kg/cm2 boost gauge?
I've looked at the conversion factors but I'm not what you would call...good at math.
I bought the car with Greddy boost/vacuum (kg/cm2 and mmHg) and oil temp gauges (Cel).
I got the C to F conversions down, but can't seem to comprehend the boost. Can someone simplify this for me or point me in the right direction please?

The way I normally think about it -
.7 = 10psi
.8 = 12psi
.9 = 13psi
1.0 = 14.5 psi
These aren't totally dead on the numbers, but they get you thinking properly. Stock car should see a max of .7 or so, with a dip for transition of course.

A healty stock engine has good vacuum at idle.
Divide mm-hg by 25.4 for the common in-hg units.
500mmhg = 19.68 " vac
400mmhg = 15.75 " vac
450 would be excellent at about 18"
400 a little low
