series 4 stock bov? can u make it hearable? well how can this be done even it can make the smallest of noise just somethings better then none, cheers

 

bump please can this be done need to no asap thanks!

 

Yes, you can. What to do is disconnect the end that vents back to the TID, and plug the hole in the TID. Then put a 1 way check valve on the end of the stock BOV, to prevent it from sucking air in. Now it will be more audible. Do a search on here, some have done it.
Why would you want to though?

 

sorry im finding out for a friend, wats a TID? and a check valve?

 

Turbo Inlet Duct
A check valve allows flow (air or water) in one direction only.

Why is it important to hear the blow-off valve? Smells like a-roni to me.

 

well this he use to have a na silvia sooo and yeh onea my mates mates has a nice old 300zr (imported into australia) sounds mean as **** and well yeh, um his is a imported 7 aswell, so i doubt that will change anything. but thats everyone, much apreciated.

 

Things you'll need.

Bolt, big enough to plug the hole in the TID when the bypass valve is no longer going to it.

Check valve. You don't want vacuum leaks!

Whistle. The referee kind.

Duct tape. Is there anything better? (well, maybe a dremel).

Remove the line going from the bypass valve to the TID. Now install a check valve on the bypass valve so that air only travels out insuring no vacuum leaks. Now attach the whistle via duct tape to the check valve.

VOILA!





















Or use an aftermarket filter...the noise that the bypass valve makes (of air being released) can be heard through the TID.






Or, by an aftermarket BOV, install and plug up the hole left in the TID.

 

Don't use a check valve. This a fairly significant restriction, which defeats the whole purpose of the BOV (relieving the pressure as fast as possible).

To stop the BOV from leaking at idle, you need to alter its vacuum signal so it stays closed at idle but still opens under strong vacuum. Click here for a how-to.

 

Your link is broken. Too many HTTPs.

 

Just jack the idle speed up to above 1,000RPM.
The stock BOV leaks a little if open vented, and bumping the idle up will prevent it from stalling at idle.

Link fixed. Thanks Tony.

 

No one noticed the freaking referee whistle...
