lol i realy wanted to put two guages on my a pillar....but i dont have anything running on my car that would require it. I was thinking running air and fuel pressure guages, but whats the point? lol i feel like such a ricer
Nitrous pressure and fuel pressure are a MUST! You don't need to have anything serious to put gauges on your A pillar. Stock does not have a fuel pressure gauge and it always nice to see your fuel pressure.
I did water temp and oil pressure when I did my headswap just to be cautious. Since it was such a big investment I want to be able to catch a problem before it causes damage.
theres still good things you can add to a stock car-
oil psi - the stock oil psi gauge is UP at 8lbs, dead at 7. its a 'switch' gauge. (gay)
trans temp - a MUST for auto guys.
water temp - the stock water temp isnt quite that bad, but its not anywhere near exact.
fuel pressure - a nice thing to know as there is no stock gauge.
and definitely get all electric. mechanical gauges arent any more accurate and are far more hazardous.
