The South African built Revo off road racer
The South African built Revo is a perfect example of true innovation at it's finest.
It was built by one of our customers, Achim Bergmann of Thompson Racing, for the Motorite Racing team.
To quote from carsinaction.net ... "So what is revolutionary about the Revo? Simple, it is the first serious attempt at four-wheel drive Class A Special Vehicle. Power comes from an American built 500hp 6-litre engine and is delivered to all four BF Goodrich tyres via a 6-speed gearbox."
The car is of a space frame construction with a fiberglass body. Tubing is 4130 cro-moly and uses a LS2 6l V8 engine coupled to a Sadev SC90 six speed sequential.
Wheel travel is 300mm all round.The paddle shifter used to control the sequential transmission in the Revo. Due the extreme dust and moisture conditions in Dakar Rally style off road racing, a custom dust and moisture seal was fitted.
One of our Paddle Shifter units is used to trigger up and down shifts controlled by a Motec M800.
A custom made dust seal was used to seal the paddle shifter from the extreme dust and moisture conditions encountered in off road racing (see photo above - click the photo to enlarge).
Up shift cuts ignition and pneumatically selects gear, down shift activates a pneumatic clutch, blips throttle and selects gear.. works very well.
The Revo weighs 1600kg (regulations) and has a wheelbase and track of 2990mm and 2100mm respectively.
Update August 19 2009: The Revo, piloted by Evan Hutchison and Achim Bergmann has just won the South African Absa Off Road Championship for special vehicles - an incredible feat in it's first season of racing.
