Diverter Valve question..

I have a 12 plate FR+ I got it in 2014 with about 9-10k miles on it so I think it most likely has the factory one, but I have no idea what the factory one at the time is.
Car just feels a bit sluggish to me so I was thinking about upgrading it to see if it makes a difference.
I have heard a turbo whistle when holding full throttle. There are a few different revisions though aren't there, not sure which would be the best to change it for.
Also seen the GFB one which is about £100 or £140 for the noisy one.
From looking on Google, rev D is listed as being the later design not rev G
Rev g has the rubber diaphragm, where as the d has a plastic diaphragm
If you get an aftermarket air intake you will notice a high pitched flute sound when going WOT, it eliminates that which was good for me.
Is generally stronger than the oem DV and can hold boost better, also holds on to boost better when shifting meaning you don't have much of a delay waiting for the boost to pick back up.
Have a look online, also on the golf forums, make your own decision.
Depends on how much power you're running. Higher the boost the better it is at holding it than the standard oem part. It's louder than stock if you have an open filter.
If you've got the DV that is a diaphragm rather than piston these are prone to splitting causing boost leaks. Depends on what your setup is.
Mine is a mk3 280 but stage 1 running 360 bhp and 535 nm I get the feeling some times like not getting full boast
My Cupra came with a Rev D (on the Cupra it's at the top of the engine bay so you can check with a dentist mirror which rev). I swapped to the G and felt a much sharper response from it. The D showed no signs of tearing. But it's also worth keeping in mind I swapped a 6 year old rev D for a brand new G. So that would also have made a difference.
Hi my Cupra has only done 24k it’s a 65 plate running 360bhp and 535nm is it best to take off and see if it’s got a hole in it first before I buy new one
Hmm, I would hold off for the moment. We are talking about on the 2009-2012 models. I would have thought by the time Seat got to MK3 they'd have sorted it. They changed the dreaded camfollower to roller follower after all. Personally rather than spend money on a dv valve. If you suspect you are lacking boost, I'd book it in for a dyno run (at lot of places do it for around £30), scan for codes or have a smoke test (also around £30).
It’s going to more bhp ltd in stoke to my mate Jason he said bring up and put it on rollers I have not long fitted a full racingline r600 induction kit on it too he said it mite need a little adjustment on map as it’s getting more air and stuff will see tomz what happens lol
