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

 

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

 

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

 

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.
