VRSF intercooler installed. Howling sound WOT on 16lbs..?

forged328 · 09-22-2014, 07:02 PM

Maybe one of the couplers is leaking?

335NJ · 09-22-2014, 07:05 PM

Shouldn't sound much different over stock i'd assume? Might be a leak somewhere, i'd check both connections to start with.

I had slightly more turbo noise after installing my vrsf ic and cp, no leaks or anything

Tiago@VRSF · 09-22-2014, 07:45 PM

I'd recheck the connections at the chargepipe and at the intercooler. If possible do a leak test.

What BOV/CP are you running? Sounds like you may have a leak

Believe it or not it was a oil filter housing gasket! Thanks guys!

Mine whistles much more audibly, and on the sport tune, is holding boost at 14.5lbs steady.

But it's not a howling sound at all.

I'll be adding this to my list of responses to "My car sounds like it has a boost leak"

Seriously though, good job getting it squared away.

You can get a howl from a few places, oil filter can crush and make noises, a connection can leak just the slightest and cause a supercharger sound.

Quick update. It was actually both. Coupler was loose and oil housing gasket broken. Thanks for the input guys!
