How much boost pressure does the 440 turbo run as standardand what psi/bar does the standard boost gauge read up to
thanks in advance

I don't know what boost pressure that car runs but I will bet anywhere from 5-10PSI.

As far as a standard boost gauge what do you mean? Like does the 440 have a stock boost gauge or do you mean like an Autometer boost gauge?

Most boost gauges are 25 In Hg/25PSI, 30 In Hg/30PSI, 30 In Hg/25PSI.

In Hg is vaccum and PSI is the boost.

the 440 has a stock boost guage but there is no figures around the dial, just colours (green, amber, red) just wondering if anyone would know in psi or bar what this guage reads as a maximum
thanks
