Is your BOV not venting or opening? Out of no where my Forge atmospheric BOV on my Fiat 124 Spider Abarth started to barely vent or open. I finally found the issue and got it working again. If your BOV is not opening or venting properly, this is something to look into!
But I still have another lingering issue where the BOV is very delayed at times. I cover this in the second half of the video. Still trying to figure this one out, so if anyone has any input, drop a comment!

UPDATE: I mention in this video that I may need longer hosing so it would not kink. After recording this video, I looked deeper into the hosing issue and actually it does not need to be longer. The problem was that the hose was in this weird “S” type tangle which put extra tension on it causing that kink. Honestly shorter hose and just moving the hose over and zip tying it so it does not cause an extra bend is the best fix. I’ve come to hear that it’s best to try and keep your hosing as short as possible when it comes to your BOV, so just wanted to clarify since in the video I mentioned few times I may need a longer hose which is not the case.
Looks like you have soft silikon hoses, they will flat out of the vacuum thus delayed venting. You need harder wall hoses. But you have probably fixed this by now.
Great Video! Thanks for helping us by demonstrating the issue and what the culprit was.
You're welcome, and thank you for the support ❤️
Life saver!!! I went stage 2 crackle tune on my Golf r a couple of months ago. Noticed that my BOV wasn’t going off at higher RPMS and inconsistently at lower RPMs. The “crackle” I was supposed to get wasn’t happening neither. I would hear that weird intake flutter as you did. I can’t believe I have been driving like that for all this time lol I found one of my hoses was bent at a 90 degree angle and when I made it straighter, everything is in sync and now I’m getting mad crackles from my exhaust. I just hope I didn’t do any damage to anything 😬😬
The photography legend himself has arrived! Been watching your stuff for a while, love your content 👌 I'm glad this video helped you 😁Before this car I also had a MK7.5 Golf R Stage 2 Unitronic tune, the car was a beast! If you're ever in the NJ area and want to link up for some car content let me know!
Excellent video, really well done. This is Greg from EC, the Forge valve is the best on the market for these cars, but the hose they include is only medium quality. We do stock much better hose, and I'll be happy to send you some, if you want it just give me a call. Perhaps I should put some sort of kit together.
Greg has excellent silicone hoses.
Thank you Greg! I have some extra hosing from when I got your Intercooler and already swapped out the top longest hose. I still have a delay in the BOV (I may just re-hose the entire thing to see if it helps). I spoke a bit with Brandon about it and will try to touch base tomorrow some more. I guess most importantly I just want to make sure it's not causing heavy stress on the turbo if the BOV is delayed like that. And yea you should definitely put a hose kit together! I think people will be interested both for the quality upgrade, and the aesthetics if you offer different colors 👍
dope video all across!
I’m having this same sound with my Mustang Ecoboost. Thanks for the post. I’m going to check that out.
did you ever figure it out?
actually this was obvious in your previous videos. simply turbo pressure in the manifold was backing up to your turbo turbine when you let off the throttle. I didn't leave a comment thinking maybe I was wrong. good to hear you noticed it because it could cause bigger problems.
My 1.6 Ecoboost makes that sound! I’ve been looking for that exact sound because it’s a new thing. That deep whistle sound.
Brooooo thank you I have a forge bov on my mki6 gti and this is the exact sound it’s been making and building low boost. Sometimes works sometimes doesn’t but will give that same flutter growl you were having. Guess ima chase them vacuum hoses
Turn you T connector so it goes straight through with the other line coming off at 90 degrees. Should shorten the line a little as well.
Good idea! After this video (as a quick fix to the kink) I moved the T more over to the left side which basically makes that hard kink area more straight through. I zip tied it over which now keeps that line straight instead of having those weird bends. But I plan to re-hose it and to make the lines smaller and at that point i'll see if re-positioning the T will be better! 👍
See, mine is having the issue of venting while on throttle during a pull. It opens for like half a second, then does it like 2 more times before it continues to climb rpm.I can't find any videos explaining that, so if anyone has any ideas pls help.
