Good Boost Guage?

^^ Is that a bad guage or just an extremely good deal? (Its the boost guage im looking at)

 

[johng96gst]

Im a big fan of white faced gauges and love my autometer phantom series. Your prefernce, your the one thats got to look at them.

 

[907gs-t]

I run a AutoMeter Lunar Boost 30/30 gauge & it work's flawlessly & look's awesome imo.

A gauge is a gauge, as long as it works & you know how to install it properly it'll be fine. You can buy the best gauge in the world for double the price & install it wrong, get bad readings & blame the gauge.

I personally bought a gauge pillar & 3 gauges off eBay for only $101 shipped to my door & I'm extremely happy with it.

I am a little worried about installation considering ive never ever done any sort of electrical work on my car and i dont want to mess it up, whats the difficulty involved with installation?

installation was pretty simple and straightforward with my prosport at least. i got the green/white one that has a tricky wiring since it changes colors but i only used the white wire so it illuminates white always.

i got an A pillar mount so i grounded the gauge to a screw in that area and then i powered the gauge by extending the power wire into the fuse for my radio, that way it turns on as soon as i put the key in the car like an accessory

Anything that goes up to 30psi
jk I like mine it's a autometer.

I had no idea Megan racing made gauges. Had I know before hand, I would have probably of got those.

I'm currently using an autometer phantom -30+45
I've been through a few different brands, make sure you get something of brand, cheap ones tend to not be calibrated and can cause serious issues later on.

AEM Truboost here, but I have used nothing but autometer's previously. Not fancy, but they work great, have warranty, and there are about a billion different styles.

 

[Blurred Talon]

AEM.
Had Pro Sport but they were junk imo.

Never had a problem with my Prosport

Yes megan is an inaccurate gauge and most companies even high dollar ones are just as inaccurate. I have compared several companies to my map sensor which is dead on and the only one that has even come close was the AEM electronic boost gauge. Some gauges can be +/- 3 psi and that just isn't acceptable to a guy like me.

Well as long as it matches up with the gauge on the compressor and boost leak tester I'm fine with it

That's abold statement considering the amount of gauges that are produced/consumed every day. Support it with facts.

The poster right below you has the right idea...

 

[J_HEATH]

Stewart Warner is nice, Autometer, or AEM. I have the AEM.

stewart warner is only $65 and shows 30psi vacuum and 40psi of boost. You can get an autometer that reads 30psi vacuum and 35psi boost. The AEM is pricey but will read up to 50psi.

That isn't a statement it is proven. Many mechanical gauges are hit or miss and will be slightly off. If you read my post you would have seen that I compared it to a MAP sensor. It makes sense you want to argue the accuracy of a map sensor to a mechanical boost gauge because you are lingering around the newb forum because that is your level of expertise. If you can test your gauge to a reliable source then I highly suggest you do that as the user did and his happened to be spot on for him.

So, no proof but an attempt to belittle?

We have a winner here.

That ProSport not accurate enough for your 370hp? Better warn the potential buyers.

Are you not in the newb forum yourself, belittling a moderator? To say the least it is pretty bold to assume someone's level of expertise by where they "browse a forum". I was about to compare someone's "level of expertise" by their "rep"...but even that is inaccurate on something as punitive as a car forum, so I'm glad I caught myself before I made that mistake.

No proof aahahahahahah. This isn't the court of law where somebody is on death row because of a crime they didn't commit. I have done this test awhile ago and I am not going to take pictures of each individual gauge. Maybe around here you guys think mechanical gauges are accurate but for other folks it is known. They all seem to have a variance. The funny thing too is the gauge that was found to be most inaccurate were Defi's as some have been 5psi off. Am I belittling you? Yeah slightly because you would rather assume testing is better suited from a gauge off of a boost leak tester is a better method than comparing it to a MAP sensor off of your intake manifold. The moral of my comments is to not trust a mechanical boost gauge to be entirely accurate.

His level of "expertise" is easy to glean on EvoM. He caught a warning for the quip. More misinformation without proof will garner another warning.

You make a bold statement like that here, expect to get called on it.

I have a 427awhp thank you very much. I haven't ran that gauge in quite a long time as I have both an AEM boost gauge and a 4 bar map sensor in my car running ecu controlled boost off of a 3 port bcd but out of the handful of gauges I tested I obviously installed the accurate one. The reason it came off of my car is because I have three arm gauges and a prosport just doesn't fit in.

Makes sense actually, in my case I had an AEM mechanical boost gauge that was about 3psi off from, YES, in my case also, a boost leak tester. I ended up selling the gauge and bought a Prosport electronic one and I ended up with a sending unit issue, it would sit and zero until and then shoot up to 15psi after a few seconds of running WOT, then wouldn't settle into the vacuum area. I switched to a Prosport mechanical amber/white and its spot on. I just think it's luck of the draw, even with proven manufacturers making the same products they've been making for years.

I can log my map sensor and my aem together and show you how close they are but I am not able to do that with a mechanical nor do I even have the ones I have tested. I am not here to argue with any of you about the legitimacy of a mechanical gauge. That is for you to test. I am just sharing my experience from a proving testing source. Three more posts and counting till I am out of the newb section.

Even if you tested one gauge from each manufacturer, and all showed a discrepancy, do you not see that as a small sample? Have you never seen a MAP fail?

I'm not disputing YOUR experience (how could I), I'm disputing the bold, broad brushstroke you use to paint mechanical gauges with.

Drop the attitude when you come to our house.

It is absolutely absurd to make a statement like that. EVERY type of measuring device has some inherent error...but the vast majority of quality mechanical boost gauges have accuracies that are well within the needs of 99% of the people on this forum (with a few notable exceptions of course).

I have compared several companies to my map sensor which is dead on

Just out of curiosity, who calibrated your MAP sensor, and how did they do it?

You wouldn't know it if you did.

I'm not sure what that even means, but it was uncalled for nonetheless.

It makes sense you want to argue the accuracy of a map sensor to a mechanical boost gauge

Where did he argue anything? He simply asked you to back up your claims.

...you are lingering around the newb forum because that is your level of expertise.

Or maybe he is in this forum because:

a). He's attempting to help people, or
b). He's a moderator and it's one of his responsibilities.

You're off to a great start here.

 

[Revmoto]

I work at a shop and we pulled all of the gauges off of our shelves and hooked up each individual gauge. I didn't just grab one from each manufacturer and assume that if one was bad then they all are. Also my MAP sensor was calibrated by our ECU guru Mychailo or MrFred on evom.

It isn't absurd to note that any company one buys a gauge from can be off by even 1 psi. It is a warning to double check your boost gauge. Somebody who buys a $200 boost gauge is going to assume it is 100% accurate and they got what they paid for but in my experience even the high dollar gauges tend to be off by as much as 5psi. That 5psi can yield a slow car or a blown motor.
