going to be buying a Z this weekend,

 

i already have GReddy boost Gauge from my last car.

 

do people have 2 gauges as its twin turbo?

 

or is there a location that will say what the cars producing.

 

if the 2 turbos are on 10PSI each, will the gauge read 20PSI?

 

little confused as to how it works

Pretty sure you just need the one gauge pal :)

You could have two gauges if you wanted, but as the two sides of the plenum, and hence the output from the turbos, is linked, then it is of limited use.

No, 10psi + 10psi does not equal 20psi :)

 

Use your Greddy boost gauge and connect it to a convenient place on the balance bar. In that place it should take an average of both turbos output.

thanks dudes,

 

il wait til i get the car, then have a look about installing it.

 

il do a search on here also :)
