boost/vac guage

[fasteclipse1992]

will a boost/vac guage work for reading turbo boost? or just a strictly boost guage be better?

I don't know of any boost gauges that don't also read vacuum. Though I'm sure there are some out there.

yes, you want both, vac is useful too, and yes there are some that dont have vac.

There are many Boost guages that do not read boost... I highly recommend getting a guage with Vacum - this way you can know atleast one more aspect of your engine... And if your car isn't running right, the vacum guage 'may' help you diagnois a problem (ie: Boost leak)...

No real difference, they're just Bourdon-tube gauges. A boost/vac gauge may not sit exactly on zero when off, but a pure boost gauge will have a post to make you _think_ it is- and who knows how far it's off?

Also, lots more expensive _may_ not mean lots better gauge.
