Hi

I have had my 1.8t cupra revo'd for 6 months now, my question is do I need a forge recirculating valve for it or is it just an option if people want the woosh sound on gear change. Im not really fussed about the sound but just want to keep the car as reliable as possible, the car has been running perfectly without one for the past 6 months. so do I need one?

cheers

the forge recirc valve isn't as noisey as others out there but a lot of people have replace the for the OE ones as there stronger, the standard one a just black plastic ones iirc so havea tendency to splt after a while. check back here later about 6:30 after rashcupra and gazjones are in from work, they'll be able to help you more buddy :D

welcome to the forum BTW :wave:

cheers for that, if the standard on breaks will it cause damage to other components or is it just a case of lose of power?

It's normaly just a loss of power, why VW underspeced them I don't know as they must have spent more replacing them than they saved making them that little bit cheaper. Then again as the 1.8's get older they can make the money back through customers paying for the replacements.

The bosh plastic valve is fine for original boost spikes, the N249 valve is there to make sure the bosh valve isn't too stressed.

Now that you've had the ecu map changed you will now be getting a different boost spike. Don't know what the bosh valve can take before it gives up.

If it does break then your car will go into "limp mode". Car feels like a 1.8 NA engine.

The Forge valve is just a stronger uprated valve to to it being made from billet aluminium.

The FMCL007P valve dumps the charge-air back into the air intake system keeping external noise to a minimum. (If you have an aftermaket air-filtter, then it sounds a bit whhoooooossssshhhhhyyyyy.) This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

as already pointed out the standard oem boosh recirculating valve is a weak link when the car is mapped and boosting more! the n249 valve is to protect the oem r.valve from breaking but when remapped it is prone to fail ive got a forge recirculating vave and have bypassed the n249 valve as it is useless with the uprated forge part but witha grenn pannel filter and a moded airbox the forge gives a nice suttle woosh noise

throttle respose was improved slightly
