Team Jebsen's Darryl O'Young will be hoping to stay cool in his car but hot on the track as he mounts a serious challenge in rounds four and five of the Porsche Infineon Carrera Cup Asia in Thailand this weekend. Having just been picked as one of the drivers for the SAR's Le Mans team next year, O'Young will have his work cut out in Thailand as he tries to stay cool in the searing heat at the Bira circuit, where cockpit temperatures can reach above 70 degrees Celsius. The majority of drivers use what is known as a 'cool suit' - a shirt worn under the racing suit with tubes running through it connected to a box of ice and water. The cold water is constantly pumped through the shirt, rather like a radiator. Fitness guru O'Young will use all his fitness and work in the gym to help him overcome the physically demanding races as he looks for another podium finish after coming in second in the opening round of this year's Carrera Cup, held as a support race to the Malaysian Formula One Grand Prix in March. O'Young scored a well-earned second-place finish, but was deprived of a second podium spot last month after an audacious move by reigning British GT Champion Jonathan Cocker in the last few metres of the race. O'Young finished fourth in that race but had done enough to demonstrate that he is one of the drivers to watch out for this season. The 25-year-old Hong Kong driver knows what to expect at the Bira circuit, calling it a true test of physical stamina and racing skills. 'The heat in Sepang was almost beyond physical,' said O'Young of the series's previous round. 'We race a closed-window car so it is quite different to single seater racing, and the temperatures were above 70 degrees Celsius inside the cockpit at Sepang. It helps to be ultra fit [he trains three hours a day, six days a week in the gym], but there comes a point where you need to cool your body down.' 'You only feel the cool suit for the first lap or two,' said O'Young. 'Even though it keeps doing its job, you can't feel it any more because it gets so hot inside the cockpit.' Other Hong Kong drivers joining O'Young are reigning series champion Matthew Marsh, Philip Ma, Alain Li and William E. Connor II, the 18-year-old Cocker, current series leader and Asian racing veteran Charoensukhawatana Nattavude of Thailand, and former Formula Three pilot Rizal Ramli of Malaysia.
