R53 Supercharger Apart, what else to change?
SO i'll update with pics here later tonight but basically my water pump gear was missing a tooth as well as gears all sharp, no oil in the box... bone dry and the case FULL of a pile of metal shards and metallic powder. SO yeah.... sending it into WMW and replacing it with a nice rebuilt one. Also doing the 17% pulley, Bypass Pressure Valve i guess it's called? for throttle response?, and then input/output gaskets and a belt. Oh and a new water pump. Is there anything else I should test, check or replace while i'm in this deep? SUCH a pain to get to the superchager, i'd like to not see this again for at least a few years
Thanks everyone! Really excited to rebuild this now with a new supercharger and pulley.... thinking cooler plugs, 550cc injectors, CAI after I recoop money from this little tragedy

The rear PTO housing being run dry is quite the norm on stock chargers.
what seals are you referring to as the input/output seals? All the seals and bearings should be replaced by the rebuilder, so no additional labor should be necessary on your end.
The BPV doesn't really improve throttle response, it moreso fixes the "yo-yo" effect around 2500 RPM where the valve is butterflying under the vacuum and unable to stay closed. It will net you a small amount more boost, and possibly a touch of throttle response.
Aside from making sure to order another water pump o-ring for the collar on the engine block, you seem to have everything covered.

No need to replace the block off plate o-ring, it's just there to plug the hole for the water pump had you had a non supercharged car. The only other o-ring you need to buy is the one for the waterpump collar on the engine block.

really? no point in replacing a rubber o-ring that is hard to get to and could potentially leak and require removing the supercharger all over again? I mean $4 is not a lot of money when considering the time it takes to replace it if it starts to leak down the road.

My bone dry s/c was still turning the water pump somehow. It's an 02 with 95k miles.
I did the thermostat and housing while i was in there. Pretty sure it was never done before.
Wish I would have done the tensioner pulley too at the same time. Put it all back together and the thing was making a lot of noise. Couldn't really here it before with the s/c grinding so much.

WOW 1400usd for all those.
That rebuild charger must be close to 1k.
I would ask for hard data if the ported charger did actually made a difference vs regular rebuild. I'm pretty sure they charged extra for porting the supercharger.
As far as the bypass valve i simply opened up the valve and spread the spring. Next, i adjusted the flapper stopper to fully close. If you are not mechanically inclined dont attempt it. Are you required to surrender your core (bypass valve) to the vendor?
Is your thermostat housing cracked and leaking? I dont remember messing with the housing when working with the supercharger.
Valve cover spewing oil? Re-torque the valve cover bolts and see if that fixes the issue
