HI EVERY1 DOES ANY1 KNOW OF ANY LINKS 2 LISTEN 2 DIFERENT MAKES AND SOUNDS OF DUMPVALVES ? GOT THE CHANCE 2 BUY A RATTLESNAKE DUMPVALVE ANY1 GOT OR HEARD THIS MODEL ?

 

Please don't! It will make your car sound like a bus and make it run like poo!

 

What are those dumpvalves lorries have coz they're proper loud???

ps; as chrispurvis100 said

 

Don't bother mate, leave it off the car.

 

I would say don't do it.

But I don't know anything so I won't. :

 

THANKS GUYS 4 YOUR REPLIES IS THIS JUST A GENERAL OBJECTION 2 ALL DUMPVALVES ON A SCOOBY OR JUST THAT MODEL ?
DO THEY RUN AND PERFORM BETTER WITHOUT ?

 

Run better without mate, dodgy idle amongst other things

 

Your car already has a re-circulating dump-valve. Nothing wrong with that.
A VTA dump valve, like the one you're on about, will vent the air to the atmosphere, making the ptshh sound.
This ecu will add the amount of fuel for the volume of air it measured with the maf sensor. If some of the air has been lost, the mixture will be rich, possible leading to momentary 'bore-wash'.

You'll also experience pops and bangs from the exhaust on over-run.
Basically, you will be making the car run less efficent.
When I fitted one (big mistake but I will own up to it!), it actually caused more lag in between gear changes and made the car very jerky when applying or coming off the throttle.

 

THANKS GUYS, SO BASICALLY THE ONLY GAIN WITH A DUMPVALVE IS THE WHOOSH SOUND ! HAS ANY1 GOT ANY SOUND LINKS OR ANY VIDS THAT IS POSS 2 HEAR THEM ?

 

THE ONLY GAIN TO A DUMPVALVE IS TO THE SELLERS WALLET
BEST LEFT ON THE SHELF
KIPS

 

PLEASE HIT THE CAPS BUTTON! YOU KEEP SHOUTING!

And I wouldn't call the 'whoosh' a gain.
Plus you'll suffer all the downsides that I mentioned. But, its your money.

 

Sorry did i wake you
