Sydney driver wins Lismore Sprintcar Gold Cup
Loudoun, who started from position six in the 35-lap final, raced into the lead mid-race and was never headed as he led three-time Australian title-holder Max Dumesny and Adrian Maher to the chequered flag.
It was a race full of drama almost from the drop of the green flag.
Sydney star Sam Walsh started from pole position and was hot favourite after a peerless performance in the heats, but his race was run after just four laps when he crashed out.
This was due to smoke that drifted across the circuit from fireworks released at the start of the event.
In the heavy atmosphere, the smoke had not cleared the circuit and race officials were set to throw a yellow light moments before Walsh crashed, with vision for the drivers reduced.
He escaped uninjured, however it was an unfortunate end after Walsh was clearly the dominant driver.
Walsh had earned his start from pole position after winning the pole shuffle over the top eight qualifiers.
He recorded the fastest time from all heat winners when he set a lap of 11.01 seconds and also notched a two-lap track record (23.249s) when he won the final of the pole shuffle.
When the race settled down it was Mark Blyton who set the early pace, chased hard by Darryl Campbell and Loudoun, Michael Matchett, Adam Tulloch and Brisbanes Bryan Mann.
A yellow light was thrown with 17 laps remaining after a spin in the main straight by Steve Caunt.
When the race resumed Loudoun pressed his claims for victory. He move around Campbell and set after leader Blyton.
Loudoun pressed Blyton for several laps before he made his winning move in the latter half of the race.
Dumesny also drove into contention after starting from deep in the field. As the race unfolded he moved through the traffic and with 12 laps remaining ran into third.
He later passed Blyton for second, while Adrian Maher also came from deep in the pack and was the most impressive performer in the last 10 laps.
He moved into fifth, then overtook Campbell and Blyton for a well deserved third placing.
It was an excellent result for Sydney's Bevelite Glass team, which provided the winner and third placegetter.
The top 10 were rounded out by Blyton, Campbell, Thompson, Kelly Linigen, Roddy Bell-Bowen, Steve Caunt, Adam Tulloch and Michael Matchett.
The inaugural Lismore Sprintcar Gold Cup was one of the biggest meetings in the recent history of Lismore Speedway and promoter David Lander was rewarded with a capacity crowd.
