[Build Thread] -- Journey to 700+ WHP [Supercharger]

milkcow500 · 06-26-2018, 11:32 PM

This has been an ongoing issue with this blower for a number of years. What's happening is that the output shaft seal is leaking hot compressed air into the housing, which causes the oil to plash upwards. The only real solution I've seen to this was to plug BOTH sides, since it is a self-contained unit.

Edit: Rusty's idea sounds pretty good imo.

Isn't plugging both holes risking seal blowout even with the upgraded seals?
I'd love to do that but am too worried that the little breather really needs to breathe. I would have thought it's designed that way for a reason.

I've been told that it isn't necessary, but it's really not a definite known. To put it in perspective, the procharger is a very similar design and it does not utilize a vent plug. I know a couple people who have ran with no vent, but no real long term testing yet.

It is,

Mine did this when it was still stock @ 9PSI, I had fluid all over my windshield. Funny cause they tried to blame me at first saying I had power washed my engine and push water into the unit :/
