way on this one though.

Gaskets are ordered

Kinda participated remotely. Bill leveraged a bit from my M62 work, and I learned a bit about the M90 work from him as I followed along the last couple days. Good news, as I plan to tackle a couple M90'* this winter.

thats why you didn't respond to my PM about the supercharger casing. Looser that was my Idea. I want your other casing on the car. .

Good work Boosty. Now I can copy of your work for my M90.

My goal on this winter'* work (another Gen3 M62) is to emulate a key feature on the GenV into my next SC. If the GenV is sand cast (rough) like the SC'* I've seen, polishing at LEAST can gain you power and efficiency. I'd LOVE to get my hands on a GenV 62 or 90 just long enough to LOOK and compare. And to confirm my suspicions about where the inlet design came from. Boosty and I have spoken quite a bit about my suspicions on the inlet design.

When I get it I'll take some good pics of it so you may be able to compare.
Just looking for some guidance on what to look for and where to do it. I don't want to mess it up.
What are the major differences between the Gen III and Gen V besides the rotor coating and rotor clearances

Bill... I barely posted and went to sleep. Did you like the change from the prior pics to the new ones on the blending etc....as usual you didn't respond to a pm.

BTW everyone..Ole Green and Grumpy helped with advice (like that'* a surprise to anyone???)

Olds.. I didn't reply..because I read it at work when I couldn't respond. And no.. you aren't getting the casing off my car. I might sell you my other spare casing though. (This one plus a fully complete charger is sitting on the bench.)

Paul...if we knew the differences...we wouldn't need the pics..lol
