Does anybody have a Digital Readout Boost Guage? Pr?o's/Con's
 

I was looking in my summit racing catalog and they have a Digital readout boost guage in PSI .. that goes from 0-16 PSI. Thats about perfect. And it looks really cool, anyone know how accurate they are? Anyone use a digital readout boost gusge on there 7 right now? Input please.

Most digital gauges can't respond fast enough - an analog gauge can always give faster feedback.

BTW, there are a few Greddy boost gauges on Ebay right now :).

Digital gauges shouldn't be used for readings that change very rapidly, because the human brain easily can't work out how fast the value is changing. Readings like temp and voltage are ideal for digital gauges, but ones like boost and rpm aren't. You need to be able to react quickly if they go too high, which is much easier to predict watching a needle sweep past a scale.

Right on, Thx for the info. I have a Autometer gauge ... but I have not even opened the box yet. I have heard mostly all negative about them so I am going to return it and get a better one. What is the differance between a mechanical & electrical one? Pro's & Con's .. and a good recomendation for a quality boost guage under $250?

Defi makes a good gauge in psi go to the mazda store website they have good selection

I'm putting a SPA digital boost gauge in my FC, but I have not tried it yet. I am interested to see how it works in a car.

I disagree. Sometimes an analog gauge will respond slower due to mechanical play in the system. However, the lag will create a damping effect which may be desirable. Some digital gauges have user-defined damping for this reason.

Needles are better for showing a trend, digital displays are better for showing a value, and a warning light is better for showing a limit. Personally, I'm more concerned about the warning in this case. Datalogging or max-value recall functions are also quite handy.

Other issues:
Mechanical: Doesn't require electricity to operate.
Digital: Generally easier to route the sending unit, and generally easier to calibrate.

I think it all comes down to what you are most comfortable with.

get the greddy electronic boost gauge.
