I actually had a chance to try it out before ya made the vid, i can definitely vouch for ya, this shit makes the blow off valve work sooooooooooooooo much better, throttle response feels way more responsive, also, for anybody wanting to try this, reset your ecu by disconnecting the negative battery terminal for 15 mins, drive regularly for about 15-20km, and that'll give the car a nice little refresh and it will learn your new driving data. My car runs very, very smooth now.
Yeah I made this video a few months ago and after driving with it for a while it’s sooo much better. No more annoying blow off valve noise every time I let off the throttle and I get more turbo flutter. It also felt a little faster but not sure if it actually is or not
@@IvanJrFOST I believe turbo flutter is back pressure going back to the turbine, don't think it would hurt it depending how much back pressure but longivity of the turbo might put stress on the bearings
Nice video. I've ran the vacuum off the manifold with a TurboSmart 50/50 for about a year now. A little bit of flutter when under vacuum or light driving instead of it going off all the time. Well worth it if you have an aftermarket BOV. It may be necessary to adjust the BOV's spring preload a little to make sure it is still shut at idle and goes off how you like it.
@@BLK_GOD just cause the process is being co trolled by the ecu. You'll get the blow off constantly if you don't by pass it and run directly from the symposer which is a true vaccume source.
I just did the vacuum hose while i was cleaning the intake valves, before replacing the intake manifold with the Mountune one. It has a "bunghole" with a little hex plug to tap into with a barb. I added some polyester wrap to the hose so it looks like the other hoses in the engine bay, i like the OEM+ look now i am waiting for the ecu to reset by disconnecting the battery.
Just a thought, but wouldn't you want the hoses to be resistant to oil blowby? Silicone, while fine with coolant, isn't the best for oil. Ofc you could get around this by having a catch can, but otherwise keep in mind that there will be some oil contact with the vaccum hose.
So you prefer thd compressor surge sound over the bov whoosh sound? Bc you're getting a sound no matter which way you do it. Compressor surge is unhealthy for your turbo while the bov whoosh is healthy for the turbo. But to each it their own.
Wrong , compressor surge under load is bad for your turbo, Since the flutter here is under no boost it’s poses no real risk to the turbine. If you fluttered after a full boost pull it would be bad, but this is under vacuum
I just did this to Mine. I do see that it holds boost better like you explained at the end. I barely hear the bov unless Im in full boost. When im in the 1 digits i hear The slightest bit maybe i gotta adjust the bov? Running the turbosmart 50/50
If anyone can help me id appreciate it, I have turbo smart, I installed everything like the tutorial stated but sitting in idle my rpm’s move 200-500 rpms and when I’m in idle and rev it , it sits at 4k rpm’s and doesn’t go down for like a minute.
Just so you know I ordered the vacuum line with the link you put and it’s wayyyy to small. So maybe an old link. It was only a $1.00 so no big deal. I was like 5mm does not seem right lol so my bad on my part too 😂
So I did this mod and it sounds really good, I’m just concerned of the reliability of it. I drive around 70 miles everyday just about for work. Don’t know if I should keep it or take it off and put it back to normal.
Calib Linex I’ve had it for several thousand miles and haven’t had any issues. I don’t think there are any negative effects if you don’t purposely make the flutter noise all the time
Nickjoenap cool, I’ll probably keep it for a while as long as I don’t see issues. And it’s tempting to make it flutter all the time lmao sounds so good
This might be me just talking out of my behind, but I think that if flutter is happening without real positive pressure, it can't be that damaging or anything. I reckon if you had flutter on boost, that is a ton more force on that turbo, but that's not what we're seeing or hearing in this video.. These cars factory have slight flutter already, albeit on barely touching the gas, but it's there. And lets say we do kill the turbo, then we just upgrade it for a big one! Perfectly justifiable! ; )
I did this ab a week ago I have a turbo smart bov and now I can hardly hear my bov hard to tell in the video but under no or really light boost does your bov make more of a pft noise just wondering on how I could meet right in the middle to get it to vent to the point of me being able to hear it you think I just need to loosen up my bov a bit
Aye dude. What's the exact model of your DV+? I've had mine for a month or so and played around with adjustments but I'm not noticing a difference from the factory bov.. Any chance you can help me out incase I'm doing something wrong? Or maybe just bought the wrong one lol
What intake do you have, your turbo is so loud, from the video it just looks like k&n filter but i have a green filter and my turbo isnt that loud, im gonna get everything to do the true vac source later this week! great video!
