Hi ... what sort of oil pressure should I expect in at Cosworth engine running a HP oil pump, 15 50 oil at idle Cold and hot... ?

As it is Ive been running a mechanical gauge showing 85-90 psi Cold and 33-35 psi hot .. both at idle.

Now I have put in a 10 bar vdo sensor with a el. gauge and its showing 69-70 psi Cold and 23,8-18,6 psi hot .. witch I feel is a bit low .. or ?

please advice .. ?

 

your mechanical gauge would have been reading about right for a decent motor

just had a similar thing myself today-had an electrical gauge-about 65/70psi cold idle etc-changed the gauge but kept the existing sensor now it shows just above 2 bar at idle -looks like i need to get the correct electrical sender to sort it out...

 

your 10 bar sensor is too much for your 100 psi gauge

10 bar = 145 psi

 

Yes the gauge always needs to be fitted as a matched pair with the sensor.

 

well the sensor is in the kit .., IECS monitor and should be a VDO 10 bar sensor so I take that it is ok

 

with my new gauge now married to its correct sender my oil pressure is just under 6 bar at cold idle[fresh 200 series engine]

 

Hmm .. ok .. I'll try to get my hands on another press. sender.. and see if it will change it to the better ,,

 

after 15mins fast road driving using plenty of boost [stage 3 car] oil pressure at idle is 4 bar[fresh 15/50 titan r just today] standard oil system
oil gauge and sender are racetech latest model
