2003 RS6 Build Sheet with Dyno Results

[Del Stator]

So my car finally makes it to the dyno after a year long build process.

The Cliff Notes: 417whp and 571wtq

Here are the specs:

- 2003 Avus Silver/Ebony/Carbon Inter. 59k miles

- Build Shop: Griffin Motorwerke Berkeley California http://www.g-werke.com/

- European Performance Lab new upgraded RS6 Turbos; Custom compressor wheel and housing, Tweeked exhaust wheel, Friction work done to the shaft, modified wastegates http://www.eplabs.net/

- European Performance Lab modified fuel injectors

- Tuned by Tony of EPL remotely

- Dyno runs done in Santa Rosa, California at Fine Line Imports. Miles of Fine Line was the dyno master and loaded files, did runs and sent logs back to Tony. Subaru tuning is Fine Line's specialty. http://www.finelineimports.net/

- Wagner Upgraded Intercoolers

- Okada Plasma Direct Coil On Plug http://www.okadaprojects.com/usa/products_direct.htm

- Fluid Motor Union Intake……..and no, I don't have before and after dyno figures. http://www.fluidmotorunion.com/performance

- Full Milltek Exhaust non resonated

- STE PPD information display http://www.getste.com/

- 517 Built Transmission and TC http://517trans.com/

- MTM TCU

- Aquamist 100% Methanol Injection

- Aces IV gas treatment and Aces IV-A Methanol treatment This was mainly done to help over come in any possible way the garbage gasoline we have in California. 91 octane crap.

- Apikol Engine, Transmission and Differential mounts. Both blue and red…don't remember what is where.

- Sterns Upper and Lower Control Arms

- Bilstein PSS9 Coilovers

- Loba built AP Racing 390mm brake rotors

- Loba modified C6 RS6 (Euro) brake calipers. These calipers were on some Lambos.. I think they started using Brembo calipers later. Then they discontinued the kit and only sell C5 RS6 rotors.

- Hotchkis Sway Bars

- Hartmann HRS4-252-GS 20"x9" I wanted to get Forgelines for the car but just don't want to spend the money now…..maybe never.

- Vredestein Vorti 265/30/20 tires I got a killer deal so I thought I would try them. Some really love these tires.

- Passport 9500ci Radar Detection System

- Pioneer/JL Audio audio system We also used Dynomat inside the trunk and rear quarters.

- Stephencl Carbon Fibre Air Splitter

- I am sure I am forgetting something…


Let me say that I have not driven this car. Because of work related travel I won't be able to pick it up until the end of January. I was told it hauls ass!!

Here is the quote in the email I got from Fine Line after the dyno runs…..I was not able to attend,

"The RS6 is done. There is some partial throttle mapping I notified Tony about (with logs) but all wide open throttle is done, cold start, hot start, cruising, idle, etc. The results were great. It took lots of time but I believe well worth it. The cold start is as good as it is going to get with tuning remotely. I believe it is fine for a car with larger injectors.


Peak torque to the wheels was 571 at 2600 RPM, 417 whp at 4750 rpm with 18.5 psi tapering to 9 psi. I know you wanted 16 psi tapering to 14.5 psi but this engine / turbo combination does not warrant that. "
