To your dignity.... yes....

There are SO many topics on SAU about BOV's and not running them, blanking them etc............

My understanding is that you could bend your turbo blades. By Blocking off the BOV the built up pressure that normally gets released to atmosphere or recirculated, has nowhere to go but back though your turbo and as such temporarily stalls the compressor, which can bend or brake the blades, and the stalling of the compressor is what gives the flutter sound.

Lawl! These threads always deliver!

But the whole flutter thing will soon be annoying for a daily drive!

AND you can get EPA's based on it anyway as its still creating a sound!!

In other words, DONT DO IT!

You f*#@Kin idiots..... The 'flutter' sound is called compressor surge. it is NO GOOD for your compressor blades, it slows down your turbo from spooling in between gears and in worst cases, f*#ks up your compressor blades.

Sometimes when people get too ambitious with sizing their aftermarket turbo and get the housing sizes wrong, or over fueling at idle because they didn't reconfigure their fuel map properly after they fit a bigger turbo, compressor surge OR 'flutter' is the result.

The whole purpose of having a BOV is to release the excess boost so it doesnt slow down your turbo in between gears.....its for response.....WTF would you sacrifice response for a sound ?????? fu*kin idiots

Man, I really wish these kids learn about the fundamentals of engine mechanics before they make a total dick of themselves or worse, totally ruin their cars.

      The spray cans were in the "Kiln" room whilst I was preping the parts,  so probably around 2 hours to get them warmed up, the kiln room has 3 small ovens running at 100°c, 3 medium sized ovens running 100°c, and the large one I used running at 80°c, the room itself was about 28°c, I also spent a bit of time taping up the parts in the room as well, and by the time I was done I would assume that the parts were around that 28°c As for power, I expect a couple of Killerwasps up high would be achievable with the current mods, I'm still running the MZR 2.0 intake and throttle body, and there is a slight mismatch with the 2.0 intake (smaller) and 2.5 intake ports (larger) on the head, this intake is matched and specifically designed to fix this issue with the ports mismatch, the throttle body is also a couple of mm larger, OEM is 65mm, the Bosch is 68mm In the end it will look "prettier" than the molded plastic thing that is the OEM MZR 2.0 intake As for the LSD, it's the OEM Torsen which works fine for what I use the car for, plus, basically no maintenance apart from the occasional oil change

      Mate , I have the same issue right now with the exhaust noise , if you can tell me what your local guy did , I'll talk to my guys and see if they can do the same. Power is good but it just too loud when put it down.

      The other trick I've found with wrinkle black is to put the can in hot water for a bit to warm the paint up, and to pre-heat whatever you're painting. It'll be interesting to see if you pick up any power with the intake, following with interest. Got a proper lsd for this?
