Be obnoxious and break necks like VenomousSVT and I and get the Boomba Racing BOV. Loudest option available. Great company too.

Turbosmart dual BOV is pretty nice. You can make it quiet or you can set it to be loud.

If you're referring to the Mountune recirculation valve, no you will not hear that. I have it, and I certainly don't hear it. But then again I didn't want to hear it anyway. If I wanted to hear it I would have bought a BOV.

silly question...the boomba you have @VenomousSVT did you have to do a tune on that or is it safe to upgrade without worry
You don't have to tune for any blow off valves. It's a direct replacement.

When I purchased my car from the dealership used it had the Boomba already installed and was stock tune and only had an intake. It's by far my favorite BOV option because it's loud and sounds heavenly. Plus, it turns head and distinguishes my car as "not just a Focus."


Edit: I will add, however, that the stock electronic boost control solenoid is awful and it will cause issues with any of the options available where you are going like 80mph with the accelerator in the same position or cruise control on and it'll go "Psst.....psst.....psst...." if you hold at a certain psi of boost like -1.0psi. It's the cars way of making sure you aren't holding your engine at a load if you don't need to...but if you sit on the threshold at 80mph it's very annoying. It'll also go off often when accelerating when it doesn't need to. The way to fix it is simple. You either get a tune and request your tuner to adjust it, or you run a vacuum line from your symposer delete (if you have one) to the bov for a true physical boost source. If you go the second route it's like a 2 dollar fix and really simple. If you do that, it'll ONLY go off when it needs to.

you dont have to change anything to run a BOV on our cars. They run perfectly fine on a stock car.

i wont argue with this "edit" however I will add, it seems it only effects some people. Mine on a stock tune didnt react any differently than after I tuned. I only ran to an external source for testing purposes. I'm back on the solenoid now though.

Thanks, I just was not sure since going from a divert-er valve to a atmo valve i though might be a little different on the turbo system.

on cars with a mass air flow sensor IF the air has been sampled it will need to remain in the back side of the intake path and cant be released from the intake. With map cars you dont run into this as its reading pressure via the intake and adjusting.

I ran a BOV on my procharged cobra, sounded like a big turbo car. However I had to run a blow through MAF.. so my MAF was tuned AFTER the blower and my BOV was between my intercooler and MAF.
