I just had maybe 50 miles on the Procharger P600b and driving down the freeway, stepped on it a bit and a hell of a racket. On close inspection the upgraded impeller with curved blades that is supposed to be billet aluminum fell apart I had over 35 thou clearance, all new bearings. I say it had to be the impeller failure because some of the blades (short and tall) show no contact at all. Of course it took out the rear impeller bearing. It looks like the bearing cage that got torn apart is plastic-so I'll drain the pan and spray it out with brake cleaner and should be good there. it may have dropped a couple of intact ***** from the bearing and I'll get those out too. Then clean out the intercooler. at least if any little bits got thru the intercooler it's all aluminum.
So does anyone know of an upgrade impeller for the P600b that's relaible? Does the D1or P1 have the same diameter and impeller shaft size? I got this one from superchargerrebuild. I know some have had good luck with them and sone folk have not-I'm in the have nots!

oh no!
procharger had their m1 marine impeller or something of the sort that is curved and will drop into it
their tech people are clueless about it, but their repair dept people know about it
I have the exact same impeller.
I had my supercharger rebuilt in 2017 and since then I've driven about 1500 miles every summer.
I also made a mistake during the installation, I had forgotten to put a screw lock on the bolt of the impeller and the impeller got a little loose and it touched the outer wall a little.
I was lucky and the impeller was not damaged at all and since then everything has been working fine.
At this point after double checking everything I'm thinking it had to be the high speed bearing preload. The only thing I'm unsure of is the location and number of wave washers. Otherwise assembly is pretty straight forward. I put one each at the front of each shaft. I did talk to Procharger for the info but kept getting different answers.
I would think that one washer on the blind hole side of each shaft would be sufficient to add some preload to both bearings on a shaft. If located on the through hole side, the shaft may not protrude far enough or allow for some axial movement which may be a bad thing.
I've rebuilt my Powerdyne a few times, but last time was about 15 years ago. I don't really recall paying much attention to the washers, but I see that 928 motorsports has some for sale, so it probably had/has some inside. https://928motorsports.com/product/w...superchargers/

What does Supercharger Rebuilds have to say on the subject?
I took detailed pics and sent to him. His assessment is the bearing failed first-either due to lack of oil (I double checked the oil injector so ruling that out) or lack of preload. I asked if you can apply too much preload and he responded that if too much you'll have difficulty turning the shafts when the front case is tightened down and preload is most critical on the impeller bearings. I've seen videos/pics of SC rebuilds with one and sometimes 2 wave washers installed. So my plan now is to add wave washers to the front case side until I can feel the bind when I thighten down the front case and then take out one washer and retest. The issue of preload and the wave washers is just not talked about-so I hope my (expensive) experience can help out someone else.
I share your sadness, I hope you can solve the problem.
It's good that you checked the oil nozzle, when I bought my own supercharger, the nozzle was blocked, which had caused the impeller bearing to break and then the impeller.
I have a separate oil filter in the supercharger oil line, I have changed it every winter and about every 1500 miles.
I cleaned the oil injector last winter and it was ok, but I will also clean it next winter.

What in line oil filter did you use? I think I'll add one just for the xtra insurance against a problem.
Superchargerrebuild sent more info-on P1SC he's seen where from the factory it had minimal preload-and the bearing would start to spin in the bearing pocket thereby adding more room and less preload. If then reassembled with same number of wave washers then it would be not enough preload. I had my neighbor who is a machinist look everything over and he caught that the flat steel in the bottom of the bearing pockets opposite of the wave washers show wear-indicating that the bearings were spinning in the pockets.

Okey, good info.
Here is a link to my project where last winter I cleaned the nozzle and changed the supercharger oil filter.
So much for upgraded impeller
