about how much material did you take out of it? and can you get the oil at the parts store or do i need to go to my stealership. sorry for all the questions, but im going to tackle this and i dont want to be caught with my pants down, it also looks like i can toss it on the mill at work so ill probably do that, that way i know its all even.

It was alot of material that's all I can say. I already had a couple of bottles of the oil. Not sure if you can get it from your local parts store. But yes you local stealership should have it.

I did also port and polish half way up in the inlet. But its so minimal I cant see to much of a gain in hp compared to doing what I did to the outlet. The path the air now takes in the inlet is alot better now.

Yes.. you are correct.
The inlet is the critical part because you want to allow the rotors to fill as much as possible.. if you think about it, whatever air is sucked into the supercharger is going into the engine no matter what and changing the outlet port wont help get more air into the supercharger.
i'm quite concerned with how much the outlet was changed on that unit. especially the backflow ports.. That thing is probably quite a bit louder now..

By opening up the outlet ports the faster the air is moved past the rotors with less heat. And pick up more AIR volume with the port work done. If you just open up the inlet and not the outlet you have more air being compressed with possibly more heat and not much of a gain due to the smaller outlet holes. That's why its is good to do both if you can and or have the money. All I can say is that I did it and felt a differance
Everyone has different set ups on there car's thus you will have different out comes with the same Mod. Some might say they felt nothing when others say it's the best thing they ever did. I'm sure if you had the car retuned there will be more of a gain.

We port the outlets on the M90s as well. It results in huge gains on the Supercharged Thunderbirds. We also reshape the inlet and then polish the whole thing. Usually good for around 25-30 wheel horse. Also the charge air temps are reduced which help prevents heat soaking the ATA charge cooler on the supercoupes.

How do you regulate how fast the pressure is sent back into the blower hosuing? Size
Although.. they were mainly placed there for noise concerns..
IMO.. you'd be better off having no slots, but that would be very hard to do without destroying the housing diameter.
I do agree however, making some of the edges smoother and rounding corners will help.
