At the beginning of this year due to me being at the right place at the right time, I got the opportunity to buy one of existing S2Forum member Kiku 1990 Audi Coupe Quattro without engine and gearbox.
My goal with the car was to cross the "magical" 300km/h @ 1mile speed and after that a 10s pass @ 1/4mile.
Kiku had already put a lot of work into the body, suspension and interior part - now the only thing the car needed was a engine/gearbox combo to match the rest of the awesome work. We started discussing this before me making the purchase and I gave Kiku basically the choice to choose all the components that will go into building the powertrain part and also to put everything together and supervise / help me in the future with the car. I still have ALOT to learn from him but I am slowly getting the experience. Most of the wiring work / Maxxecu installation work is done by me but not the tuning part.
Let's get to the interesting part now.
These are the current car specs of the car - there is alot more done to it and if anyone wants to know more I am happy to respond.
Here is the dyno sheet and video of the pull. Car is running on E85 and 2.9bar boost.
Measured KW / NM from the wheels.
A small video I put together after dyno day:
Yesterday I successfully competed at a local Estonian event called "One Mile Challenge". The final result for the Coupe was 315km/h @ 1mile so one of the goals is already achieved
Unfortunately I forgot to start the recording on my interior GoPro so sadly there is interior footage of the run
I will soon add a video of some exterior videos of the run.
There is much work and upgrades to be done for next years One Mile challenge, for example:
For me to start "hunting" the 10s pass, it needs stronger axels and for me to start practicing flat-shifting
It currently has S2 axels at the front and 7a OEM ones at the back. I am 99% sure that they will break the first time I will try to leave with launch control.

- Rollcage (probably will go with removable half cage as I want to keep the full interior)
- Racing seat, harness and neck support
- Parachute
- Fire extinguishing system
- Water-meth injection

and no footage from inside of the car.
