Procharger Impeller Bed to Outlet Cover Sealing? Call me a noob to F.I., but the machinist in me is wondering why the hell there isn't a seal between the faces/steps of the impeller-side of the Procharger, and the outlet housing?
Call me a smartass, but it seems like we're trying to make clean, pressurized air...and that whole mating surface is one BIG boost leak and/or a dust & debris syphon!
I understand all about precision mated surfaces holding a certain amount of static air seal, but it looks to me like it'd be a whole lot more efficient at creating boost, and keeping the intake air clean if there were a simple "viton" or "butyl" rubber seal along that mating surface.
Has anybody else had this concern?
Addressed it?
Changed/modded it?

Thanks for checking a real-world test for me. That's exactly my point...why isn't there a sealed surface there? It's hard to tell what kind of boost we could make if there were - or how much faster we could generate the desired boost. Not to mention, if it's leaking air out, it will pull dirty air in!

My Vortech has a thin o-ring between the compressor cover and the backing plate.
I'd think any air leaks would still be small though, seems silly not to have a seal of any kind though.

That's what I'm thinking, too. They're definitely a good fit face-to-face, but as much as a Procharger costs, it oughta have a damn seal there!

Not a bad idea, but I'd almost be afraid of shearing off a bead of the silicone onto the inside edge when you put the cover on and it eventually getting into the impeller.