I’m running a Cobb filter, (green filter should be fine) a custom air box, and a bigger metal intake pipe with an after market elbow. I don’t know what brand the pipe is because I bought it used but any aftermarket pipe will help make the turbo louder. Here’s 3 videos that will help make your turbo louder ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3BB_Blz4Y5k.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bzg2b6V0Z9E.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q4_FDWLKCls.html
The flutter would be bad for the turbo if the car had a really tight bov or didn’t have one at all. The flutter only happens under little load and is t really a big deal. Obviously it’s not great for the turbo but it’s not going to cause damage if you don’t abuse it. The real benefit is the bov doesn’t vent when it doesn’t need to and it will supposedly hold a little more boost this way. The stock one is electronically controlled so it releases way to often
@@Nickjoenap I see. So, low load flutter is fine. Just as long as the BOV is venting when it should. I'm just worried about breaking my stock turbo. I'm not ready to go Big Turbo just yet. Lmfao
I've had the turbosmart 50/50 on my car for a few months and I'm looking for other options. It's way to loud even with stiffening the spring, and it blows of constantly. Super annoying. Cool video, I might try this just for fun before I remove the 50/50. Gives me a reason to finally get around to installing my symposer delete.
I’m just seeing this video and I saw my car already came with that mod lol. can I run the car without the hose ? i kinda wanna take it off but idk if it’s okay to just take the hose off and leave it as it is
Don’t know if you did it or not yet but I wouldn’t. Unless you have all of the previous parts of the sound symposer. You could also just take off the house re route the BOV cable to where it was and put a small plug where the hose connects to instead of it having its little nub
Andrew Eastman no because it doesn’t flutter when there’s actually boost pushing through it. It only does it at low rpm but if you do it non stop I’m sure it’s not good for it. I’ve never heard of true vacuum causing any problems
@@Nickjoenap can we get another update I’m really planning on getting it but I heard it’s not the greatest for your turbo but I also really want that flutter
I really like this mod but I do need to know one thing where is that boost pressure going when u let off the throttle and the blow off valve doesn’t go off
It goes through the turbo which makes the flutter sound on the wheel of the turbo. Normally it would be bad for the turbo if it was under high boost pressure but since it’s routed to true vacuum it only does it when it’s under low boost and rpm. It only does this when you are trying to though. With normal driving the bov doesn’t open fully but still lets out the pressure so it’s a lot quieter since you aren’t building as much boost
@@Nickjoenap okay cool, I just haven’t gotten much flutter from my GFB DV+, did you tighten the set screw all the way then loosen it? How much turns did you loosen yours? I’m also on stock intake right now and full straight pipe so my exhaust is extremely loud. I’m probably going to remove the sound dampening material from my hood as well to get so more noise. Thanks!
ahac technically it’s not good for the turbo but since it’s only set up to happen under little to no load, it doesn’t really have an effect. If there was lots of boost hitting the turbo fan it would be bad but the bov keeps it from doing that
i just did this, but it still vents allot. I'll be in any gear, barely press the throttle and on release it vents. it in no way flutters like yours while driving
Sounds great but could possibly shorten the life of the turbo. We all love the flutter sound but the truth is is that the spooly snails hate it. Is it still holding up okay Nickjoenap?
Hey, not sure if you're still active but I did this to my ST and am hardly getting any turbo flutter. There's maybe a tiny tiny bit of flutter but I absolutely cannot hear it over the sound of my engine / exhaust. I still have a stock intake + K&N air filter, but assuming I did everything right, it should still be somewhat close to the volume you showed in this vid. I'm wondering if maybe the BOV is loose? Basically ~2500 rpm or less (no boost) i hear a quieter "pshhh" and sometimes a little flutter, and above 3k rpm / more boost it's just the regular "pshhh".
Intake makes a huge difference, my ST didn’t flutter before but now it flutters slightly with the Cobb intake and BOV I’m about to do this vacuum mod can’t wait to hear it
I’m not one to hate on you brotha I do appreciate the video because it was a help but your size on vacuum hose is not right the 1/16th is very very small like not usable small just putting out there man! Love the video thanks!
