Slumdog Posted March 20, 2017 Share Posted March 20, 2017 Hello everyone I'm new at the forum. Recently bought a fiesta 100 ecoboost. Revving up to 2000rpm while indoors, I can ear a sound/whistle similar to a blow off valve. Is this normal in such a small engine? https://youtu.be/7QoPgaujyTE Thanks Quote Link to comment Share on other sites More sharing options...
Luke4efc Posted March 20, 2017 Share Posted March 20, 2017 Ecoboosts don't have BOV's, but use recirculation valves instead. It's either that or just turbo spool 1 Quote Link to comment Share on other sites More sharing options...

Jonro2009 Posted March 21, 2017 Share Posted March 21, 2017 +1 for turbo spool, either that or there is an owl stuck in the manifold lol. Indoors noises are often heard differently, especially in a multi-storey type environment.Sent from my iPad using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
