which are terribly innacurate and inconsistent. i remember once i could smell my engine cooking during a fairly spirited hills run, so i backed off not knowing what was going on, about 20seconds lately my water temp gauge shot up to the high reading over about 3 seconds (real handy, lucky i have the nose of a dog lol). not to mention in the morning it will go from stone cold to opertation temperature within 10-20 seconds, even after a few minutes of driving.
then we get to oil pressure, lol, basically i havnt been able to drive my car for a few weeks now as the gauge is f**ked and i cant get a proper reading, and since i have a few problems related to oil pressure at the moment i do not feel confident driving it without a proper reading of oil pressure.
so then we get to the boost gauge, well i think we can all say without doubt that it is a POS and doesnt even read to what most of us boost our cars to anyway. i am about to install a bleed valve along with a new turbo, so i will need acurate readings to set my bleed valve at the right level.
i actually made a mistake, its a oil temp gauge, not a boost gauge included in that $300.
the oil temp isnt as important, but there is still lag between oil temp and water temp so its a good reading to know.
also i saw these, they have stepping motors etc and seem to be relatively cheap, but they are autogauge so im weary.
