boost press to oil press ratio ?

[chance cobb]

so i started thinking about this the other day . do you have to worry about oil getting squeezed out of the bearing surfaces if your boost is higher then your oil press ?

Unless your running a boost hose to an oil port/gally, then no there shouldn't be anything to worry about. Those are 2 totally different systems that really have nothing to do with each other and no way possible they can interfear with each other unless you have something major wrong going on inside your engine. The only thing close enough to let these 2 systems have problems with each other would be an oil seal blowing out of the turbo. Even then there shouldn't be anything to worry about as far as boost pressure blowing oil away from any bearing surfaces, except maybe ( but highly doubt) the boost pressure keeping oil from getting to the turbo shaft and bearings/ bushings.

Never herd of Air hockey style bearings? all the rage in europe

Why are you boosting your crankcase?

Again, there is no way you can get boosted air into the oil system unless you have some MAJOR unheard of issues inside your engine.

If your worried about boost pressure in your crankcase you got some serious issues elsewhere. Try to stop thinking so much..

This appears to be a new idea in technology so keep it quiet for now.

Actually I bet he was thinking ( too hard) of the turbo seals.

turbos don't have rod and main bearings
