Leaking air sound under WOT (BOV spring?)
I did a search for BOV spring but the current posts did not confirm a question I have to the tech audience on the forum.
Around 4000 RPM under WOT I start hearing a "whirh / whoosh" and the pressure drops just slightly, not a complete drop. I have gone through all the hose clamps and everything is tight. I know I should replace them, something in the near future. No CAI on my Redline, but I have a K&N tray filter. Does not make the sound under 1/2 or 3/4 throttle. Almost sounds like a belt slipping too...tough for me to distinguish.
At the last WIS-Sol event, MeanSol noticed my BOV was quite "loud" while simply driving around the parking lot. I started paying closer attention to it and noticed with even a short 1/2-second pedal tap, it would create a noticeable BOV "whoosh". His comment and my new drawn attention to it leads me to think it may be too active. Is that possible?
I stumbled on to the spring replacement from Dejon. Dumb question --- woud this be a potential fix? (or do the "spring stretch" as I saw in other posts to increase the load)
Is the pressure under WOT combined with a weak spring pushing open the BOV somehow?
(not being very car-savvy, I want to avoid a new BOV replacement w/o mechanic oversight)
