Boost leak test question

[SlickPyro]

I tried to do a boost leak test and there is absolutely no movement on my boost gauge. I have one of those nxs boost controllers, should I try taking that out and putting a straight thru fitting on there? I had a leak at my j pipe but i put a new gasket in there and still nothing. I think the j pipe might be my problem because I blew out the new gasket to. And I am only running 10-15 lbs of boost. Any help would be appreciated. Thanks.

Is it your stock boost gauge? If not how is your boost gauge hooked up?

Yea i prob shoulda mentioned that I have an autometer boost gauge. it is in a slew of vacuum lines right by the fuel pressure regulator. I'm not sure exactly what line it is tapped into. I can look tomorrow at school. I'm getting ready to pull the motor and put it in another laser shell.

i did the same test to my car and nothing came up on my gauge. i as well have autometer boost gauge.

i have an autometer ultra lite, when i do a boost leak test it shows on my gauge in the car.

Where do you have the vacuum line for the gauge tapped into?

 

[casperfast]

the line off of the FPR. good source of manifold pressure. if u have a large enough boost leak like i had(large hole) than u wont get any oressure. and it can even be hard to locate a large leak.

Do you have switched on ignition, so the boost gauge gets power?

^ That is only necessary if you have an electric boost gauge. If it's a manual gauge, it should work no matter what.

The line that goes to your MBC that provides the boost source should be removed and capped off. This is because your boost controller should have a small bleeder hole in it which will be a boost leak.
