Was my old DV fubared?

[cupradan]

Something weird has happened after I've fitted my new 007P. With the old bosch dv installed the turbo would whistle as it spooled up and then flutter when backing off the throttle. Now Ive installed the forge all you hear is the spool up and then the release of boost, no fluttering.

When I had my LCR a few years ago it didn't have the fluttering sound. I noticed this straight away when I picked the cupra up and even mentioned it to my brother but put it down to the different turbo. Does it sound like the old dv was a bit farked and was stalling the turbo? I wasnt losing boost so never thought about it.

If you mean the chatter, its normal with the bosch valve, mine does it and another i know does it. Its a great nose il admit. The forge is a diffrent valve all together hence the diffrence in noise.

I loved the noise it made. Is there any way of getting it with an aftermarket valve? Is it a byproduct of a diaphram valve?

 

[Shaunyboy]

Id say its just the noise made from a diaphram vavle which gives the flutter.

try a 50/50 d/v half recirculating and half blow off noise. it might give you that flutter sound what you want.

how about the APR R1 valve?

i read somewhere that there's a lot of hype about DV valves. some guy said he was running 330bhp and went back to the standard valve from his 007p

Would it handle tht boost well :| the diaphram isnt made for hight boost apps.

if you have not done the n249 mod try that as i get a nice flutter and louder dv noise

if you have not done the n249 mod try that as i get a nice flutter and louder dv noisesince i did mine this afternoon

 

[cupradan]

yeh gonna give this a go nw i know what im doing

 

[JamJay]

Try a 50/50 valve in fully recirc mode, I hear they chatter a bit more

Also to N249 as drue1 meantioned.

Not true. The standard will run fine. The reason the OEM valve gets a hard time is that the rubber over years starts to perish and eventually tears. But when there new there strong enough.
Depends on your set up but BT cars dont always run high boost. Mines only 1.5bar max.

I might stick the Bosch back in and see what it does then.

yeah, that's what they were saying

i think the guy's tuning company (jabba) recommended the standard over the 007p for his car.

On a previous LC my dump valve started making a fluttering noise - SEAT diagnosed it as a knackered DV; put a new one and problem solved. You still hear it spooling up and dumping off but it shouldn't sound like a piece of paper flapping in the wind!

or why not choose function over form?......
