ive decided to get a new and VERY accurate boost gauge since i dont want to deal with having to get a new autometer one every 6 months.
ive been told VDO, and SPI are the most accurate, but have not heard anything about the OMORI guages as far as accuracy.

i searched previous posts and just found that people said the omori looked close to stock.
i could care less what they look like.....i just want the most accurate mechanical boost gauge available.....what type would that be?

thanks for any feedback y'all can provide

 

You ever get an answer to this?

 

Why does it have to be a mechanical guage?

Most boost gauges are mechanical.

I am not sure which is more acurate for boost gauges, mechanical or electric.

But, I would say the difference is minimal, and the electric is more expensive for sure.

I believe the electronical slightly more accurate. What is nice, is that there is minimal vibration of the needle, aside from what is actually caused by the pressure/vacuum. Each comes with a sensor similar to the MAP sensor.

I really like the Defi gauges, plus the control system that comes with it; you can daisy chain 7 gauges together.

One thing most people don't like is the gauge is currently green lit at night. I don't mind it, actually like the contrast at night. But they are coming out with an amber backlit one very soon.

If you go to the Autometer web site, and go to their FAQ...you will find this under Mechanical vs. Electrical.....

"We receive many questions asking which is better, electrical or mechanical gauges. Both mechanical and electrical gauges are equally accurate. The determining factors more involve installation and application than gauge accuracy. Our new "Full Sweep" electric gauges combine the electric gauge wiring with a full sweep dial face like the mechanical gauge. This short list of advantages should help you to make the decision for your specific application."

My own opinion....(for what it is worth)

So you see, they are probably about the same accuracy. When speaking about gauge accuracy, you have to understand that actually reading the gauge is the most inaccurate factor to take into account.

Most boost gauges read in 1 psi or .25 bar increments (some gauges read in .1 bar increments too). Just looking at the gauge and getting an accurate reading is tough. You could be off by 1psi...or even worse, on a gauge that reads in bar, you could be off .25 bar (3.625 psi), or .1 bar (1.45 psi).

So in general, it is best to get the easiest to read, gauge that has the smallest increments shown on the gauge face. I wouldn't recommend a gauge that reads in bar. They usually don't have enough increments shown on them to be accurate to read.
