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.

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...

      It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
