    Most accurate gauges

    Who makes a good one? Can someone point me to some actual testing, not just marketing hype.

    I've got some SAGA that I'm running in my wagon now. I trust them. But Sometimes I'll get low oil pressure beeps at hot idle. A mechanical gauge tells me it's fine and I've got 10psi.
    These are very similar to defi.

    I'm using AutoMeter mechanical in the 86.
    I tested my oil and water temp in boiling water before I installed them... Not only did they not read ~212deg like they should (well, 205 in calgary), they didn't even match each other! iirc 5-10deg off, something like that. I installed them anyway. What a joke though.

    A buddy at work was asking what was good...I told him I don't really know, and to buy Japanese probably lol.

    Stick the temp gauges in boiling water and see what you get.

    In the water is lower than boiling. The boiling temp is actually the stream/non liquid moisture temp.

    iirc

    In my experience most jdm companies ect all use the same parts. Same sendors ect. Shouldn't they read 100C though at boiling? Double check with meat thermometer aybe?

    the only really accurate gauges ive found are industrial items, for generic pressure, temp, etc. good gauges will be calibrated and will offer an accuracy range (+\- 1psig etc). prob cost a lot more. hit up a hydraulics or industrial supply store.

    also 2 friends with the same gauges have oil beep issues at idle when their motors are hot. same deal, false alarm.

    In Toyota, we rust.

    10psi oil pressure is too low, maybe try a thicker oil?

    Not true. Boiling water will be exactly 100*C/212.*F (at sea level) any lower and the water won't be boiling, any hotter and it will be steam.

    I think the confusion is coming from misremembering "heat of vaporization", whichis the amount of energy required to change a liquid into a gas. It's just the energy required top change state.

    IS 5-10 degrees on a temp guage really make or break? It will still tell you if you are running hotter/cooler than you feel safe with, no?

    Running an oil cooler too? Fack.

    Also, do you sell just the shock tower bolt on rings for your strut tower bars? I want to make a custom setup for my TE.

    Meh. I've seen temps over 270F at the track, not a problem with synthetics
