Typ 940

1980 Parnelli-Porsche Typ 940 Indy CarIn 1978, Porsche reached an agreement with Interscope Racing to enter the 1980 Indianapolis 500. Dr Porsche was swayed, a little reluctantly, and the project was given the green light. Work started on the engine, the major changes a reduction in capacity from 3.0- to 2.65-litres to fit in with the then current Indycar regulations. And one of the KKK turbochargers had to be binned, the rules only allowing for a single turbo. It developed around 470kW at 9000rpm and 559Nm at 6400rpm. A four-speed manual gearbox sent drive to the rear wheels. An Indy 500 qualifying simulation at Ontario Motor Speedway (which was actually in California, not Canada, and identical in distance and layout to Indianapolis) saw the Interscope Porsche post a four-lap average of 307km/h.
