Why do I all of a sudden have a "blow-off" sound?


Recommended Posts

I replaced the clutch and everything feels great. However I noticed I now have a "blow-off" noise when I lift the throttle in 1st and 2nd gear. Only happens when I am driving easy (but enough to build boost) and then when I let off the gas and clutch in I hear the blow off sound. It is not crazy loud but is there for sure. It also seems to be a little delayed. I drove cars before with a blow off valve that vents to atmosphere and this is basically that only not as instant and not as loud. Any thoughts?PS, the car holds a constant 1bar of boost at wide open throttle.
