I wonder if this is an ITG trait as I have an ITG intake for my TSi Octy vRS and that has the annoying whistle sometimes. Initially I thought I had done something as it only started doing it after fitting an S3 cooler. But even reverting to standard and fitting neuspeed turbo discharge and intercooler pipes, along with refitting the S3 cooler didn't stop it.

I drove 530 miles today and at no time did I hear the infamous 'whistle' from my Twintake (on K03).

I hear plenty of the 'whipping' sound whenever I lift my right foot but no 'whistle'.

Something i have noticed going from stock to twintake and back.

My car would sometimes spike to 20psi (stage 1 APR), i could not get the car to boost consistently. All over the show.
Now i'm on stock intake again, i never see more then 16psi other then 6th, sometimes gets to 18psi. Running APR boost tap with PCV block off.

Took mine apart just now to have a look....and the filters are wrong way round!



The inside of the filter is where the air has been coming in which is contrary to how most open cone induction kits operate (which this basically is but with a carbon canister housing)

So I'll be ordering 2 new filters then!

I thought that was the correct way, I.e opposite to the normal way?

Well RR got clarification that airflow should be like this



But on mine air is going thru the inside of the cone filter, so in total opposite of the flow diagram above

Somehow still works and performs tho. Side filter doesn't really do much judging by how clean it looked

Ta. For some reason I thought it was confirmed the other way round. But I have been distracted watching the ladies beach volleyball  :drool: :grin:

Getting back to more important matters, lol, does the incorrect orientation affect performance, etc in any way, shape or form??

When Robin's car was dynoed there were minimal differences with regard to filter orientation.

....The orientation was discussed earlier in this thread and I also corrected my original first post accordingly. It should be as the diagram and as 'conventional' to cone filters.

Performance is not significantly effected by filters being orientated the wrong way around according to both Forge and my JKM dyno runs.

IT'S VERY IMPORTANT NOT TO CORRECT YOUR FILTER ORIENTATION ONCE DEBRIS HAS BEEN COLLECTED - APPLY TO FORGE FOR REPLACEMENT DUE TO THEIR ERROR IN EARLY INSTALLATION INSTRUCTIONS.


Somehow still works and performs tho. Side filter doesn't really do much judging by how clean it looked


....I'm not sure that the relative lack of debris in the side filter means that negligable air is being taken in. Certainly the volume of air will be less due to position but I suggest that perhaps more of the debris flies past, but I'm just thinking aloud about this aspect.
