Induction noise

[Chefy83]

Hi!

Ive noticed when my legnum goes abouve 5psi there is change in the induction note much more of a whooosh similar to having a pod filter.

Im guessing this is not normal and may be a boost leak? Or even a turbo actuator problem?

Sounds like a boost leak.
Check all your clamps are tight.
I once had this on another turbo car and traced it to a crack in my intercooler.

What boost are you running?
My boost leaks tend to present as a whistle rather than a 'whoosh', but I run much more than stock.
Maybe BOV? Do you still have the plastic factory one?

Some dodgy ebay one that vents 50/50. Will get a gfb Recirc one soon
