oh lord, dont put a vta bov on a Type R either.

lmfao see!!! that's sad... on my poor little ex-t it's justified

its not justified on an ex-t either. Just get an intake, its safer and makes the same noise.

negative on the same noise

um yeah, ive had it both ways, and ok so maybe the bov is slightly louder its also much worse for you car. and if you can safely replicate the sound, why risk it?

it's not the turbo spool i want heard... it's the air it releases that i like. either way this car should give me no problems at all for at least 150k miles. after that I can easily sell it or just buy a brand new cat as thats the only thing I can see that will need replacing...

you do you, thats your choice and your car and Im not one to tell anyone what to do......I can hear the bpv opening and sending air back into the system. So I hear spool and bypass and its very noticeable. Ill grab another vid after work

With that said, just dont be telling people its good for their car or doesnt hurt the car because its a prove fact that it runs rich on shifts and transients. and you can imagine what running rich intentionally for thousands and thousands of shifts can do to your engine. Eventually it will throw the codes. Its happened to a lot of us that ran it.

@Boomba Racing Can I swap for BPV when you release it? I was stalling in my CVT, went back to stock.

I too would opt for a bpv

Unless you're running over stock boost levels, there is no reason to install an aftermarket BPV. Even on the +6psi tune from Hondata, I seriously doubt the factory BPV would leak.

Just did some testing with this bov. Here are the results. On a CVT with a ktuner 21 psi stage 1 tune and short ram intake and 93 octane fuel. Top picture is without and bottom picture is with bov. As shown, it does make it run rich when letting off the throttle, or in MT between shifts. Your car will not throw a code unless the STFT goes below -30. Without the bov it was maxing out at -19 and with it was maxing out at -25. Every time I’d let off the throttle and the bov was releasing air, it would drop to -25. Did not affect gas mileage. Both ended up around 30 mpg for each trip. So it did not affect that. Unless you floor it every single time you drive, as I was doing during this test, this bov will do no harm. Everyone’s been talking without actually having the proof, so here it is. For those who like the sound of a bov, it’s useable but like I said try not to floor it every time you drive

had the same proof that was uploaded a while ago, I'd say that with a M/T after 100,000 shifts where a/f dips for .1 seconds could cause a problem

How much is Boomba Racing paying you?

@Acraig3 i may have found your post after I posted this but yeah the only real issue I’d see possibly happening is the whole carbon build up and even possibly washing the oil off the cylinder walls. BUT many other turbo’d cars from the manufacturer run more rich than these civic x’s Example: STI’s run about a 10 AFR stock during max torque. While with a stage 1 tune on ktune it runs about an 11. So many other cars come stock tuned more rich. Who knows, I’ll be running this for a little while and seeing what happens lol

@SkyeHack I’m just here to learn about stuff I don’t know too much about and when I run across people arguing about something I like to do the testing myself

False info. Everytime you release that air to the atmosphere you are doing harm to your car. Do you know what a BOV is actually for? Why are you running one? There is literally nothing good that can come from running a vta bov on a MAF car.

Please go ahead, explain to me why you think they’re bad

Blowoff valves are used to prevent compressor surge. Compressor surge is a phenomenon that occurs when lifting off the throttle of a turbocharged car (with a non-existent or faulty bypass valve). When the throttle plate on a turbocharged engine closes, high pressure in the intake system has nowhere to go. It is forced to travel back to the turbocharger in the form of a pressure wave. This results in the wheel rapidly decreasing speed and stalling. The driver will notice a fluttering air sound. On a car equipped with a mass airflow sensor located prior to the blowoff valve, venting to atmosphere confuses the engine control unit (ECU) of the car. The ECU is told it has a specific amount of air in the intake system, and injects fuel accordingly. The amount of air released by the blowoff valve is not taken into consideration and the engine runs rich for a period of time. Typically this isn't a major issue, but sometimes it can lead to hesitation or stalling of the engine when the throttle is closed. This situation worsens with higher boost pressures. Eventually this can foul spark plugs and destroy the catalytic converter (when running rich, not all the fuel is properly burned in the cylinder which can allow unburned fuel to combust upon contact with and melt the converter or to cause incompletely combusted fuel to leave heavy carbon deposits).

But fuck it, your car sounds super cool doesn't it?

Don't you find it suspicious that Boomba refuses to acknowledge or talk about why they have disabled the comments to all the videos that have to do with the BOV on the 1.5 Turbo Civic? It's been over a month since I posted in this very thread and they have not answered.

Boomba disabled comments on all their videos discussing their BOV for the 10th Gen Civic.

They have been quiet in this thread for over 4 months (even though they log in daily).

After doing some more digging, I noticed that they allow comments on their BOV YouTube videos for:

- 2017+ Fusion Sport
- 2015+ Volkswagen GTI
- 2015+ Ford Mustang Ecoboost
- 2015+ Subaru WRX
- 2014+ Ford Fiesta ST
- 2013-2016 3.5 & 2015 + 2.7 Ecoboost F150
- MK3 Focus RS
- etc.

However, the only disabled videos (3 to be exact) are all for:

- 2016+ Honda Civic

Do they not stand behind their product? Why the censorship of discussion?

They made a product that the customers want because it makes a whoosh sound and fail to admit that maybe it's not the best thing you should be putting on your car. So they just disable comments and fail to respond to any continuing criticism knowing that they can make a quick buck by taking advantage of people who are unaware.

But at the end of the day its your car. You can do whatever you want to do to it. But you can't argue that its not bad for your car or that its making your car better in any way shape or form.
