What pressure should my gauge read tick over and driving 4x4 cosworth

 

thy can varey,depending upon engine condition.
Mine reads 4bar on tickover,and 7.5 when driving at a constant speed.Thats a 2wd ,but shouldnt be much diferent to 4by

 

any thing around 30 psi on idea is fine i think m8

 

As above, around 30 psi at idle is about the norm when hot. 4 bar at idle when hot Jesus would say thats a bit high

Simon.

 

4 bar ridiculously high and 7.5 bar when driving stupid using a lot of power to run pump, does not need anything like this pressure.
Hot idle of 1 1/2 bar normal and ok 3 bar when driving minimum 4 bar better.

ps most likely an inaccurate guage at 7.5 bar

 

Could it be an uprated pump then?

 

Oil grade is also a factor



7.5 bar Thats 110 psi

An uprated pump is usually 80 psi on throttle so maybe your gauge is faulty


Mine is 55psi when start up, and 20 psi when cooked

Ive been told and reasured that this is the "normal" type of oil pressure so im happy

 

what about on a 2.1 zvh escort rst. thanks

 

Could be an uprated pump but this is ridiculous pressure and not needed, it may well airate the oil and lose wedge because of this, it also uses power to run.
As said 20 PSI hot and 60 PSI running above 2500 perfectly fine .

Engine is a fresh rebuild ,now got 2.5k on it and my guage reads 4bar and nearly 7 at revs .
Pump is new too.
If its to high i am sure my engine builder would have said so and corrected it
i wont even bother to ask him

 

i have a high pressure pump.

i see 70 psi at cold start and 25- 30 psi at hot idle

 

It is most likely just a inaccurate guage.

same here

 

80 when starting up , and 35-45 roughly when hot and idleing

On full chat it hits 80
