Depends mainly on your current/future boost requirements. If you don't intend to go to massive amounts, then as long as the gauge goes up to 20, 25, or 30 psi, you ain't gonna get it off the scale.

Regarding vac, it's down to personal preference. If the gauge doesn't show vac, it will start at 0, and there will be things going on that you'll never get to see. But are vac readings useful? Pass...

Regards,

Ade.

Edited to say that 30psi is a fairly massive amount!

Hi All!

I am about to purchase a boost gauge but don't know which one to buy,

I have a 96 WRX import and have noticed may different gauge's but I don't know to which pressure to buy as I don't want to buy one that hardly moves or go off the clock.

Any help please!

 

Does the gauge your interested in, read in bar or psi ?
