Ok, say you have a 2.25 bar map sensor. How many pounds of boost or pressure can it handle? Explain how you reached your results. I say its 2.25x14.5=32lbs.
My buddy says 18lbs. Not sure how he gets his results.

 

i don't know what it is but i know the answer is something weird, 18 actually sounds right. im pretty sure that it doesn't work out w/ straight math. but then again im not a reliable source for this, good luck.

 

huh? thats retarded.

A 'bar' is just a unit of measurement, just like psi.

If you have a 1bar sensor, you will read to atmospheric pressure, or about 14.5psi. This is for N/a applications since intake pressure will never exceed atmopheric pressure.

a 2.25 bar will read 1.25 bar *over* atmospheric pressure, or about 18psi of boost.

You lose homeboy.
