A comparison between K04/RS6 hybrid and Tial 770R turbos on the same built 2.8l engine. Logs taken on days with similar ambient air pressure and air temperature and the same water/methanol injection on 91 octane at 5,280ft.
Over the course of tuning a K04/RS6 equipped Audi B5 S4 2.7T I have acquired hundreds of logs in a variety of different ambient air temperatures. Organizing the data demonstrates the effect of intake air temperature (IAT) on engine performance.
Far from a gimmick application, Force has been developed by a team of computer scientists and automotive experts to be a useful diagnostic and performance tool.
