Strange noise @ WOT
I've noticed on the few occasions that I got WOT for
more than a second or two, I get this strange hissing/whooshing
noise from the back. It's loud enough to make itself known
over the B&B exhaust!
Imagine a big american car with carbs running without an air cleaner; you know
that 'hiss' they make when they throttle up? Kinda like that, but louder.
I have a vaccum bottle set up to supply the secondary plenum (964 engine)
and I'm thinking maybe I'm exhausting that and causing a leak?
Either that, or when you get a huge amount of airflow, and a large K&N,
you can get a noise like this?
This only happens when I stand on it for a few seconds at a time.