The vacuum line from my symposer delete is connected to my BOV. Is there anyway to reroute the lines to do this? Hearing the BOV line go off all the time is annoying.
What bov do you have? If you have one that’s routed that way it shouldn’t need this. This bypasses the electronically controlled way of controlling the bov which sounds like you’ve already done
@@Nickjoenap yeah but the bov goes off constantly regardless of how much boost. Also this is the sound I am trying to get so I guess my only option would be to get rid of the bov.
Hey man, you probably don't know the answer to my question, but I wanted to ask anyways or if someone who might of had the same issue can help out, but I did exactly what you did to make the true vacuum source and my bov will not vent. Like even on WOT, full boost, it would not vent. I put it back exactly how it was originally and the bov vents perfectly. Any idea why that could be happening?
Have you happened to have any turbo lag when changing gears aggressively? I'm trying to figure out if it is my GFB DV+ while on true vac source. I'm playing around with loosening it currently. It's very inconsistent but it'll bog down for a good second between gears randomly. I have heard the DV+ is intended to use with the original bypass solenoid is all.
@@Nickjoenap yeah just saw that video actually. Thanks for the quick response, I feel like it's not responding properly to true vac. Think my mech got rid of the factory one 😔
I just did this mod and routed it exactly like you showed in the video. I’m not getting the same flutter that you are. I have a stock intake with a green air filter and a turbo smart blow off valve. Did I do something wrong or is it just because my intake is stock? All I hear is more burbles from my exhaust.
@@Nickjoenap thank you for you’re response! Does your elbow make that much of a noise difference? It looks like you’re intake is stock besides the elbow?
@@hunterstahlheber It seemed to make a little bit of a difference. The intake pipe makes a big difference too. I also removed the black sound deadening from under the hood and that helped hear more turbo noise
Hey. I just did this today and is it supposed to sound so quiet? I also get no flutter at low rpms. I felt like i did something wrong since my hoses were set up differently than shown in the video
Joseph Medina There’s a chance something could be wrong, just make sure the hoses attach at the same points and you cap it where I did. It’ll still make a pshhh noise when under a decent amount of boost, it’s just a little softer and quieter. The flutter only happens when letting off after building boost in low rpm. Check your boost gauge to make sure you’re building boost and it’s releasing the pressure after letting off
dtfreshh the flutter doesn’t happen a lot. If you rev it with the hood open or build boost and let off the throttle under 2500 rpm in 3rd or higher it flutters. You’ll need at least an aftermarket intake filter with the cover removed to hear it. A full intake will help and removing the sound deadening under the hood helps the flutter be louder too
@@IvanJrFOST Both, this should be better for hard driving from what I understand. The bov and wastegate now work off of the real measurement of boost, not the electronic signal that the pedal was lifted so it should be more accurate. I do a full throttle pull at least every few days and everything works great. It’ll sound and perform different based on how much boost it was pushing before you let off so it doesn’t flutter from normal driving or pulls
Technically it puts extra stress on the turbo but the way that it’s set up keeps it from fluttering under high load so the cons are next to none. Some people don’t even run bovs on high horsepower cars and they’re fine so this shouldn’t cause any problems
I have a 2015 Ford Fusion 2.0t and I have the boomba sound supposer delete and BOV. What size did port you need for the port on the sound Symposer delete kit? (My Boomba kit has a tap already and I would just have to screw in the port) it should work right?
also did you use teflon tape when u put the boost port on the symposer plate? mine wont go in by hand i gotta use a wrench just wanna make sure thats normal? its a steeda kit
ahac not sure if the vacuum line would fit or not I’d ask steeda. You probably don’t need Teflon tape since it’s that tight they probably made it to where it sealed when it’s screwed in
@@Nickjoenap tried it and everything seems to be okay, where is your spring loaded at? all the way closed or open? and when your bov goes off at around 3k-3.5k revs is the pshh really quiet compared to beforee?
@@Nickjoenap thanks for the reply man. I have a full intake and mines flutters already but I want it louder lol I don't like bov sound 😅 I prefer flutter sound.
@@Nickjoenap I'm just going through that right now with my recent HKS install. It flutters on low RPMs. Same setup as yours. I just don't want to cause any issues with the turbo.
That problem should not exist if the Ford engineers where given a free hand and support, I’m a license electronic technician and automotive general mechanic for 50 years.
