Vacuum, I believe. Correct me if I'm wrong, anybody.
How to install a boost gauge in a acura integra?"
vac stands for AC voltage
A boost gauge in an internal combustion engine has the role of a pressure gauge. The gauge indicates the manifold's air pressure or a turbocharger or supercharger's boost pressure.
the normal boost is 5-12 psi. the normal vac is about 18-20 psi
To increase a 4.5 VAC supply to 5.5 VAC, use a transformer. To increase a 4.5 VDC supply to 5.5 VDC, you'd need a boost converter.
It can stand for a lot of things, i.e. 57 Hydro Vac, 57 Heinz Varities...
One can purchase a boost meter or gauge from Jegs and Glow Shift Direct. These meters can also be bought at Treadstone Performance, Egauges and Sunmit Racing.
probably a vac. leak check your brake booster
400 vac stands for 400 volts alternating current. It indicates the voltage level of an electrical system that delivers alternating current power.
either because your not running enough boost or your a moron
kilopascal gauge
boost pressure, as you call it, will not show on gauge,if you have one, while engine is at idle the turbo pressure does not boost but runs all the time according to the revs of engine
