Noob Question.. Stock R33 Boost Gauge

[anthony123]

Hey guys,

Sorry to create a thread about this, Ive tried searching but I cant find what I am looking for :S..

Just wanted to know how the stock boost gauge works? what does it read in? as I am looking to put in my Turbotech boost controller in, I want to set it to 10psi.

Cheers

It reads in mmHG (x100)

1 PSI = 51.7 mmHg

1 bar = 750 mmHg

So..... '7' on the stock guage = 700 mmHG which = 0.93 Bar or 13.5 PSI

10 psi would be about a 5 on the stock gauge. Its pretty hard to pinpoint & guessing is not the sort of thing so you want to do with boost pressure so you need to get another boost gauge.

before i ran more then stock boost with an aftermarket boost controller, i installed an aftermarket boost gauge which reads in PSI, cant go wrong mate

if you dont want to do that, the above post is correct

Get an aftermarket one, or do it on a dyno, simple as that.

The stock gauges are generally too inaccurate to be reliable.

Do yourself a favour, and dont trust it or you could find you blow the turbo.
