Oil Pressure 1.6 K-Series
Discussion
My Stack reads 10psi under - I get 51psi onm track at high revs, which when measured with a mechanical gauge is 61psi.
The electrical senders are where the fault lies - possibly an incompatible curve to the response characteristics of the gauge - i.e on a car with normal gauges a Bosch or VDO sender but Caerbont gauge.

I wonder why so much store is put in to the accuracy of mechanical gauges?
30psi hot idle OP in a K is cloud-cuckoo land.
Bert
How do you figure? That's the reading both on the fitted mech gauge and a remote (garage equipment) mech gauge. 30psi hot idle OP in a K is cloud-cuckoo land.
Bert
You should be getting 2Bar (28PSI) as a healthy hot idle pressure and around 4Bar (58PSI) at 3000RPM.
The reason I say the electrical gauge was crap was because it was never consistent in comparison to the mech gauges.

my oil pressure electrical gauge 1.8 k series has always read low but I was horrified to see the needle reading under the red line at hot idle today. My logic says when I turn the ignition on engine not running the needle should be at 0 but its below zero. My gauge is 0 to 8 bar but I never see more than two bar.
so should I go to a mechanical gauge or just try a new sender, is there a mechanical gauge that matches, the dash set I have?

A mechanical setup can be had for roughly the same price as a new electrical sender. I'm go mech.so should I go to a mechanical gauge or just try a new sender, is there a mechanical gauge that matches, the dash set I have?

I'm a fan of the mech gauge, I believe they're more accurate and, just as importantly, consistent. so should I go to a mechanical gauge or just try a new sender, is there a mechanical gauge that matches, the dash set I have?
I bought my set up through Merlin Motorsport but it's the same as the equipment supplied by Think Automotive, £58 all in, cheap for peace of mind. Took about an hour to fit from start to finish.
The gauge is Mocal and whilst it doesn't match the CATERHAM gauges perfectly it certainly doesn't look out of place.
I've got a very new (less than 300 miles) CATERHAM sender and a couple of gauges for sale - if you're interested in them PM me.
I sourced all the plumbing bits from Think Auto but used a Stack mechanical gauge .... I've been so impressed I've fitted a Stack temperature gauge (electrical) to match. The Stack gauges are extremely clear to read and the illumination at night is near perfect.
Big plus of the mechanical oil gauge is the 270 deg needle sweep compared to only 90 deg on the electrical gauge, the matching temp gauge is also 270 degs.

.... I can't remember although I'm sure I have the paperwork somewhere!
If you speak to Matthew at Think Auto he should already know what's needed. Also it's better to buy 2 hoses (one only around 30cm) made up to fit a boss in the middle to take a low pressure switch. Even if you don't have one now you're making it ready to easily add a low pressure warning light in the future.
