Brown’s Camaro-Commodore Texas mission explained

WILL Brown is playing supersub for Brodie Kostecki at Richard Childress Racing in the United States this weekend.

Tonsil surgery stopped the newly crowned Supercars champion from embarking on his assignment with the famed NASCAR team at the Circuit of the Americas in Austin, Texas.

But what exactly is RCR campaigning in Texas? And why has it roped in an Aussie to compete?

The event is the final round of the World Racing League, a largely amateur competition featuring a multi-class structure based on power-to-weight ratios.

RCR has in recent years been a regular in the race – which sits conveniently outside the hectic NASCAR season – as part of its efforts to improve the road racing skills of its drivers.

Running under RCR’s Garage 57 banner, there are two Camaro-bodied, Chevrolet LS3 V8-powered machines on the event’s 83-car entry list.

Alongside Brown, the driver line-up features RCR Cup Series drivers Kyle Busch and Austin Dillon, and Xfinity Series rookie Jesse Love.

RCR also has its ex-Image Racing VF Commodore Supercar at COTA, running it in Friday practice to give the drivers extra mileage.

“We’re trying to look for ways to get our guys track time,” RCR engineer Andrew Dickeson explained to V8 Sleuth.

“(Years ago) we saw this race is in December, it kind of fitted with our schedule. At the time Tyler Reddick was driving for us, so we took Tyler and Austin down there and rented a car.

“It’s two eight-hour races, one Saturday and one Sunday, and you also get six hours of practice.

“We didn’t realise how hard it was to get a car to run eight hours, so the first car blew up motors and did stupid stuff like that. Ever since then we’ve built on it every year.

“Last year was Kyle’s first year driving for us, we told him what we were doing, he came and saw some benefit in it.

“This year we’ve actually built a brand-new car for it, which is kind of like an Xfinity/Late Model car.

“The class is governed by power-to-weight, that’s how they have BMWs versus what we’re bringing, versus whatever.

“Nine-to-one (pounds to horsepower) is the rough rule of thumb. At rough numbers we run about 320bhp at the wheels and 2800lbs or thereabouts.”

The rulebook makes for simple scrutineering.

“You finish the race, drive straight on the scales and then straight onto the chassis dyno,” adds Dickeson.

‘There’s a guy who brings his truck in with his chassis dyno and you just roll right on there. He has to jump in and drive, that’s how they get the number, and it’s pass or fail.”

Although the Commodore won’t compete in the race, its presence at COTA marks a continuation of a testing program that has taken place throughout this year.

Similarities between the Car of the Future-era Supercar and the Next Gen NASCAR currently used in the Cup Series make it an ideal machine that does not breach the US category’s strict testing rules.

Brown and Kostecki have both driven the car in US testing alongside Busch and Dillon this year.

“On Friday we’ll have both cars running and the drivers just rotating through all day, getting as many laps as we can, just working with each other, pushing each other,” said Dickeson.

“That’s the goal. The goal is for everyone to get better, whether Kyle can learn one or two things (from Will) throughout the weekend technique-wise or vice-versa, that’s a win.”
