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.

      So I've been working on the car a fair bit, doing a lot of little things.  Still making slight adjustments to my tune, as the cold weather settles in. I've also had to start dropping boost and tire pressure as the weather gets cooler. It's getting very swirly at highway speeds. I drop to 20psi at 20C and 18psi spring pressure at 10C IAT's. I'm currently on 255 Falcon RT660's, but may look into running 275's next summer. They will fit, but barely. Might have to raise the rear a tad.  I'll start redoing my exhaust Monday, as I have the week off. I currently have an oval center muffler and cannon rear muffler. I've been told more then once from people behind me that my rear bumper is going to catch on fire one day. Seems I blow 5-10 second flames after doing a pull. No clue if that's the WMI, as I've never been able to do that before with other cars. I wanted to angle my tip down a tad so flames are pointed down and away from bumper. I also wanted to take the opportunity to reconfigure my exhaust line. I'm going to move my oval muffler to the rear with a pie cut angled tip and put in a new smaller round muffler in the center. I've rocked cannon mufflers on this car for the last few years and want to transition back the oval muffler look. I've also been looking for a stainless project to try out the new solar flux I bought. I'll post pictures on Monday, should be able to wrap that up in a day.  I'm also picking up another rear subframe this week. I wanted a second so that I could modify one with a gk tech anti squat reduction kit during the winter, and still be able to keep the car a roller so I can back it out of the garage if needed. I will also be caging it this winter. More on that later. Lastly, Speedtek still hasn't given me diddly squat. Every week for the last 4 weeks, they have been saying next week. They told me Friday to expect a shipping label that day to ship my two bad sets of ring and pinions back and nothing. There's definitely been more contact since I started destroying their company any chance I get on Facebook, but it's still just words without action.

      Have you done a pressure test on your intake/piping? Cleaned your IACV and Cold start valve?

      KISLOC2 line output convertor for subwoofer in Q50/V37

      By HYBRID VL · Posted

      i was thinking that the 2 wires that go to the sub from factory has some sort of preamp like you mentioned and also a lo Pass filter to get just bass. now that will only use 1 channel and that really should be all i need for a sub? if i was trying to put a set of speakers in the back i can understand cutting into the left and right speaker wires. i will try how im talking about doing it and if that is crap i will do it the way of all wires. thanks for the input guys.

      M35 Stagea intake suction pipe

      By Equilibrise · Posted

      Challenging mig welding thin Aluminium pipe and trying to fit it in, having to bend and twist, but got there in the end. Fits really well and can easily get a socket wrench in there now to put it on/off. I'm in the middle of another project, so haven't installed the suction pipe yet. I'll post some pictures and results when i do.
