Just fitted a RCM induction kit and i have a question. Is it supposed to sound like a Dump valve? When i lift off ? Not really a fan of dump valves but could live with it if its supposed to sound like that.

Thanks.... Will have to get used to it. But my son got a WRX and says he will have it if i dont want it, so i guess it cant sound that bad...

I currently use a Hyperflow cold air induction and with the filter hidden down in the inner wing it's still very noticable. Like you, I'm not a fan of the VTA sound (think it's an age thing?) but it's not too loud and you get used to it!

I have an RCM kit and get the sound, is there anyway of stopping this without removing it?

Any aftermarket induction makes that noise when you start removing the fender and snorkus. The sound is likely to be the recirculating DV, should be more of "chhh" sound than a "whoooosh" chav valve sound anyway! I suppose it would vary on the amount of boost and DV used. If you are completely DV less then you would hear the Turbo Chatter aka "Stall" much louder with an aftermarket intake

dont forget think you should have a remap after fitting a induction kit

I hope not, i just had a remap and decat 3 weeks ago, dont think the Mrs would be happy if i spent much more on the car. Have to watch out for the postman when he delivers my next credit card statement.

Defo needs the map checking.

+1 -

Its not worth risking running without a map tweak tbh

I'd also drive off boost until it's checked.

with a 3 port boost solenoid.

Any mods like these will need the map amended

She'd be more annoyed if you had to put an engine rebuild on that credit card! Check map asap

I can clearly hear my recirculating dumpvalve through the induction kit.

And yes, map tweak is needed

Recirculating DV with RCM induction and K&N filter. Running maffless, AF20g etc.
