Boost (PSI) Gauge

[HuGo]

What would guys recommend for a good PSI gauge? Since im ordering the dasc on monday, i want to order the gauge as well. I seen some gauges with VAC on one side. What does VAC (assuming Vacuum) read? And is the press meaning the psi? All i really want is just a gauge that tells me PSI.

which of these 2 is better?

Think this is good enough? I dont need why i need a number that reads up to 35 if im only gonna have 8psi. Do they sell any gauges that show only up to 10 psi?

Get an AutoMeter boost gauge. Vacuum is good to see also.

How much PSI 0-30 or 0-35? And what am i looking for when looking at Vacuum, how do i read that? Like the numbers, what am i looking for cuz i have no idea what would be good or bad or whats going on.

Since you are only going to run 7.5psi, you don't really need a 35psi gauge, right? I think this would be a lot easier for you if you understood what a supercharger did, or how an engine works.

Did you read the Corky Bell book yet?

So your about to put a expensive upgrade on an expensive engine and you really should spend some quality time researching the whole story. Things go badly in a big way in a hurry with too much boost and not enough understanding of results. You don't see all the blown engines the Honda/Japanes Marques create in the magazines, only the success stories...

Be cautious...

Agreed...it's very important to understand what you are doing.

Why go with autometer, greddy, or any of the others when you can get a good cheap gage that fits in perfectly with the interior of your car.. and only reads to 15psi?

VDO makes such a gage. Availible in both Cockpit (traditional side lighting) and Vision (through gage lighting, like stock) that read to 15psi and are really cheap to buy new, and even cheaper to buy on ebay. Good quality, accurate mechanism, and matches the interior.

That is an electrical gauge which means it requires an additional sending unit. There are lots of gauges out there, I've always been impressed with AutoMeter quality and design, that's why I recommended it. It's nice to have a gauge that also reads vacuum so you can diagnosis a vacuum leak. This is what I have:

ok so autometer 0-30psi. And a good read on vacuum is 10-15 right? Will look for one.

[HuGo]

so when in idle it goes to vacuum and when your in gears it turns to the psi side?

No more help until you read "Supercharged!" by Corky Bell. You can buy it on Amazon.

Ill just visit boarders and sit down and read it for a while.

I bought my gauge. 65 bucks oh well. Atleast ill know if im losing boost. This is the one i purchased. Its 2 1/16 inches.






Now, this gauge is pretty long and i have no idea where i would even place it





I want to place my gauge right behind the cigarette lighter, that little whole to put stuff.



But the gauge itself fits in there but the back part is long. And the screws in the back do not unscrew (circles in red). So it will be popping out a little. I really want to put it there but i wouldnt know how. I would have to cut out a big hole to put it in. Or maybe not cut the hole but how would i be able to put it in place.
