Recirc valve blanking plate on T5 ME7?

**simpT5** · Thursday 11th February 2010, 23:35

Can I safely put a blanking plate in place of the factory recirc valve and not have any external dump valve?

I know this causes the turbo to stall and produces the 'chatter' sound, which I prefer over a dump valve.

Can I do this on my ME7 T5 without upsetting the ecu?

Whilst I'm aware that causeing the turbo to stall everytime I lift off the throttle might shorten it's life a little, Ive also read people saying T5's don't run high enough boost levels to cause concern?

Any advice will be greatly appreciated
cheers

No you can't. ECU will throw a ducky fit.

Ive got a blanking plate and no dump valve on mine and my mrs hates it. Says the racket is embarassing!

Is it loud then?

At the monent i'm running a K&N 57i filter and I can really hear the factory recirc valve. Blanking it off was just an idea?

The more I read about my ME7 management setup, the less inclined I am to fiddle!

Very loud. If you get the revs up then lift off its like a gun going off. Mines pre-ME7 though (i think)

Pre-ME7 will tolerate this as they have less sensors and are a little more stupid, bit like me. I have a cone filter from IPD's on the 19T and you can still hear the recirc valve - no issues. Mine is ME7.

I assume the one way valve would fit inbetween the vacuum pipe to the recirc valve?

Am I right in thinking the recirc valve requires vacuum to help it stay shut under boost, hence why you can't just remove the pipe to it?

Any ideas where I would get hold of a one way valve?
