Boost gauge issue...

[TTT]

On my car..(92 Skyline R32 GTST)

The stock boost gauge in the dash shows...

+7

0

-7

I've also got an Autometer boost gauge in the car..

MY question and concern is as follows..

Question.

Where does the Standard boost gauge get it's reading from?

Concern.

On full throttle in say 2nd gear at about 5500rpm the autometer gauge shows that I am hitting about 10.5 - 11psi boost.

The stockie gauge doesn't even reach the +7..

WTF??

Which one is right?

I'm not sure where the autometer gauge is connected (haven't had the car for that long and haven't spent time looking around).

The only engine mods are BOV and K&N pod filter..

Exhaust is standard.

has anyone else noticed this in there skylines?

The standard gauge isn't in psi. Ignore this and work off the autometer one for psi readings. Inside the engine bay in the back drivers side corner is a small plastic box attached to the firewall with a vac line coming out. This is where the stock gauge gets its signal.

Thats a lot of boost for stock, i'd check the actuator line for chacks

[jethead98]

The standard boost guage is calibrated in mm HG (millimetres of Mercury) ie 760mmHg = 14.6 psi = 1 Bar

0 Guage = 00.0 Psi

1/4 = 3.36 psi

1/2 = 6.72 psi

3/4 = 9.10 psi

Full 7 = 13.4 psi

Hope this helps
