Hello,
Could anyone tell me at what pressure the later, non-adjustable valve should open? I originally thought that it was around 5 bar, but someone is telling me between 10-12 bar. This seems extremely high to me, but I'm certainly no expert. Thanks. |

I have no direct knowledge of RSR motors, but 5 bar (72.5 psi) seems a little low for a 911 relief valve so by default I would guess the units are 10 bar.

This seems extremely high to me, but I'm certainly no expert. Thanks. (IMG:style_emoticons/default/agree.gif) Don't have spec for RSR handy but here are several 911 oil pressure specs and nothing close to 10 bar. 1983 911 SC 4.0 bar @ 90 deg C @ 5000rpm 1991 911 Carrera 6.5 bar @ 90 deg C @ 5000rpm 1995 911 Carrera above 5 bar @ 80-90 deg C @ 5000rpm 2001 911 Carrera 5 bar @ 90 deg C @ 5000rpm 2001 911 GT3 6.3 bar @ 90 deg C @ 5000rpm 2008 911 Carrera S 5 bar @ 90 deg C @ 5000rpm Jim |

Perhaps, it means nothing but the GT oil pressure gauge only goes to 10 bar.
I thought that i'd post a couple of pictures from Armando's site of the valve I'm talking about. The p/n is 901.107.017.00. |

I've come across these two Behr oil coolers on Armando's site. The first is a 1970 914/6 GT and the second is a 1973 RSR. Both are only rated at 10 bar, so I have to think that the pressure relief valves should pop-off below 10 bar, not above. At least for this period. I haven't been able to confirm what the pressure rating was on the 1974 RSR oil coolers which had an in-built pressure relief valve.
