std boost gauge conversions

[Pekatu]

does anyone know what the conversion from mm/hg (millimeters of mercury or what ever) to PSI or BAR is.

there is a post at the moment where a guy is saying that 7mm/hg is about 14 PSI but i don't think so cause my 32 needle sits just on +7 and it does not have a bleed valve or boost control.

thank you.

Heres a good site converts everything to everything..i use it very accurate no problems

"just on" could cover a spread of around 2-4psi, it's not so much your gauge is inaccurate it's more that the scale is inadequate....not enough resolution

the +7 indicates 700mmHg =aprox 13.5psi= aprox 0.93Bar.

My apologies my origional post was aprox 1.1psi in error

760mm HG = 1 atm = 14.69 psi = 101.325 kPa = 1.01325 Bar

Use the google calculator

cool thanks guys assuming 'just on' is no less than 4 and no more than 5 it is sitting between 7.7-9.6psi or 0.533-0.666bar. is this normal for an R32 with no mods?

Yes

dudez i thought the +7 was 0.7 bar which is about 10psi. mentioned above was 14psi, this cant be right cauz 1 bar is about 14.9psi.

there is no way factory boost is 14psi. as far as my knowlegde goez the ceramic wheel cant handle this figure for too long on hard driving.

correct me if im wrong ppl.

nah man it say's on the dial X100 mm/hg that is millemeters of mercury @ 0 deg.

check out the conversion site listed above.

mine sits on +7 now after doing an air box job, i have a big hks super dragger exhaust, and hks blow off and yer, my friend fiddled with it, but i dont think he changed the boost, think its just gone up with the huge air flow increase
