Official testing ahead of the 42nd annual Westernationals concluded yesterday at Perth Motorplex with Andrew Sutton and Lee Bektash leading the way in Top Doorslammer and Pro Stock respectively.

Sutton was one of the few Top Doorslammers in pre-testing to tame the hot surface, with a 5.99 reward for the Northern Territorian's efforts.

Queensland's Ben Bray managed a 6.01 second lap out of his Sidchrome 440 Holden Monaro as teams built up their data reserves for this weekend's third round of the championship.

Lee Bektash proved his Dodge Stratus still had some life left in her, the car attending its last event before a new Dodge Avenger is imported from the USA. The factory-backed Mopar team produced a 7.11 at just over 305kmh.

ANDRA Pro Stock points leader Jason Grima has announced that he will be fielding a two car assault for the first time at the 42nd annual Westernationals at Perth Motorplex.

Grima will steer the 'black' PC Group Ford Mustang while US racer Brandon Huhtala will make his Australian Pro Stock debut in the 'blue' Mustang.

Huhtala, a resident of Seattle, Washington, is no stranger to Australian shores, having spent time crew chiefing for Grima and also winning the 2012 Nitro Champs in the Super Stock category when he drove for another local team owner.

Wayne Newby confronted the scene of a dramatic crash in April 2012 to come back and win in Top Alcohol at the Aeroflow Summer Speedfest on Sunday.

Ten months ago Newby was left with a written off race car following a 200kmh impact with the safety barriers, but this time he left with the ANDRA trophy and the first win since shifting into his new JBS Tools funny car.

When his car began to spin the tyres in the final, Newby says he had a flashback to his crash.

"It was playing on my mind, especially in the final there when it started spinning the tyres again," he said. "I was nearly to the point where I was going to get off the throttle but you can feel the funny car moving around better than the dragster.

For Darwin drag racer Scott White, contesting the ANDRA Pro Stock Motorcycle Championship has been no easy street.

White is located in the Top End of the Northern Territory and as such has to travel long distances to contest the championship. A trip to Sydney with the 300kmh motorcycle can take up to four days.

Then there is the frustration of dealing with one of drag racing's most finicky vehicles. White opened his season in difficult fashion, with parts failures holding back the AMPAC Advanced Warning Systems team from showing its true potential.

Recent testing at Portland's South Coast Raceway in Victoria produced a better result, with White setting a new track record for bikes at 4.729 seconds on the eighth mile venue.

The Clipsal 500 won't be the only major motorsports event in the City of Churches this month with the running of the Aeroflow Summer Speedfest at Adelaide International Raceway this weekend, February 23-24.

The Aeroflow Summer Speedfest features national ANDRA championship rounds for Top Alcohol, Top Bike, and Pro Stock Motorcycle plus the first running of the Aeroflow Sportsman Drag Racing Championship in Adelaide since 1999.

Over 170 team will be attending the event from all over the country, bringing an influx of racers and their pit crews into the region.

The resurgence of Adelaide International Raceway has brought many South Australian drag racers back into the sport, the latest being Top Alcohol dragster driver Frank Intini.

Intini will be campaigning his dragster at the Aeroflow Summer Speedfest this weekend, February 23 and 24, bringing along a special cause for the ride.

The Duchenne Foundation (www.duchennefoundation.org.au) will take pride of place on the side of Intini's 350kmh race car, spreading the message about Duchenne Muscular Dystrophy, which affects many young people Australia wide.
