Boostjunky Posted May 22, 2016 Share Posted May 22, 2016 Does anyone know off the dump valve on the ecoboost engine can be closed off to create the flutter sound? Quote Link to comment Share on other sites More sharing options...
alexp999 Posted May 22, 2016 Share Posted May 22, 2016 The ecoboost doesn't have a dump valve. It is a recirculation valve, so the bit of noise you hear is pressure being released back in to the intake, before the turbo. If you want more noise out of it, you are better off getting an induction kit. Mountune do one which won't affect your warranty. Just avoid the kits which are open under the bonnet, the ecoboost engines run hot and the turbo is at the front right near the air box on the 1.0. 2 Quote Link to comment Share on other sites More sharing options...
Boostjunky Posted May 22, 2016 Author Share Posted May 22, 2016 Ok thanks. What if you close off the recirculating valve? Quote Link to comment Share on other sites More sharing options...
alexp999 Posted May 22, 2016 Share Posted May 22, 2016 You'd get no sound at all and over speed the turbo. It has to have some sort of pressure release. You might be able to get aftermarket ones which dump some to atmosphere and some to intake, which would create more noise but I don't know how they'd affect the engine. It's going to sound a bit halfords/McDs car park if it's too loud anyway, lol. Better to try and enhance the whole induction noise IMO. It makes a lovely growl the 3 pot, sounds better than my ST, haha. 2 Quote Link to comment Share on other sites More sharing options...
