"Chuffing" (Engine noise content)

Post by Rich H » Mon Mar 27, 2006 10:41 pm

I get a "chuff" from behind my head when I blip the throttle for a down change. Sounds like a poor effort at a dump valve. It's been doing it for a while with no apparent problem but it's annoying me. Definatly sounds induction related but it's the wrong side for the hurricane.

Any thoughts?

Hurricaine resonating through the plenum? Mine always did this with the K&N/plenum combo - never found anything wrong with it.

Interesting... I suppose I'll just live with it, but I'll try and move the hurricane out a bit more, should change the resonances.
