Lol my exhaust is stoxk. No bov will affect longevity of your engine, period. Unless improperly set up. And the sound quality on the gopro isnt very good sorry. Trust me tho just get a dual port bov if you want something loud and get an intake. The intake is more important than the bov as far as loudness goes also, and really you dont need a bov unless youre pushing more boost. The stock bov is pretty loud still

 

Just for more reference, heres my engine bay. Notice beneath the BOV the injen coupler that connects to the intake. That's the recirc port where air goes back into the intake. If my bov was full vta,there would be a hole in my intake that i would have to plug somehow

 

Yeah, strange somehow its seems louder and clearer with you just cruising instead pulling it must be all other noise overpower it. Thanks for the clearer pic. How's the injen fitment and how big is diameter 3"?

 

I got the intake used, it fits good with the exception of maybe that black cooling plate, took some moving around to get seated properly. Also i was scared the hood wouldnt clear lol. But i like how it looks and that it comes with a matching uicp

 

A vented blowoff valve will cause rich conditions because air that has been measured by your MAF escapes and doesn't get recirculated. Not that it'll cause anything catastrophic, but it'll cause problems. If you're on SD then it doesn't matter for obvious reasons.

Other than that, yes, it doesn't matter.

And, again, an aftermarket BPV is unnecessary unless you're over 26PSI or so and even in that case you can just do the crush mod on a stock one. Not sure if that applies to X's, though.

 

A vented bov wont cause a rich condition if your tuner knows what hes doing. On a non tuned setup in theory it could, but evos run rich from the factory anyway.

 

Correct.
False.

 

I didn't know you could tune bov's, damn, I am missing out

 

Its called an adjustable spring or different springs? Lmao. And evos DO run rich from the factory. Go search it lmao again

 

And go ask your tuner if the BOV affects the tune. He will tell you no, like mine told me.

I have a part vta bov, and my evo doesnt run rich. Idk how u can argue that.

 

wow 5 pages lol

 

Ha!! 5 pages and the consensus still seems to be 50/50.

 

Um actually you can adjust the spring of a bov, in the same way you can with a wastegate. The bov will not affect your tune. My car has a part vta bov and i dnt run rich. Why? My tuner knows what hes doing. Cant argue with results.

Btw i like how the moderator deleted my last post. Guess thats how things go on this forum

 

Unless your tuner has actually tuned your MAP tables and the speed density side of things for that specific scenario of the BOV releasing unmetered air, you will run rich when for the moment your bov is venting that air.

I don't think you understand what people are saying when they say you will run rich, its not all the time or at WOT it's when you are releasing air that the ECU has already accounted for post MAF.

Your tuner is not some god, you are on a stock turbo setup and I am sure he spent all of 1-2 hours on the dyno just like every other stock turbo setup. Meaning you are running rich when you vent air to the atmosphere.

 

Lol a little passive agressive there.. and NO my tuner is a GOD lol. And if your car runs rich for a split second while you vent it will do like nothing to the car honestly.. the evos do run rich.from the factory. If it ran lean, that would be bad. I dont know everything and not trying to say i do, but like i said the bov being part vta really doesnt affect your car in such a way its THAT bad. You have a better chance of running lean and blowing your motor because of bad relays than a vta bov. When people ask "is a vta bov bad for my carr" they usually arent that experienced with these systems, which is understandable. Then people with 6k posts say omg your car will run rich, You make people think you CANT run a vta bov... all I'm saying is a vta bov wont make your car blow up, and wont affect engine life ina significant way.
