It is the second championship in a row that McGrath has won and with the highlights reel also including a Westernationals victory in March, it is a season McGrath is happy to call his most successful.

“We started out the season playing with the car a bit to see if we could make it quicker,” he said. “But then we started doing alright in the points and decided to leave it alone.”

McGrath drives an Altered-style race car powered by a supercharged small block Chevrolet engine. It is covered with a fibreglass Fiat Topolino body and is capable of covering a quarter mile in 7.3sec. at 280kmh.

McGrath cited a focus on his driving as a key to success.

“You don't need to walk around with a handful of tools all the time,” he said. “We were leaving it as it was for consistency and keeping good parts in the engine to make it reliable. Realising we could go back to back with the championship was a nice thing.”

The game plan will change for the Auto One-backed drag car next season with a move to a big block Chevrolet motor to step up the horsepower the team has at their disposal and provide something of a tuning challenge for the pit crew.

“We want to go a bit faster and this package should put us into the 6sec. zone at over 320kmh,” McGrath said.

He can not see himself leaving the ranks of Supercharged Outlaws any time soon.

“Outlaws is great, we know how to race there and we can do it on our budget,” he said. “It's a fast growing group with some tough competitors and we love that pressure.

“I don't really want to be racing in a category that requires major parts to become consumables.”

McGrath has a good standing in the national championship also but unfortunately will not be making the trip to the season-ending Winternationals in Queensland.

“It's kind of a shame but I've just started a new business and to race in Queensland would cost anywhere up to $12,000,” he said. “The new motor will take time and money too but it is going to be about the team having some fun and a new challenge.”
