Magraw69 Posted March 2, 2012 Posted March 2, 2012 Hi guy I'm new here I have an 03 wrx which has has a few engine mods, I have an any forest print out of 340bhp, however my question is, when on full throttle it seems to be continually blowin off boost, it's not doing it when drivin normally, only when foot is flat on the floor, any info on what this could be would be muchos appreciated .
rig-pig Posted March 2, 2012 Posted March 2, 2012 welcome to the fold m8, bo you have a after market dump valve ?? could be that you need a new spring as the boost pressure is pushing it open
johnmacdonald Posted March 2, 2012 Posted March 2, 2012 A couple of years ago, my Forge VTA suddenly started blowing off gently most of the time. Turned out to be a broken spring, which was replaced FOC by Forge - great people to deal with... John
Magraw69 Posted March 3, 2012 Author Posted March 3, 2012 Thanks for the replies guys, it's a baileys dump valve that's on the car, was on when I bought it so no sure how old, anyways I've stripped it off and although everything looks ok, when pressing the piston it moves just a bit too easy, don't know if thats how it should be, i'll borrow my mates and see if that helps, before purchasing a new dump valve. Thanks again.
badbaz Posted March 3, 2012 Posted March 3, 2012 All you probably need is a new spring - use same colour though
rig-pig Posted March 3, 2012 Posted March 3, 2012 if you get a new one, i would recommend forge, i have had a lot of makes over the years and always gone back to forge, last spend was £250 on a turbosmart within a month it was sold and another forge one bought
