FORMULA-R SPECIFICATIONS

Formula-R is a category designed to provide a place for "Classic" F3 and F2

chassis to race together with fair rules, parity and reduced expenditure.

Australian Formula 2 ( Aluminum Chassis, Pre 1990 )

As per original specs Carburetor 1600cc SOHC @ 8500 rpm, Min weight 500kg

Alternatively *Carburetor 2000cc @ 7000 rpm, Min weight 500kg

Post 1990 F2 chassis add 25kg if fitted with 2000cc engine.

Australian Formula 3 ( Carbon Fiber, 1990 - 2001 )

Fuel injected 2000cc - 26mm restrictor @ 6750 rpm, Min weight 550kg

Fuel injected 2000cc - 24mm restrictor @ 6750 rpm, Min weight 500kg

Alternatively *Carburetor 2000cc @ 7000 rpm, Min weight 550kg

The intention is to allow engine/chassis options that give

owners leeway to use cost effective engines in place of more expensive

legacy designs. For example, either a F2 or F3 chassis can be equipped with

2000cc production engine utilising carburetors for reduced cost and complexity.

Chassis Min weights are used to help balance the aerodynamic advantage of post

1990 chassis and/or power considerations.
