EGT=1600
Fuel pressure= i think they go from 100-150 or something in that range.

boost=if you can find 0-15 or a 0-20. when you get a 0-30 itll be too small to tell what you are boosting....or you can get an EBC and not worry about a boost gauge.

All of my gauges are 52mm White Faced Gauges. Currrently I have Fuel Pessure (which reads in BAR, similar to boost because its pressure), EGT (which reads in Celius, s 0-900 degrees), and Boost, but its not hooked up yet, but it will also read in BAR. All of these gauges match the stock gauge color beatifully, which of course is green. But, these gauges have a green needle, not red like your looking for. I *think that Apexi makes a black faced gauge with a red needle, if I remember correctly.

If you heard bad things about Autogage, I'd be more likely to agree. Autometer makes the inexpensive Autogage line, but they aren't as accurate or as durable as the Autometer.

I've been looking for a decent boost gauge that measures below 15psi... but there just are not may to choose from at all. If I'm only going to be running 0-6psi of boost, what good is a 0-35psi gauge?

So...

I am about to place an order to Dakota Digital http://www.dakotadigital.com for their Boost, EGT, and Fuel Pressure gauges. They are not quite as sexy as the white faced autometer gauges, but more importantly, they do exactly what I want... They give me an EXACT boost pressure reading for a low boost (0-6) application. I sent an e-mail to them asking about the boost resolution.. This is what they said.

Hello Shane,
Our boost gauge ODYR-09-1 will be accurate from 0.6 - 30.0 psi. At boost pressures below 0.6 psi the gauge will read 0.0. The accuracy does not change between 0.6 psi and 30 psi.
One other nice little feature that I found out about with these gauges, is they come with a WARNING level setting. Meaing, I can set my EGT gauge to warn me if it exceeds some value.. Like 1700F. Or if I get a boost spike. :)

A dash full of those Dakota Digitals would look real nice, but they don't seem to be the easiest to get the information from. Glancing at the tach seems way quicker then reading the number from the tach, but maybe thats just me.

Yeah, I agree with ya there. I would not want a digital Tach or Speedo... They flop around too fast, I want to see the needle move.. But for a Boost, EGT, and Fuel pressure, I think digital will be just fine for me. The EGT and Fuel Pressure don't fly around enough to make it hard to watch in Digital.. and as for the Boost pressure... well, I want accuracy at low numbers, so I'm willing to go Digital for that.

will a digital gauge necessarily be more accurate at low psi... won't it depend on the entire unit.... lines, and hoses....

my Autometer guage and SBC-id disagree but 2-3 psi... at low and high...

If you have a peek at my earlier post, you'll see a quote from the guy at Dakota (granted, he wants to sell units, but I doubt he'd flat out lie). He sais that the digital units are accurate from 0.6psi, all the way to 30psi.. I think I remember reading in the install manual that the sending unit has a resolution of 0.6psi or something like that. So I'd say that for low boost application, these digital gauges are better an analog gauges. If it reads 2psi, then it is is likely somewhere betwen 1.7 and 2.3psi or so.. Where as the Autometer gauges, the needle is just a hair past 0psi, because the scale is 0-30.

Ok, I'll stop rambling now.. I think you get my point.
