Haven't had much of a chance to work on my own car recently.
Changed the front and rear pads and discs.
Decided on EBC yellow stuff front and rear pads.
Front disc managed to source some EBC and rear's from ATE.

Air box mod done - OEM+ look :)

(Before everyone starts drilling their air boxes take some pressure measurements as 99% of the owns won't need this)

I'm also working on something special in the background ;)
More details to follow in the next couple of months (I hope)

July 2019

Been fours since the last car detail - special thanks to my cousin @teamspb for all his effort:

For a car with over 150k on the clock he done a great job.

January 2020

Been a while since I've done much with the car.
Some maybe aware but I bought a used engine last year with ojective to rebuild it. As I mentioned earlier in this thread the PCP are extermely high and main task I wanted to address is compression ratio. With such high pressures the heads have started to lift when using the power for prolong periods causing coolant issues. The car has 160k on it and still being driven and still performs well.

Here are some pictures of the replacement engine:

Nice to see cross bore drilling:

Heads cleaned & flattened

Valves reseated

12.9 head bolts sourced and modified to suit the Audi V6 engines

Piston work

CAD drawings are complete with CNC profile set.
If all goes to plan lowered compression ratio will add scope for more power while remaining within PCP.

R110 fuel pump finally running, as per my post in Jan 2020 I've been trying to get this pump running.
I had it running but during high rail pressure it would leak causing the Vee to become a swimming pool.

Here are some pics during the development

Custom gearbox pump plate:

Rail pressure output valve changes:

R110 pump:

Even thought about custom gears to spin the pump faster:

After long last R110 is now working without leaks.
Thanks to @Horia for his support and many others who support me through other social media sites.

Febuary 2021
Sourced a 4 bar boost gauge in preparation for some more boost Turbosmart Gauge Electric Boost Only 4 Bar
Moved the boost gauge to the pillar pod gauges and the turbo speed gauge to the centre vent.

Gauge comes with a pressure sensor which I mounted in the EGR blanking plate

Cylinder pressure tool arrived finally - Very expensive sensor:

March 2021

Been spending some time on pushing the engine further and making decent progress.
I've installed a injector current clamp and now can see the injection events per cycle:

Learning a lot from this tool for example x deg timing can add y bar of cylinder pressure depending on RPM - having big injectors is a must.

Turbo is now pretty much max (safe limit) and emp is now in the positive range, so measured the exhaust back pressure (still using the stock system apart from the downpipe) and it showed a peak figure of 450mbar.

Looking at the stock back boxes you can see Audi engineers put some thought into the design:

As a test I decided to open the second port on the back boxes:

Welded in a 90deg 57mm elbow - JEEZ wow its so loud haha totally unbearable.
End result was 60mbar drop - hardly worth the effort and rather save my ears so will be welding that back up.

Will look into the rest of the system to see if I can gain any flow, but so far I see no benefit of changing the back boxes.

March / April 2021

Well the second port got welded up:

The hunt for a exhaust solution continued objective being
  • Slient (as can be)
  • no droning
  • Good fitment

Decided on a RS4 exhaust 2 x 65mm pipe work with built in valves

Stock 3.0TDI 1x65 to 2 x 54mm

76mm to 2x65mm adaptor

Note additional mount is required for the centre box and I had the whole flexi section made in 76mm

Diffuser drama

So I wanted to go with a RS4 rear diffuser but it seems none are available for a S line model.
Went to a exhaust place they suggested pointing the inner back box tip downwards and then building a tip with suitable bends for the stock diffuser.

Somehow I didn't like that idea and after speaking with a few people I decided to so with a S4 diffuser, idea being the exhaust opening is larger to suit the twin tips of the RS4 box.
Still needed some tips and scanning through ebay I found some C7 RS6 tips for cheap money :)

Old diffuser off and vac lines for the valves ran:

As the RS6 tips are open back I tack welded the tips into the correct position and then made a back plate for both sides and welded them - tips are now stronger than the rest of the exhaust!!

Very pleased with the end result and a perfect solution for still keeping the car civil.

Purchased this vac unit for the exhaust flap control - works good enough:

So to recap the back pressure with stock exhaust was 458mbar and with the RS4 exhaust and 76mm flexi section we have 24mbar.
This resulted in 50 deg EGT drop - very impressive and gives further scope for more fuel.

The only disadvantage is weight - the RS4 with its additional centre box and larger pipes does add weight but I can live that to save my ears.

Not much has been done to the car apart boost/EGT gauge change

Can be programmed as required:

Longer probe

Custom support bracket

In the meantime for those who may not know check out my S2 thread:

Car has done now 6k @ 600hp so it was time for a oil change and noticed the front discs and pads were finished.
EBC front discs lasted 20k basically but they've been bent for a while.
This time I went with ATE from Macan turbo disc's and stuck with EBC yellow stuff pads:
