I'm looking to buy Oil Temp, Oil Pressure, and Water Temp guages for my S5 n/a, I was qurious what sweet for the needle do I need to buy?

I am looking at the Autometer Ultra-lite series, and they have these guages in 3 diff sweep veriations. Their relative price to each other is not an issue, I just need to know which will give me the best accuracy for the temp and pressure range my car will spend most of its time in.

Thanks

 

I would get one with a 270 degree sweep.

 

In the ULTRA LIGHT series The MECHANICAL guages are 270deg sweep, and the ELECTRONIC ones are 90deg, Autometer is adding some "FULL" (270deg) sweep electronic guages but I don't think any of them are in the ultra lite series.

 

So....Are the 90 deg good enough for my application? OR should I look into the Full sweep ones?

 

My personal pref is to use Mechanical Guages for PRESSURE and ELECTRONIC For Temprature - For a Rotary, the OIL pressure Guage needs to read to at LEAST 120psi - the only AUTOMETER Oil Press guage that goes over 100psi is Mechanical (0-150psi).
Also the Presure guage moves through a Wide range and varise quickly with changes in RPM., so a LONGER sweep is more important, the TEMP guages operate over a smaller range and the rate of change is slower so a Shorter sweep is OK.

 

Wow...when would I ever see 120-150psi with Oil pressure. I thought it would be more around 30-60psi?
Dont forget, my car is a '91 N/a w/ street port.

 

bump...someone - please...somebody must know
