      it´s looking great, some more details about the engine parts would be very interesting.

      but also i can´t imagine that this engine could work very long, all parts from these engine are very race-optimized..

                I might be wrong but I think the new owner had a little mishap with the engine, something got wrecked

                  Nope, youre wrong I know the owner.. he has several special Audis, and the engine will soon appear on a track near you in a very special Audi.
                  Right where it belongs..

                          The IMSA head has 4 valves per cylinder but is a lot different to a normal 20v head , amongst other things it has geared cam wheels and 10 inlet ports, 1 for each valve, instead of the normal 5 .

                              Interesting dynosheet indeed. Runs quite lean, 13+ on E85.
                              Something is funky with the horsepower vs. torque numbers. At low rpm, the power is overstated, and they are understated at high rpm.
                              If it really makes 630nm at 8500rpm, it makes 761ps at 8500rpm, not 701ps as listed
