can anybody clear up the confusion about the turbo needle on a GTST....
on my car it goes between +7 to -7 and the units are x100mmhg...to me that means when the needle is at +7 it means 700mmhg which is atmospheric pressure or in lay mans terms the air we breathe.
can anybody shed light on the subject???:smoker:

AFAIK it means 700mmhg above atmospheric pressure. Its the same thing with an aftermarket boost gauge reading in BAR. When a turbo is making 1 BAR it is actually making 1 BAR above atmospheric pressure (1 BAR) so in theory its making 2 BAR if that makes sense.

that makes sense dave....which means 0 on the display = half bar....they didnt half try to confuse us
anyhow gonna be getting Defi's soon ...
also am i correct in saying the oil pressure units ...kgcm2=bar
i think im right....1 bar = 1.02kg/cm2

thanks
