Boost Guage Problems

[brendo_87]

hey people im havin a couple of issues installing a blow off valve to my r32.

I have tried 'T' Piecing the boost guage vacuum line into 3 different vacuum lines off the intake manifold including the line for the stock boost guage. In all 3 situations the guage is reading off the clock vacuum presssure about 40psi in vacuum then on full boost it only reaches 2psi :S

just wondering if anyone has any suggestions.

oh yea the stock boost guage seems 2 be working fine.

Thanks people

tee your boost guage off the fuel reg vaccum line and use the line from the plumb back bov to feed the bov

I'm a little confused, I assume its a new boost gauge you are installing and not a blow-off valve? If you were installing a BOV I would suggest using the factory BOV vacuum line. If you are installing a boost gauge you can either disconnect the factory boost gauge vacuum/boost feed or tee into it. If you tee into this line you should get the same reading from both gauges. If you don't then one of them is faulty.

The factory vacuum/boost feed is from the back of the intake manifold on both RB20s and Rb25s.

Hope this helps.

Cheers

Is the gauge sitting at zero with no signal? Sounds like it's well out to me.
