325_driver 422 Report post Posted March 27, 2009 Hey guys, On a audi, but its general turbo related Its a new K03 Turbo, And it makes a very slight whistle, Still got heaps of grunt, in fact the most power full its ever been, But i am concerned about the whistle, as i am with any additional noise (And it is NOT a whine) Most certainly a whistle I have heard a few TD03/04 turbos also whiste, and RX7, etc etc It does not whistle much if at all when standing still, revving But under acceleration at speed. There is plenty of coolant going through And nice clean oil going through Any hints ? Quote Share this post Link to post Share on other sites

bravo 35 Report post Posted March 27, 2009 (edited) Interesting - both our large turbo diesel 4x4's whistle very prominently, as does the very very large turbos on the very very large diesel caterpillars (1000hp each x2) on a boat I spend some time on. Thought it was normal. Excuse my ignorance if it's not. Edited March 27, 2009 by bravo Quote Share this post Link to post Share on other sites
