R8 Gordini of Adam Billiards

The vehicle has been used extensively for competition since I acquired it in mid 1992. It has been involved in three major accidents and currently is in storage since its last accident in 1998. I plan to restore it and compete in historic rallies and classic events when time comes available. The 16TS power plant has given the car a new lease on life with great mid range pick-up and performance without the need for specialised engine components. Good tuning and engine building practice has enabled reliable power and torque to be obtained. The car really gets up and goes from 3000-3500RPM. We use a rev limit of 6800RPM although on occasions (wheel-spin) 7000RPM is not uncommon. Extended periods above 6800RPM usually results in bearing failure. Gearbox life is a major problem with the sun and planetary gears in the differentials being a weak link although on one occasion a output universal shattered. I have been using a standard 16TS clutch and pressure plate, some slippage does occur on occasions but I would prefer to have this slip then to rebuild another gearbox.

Brakes require nursing in events which are particularly harsh. The adjustable bias valved help this situation by allowing the rear to perform some extra work. The disadvantage of the extra rear bias is less stability under brakes. This has however been an advantage for gravel and tight hill climb events.
Handling is OK, considering the car is 30 years old! But on the next rebuild I am thinking of adding a ‘camber compensator’ to the rear swing axles.

Overall the R8 is great fun to drive, everyone who has driven the car considers it a challenge yet very enjoyable to drive at the limit. The car also receives a great reception at events in Australia, they have a great history here but very few remain and even less are ever seen competing. Adam Billiards
