I think this belongs here...please move to interior if its wrong.

Reguarding how boost gauges read, which one is more universal or usable?

I'd have to say i think psi is more accurate but i see that JDM is in bars?
Can someone convince me that psi is better then bars? I want bars because it seems like no one has it and its JDM :lol:. The psi is easier to find and seem more accurate though.

Get PSI, BAR would be useless, unless of course you are just getting the gauge for bling. Then, do whatever 1337 thing your heart desires.

Most people prefer PSI because that's what they know. Its what they can relate to when they read all the american magazines and read all the stats.

One isn't more accurate than the other - its just a unit of measurement. Its like saying centimetres are more accurate than inches.

I like psi, myself. Easier to refer to 14 or 15 psi instead of 0.96 or 1.03 bar.

Yeah I asked my dad the other day how much psi the porsche was boosting at, he referred to it in bars. Retroooo

Our stock boost gauges are actually in MPa, not bars unless you went aftermarket... Megapascals?? Yeah, I'd go with Psi if I was going to buy another one.

Pascals is the SI unit, so Subaru got it right, everything else is non-standard ;).

I went PSI cause i am to lazy to do the conversion. But I think it's all the same.

MPa FTW!!! Ricers have not idea what the hell MPa is. :lol:

They ask about what boost I'm running and I tell them .1 MPa and the look on their face is PRICELESS. :lol:

get what you're most comfortable with and is most useful to you. if you don't understand what a "bar" is or represents, go w/ psi. a gauge is useless if you don't know what it's telling you.

Centimeters are not more accurate than inches, but it is fair to say, since there are 2.54 centimeters per inch, that measurements expressed in cm tend to be more precise than measurements expressed in inches.

I dunno but the stock Porsche boost gauges (the one in the trip computer right under the tach on 996+) also read in bar, rather than PSI.

Correct about the stock gauge. I wish I had gone the aftermarket route now, as PSI is a definite convenience to read.

accurate=correct. precise=number of decimals.
Lets say we have a number 6.
it is accurate to say that the number is 6. it is precise to say that it is 6.00000
It is precise, but inaccurate, to say that the number is 5.00005
it is precise and accurate to say that the number is 6.00000000000000 etc
see?
(and a common mistake is using more precision than is possible/available/accurate, for example measuring the above 6.0000000 inches using a yardstick.)

Fellas, I wasn't debating the semantics of using accurate vs precise.

My original :confused: :confused: :confused: was directed that somehow inches are more "precise" than centimeters.

The guy was basically saying that because 2.54 centimeters is 1 inch, that the unit of centimeters is more precise when he said this:
that measurements expressed in cm tend to be more precise than measurements expressed in inches.
Well the opposite can be said for inches, because 1 "imprecise" centimeter = a more precise 0.393700787 inches. By his logic, now the inch unit is more precise.

I just found that funny, thats all.

Now back to the BAR vs PSI vs MPa argument. I'm sure that if all the Subaru, Cobb, UTEC, whatever documentation expressed everything in MPa, then we'd be loving our stock boost gauge (assuming it was ACCURATE). But because the unit of MPa is foreign to most of us, we don't like the gauge. Just like if our speedometers for some reason came in FT/SEC instead of MPH. We'd be pretty anxious to swap that thing out wouldn't we??
