Had a stinking hot day here recently and got a little concerned about my oil pressure.Just wondering if you guys can post up what oils you use and what sorta pressure it gets throughout the rev range.I have a mk1 BA and using Penrite HPR10w50 ATM and that particular day is was around 33psi at idle around 55 cruising and aroun 65 when I'm spirited. The usual cold days idle is around 45-50 at idle so I'm a little concerned. Anyway can you please post up your pressures If you know them just for a comparison.Thanks, Dave Link to comment Share on other sites More sharing options...

Thanks for that info. I imagine that housin would drop oil pressure a bit? Link to comment Share on other sites More sharing options...

I think the spring pressure on the relief valve is modified as well. Link to comment Share on other sites More sharing options...
