Bobby Singh's Audi A4 3.0 TDI Project car

December 2020

Gave the car to my cousin from TeamSPB who also runs a car detailing business called "Reflective Detail".
Main objective was to make a custom gauge pod for the turbo shaft speed, however while he had it he asked if I needed it back in a rush...I replied with a nervious no.
But wow he gave me a amazing surprise with a level of detail I've only read about. Im not really sure which combo of pads, wax, sealant etc he used but the job is the best I've seen.

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.

Cheers

Febuary 2021
Sourced a 4 bar boost gauge in preparation for some more boost Access denied
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:

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.

Cheers
