yea yea i know they are autozone specials but are they accurate?

Smirnoff · September 30th, 2008, 02:41 PM

if you have the money buy some better ones

nolife · September 30th, 2008, 03:08 PM

Either way, I'm sure they are more accurate then the factory gauges and sending units on most cars. For about $15 a gauge, it's worth trying. If not for very specific number readings, at least you can spot trends.

They have been around since the muscle car era so they can't be that bad

awsome thanx guys, ive got an autometer tach in my shed but im pretty sure it doesnt work ne more

Hunt_chevs · September 30th, 2008, 05:09 PM

do they make an inexpensive air/fuel?

Matt Cramer · October 1st, 2008, 08:37 AM

Yes, they do. Just keep in mind that the cheap air/fuel gauges that run off the stock O2 sensor are never very accurate. The stock O2 sensors are optimized for emissions purposes and are great at telling you if you're precisely at 14.7:1, richer, or leaner. But they don't do a very good job at telling you how much richer or leaner you are.

I think the accuracy is probably ok with Sunpro. I think the cheaper price is more relative to how ugly they look.

im just saying this because i tried sunpro guages and the voltmeter shorted out on me and blew a fuse or two and i dont really trust my oil press. guage either

For what it is worth, I bought a mechancal SunPro oil pressure gauge to monitor my 5.8 Bronco (the stock gauge on that is worse then the one on the Mustang). I checked it full sweep with air with my air compressor and it tracked dead on. I don't know if that is a valid test or not though.
