I've had the */c off of the car before, but I have never really torn it down to the shell. Nor has it been this clean (soaked overnight in CSC). Now, probably for the first time, we get to see just how Floz did his 'chargers.






Note how the bearing passages aren't threaded. There is no way these bearings were replaced.

You can pull them with a slide hammer and collet. I have that setup now. I can demonstrate it tomorrow if you like.
This doesn't change the fact that I don't think he changed the bearings anyway. Betcha your coupler is black ABS (OEM, and never replaced either).

Actually, that coupler was replaced. It was green, and in good shape. It'll go back in. Is there any improvement that can be done to it? I've given up on finding a Gen3 TB, so it'* time to get maximum flow out of this...abomination.

They aren't bad. They are a little smoother than the Genny3 case I have. Not sure if this is the case or not, but maybe those aren't score marks....maybe bore machining?
I had planned on sticking in Gen3 rotors into the case, but the ones I have are losing their coating. Might as well stick with the Gen2 rotors in this case. Stock pulley is going back on until the OBD2 system has the bugs worked out and I have time to learn its capabilities.

The case looks like it was intentionally smoothed. Your marks go longitudinally in some areas. If that'* true, it removes material and hurts the efficiency of the charger.
All you need is a little inlet and outlet work, then the Magic Coating (wren'* special sauce).

If you look at most of his auctions on eBay, they say "Rotor needle bearings are repacked with high temp grease." Which means he'* squirting grease into them and shoving the rotors back in. Not changing them.
Under his American Supercharger name, where he sells his "premium full rebuilds", he doesn't tell you what parts he changes and what he doesn't. I'm sure that he doesn't change the rotor plate bearings and seals, though.

I have this now for the needle bearings (required for a GenV):

I don't have pictures to show it, but the nosedrive WAS rebuilt. It had a blue anodized bearing at the pulley shaft. I too am doubting the plate bearings were replaced. Then again, those bearings typically don't go bad.
The needle bearings looked to be in pretty good shape, but I don't think I will chance keeping them. My only holdback is locating a hydraulic press (though we do have giant C-clamps in my shop at work). We also have pneumatic grease guns, so that will make extracting the bearings simple.
The hardest part is going to try to strip off the paint. I like the color, don't like the lack of knowledge on its ability to radiate heat. Painting the wrinkle finish on that may very well be detrimental. Aircraft stripper, as powerful as it is, did absolutely nothing to the finish except clean it a little bit.
