Title: Appropriate place to attach a boost gauge
Post by: zmaninco on May 13, 2006, 07:04:19 AM
Hi folks,

I wanted to check boost on our 98 1.8T.  Where in the engine compartment is the appropriate place to attach the hose for a boost gauge?

From research, it sounds like you cannot test boost on the 98 with a VAG-COM, is that true?  If its not true, where in VAG-COM is it tested?

Thanx!

VAG-COM will not read boost on a 98 drive by cable car :x

Best place to have a boost gauge line is between the fuel pressure regulator and the intake manifold.  It is easy to reach and gives good readings

I've got an dual a-pillar guage pod I'll sell you on the cheap I had in my '99

How does a boost gauge correlate to a vacuum/pressure gauge?  I have a vacuum/pressure gauge and am wondering if I can use that to determine boost.  Possible or not?

There are two types of boost gauges, one that shows just boost [pressure], and one that shows both pressure and vacuum.  So yes, your vacuum/pressure gauge is will show you boost.

Ditto, that is where I have mine as well.  Put it in the wrong place and it just won't read, so you will know right off the bat if you have it right.

Maybe I have been watching too much "That 70's Show" but the title reminds me of something Red Foreman would like to answer...

How about a case of 1554 :?: :P :beer: or a six :lol: or $50. I don't care :lol:
Going on the drive on Saturday? I'll bring it.

That is where mine is going to be connected once my boost gauge comes in. My last Omori gauge in the jetta we hooked up there too. Works perfect and is wasy to access for installation.

I have a plain vacuum/pressure gauge.  Can this be used to measure boost?  It seems like there is a direct correlation between vaccum reduction and boost.  Is it a pound for pound correlation (i.e., one less pound of vacuum means one more pound of boost)?
