Does anyone know the output of the oil pump on imprezas in pressure and flow?

 

9 gallons a minute is the flow stated by Dave from API on another thread.

 

From a copy of an 04STi manual that I have as follows.

600rpm 14psi 4.6 l/min at 80 degC
5000rpm 43psi 47 l/min at 80 degC
Oil light switch set at 2.1psi

Although this is whats stated in the manual I get 33psi at 750rpm idle and 90psi at 5000rpm, being a positive displacement pump I think the flows strated can be believed but the discharge pressure must depend on the state of the engine.

 

thanks for that lads
