So being the newbie i was i had originally bought the Boomba BOV. That sounded AWESOME, but its not good for the Computer/Car to lose all that air. So i got smart and got the Recirc valve, it makes no noise that i can hear but its rated for up to 75 psi which is nice when i decide to drop in a new turbo. IIRC the stock valve is limited to 25 psi? Tbh i like the aesthetics, cause all the wooshing noises come from my intake anyways. Its definitely a quality product.

Yeah that’s what I was wondering is if their BPV actually made a difference in sound over OEM. I saw they made a BPV and never actually saw anyone running it so I never knew anything about it. Thanks for your help!

stock valve is in no way shape or form limited to 25psi. your boomba recirc valve is a total waste of money as the OEM one is more than sufficient to handle anything you're gonna throw at it.

if anything i'd say the OEM is safer as the spring pressure is known by the ECU whereas the Boomba is questionable at best. if that Boomba doesn't have the proper spring pressure and the ECU calls for the valve to open and it doesn't open enough your engine could be in for a world of hurt.

Our BPV is definitely going to be able to hold stock or higher PSI numbers with no issues at all. We have many customers that have it installed on their vehicles for thousands of miles.

Thank you for adding your voice to my thread! I love my BPV, and the stock one was boring. Appreciate the quality product.

Ha...busted!

Yes. I daily this car with the turndown. It took some getting used to and the drone gets bad. NGL I just wanted to get rid of the "HDMI" and I had just dropped money on the Rv6 dp/fp so my budget was limited. I've got a full catback system in the mail as I type this so it was merely a temporary toy. The L15B7 has a beautiful sound that I truly didn't expect.

Added some more sound clips. I know its trash quality but you can get a feel for what the turndown sounded like.

Quick shot last night after the storm, removed the red from side mirror, and trunk stickers. Going to be chrome deleting soon, with old skool Honda emblems replacing the stock ones. Depending on heatsoak over the summer, next BoltOn most likely IC w/cps.
