Thanks to Ian from Rennenhaus for working with me to get something to work in the TDI engine bay.
What has resulted is that we are using a Modshack R32 intake as a filter prototype. There was a complete removal of the standard intake before the MAF - and now lives in the shed. The kit that comes with the R32 model filter required only limited adjustment (ie. bench grinding for the bracket and a branch to be tapped before the MAF for the vacuum line).
The bracket is joined at the Earth connection point so the paint on the bracket requires removal.
So down to the nitty gritty;
Deciding the best location for the filter;


After deciding that the best place for airflow was inline with the grille, the following is the result;

Looking through the original air intake area;

Looks very discreet;


Location of plumbing;

Be aware - tight fit - potential rubbing;

Location of the mounting bracket;


The 1000 kilometer review:
Noise: There is a lower tone and some intake drone - nothing like the slurp of a petrol - but notable.
There is slightly more noticeable blow off sound from the waste-gate.
On the highway and around town, not a problem with the noise.
Economy:
At this stage I think there is limited around town economy increase. On the highway, I think that it is saving around .4 - .7 liters per 100 km.
Performance:
Most noticeable is that how much smoother the car is at lower revs. The main problem I had before was the VERY large delay in the lower rev range. This area is smoother and more pleasant than the OEM system.
No great variance on the soot from the rear.
Overall:
I think that as part of the intake, this is a good addition. It will assist with induction of cooler air and more of it undoubtedly.
In a perfect world I would next approach the exhaust on this car, however I am not really willing to invest that amount of money yet.
I would give this solution a thumb up - and as there are not many others out there at this stage, serious consideration if I was contemplating other mods like Chip or Exhaust.
