How accurate is the Autometer Boost Gauge- take a look
Guys and Gals,
I suspect that my Autometer gauge is wrong ... Take a look and tell me your experience: |
Never seen a model car with a turbo. Sweet! :)
|
The CLK is boosting
|
mine reads fine.
|
you must live below sea-level.

I have an "autogage" boost gauge, supposedly by autometer and it does the same, yet not nearly as bad but towards the vaccum side. I'd honestly change my gauge, that would concern me.

I long while ago I remember a thread about autometer gauges in general being less accurate, and in general a low quality gauge. It's always scared me away from them. But I admit there nicely priced.
|
That does seem pretty off, but it doesn't necessarily mean that the reading is offset by a few psi for the whole range. It would be interesting to see a bunch of gauges connected to the same signal at a range of pressures.

That’s the gayest thing I have ever seen, my Autometer works perfect.
|
i have experienced on several occasions them being wrong autometer is especially notorius for this yours is probably one of the worst i think ive seen
|
i bet if you have it hooked up to a pressure tester, it would read pretty acurate, just the ambient air is off from sea level a little bit.

That happens to the autometer guages all the time, if you send them back they will repair ir for no charge I believe, at least they did for both of mine.

Mine reads about 1/2 pound high ie shows 12, really 11.5.
Compared against PFC |
liquid filled autometer gauges are money! I have seen one and I know it is accurate:)also doesn't the pfc read the boost from the stock sensor (MAP) & the boost gauge hooks up further down the intake track, So couldn't this make for a different reading? I would think so but may be wrong.

I replaced my Autometer with VDO Vision Series. Well vacuum as referenced to a calibrated unit is correct but boost is off by 1 psi. Either the gauge is bad or my plastic tubing connected to silicone hoses back to plastic tubing are leaking somewhere. At least at engine off, it's right on zero.

Originally posted by Rated R1 I don't think it matters if the ambient air is off a little. Remember guages read in psig (guage pressure) not psia (absolute pressure). If it measured absolute pressure the guage would read ~14.7 psi at sea level. Pressure guages measure the delta (difference) between atmospheric pressure and the pressure of the system you are measuring. But, what the hell do I know? I am just a nuclear engineer. |
I'm with Gordon, my experince with Autometer has always been good. People get the 15 dollar Boost Gauge and think it's going to perform like a $250 Defi gauge :wtf: Go get their nice one with peak boost memory and overboost warning and resets to the current pressure of where ever you are. Not like any other gauge that it measures 0 at 14.7 PSI, the Autometer resets to zero every time you turn your car on... Any other gauges you know do that???
|
Oops, didn't notice that this has already been said. My bad.
|
I have had no problems with the Autometer boost guage.
|
My autometer boost gauge reads identical to what the haltech tells me. Only time that it reads off is when i'm decelerating and the vacume is reading 22 on the autometer and 25 from the haltech.

LOL!!![/SIZE]

Originally posted by setzep Well if you want to get into it that far the gauge does sort of read psia, it's just the display reads in different values. 30" of mercury could be taken as 0psia and the "resting point" of the gauge could be taken as what the pressure really is outside. So if the gauge read a tad below or a tad higher than "0" on the dial it could be because where they live. But what do I know I'm just a fluid power specialist. ;) -Max |
I was just saying in a way it is a psia gauge. If you redid the #'s on the dial to make 30" read 0 and 0 read 14.7 then it would be a psia gauge.
Why woulden't the needle move down if you increased your altitude? If you put that gauge on the outside of a jet @ 35000' your saying it would still read "0"? :confused: |
