Rb 26 Bearing Wide Clearance

[datsun_1600]

The best advice I can give regarding max oil pressure is about 10psi per 1000rpm. So on my Datto engines I set it between 85 and 90PSI for a redline of 8500 to 9000 rpm. I like to see a min of 25psi at idle (hot) and 50psi by about 2800rpm (hot).

My stepfathers ex John Atkinson Works rally Subaru, runs a little more than that. It see's about 90psi, even though the engine only revs to 7K.

The works LZ works Rally Stanza's were set around 90psi for a 9000rpm redline, the L series variants ran a tad lower (but had a lower redline)

Just my 2c. I'm no RB expert!

I think what he was correctly saying (along with a few others) is that a hydrodynamic bearing generates its own oil film. What you have described is a hydrostatic bearing.

I just wanted to point out that a hydrostatic bearing becomes a hydrodynamic bearing once the journal is rotating.