I have a 2015 Hyundai sonata 2.0T my bov wont blow off am thinking one my hose are crack or bend like yours cause just got the car and everything was running good till one morning i wouldn't hear my bov go off but id hear my turbo going but it'll lack of power
I just deleted my BOV today, just to get some nice flutter. It will sound better when i get my new intake tube..
Got a turbosmart bov on a audi A3. I used to get that cool “pssh” sound when I let off the throttle. Today, I get a more higher pitched sound. What’s weird is, it sounds normal when the windows are either open or closed, but when I open the sunroof, I get the high pitched sound. Could this be the same issue, or something else?
NB. Before today, it would sound normal whether the sunroof is opened or closed.
My hks bov fluters, but when you release the throttle the boost instantly goes down, so thats normal?, or is that a surge
If the hoses are the same size maybe just turn the t-fitting so that it's straight through and have the t send to the left connector
Thanks I been having same problem genesis coupe fixed it few times but came back di I am now searching the vacuum lines also I think to get plunger inside the big was sticking I took it cleaned it had grooves in it buffed those out and round gasket bad fixed they still got problems
Did you figure out the problem bro because I’m having the same prob with my genesis coupe too
Without BOV opening you hear turbo flutter which is not good for the turbo in the long run.
Usually that line will split to the blow off valve and to fpr.
For what it's worth, no idea if it is related to the V4, but I have a V4 intake and Phase II and I have that same warbling sound (not the boost dump) when I lift.
Hey! Can you clarify what sound in my video you're referring to when you say "warbling sound" vs the "boost dump" sound? Just so I'm on the same page as far as what your referring to, thanks!
@@DrivenDistrict You can hear it the first time in this video at 0:06 just before the boost dump.
@@DropTopTees that sound is caused by the cone air intake, it's normal for a turbo car ! It flutters since is more open, it does it even if you try to accelerate without the panel filter
@@Saca560 Yes. Pasquale mentioned in the video he thought it was being caused by the air filter. Was just trying to say we have the same filter and it does the same thing. Thanks for confirming.
Oh wow thats the exact sound my car is making right now. I was worried my turbo was failing. So can this issue damage the turbo at all? My blow off valve only works sometimes and only at very high boost. Would this mean its failed and needs replacing.
Hey bro did you figure it out because I’m having an identical problem
@@lootgoblin6281 hose was damaged, check hoses for any tears, cracks or even just soft spots that can weaken them. Hope you find what the problem is
Try turning the T piece 90 degrees it should help
that hissing sound part of
Phase 2 tune,
That's the noise I was talking about
On the last video.
I remember you commenting but you didn't get back when I asked what part of the video you heard it so I wasn't sure exactly what sound you were referring to. When you say "hissing" are you referring the BOV going off? If not can you put the time in my video that you're referring to the "hissing" sound? Just want to get on the same page so I know what sound you're referring to, thanks! 👍
So I have a 2013 SHO and I have two electronic BOV and haven’t been able to hear my BOVs at all and my turbos have been whistling louder then usual. Any ideas? I live in WNY it’s been extremely cold but have had 40 degree days and same thing
Have you checked the hoses for kinks? Mine had one that caused the BOV to not work properly. Later on though I still had issues with delay or not venting at times and it was actually the BOV solenoid that went bad. I'm running a Forge BOV and they sent me a new solenoid; after replacing it then it started working again properly. Another thing is it could be sticking...taking it apart and cleaning/grease it could potentially fix it IF that is the issue. I took mine apart cleaned/greased and the issue still persisted so for me it wasn't that.
@@DrivenDistrict I have looked at many of the lines and didn’t notice a kink but at the same time I wasn’t looking for kinks specifically so maybe I missed something. And maybe that’s what is it the solenoids. I have the stock electric BOV that came with the car with the sport package I took one off and used some sensor cleaner but didn’t make a difference. I assume it’s my BOV because before I could hear them blow off and the iconic shwoosh noise from my CAI that I also can no longer hear. Thanks for the advice!
I'm actually having the opposite issue, BOV vents as soon as it gets into boost. Using the blue spring so should be okay
Know this is old but your vac line should be supplying the boost pressure to keep it closed
At 01,23 - this what mine does when am boosting
Mine doesn’t even go off anymore lol
Softer spring…this is what all You need😉
