Audi TT 1.8T BAM Stage 2

Intercooler, 630CC injectors and turbo hybrid - unfortunately with a defect

The turbo had a tendency to overload and getting the most realistic result on this setup of 300 km would be dangerous in longer use. The exhaust gas discharge was not efficient enough, which is why we had a tendency to overboost in the upper part of the revs. After longer struggles we stabilized the setup, and the recommendations are -> to let someone else do the turbocharger.
