Out in the Mog on Saturday.
Mine's not a modified engine.
At idle, hot or cold pressure gauge reads around 25 psi, up to about 1200rpm.
Above 1200rpm up to 2000rpm and higher the pressure gradually climbs to a little below 50 psi.
Pressure is very slightly higher on a cold engine (but there is only a tiny difference).

Cheers,
