nice turbo sound

[quattro-nick]

i wonder,how can you get a sound like this movie link,i realy like it

http://www.youtube.com/watch?v=f-AMZ6C6K3o

can i accomplish this with a gt3076r?
is it only with high boostpressure or is it depending off your wastegate or
divertervalve (dumpvalve)?
maybe it's no good for the turbo??

[popdemonic]

the sound is blow off valve since the sound will only come out when let off the gas.

[Rusty]

The amount of movement in toe of the front wheels is interesting!

3" straight through exhaust, atmospheric dump valve if you move the MAF to the pressure side, open filter and loads of BOOST.

[quattro-nick]

can it be that the enigne has no dumpvalve at all and that the turbo slow down with fluctuations
i use vems so no maf for me

[Rusty]

No, that's not a good idea and gives a different noise. This is just a big DV going to atmosphere and a lot of boost.

[quattro-nick]

what's for you a big dv? example or picture?

[Rusty]

Dahlback do larger bore (for example) or some use 2x normal 25mm DVs to get enough airflow.

Is that torque steer?
I was wondering recently about the possibility of that rearing its head due to the front shafts being slightly unequal lengths....

[Rusty]

No, I'd suggest that it's either bump steer or the wishbone bushes moving. OE rubber ones are terrible for this.

[Error404]

I wasn't so sure it was bump steer, I couldn't really see the front ride height change dramatically as it was strapped down, it'd need some serious angle on the track rods to bump steer like that! Wishbone bushes is a very good point, shame we can't see the other wheel to get the full picture. It's quite worrying to see so much toe change

[Rusty]

Back does it as well...

[quattro-nick]

is there anyone here on the forum that this turbo sound has on his car?
what for setup do you use than?(turbo-dumpvalve-max boostpressure)

You disconnect your vac from recirc valve yes your right not good for turbo as it knackers the turbocharger faster.... The sound is air hitting the turbo blades making this distinctive sound not your wastegate or recirc valves or bovs
