c20let boost problems

[Shaun]

hi guys..

quick question about my let nova...

the boost gauge is in minus? if that makes sense?

what would cause this?

[Shaun]

the gauge is showing -0.6 bar

[Rich]

under boost or on idle?

[Shaun]

both mate

when i drive the boost goes up but still doesnt go into positive pressure

[krobinson]

It should be in Vacumm when not under Load, but should show some pressure when under load.

Does the car feel like its boosting? if so, it could be a faulty gauge.

[Shaun]

cheers mate, will try and get hold of another boost gauge to try

[Benn]

When driving (just cruising) mine sits at -8psi ish most the time. That's normal.
Its only with you nail it (putting load on it) the turbo spools up and makes boost.

cheers mate

But yeah if you are putting the engine under load and seeing no +pressure then youve got a problem somewhere.
