Sydney's Eastern Creek Raceway has been inundated with interested entrants for its first-ever eight hour endurance race.

Strong interest in the race has seen the event moved from November 20 to December 11, allowing competitors committed to other racing events time to prepare for the showroom showdown.

The Eastern Creek Eight Hour will attract new and existing competitors from the Australian Production Car Series, including marques such as Mitsubishi, Subaru, Toyota, Honda, Holden, Ford and Nissan.

The Eastern Creek Eight Hour will also round out a big month of motorsport for New South Wales, with Homebush hosting the V8 Supercars the week before.

Eastern Creek Raceway promoter, the Australian Racing Drivers Club (ARDC), is in discussion with the NSW State Government about the eight hour event, which will focus on being a family-friendly race event.

The event is slated to become an annual race attracting competitors from the South-East Asian region.

ARDC is also proposing a novel spectator entrance fee designed to make top-level motor racing accessible to families.

Entrance to the circuit will be just $20 for every legal car load of people.

ARDC Chief Executive Officer Glenn Matthews said that the Eastern Creek Eight Hour would continue to cement Western Sydney's importance as an event and tourism hub.

"Western Sydney is an integral part of NSW's business and tourism sectors and Eastern Creek will continue to play its role in attracting various events to Western Sydney," said Mr Matthews.

"Just this year it was revealed that Western Sydney bought over $1.6 billion into the New South Wales economy. Events such as the Sound Wave, World Time Attack Challenge and Muscle Car Masters, held at Eastern Creek, contributed significantly to this figure.

"The Eight Hour will cement Eastern Creek's importance as Sydney's only permanent motor racing venue and as a significant contributor to Western Sydny's economy," said Mr Matthews.

"Initial interest in the Eastern Creek Eight Hour from local and international competitors has been very promising - a field numbering 40 entrants is very possible," Mr Matthews said.

The Eastern Creek Eight Hour Endurance Race will cater for Production-based Touring Cars complying with CAMS 3E Regulations, and will also cater for FIA Under-2 Litre Group N Asian and New Zealand-based Production Cars.

Racing on Saturday will also feature a national round of the Radical Sportscar Championship with a two hour endurance race.
