UK-POLOS.NET - THE VW Polo Forum

Hi recently purchased the forge splitter valve, http://www.forgemotorsport.co.uk/media/USASPLTR.pdf heard some bad press bout it and some good so i though i would give it a try! Well its a good valve but only on fully recirculate setting otherwise it causes a bit of lag, and fooks up ya mixture a tiny bit! So yes its a good valve cos you can set it to whatever boost you need as the spring is fully adjustable, so no new springs needed wen ya go to stage 2 , but on our engine its not too good! on, either fully atmospheric (Kept going into limp) , or splitter , and takes ages to set up without a vag com, or boost gauge ! So my conclusion is , get it if you want a valve that can be fine tuned to your boost level , never needing to change springs etc, but not for any extra sound , as dumping any to atmosphere is a no no heres how i have it set now and its really good! Oh and a tip if you wanna make your whoosh louder and you have a cone filter, remove the sound proofing from your bonnet and its alot louder, and saves on weight lol

yer mate, didnt you read some of the threads on here about how hte vag 20v engine cant cope with blow off valves they need fully recirc valves

i was gona get that one but i heard it on some youtube vids and the noise stated to become an annoyance

i did read it but im one for proving it myself LOL , its a good valve wen used like the fully recirc one , fully adj too
