I want to get that 'sneezing' sound when I change gears - has this got anything to do with the dump valve?

How much do these things cost and can I fit 'em myself?

Cheers guys!

 

I think only certain dump valves do it, including the Bailey Motorsport Evo, try: http://www.baileymotorsport.co.uk/baileymotorsport/frame.html

 

The dump valves that give the 'sneezing' sound as you put it will be any dump value that vents to atmosphere. Thats the noise you hear. If you buy a re-circulating dump valve that will dump the turbo's air back in to the intake system and you will here nothing. As on a std car.

 

You will hear something on the stock DV if you fit an aftermarket induction kit. K&N 75i for example.

Try and avoid Forge, there not much cop in my experiance.

 

Blitz have a trumpet which can change between a 'whoosh' and a flutter.

 

ah-ha!

i dont suppose you happen to supply these blitz dump valves by any chance jamie?

if so how much would one set me back??

cheers

 

Ahh yes I certainly do Ill email you some prices!

 

Id be interested to Jamie.
Got a Forge at the moment and am not very impressed with it.

I heard a DV that makes the sound is bad for your car. is that ture? and does the car use more fuel with a DV?

 

I think that's yet to be 100% proven either way. I have a Forge v.t.a. dump valve, and I'm very impressed with it. As for fuel ecomony - YES, you'll use more fuel.........but only cos you'll want to take it to full boost to hear the WHOOOSH!

 

Does anyone have a recording of the 2 different sounds possible from the Blitz DV?

Hi i have had a blitz valve on my car and it never made to different sounds it also had a trumpet on it... however my HKS one does... it maks a flutter at low boost and a high pitched whistle at higher boost
