1,300 HP Corvette Travels to Australia for the World Time Attack Challenge
Feras Qartoumy takes the Pro-Am Class win at the World Time Attack Challenge in Sydney, Australia.
The C6 Corvette is an incredible performance car platform. You can keep it stock and have plenty of performance for the street. You can modify it a bit and take it to track days or even some local competitions. Or you can go all out like Feras Qartoumy did and turn the C6 into a full-fledged race car. The sky is the limit with these cars and with 28 track records under his belt already, nobody knows that better than Qartoumy. His latest accomplishment is taking the Pro-Am Class win at the 2023 World Time Attack Challenge in Sydney, Australia. He managed to put down a lap time of 1:27.0160 which was about a half second quicker than the second-place finisher.
Larry Chen caught up with Qartoumy while he was in Australia and got a walkthrough of the World Time Attack Challenge Corvette. Chen posted the video recently on his YouTube channel. In it we learn not just about the details of the build but how Qartoumy obtained the parts to use in the build. He did it almost like he was playing a video game in real life. He would compete with the car, win some products, such as larger turbos. Then he would install the larger turbos and compete and win again. He would then take those winnings and put them on the car. It is difficult to argue with the results.
Powertrain
The entire build is fascinating but this is LS1Tech so we are going to focus on the engine first. The engine uses an LSR block and was built by Late Model Engines. It has CID cylinder heads, Callies Magnum crank, rod and pistons. As it is built the long block is capable of making up to 2,000 horsepower. However, with the current tune and the pair of Garrett G35-900 turbos the car typically runs between 800 to 1,300 horsepower. The engine is mated to a 1:1, six-gear sequential transmission.
Body
The car was originally a drift car. It uses a carbon-Kevlar body from HGK. This helps keep the weight down to around 2,600 pounds. Qartoumy actually made the car too light. He replaced the Corvette rear tub with some aluminum. However, to stay within the rules for his class at the World Time Attack Challenge he needed to add ballast to increase the weight. Another highlight of the body is the air duct where the rear window in a stock C6 Corvette will be. This duct feeds air to the rear mounted radiator.
Next Steps
Like any competitive driver, Qartoumy is always chasing more speed. He is currently building a second race car. He plans to incorporate the lessons learned from his current C6 Corvette into the new car to build something even faster. Given his success at the World Time Attack Challenge and other events around the world, the competition is probably not looking forward to Qartoumy running an even faster car. However, for those of us watching from the sidelines, we can’t wait to see it.
