    Are you optimistic or pessimistic about the end of the world?

      Not a race car, but it does get on the circuit.

          I purchased the Cheetah last year after coming to the conclusion that trying to make a family car like my XB quick around the race track isn't a wise move.

          My race car is the last of seven mk7 Cheetahs made by Brian Shead to race in Australian Formula Two. Brian designed and constructed his Cheetahs in a small factory at the rear of his home in Mordialloc, Melbourne. All up Brian manufactured almost fifty Cheetahs. The mk7 was originally a ground effects car, running venturi like side pods to pull the car to the ground. During the mid 80's ground effects were banned and the car was converted to a flat bottom format. The side pods that are now on the car are off a Cheetah mk8. I have yet to put the car on scales, but Brian Shead said that the mk7s were the lightest of the Cheetahs. I have been informed that it weighs in under 400kg. In Australian Formula Two the race weight including driver is 510kg.

          The transaxle was made by Holinger Engineering. It uses a VW case and is similar to the five speed Hewland mk9, with most components being interchangeable, but the gear shift mechanism in the Holinger is considered superior to the Hewlands. The limited slip diff is a cam and pawl type.

          The engine in my car is a 1.6 L Toyota 2T. The 2T is basically a 4 cylinder hemi, but with an alloy head. The Toyota motor was considered to be stronger and cheaper to run than the VW Golf motors that it raced against, but it is was also down on power. That isn't to say that a 2T is not a powerful motor. A standard 3TC head flows 147/135cfm @ 0.400" lift & 28" H20. Ported they flow 190/155cfm @ 0.500" & 28" H20. A strong 2T can make 180hp and I have heard figures of up to 200hp quoted. 180hp in a 400kg car makes for a very good power to weight ratio. My car has run 1:08's at Mallala, so it's no slouch. For comparison the V8Supercar lap record is a 1:08.1, F3 is 1:06.4 and F4000 is 1:02.6

            'The ghost' - Mark at sascar dosen't happen to fiddle with that does he?

            He often mumbles about a 2T powered jigger he fiddles with & brings in little bits of it for me to mess with.

              The engine was built by Doug Veale at Cantech in SA. There are a lot of custom made parts in the motor.

                  I could take some photos. What areas are of particular interest?

                      Front bulkhead is a plate. Top rear is RHS.
                      ..

                      Rear lower crossmember is RHS as is the centre crossmember that supports the springs.
                      ....
