In late 1985 Porsche developed the 944 “Weissach turbo cup race car” to provide amateur enthusiasts with a cost effective entry into motorsports. Porsche initially designed to participate in a single-marque racing series run in conjunction with 1986 German ADAC Supercup races, but soon spread to Italy, Spain, Belgium, Austria , USA, Canada and even Czechoslovakia. The cars were modified extensively for racing duties, including taking out a lot of weight.
In 1981 Porsche developed two 944 prototypes to succeed the 924 GTPs which raced the 1980 24 Hours of Le Mans. To coincide with the release of the 944 in fall of 1981, Porsche prepared a GTP version to promote the car before the launch. The GTP was equipped with a special Type 949 cylinder block with dry sump lubrication, KKK K28 turbocharger and an air-to-air intercooler.
