PostSubject: Oil pressure   Tue Jun 14 2011, 22:11

Just wondering what is a good oil pressure reading to get from my engine. I'm running a kr engine on zx9r bike carbs. I've installed a fuel pressure gauge in the car and I've put the sender on one of the switches on top of the oil filter. When cold it's reading 75psi, but as soon as the temperature gets up to around 90 degrees it drops to around 15-20 psi on idle and goes up to 45-50 psi when revving.
Just basically checking to see if these figures are ok. Any help or input would be great Smile

At temperature the oil pressure should read 2(ish) bar at tick over rising as the revs do to a max of about 5-6 but dont take this as set in stone.

Taking 1 bar as 14 psi your pressure is a little low but not too far out fo ran older engine.
A new pump (easy job), filter and oil will (should) help this.

Where did you read the pressure from as it should be taken at the pump (oil cooler) .

The pressure reading come from on top of the oil cooler. It's just had an oil change and the engine is rebuilt so it shouldn't be to do with that.
I've got a 19 row oil cooler sat around from my old car, I'm wondering if I could use that to keep the oil temp down, in hope that it keeps the pressure a bit higher? Or is the standard water oil cooler sufficient?

Running an oil cooler will drop the pressure once the thermostat opens ;-(

Oil coolers are a little bone of contention of mine.

Unless you have it on the track and ragging the living bejeus out of it I dont think you even need the standard oil cooler as it is, but that said I wouldn't fit itas it'll drop your pressure further.

I dont think the pressure is dangerously low, just keep an eye on it.

Ha ha I've taken the golf to 1 side and promised it that I will look after it a bit better than last time.

It's all lies of course Twisted Evil

On a serious note, I will just keep a check on it and see how it goes. Can you get higher pressure oil pumps for the kr, because at worst I will just fit one of them further down the line.

Cheers for the help and advice ;-)

Need to pull my finger out and get it booked in for a rolling road session Smile
