Retain the oe recir if your going to use it - other option is to block the oe recirc but you need to mave the larger d/v a true recirc

There is a thread that someone put up for fitting an external larger dv to help combat the chatter issue we get with higher boost running cars. Because the car has a recir dv (put the unused compressed air back into the intake) the ecu knows this and adjusts the fueling to suit. By blocking this off and just having a dv that vents to the outside workld you can have the mixture a bit off between gear changes - prob not a massive issue but still not ideal. I have been running my external (larger than oe one on turbo) for a long time with no problems at all but do vent back in to my hard pipe before turbo. In fact the 1st So if you just want noise you need to run the oe one and whatever ext dv you want and plum into fpr. Hope this helps DG

so the vx has a recir valve and a d/v??? i get what your saying more now lol i thought it was a fact of plug -in-play

No the VX has a recirc valve instead of a dump valve.

No the VX has a recirc valve instead of a dump valve. [/quote] yeh i thought that! so if i wanted to use a d/v, i need to blank off the recirc valve, and make sure i get a twin piston d/v!

Recirc is a d/v and in the case of the vx is attached to the turbo itself. (recirc vents the air back into the inlet system rather than the outside worldlike the d/v you are talking about)

As stated if you blank the oe recirc d/v you want the new ext d/v to be a recirc.

:yeahthat:

plenty of them where i live but when they ear those itb's of mine they better p*ss off

[Nath]

please................. im NO chav!!! i thought the idea of a d/v was to eliminate lag between gear changes! that fake d/v sounds s**T!

The dump valve can help avoid turbo stall on lift-off, but your OE recirc DV already does this job. Hence if you add the to-atmosphere DV to the system, all you'll gain is the fizzy pop noise.
