paulgtt Posted March 26, 2006 Share Posted March 26, 2006 car is running standard boost, just under 0.7bar on the gauge.i took the dump valve off the other day and went for a spin and the gauge was going over 1 bar on full throttle!it wasn't doing this all the time just now and again.I've refitted the dump valve and its back to normal.anyone got any ideas on what could have caused this???

Blue Icarian Wings Posted March 26, 2006 Share Posted March 26, 2006 I don't know much about cars, and less about turbo systems, but the dump valve releases excess pressure doesn't it?, so no valve = no release = build up of pressureIf understand what I've read somewhere the pressure release stops air being forced back (the wrong way) through the turbo, preventing stress and damage to the bearingsI could be wrong, ask someone who knows more!

BlackTarw Posted March 27, 2006 Share Posted March 27, 2006 yeah the pressure that should be venting isn't being vented. Quote Link to post Share on other sites
