Boost gauge Q's
 

I am thinking about buying a different boost gauge & i am considering the vdo package from 42draftdesign.

However, i dont like the gauge that goes -30hg / 25psi, I prefer the 0-30 psi gauge. If boost does spike above 25psi, i dont want the gauge to get damaged either.

I would appreciate any insight on why i should get a gauge that shows me vacuum, as i am not too concerned about vacuum? Maybe i am missing something???

all insight would be appreciated.

Thanks :beer: {thumbup}

well the car idles at about 20 in-hg vacuum, and mild driving goes from vacuum to boost, so it is something you should have....

Hummm. I understand, but not sure if that alone sells me on getting 1.

Thanks for your input {thumbup}

Why wouldnt you get one that shows both? You can get an autometer that shows both for like 60 bucks!

because if you have a BOOST LEAK, it'll show up. . .that's why. . .

? Can you explain please.

Please dont take this as me arguing, i am just not following your thinking

Here is why i disagree & my thinking regarding your response:

if your measuring your boost/vacuum reading in the factory location; within the plenum, your gauge reading is observed between the throttle blade & inlet valve. if you take off all the i/c piping & idle the car, you would still get the same vacuum reading.

if your talking about boosting situations @ wide open throttle, you would see less boost with either style gauge, feel the car being slow & hear a louder than normal whooshing sound.

Help me see your points

Thanks again for the input {thumbup}

I like the vdo look, but dont care for the cramped numbers of the vdo gauge that has both.

I am hoping there is a signifcant reason to get the gauge that has both over my visual dislike of it.
