just fitted a blitz inducton to a uk MY98, Dump valve is the standard fitted subaru one. should there be a whistling noise as i accelerate, is this the dump valve or the turbo??
i get the woosh noise as i drop the revs, but i was expecting that.

if this whistling noise is not suppposed to happen how can i rectify it?

cheers
chris

 

yes whistle is normal/mixture of air sucking in and later the turbo spinning up

 

cheers ninja,
i thought as much, just wanted confirmation
