I know this is a really controversial topic but being new to owning a turbo car that turbo flutter sounds cool and makes an impression to me and my friends. I've lots of mixed replies when I've asked people how to get a flutter. One friend told me ''Buy an aftermarket BOV and make sure its plumb back!'' But then another friend told me "You can't buy plumb back BOV's and to take it to a workshop and ask them to put a line on it back to the air filters/AFM." Can you guys help me out?! I know some people will say '' Have fun rebuilding your engine in a few years. '' But it's a personal choice and i would really appreciate the help!

It won't wreck the engine. Could potentially wreck the turbo which then might decide to fly through your engine. Being that the exhaust wheel is the weak wheel it's more likely to die but still

It may not happen. But still

Flutter works best with no BOV (flange blanked off) or any BOV with an adjustability that's set to very hard. Atmo BOV'S will screw up the way the car runs too and won't be recommended by anyone on here

The flutter you speak of is compressor surge. That SUTUTUTU sound is because aftermarket bovs have STIFFER springs to prevent boost leak. The stiffer springs can also cause the bov to not open at all, causing the air to rush back throguh the turbo, giving that famous ricey VSHHHSUTUTUTUT.

If you want the flutter, take out your blow off valve, and put it in reverse, so the valve never opens, or just block off the BOV all together. You should now hear some significant fluttering.
If you want a louder flutter, install a POD filter, that shizz amplifies induction and flutter sounds. Want it even more louder? Get a steal intake pipe, then you'll hear it from down the street.

That being said, compressor surge sucks lol. And its a massive cop magnet. Provides no performance benefits, unless your BOV is leaking on high boost. If anything, it provides negative effects such as premature wear on your turbo.

^ why is that each time I put in the word "tttuuurrrkeyyy" it gets replaced with rubbish? lol

Flutters are sick.. if you don't like it - put a stock airbox on.. then when you're bored back off it goes :)

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
