Geoff Gradden qualified for his first Top Doorslammer field at the Australian Nationals over the weekend. He then proceeded to win the entire event.

Team Sigra Rollingstock Components from Penrith NSW went home as winners in a field featuring newly crowned seven times ANDRA Drag Racing Series Top Doorslammer Champion John Zappia, 2014 runner up Stuart Bishop, Fuchs Spring Nationals winner Grant O’Rourke, tough West Aussie competitors Pino Priolo and Marty Dack along with former champ Peter Kapiris.

In fact it was top qualifier Kapiris who Gradden defeated first in Round 1 before taking a solo pass in the semi final when John Zappia sustained irreparable damage in his own first round solo run. 

Gradden faced Marty Dack in the final and powered to victory when Dack lifted the blower in what was shaping up as a tight finish.

“We’ve been Drag Racing for 10 years, and this, our third and fastest car has been under development for 4 years,” explained team owner and driver Gradden. 

“We qualified in the eight car field for the first time on Saturday as the eighth and slowest qualifier.

“On Sunday at elimination rounds, we won against the top qualifier; Peter Kapiris from Victoria, crossing the finish line only seven hundredth’s of a second (0.070 seconds) in front.

“So we completed the quarter mile in 5.96 seconds and crossed the line at 246.71 mph – faster than the car has ever gone before. 

“We lined up in the final against Marty Dack from WA and put the car down the track for a 6.03 at 244.21 mph for a comfortable win.

“We knew we had a race car from testing, but needed all aspects of our preparation to come together, along with a few mistakes from other competitors to be able to do well at this national event.

“To go home with the winner’s trophy as a first time qualifier and setting personal best times is more than we could have imagined or dreamed of.”

Team Sigra is a part time, low budget group of family and friends. From the Gradden family – Joanne, David, Tim, Lorna, Bob and Megan, as well as long time friends in the crew, Mick Ellis, Alan Brown, Mitch Turner, Bill McDonald and Waldo Goddard.

“It takes the whole team countless hours of preparation, planning and working flat out all weekend to get the car tuned and serviced between rounds,” added Gradden.

“Special thanks also go to Maurice Fabietti and Stuart Rowland for their technical help and advice.”
