Anyone fitted this to their twincharge engine. If so, what are the benefits and is it worth the money?.

Forge will benefit, but you'll mostly sound like a bus discharging its air brakes. I was given one for octavia but took it off as it was embarassing. Imo it just shouts wannabe suburu.

This is a full unit swap not just the spacer so does it still make the silly noise!

 

[jc_boc]

I believe the full unit is better than just the spacer since you're increasinf power. It will still give a nice blow off noise but I believe it is more oem than the spacer.

no I tried one out on my mates Polo with him. There even louder than the spacer. The also trick the engine into thinking it has boost when it dosnt, recurc is better that is what I have.

Not after any noise just want to uprate the DV . Is there an after market alternative or do you still have the oe valve?

 

[phil_monk31]

go for the recirc valve then if you dont want any noise.

Another problem with the BOV if that these engines dont drop boost when they change gear, so it only makes noise when you take your foot off the accelerator

Thanks Phil, think i might get one of them.

 

[phil_monk31]

no problem mate....

So the recirc valve does not make any noise, is that correct !!!!!

 

[phil_monk31]

Yea thats correct.....none that you can hear over the engine any how,

Just Be Sure you got the right Spring Setting if yours is Remaped . Also a Piston valve got a tad slower reaction compared to the OEM Membran valve .

 

[phil_monk31]

the blue should be ok..... there PSI ratings on there site are bolloks.... have drive with each (yellow and blue) and see how the car feels on them.

 

[yea_good_1]

Do you notice any gains atall with it or is it just for peace of mind? is there interchangeable spring that come with it then? What would you recommend for my stage 2 on setting c Phil not sure what you run

 

[phil_monk31]

Hey Dude
Yea they come with 2 springs and if you look on their site it will give you the PSI rating of the spring, however I find their ratings crap and go on the feel of the car. Some of the high rating springs are weaker than the lower ones. there is no consistency to their construction at all.

However I am running the blue that came with it. As for gains, there is a lot better pickup at low range.

I got mine as my OEM one was broken, i smashed the face if it and cracked it.

I would recommend one as the car just feels better but I would say order the springs as well and then see how the car feels, or get some VAGcom logging done as this will show problems if the springs are wrong.

And setting C :-( you’re brave, mine is staying well away from that setting until i get a few bits sorted.

 

[yea_good_1]

Yea I've been driving it hard a lot recently and it seems to be ok going to have a think about it first I know it needs to be done got service coming up and bike needs mot just ran out lol

 

[Stevoz03]

I also have this valve and it came with 2 springs, A yellow one and a blue one. Forge told me the blue spring is the stiffer spring and should be used on remapped vehicles but if you compress both of the springs by hand you can easily feel that the yellow spring is stiffer, so im using that one.

 

[yea_good_1]

Oh fair enough so the springs come with it then or do you order seperately thanks for the info will get service done and then look at getting one of these pose to protect the engine a bit incase oem one fails what happens if the oem one fails does anyone know?
