    On a hot T1 engine with 20W/50 I get about 8-20psi at idle. On very cold days (-3C) it exceeds 104psi on start if I keep my foot on the pedal a bit too long.
    Normally 50-60psi start then 10 psi per 1000rpm running. 26mm oil pump stock unground crank, AS21 case.
    Motorways I keep under 4500 rpm/75 mph But it has hit 5500 rpm once or twice in second gear.
    It has now done 25000 miles like this.

  3. I have the same gauge set for my T1 1956 and the readings are just like that when warm at speed. On idle when warm it drops to 1bar but can be over 4 bar when really cold.
