Opinions On Turbo Flutter?

My friend recently gave me his HKS SSQV III which was brand new, genuine. So I thought why not slap it on, I'm running a stock GTST Series1 turbo and I'm getting turbo flutter in the low RPMs, not so bad at high rpm though, at high RPM I can actually hear the bov not flutter. I'm venting to atmosphere too. The owner I bought it off did a dick move and decided to mechanically tune it to 14psi (I have no boost controller) which pisses me off because right now I don't have the money to buy a boost controller/take it to a mechanic.(is there a way I can drop it myself?)

Is this bad for my turbo? I google around and see too many mixed answers, hopefully I can get someone who experienced the same problems.

Thanks

EDIT: I'm not even sure if it's running 14 psi, I realised the stock turbo would not handle that at all, brb previous owner used shitty marketing tactics.

Put your stock bov back on and it will most likely fix whatever issue you have with flutter.

If its running more than stock boost there will be a boost controller of some description or a new wastegate actuator. Either way it's an easy fix to drop it back to stock.

I'm not fussed with the flutter, Just wondering will my turbo nuke itself over time due to the fluttering and if anyone gets fluttering with the stock turbo and hasn't ever had problems. I heard about mucking around with solanoids to change the boost but my guess now that it can't be running 14, my stock boost gauge isn't showing huge spikes in pressure etc etc and It definately doesn't feel 14psi when I put the foot down haha

And what exactly does 14psi feel like?

It could be running 14psi if the previous owner changed the actuator, as previously mentioned. The stock turbo can make more than 14psi, but it's a time-bomb waiting to go off and it will be way past its max flow anyway, so you won't be getting any gains. That said, if it still has a stock ECU then it would probably hit R&R before it makes 14psi.

Even if you don't have an EBC, I assume you have a bleed valve or turbotech type valve to be able to adjust the boost level? Borrow a gauge and check of your worried...

As for the Atmo BOV... Well they are not a

Popular item around here, so any problems caused by them are generally laughed at...

Put the stock BOV back on, the HKS sound actually gets annoying. My boost is 7psi, the previous owner was talking shit.

Also @ People calling me out, I got a free aftermarket blow off valve why not try it out, This query is directed more at turbo flutter than 'lyk bro how do i get a fully sik flutter wiv out da blow up ov my turbo cuz'? hence the title of the thread.

Because of the problems they can cause.

And now I learnt they are not worth the time and effort/money, also fair enough, I'm new to this forum/cars just getting general opinions, I'll go back to lurking

The guys have been pretty well behaved for a change, generally any mention of a BOV or Flutter goes to sh*t pretty quickly! At least you can now see that the BOV is a waste of time and continue to enjoy the car, with some of the questions you have asked it would be a top idea to get stuck into reading the info sections, DIY stuff and just general info on the forum, you will learn as you go! SAU is the place to be, just read, learn and enjoy :yes:

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA

      That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope!
