    Yes it is possible,you may get it with just a filter change,although make sure your induction kit has a built in return from the standard dump valve.Otherwise your looking at a non-standard re-circulating dump valve(don't get a blow to atmos as it's dangerous with a afm)which may be louder than standard.regards Ryan

    Have a look at AM Tuning for their GFB Hybrid blow-off valve.

    GO FAST BITS Hybrid blow-off valves overcome the problem by venting most of the non-required intake pressure into the atmosphere, while a small portion is vented back to the turbo and airflow meter-enough to stop problems such as excessive fuel use, backfiring and engine shudder at half acceleration (experienced with purely venting-to-atmosphere valves).

    $309.00 Australian dollars + £13.00 postage to UK, which I think works out about £140 approx.

    I haven't tried it and don't know anyone that has either.

    I have a Bailey Atmospheric Dump Valve on a '98 T Sport with 141,000 miles on the clock and have experienced no problems since fitting the new dump valve and it sounds the nuts - get one ordered and fit it - its so addictive you can frighten old ladies :>
     
  6. I also have a bailey atmospheric DV, also no problems, but you may lose a few bhp.

    The age old DV debate! /ubbthreads/images/graemlins/lol.gif

    AmD reckon that by fitting an atmospheric DV you lose approximately 7bhp.

    All depends what you are into... power vs scaring old ladies! I know I ain't no OAP scarer! /ubbthreads/images/graemlins/grin.gif

    Having your car chipped to get more power then fitting an atmospheric DV which loses 7bhp really doesn't make sense to me! /ubbthreads/images/graemlins/confused.gif

    A atmospheric DV will not do anything apart from loose performance and sound silly, cos its just far too loud.

    I (aswell as quite a few other people on here) have a recirculationg DV, and a Carbon Cold Air Intake (CAI). This improves airflow into the engine, and also makes a nice noise... Not loud, but it does make the DV audible, and makes a nice deep growl (again not at all loud) under Wide open throttle. We sell them for £144+vat, but will be a few £ more expensive if you need a crankcase breather. Drop me an email if you are interested!

    Cheers

    Depends how old you are!!?? If your a young whipper snapper with a smart A3 then fair play let everybody know you can afford a turbo - if on the other hand - your an old giffer then every ounce of performance is vital for collecting the pension so get a re-circulating dump valve - i have to say if you have a chipped S3 7bhp isn't exactly a noticeable difference is it??!!

    The 7bhp may not be, but the increased lag will be.
