PlasticStan Posted January 27, 2006 Share Posted January 27, 2006 My Greddy gauge shows just under -500mmHg which is -9.7 psi or -0.67 bar. Link to comment https://www.sau.com.au/forums/topic/103539-vac-presure/#findComment-1904258 Share on other sites More sharing options...
BHDave Posted January 27, 2006 Share Posted January 27, 2006 I get anywhere between 19 and 16 (when the air con is on). All gauges will read a little differently but as long as you are around there somewhere you're right.
