Gents,

I have a strange "wwrroomm" noise on my fl only at 2800rpm
Here is a vido.

The noise is there when i reach 2800rpm and bellow or abowe those rpm...the noise is not present.

Can be the turbo, engine mounts, lack of air on that revs?

I need your opunoot on this

Thanks
Zoki

2 things to check:
-Cat resonance,
-Flexi jointer from Turbocharger to exhaust
also
Seal between engine block and manifold.

Hi friend,

Thanks a lot for the fast replay.
Is this a big issue on the engine, can cause bigger provlems or not so big problem?

Thanks

Nope, it will be generate more noise with time, and have less power.
