SUPERCARS will light up Sydney Motorsport Park (SMP) in its entirety after a top secret test confirmed all 3.9km of the Eastern Creek track could be safely floodlit for a history making night race.

The Saturday Daily Telegraph can reveal the “SMP SuperNight 300” will now use the full length “GP Circuit’’ in a Sydney spectacular after Supercars lit up the Western Sydney track on Monday night for a surprise test.

In a successful bid to see V8 night racing make a fully-fledged return after a 22-year Australian absence, Holden star James Courtney was turned into a test pilot to put the full SMP circuit through a night exam.

The Big Bash inspired short format V8 event was scheduled to run on a 2.8km version of the full 3.9km SMP track.

Supercars confirmed on Friday night all 11 corners of the track would be lit up for the two night event, beginning August 3.

“The full circuit will look absolutely incredible completely lit,” said a spokesman.

“We have sourced enough broadcast quality lighting to do the full track which will really add to the spectacle at the track and on television.

“The test was focused on the ability to get a better reach and spread of the light, which has to be suitable for broadcast, drivers and officials.

“The light system not only works well for illuminating the track, but its range and throw mean braking areas, signage and the general vicinity will all be well covered.”

Courtney declared the test a success after going full throttle in a road going Holden Commodore.

“There were no dramas at all,’’ Courtney said.

“Everything went really well. I was actually surprised by how well I could see and the effectiveness of lighting.’’

Born and bred in Penrith, Courtney said the Australian night racing return would prove a popular product following its 22-year holiday.

The last Australian V8 night race was held at Calder Park, Victoria in 1996.

“Anything under lights looks better and racing cars will look fantastic,’’ Courtney said.

“There will be flames coming out of the exhaust and the brake disks will be glowing red. It adds a lot more drama to it all. It’s going to be great running the full circuit, we did the full circuit in the daylight and have always had great racing, so it’s going to be even better of a night.

“I think it will be an excellent event, it’s definitely going to be quite a spectacle and something very different which we haven’t done for many, many years.”

Sixty temporary light towers will be erected for the event that could pave the way for more night racing to be added to the Supercars calendar.

“It will look excellent under lights,’’ Courtney said.

“The cars really stand out and pop under the lights. It’s going to be fantastic, the sparks and scrapes we touch will look amazing on television.”

Supercars last month extended what was originally a one-night only event to two with a practice session added.

“It’s going to be very different as a race weekend and racing at night is going to be very unique,’’ Courtney said.

“I think it will draw a crowd and hopefully we can put on a good show.’’

The Supercars series returns next week with the Crown Bet Triple Crown in Darwin, beginning Friday.
