silent blow off valve?? possible?
Any ideas on making my blow off valve silent, or close to it. I think it'd be fun to keep people guessing. Ive got my intercooler hidden, and my exhaust outlet is only 2 inch... It looks sleeper, but still sounds like turbo..
Setup:
Honda Civic hatch
DSM t25 turbo
1g dsm Blow off Valve
9lbs boost.
I was thinking running rubber hose from BOV into either a padded box ( cotton, poly-fill, etc) or running the hose thru the firewall, and into the car.
What do you guys think.

From what ive read:
Q: I have heard of a BOSCH or other bypass valves being vented to air, is this possible?
A: Yes, but not right away. If you vent the bypass valve to air, your car will stumble and
most likely turn off between shifts. The reason for this is that once all the pressure is
released the bypass valve will still be open and create a huge air leak which the AFM
does not like. If you put a one way check valve on the end of the output, this will only
allow the air to go out, but not in. Be sure to seal the other side of the intake where the
air would normally be vented. This makes for some interesting sound effects!

It does, if it is too close to the filter.
