New physics changes and balancing by VAC 2023 (v1.2)
Engine: Porsche 935 F6 engine enlarged to 2.8 litre with twin-turbo good for about 700 hp at 8000 RPM on maximum 1.8 bar boost, mated to a Porsche 920 type 4-speed transmission.
The successor Porsche 956 was introduced in 1982 after the new 2650 cc engine designed for Indycar was tested in the 1981 winning chassis 003 which was sponsored by Jules, a Christian Dior fragrance for men. At the inaugural year of the new Group C formula which the 956 was built for, privateer teams such as Kremer Racing and Joest Racing had to wait until 1983 for their 956. Thus, in an attempt to conform to the new Group C regulations, both teams built new bodyshapes that incorporated a roof onto their 936-replicas. Joest's car was designated as 936C JR005 while Kremer's car became known as the CK5 01.
The Porsche CK5 car by Kremer used a modified Flat Six 935 2.8 liter engine with a twin turbo. At 8000 RPM it was capable of 630 hp at 1.3 bar boost in race trim, up to maximum of about 700 hp in qualifying trim using maximum boost pressure of 1.8 bar. The power went through a 4-speed manual transmission Porsche type 920 developed for race cars such as the 917/10 and the 917/30.
