2019 subaru wrx sti greedy install hope everyone enjoys.

[@anthonyf4525]

If you can clock the BOV, and have it pointing upwards or towards the hood scoop, you'll hear it a lot more.

[@dvandervegt6427]

Good one!

[@RecklessArdor]

Love the music during your install! Great choice!

[@adamthekid7439]

i push 20-24lbs of boost with this BOV + proper tune and it has a beauuuutiful stutututuuuu whistle

[@eflem7708]

I know it's a year later but if you still have it set up like this, get rid of the hard pipe on the Intercooler and put a silicone hose going across with a t fitting on one side and a 90 degree fitting on the other side. And if you want loud go with a turbo xs rfl bov

[@zakwrx701]

I think you have to make it softer, with the nut on top

[@jmmarie22]

Did u buy a plug for your return hose that was connected to bottom of your recirculating valve that was previously installed

[@badoasis3588]

Kobe83647 yes I did on the website when you purchase the item the plug is at the bottom of the page for some reason they don’t sell it together.

[@tmtom6333]

brother what's the name of the plug you put under the valve

[@MrCarmelo345]

I had the same bov on a 2014 Sti but took it off cause I read it was bad without a tune ! Truth or false?

[@MrCarmelo345]

Is this bov recirculating?

[@leoalonso7653]

Look up forge bov thats a good one.

[@blowngasket299]

let me know how this worked out for you, almost bought the same one for my STI. Same year as yours

[@badoasis3588]

I’ve been told I have to get a tune for it after you install parts like that which I will soon if I ever get time but I’ve installed it I think around the 10k mark and I currently have 25k now with no issues but trust I will get a tune soon

[@blowngasket299]

@@badoasis3588 Good to know, thanks

[@rocketboyz1004]

Thank yoi

[@motormayhem4102]

The Hks ones are way louder

[@dustinoman]

Why are you venting it and not recirculating it? Isn't this a bad idea for a MAF system? The computer is accounting for all that air coming into the system and then you turn around and vent it which is going to result in potentially running rich and causing issues.

[@badoasis3588]

Dustin Baxter there’s a lot debate but It’s stated that bov are there to reduce pressure in the intake so venting it back into the intake is a little confusing to me to begin with but As it’s been riding so far with this swap it hasn’t caused problems nor did my other car have any issues with installing a bov but I did notice that my car did pop and crackle a little bit more but I don’t think it’s running richer I just think it doesn’t have the air that it use to have to burn off the excess gas so I think it’s more of a trying to avoid more fumes and noise type of thing with state laws and what not.

[@dustinoman]

@@badoasis3588 glad you haven't had any noticable issues, and I would hope never, especially with a car in this price range haha. I'd 100% recommend a tune for it though even though most of the companies will say it's not needed. My tuner out here in Utah at Simple Performance recommended against it just to be safe since the system is designed the be a closed loop, at least until you start getting into higher power and psi from what bit I've gathered. Getting a tune should help with what you're experiencing now since I'm sure there's something going on. Generally it'll run rich for a second and then drop to being lean because the ECU is trying to compensate for the difference that's happened with the air.

[@dustinoman]

I actually just got the Turbosmart dual valve so I can plan ahead in a way. Plan on running it as recirculating for a while, but I'll see what the tuner thinks once I get my Garrett and need another tune since I'll be looking at 400 at the wheels on just 91.

[@juliansdiamonds]

Great video

[@sexalex]

need front mount to really hear it

[@vytautas950]

What is your BOV name?

[@frostbitemobileautodetaili5944]

Should have went with HKS bov if u need a loud whistle when release to atmosphere

[@badoasis3588]

Techh Tron honestly I was thinking of choosing the HKS BOV but I read that Greddy was a better brand but I had an HKS on my Mazda and it made a beautiful whistle noise.

[@K20TypeR]

I can hear it clearly bro

[@chrisasaurus]

Make it softer

[@sektr3199]

Its not shooting to the atmosphere

[@sergiogutierrez1150]

Mine sounds louder in 4th and 5th

[@Jimmy_Wei]

The correct pronunciation of Greddy should be- G-Ready. Ji- re di

[@wilmarmorales6671]

Do you think is good blow off valve

[@badoasis3588]

After doing some extensive research I’ve come to find that there’s two different types of blow off valves and basically some for when you really pushing power and some to really sounds nice when I owend my HKS in my Mazda it had a beautiful wiffle sound to it if that even makes sense and I really loved it this blow the greddy one just releases all the air at the same time making a big whoosh sound but I think I might change it later on

[@wilmarmorales6671]

@@badoasis3588 which one is the other blow off

[@j20sti]

Lmao trippin you can hear it, it would help if you rotate it upwards so you can hear it more

[@badoasis3588]

Its not as loud as I expected it to be. I’ve owned HKS and they sound really nice but I couldn’t have it upwards because of those black tubes on the intercooler.

[@ryanskinner9937]

i lost 9 pounds of boost when i installed this

[@badoasis3588]

Damn really?? Did you get it tuned?

[@Nerdburger85]

Lol that doesn’t make sense
