Hi everyone.
Last night was with a mate and we were having a silly play fight over PSI and BAR boost gauges, he uses a gauge in bar and always refers to his car in bar, where as i used a psi gauge and refer to my car in psi.
So what does everyone else use, this is just out of curiosity. In my mind psi something more real, pounds per square inch. Bar?, what a chocolate bar?!lol

 

I've used both before now and have a BAR one in the cossie.

Scale is -1 to +2 bar and it reads off the scale in both directions

If you're technically minded then you can easily change between BAR and PSI mid conversation and still know what the numbers mean


PS - 2.2 bar FTW

 

From MY experience i always preferred psi in my rst as it was sometimes wanky little numbers of 10 psi which looks on a 2 bar gauge.

When i grew up and got a cossie i've had bar ever since

 

I'm quite technically mind, but i dont know how to convert psi to bar. I am an odd person, il do one thing in old money and another thing in metric! bit like my work bench i built myself, as i did it over two day, half of it was measured in inches and the other half in mm, so its got a lil bit of lean going on!lol

In my stupidity what is a BAR?

 

14.5psi = 1 bar

 

I prefer psi myself as i'm only running around 1bar so i find being able to see the actual psi more useful.

 

Got both on my secs monitor but use psi.

 

CheeRs bud.

 

I prefer PSI myself.

 

lol
Top class reply bud.

 

14.5038 psi = 1 bar
to convert psi to bar, psi X 0.06895 = bar
tabetha

 

Your gauge must be wrong then, if it reads over 1 bar vacuum, even on overun.

Cant be that wrong as my PSI gauge will drop down to -16psi on vac on shut off.

 

I doubt it is wrong - compared to the PSI gauge that was there before it is accurate (and that has been tested with a calibarated air supply etc etc)


It was easier to say it reads both sides of the scale for comparison instead of being too detailed
