GP Week : Issue 76
Technical Update: Malaysian GP What small changes there were for Malaysia were generally cooling-related, reports GPWeek Technical Editor PAOLO FILISETTI AS there was just one week between the Australian and Malaysian Grands Prix, the cars didn't undergo any significant development programme, so the changes were just few. The most significant ones were mainly focused on improving the cooling capabilities of the cars, trying to extract in the most efficient way the hot air exiting from the radiators, in turn trying to maximise the reliability, engine wise, put under pressure by the hot and humid weather conditions typical of Malaysia. Other small changes also were spotted on other cars, but were just minor refinements -- a few of those already seen in Australia. In the search for cooling improvement, Toro Rosso modified the bodywork around the exhaust pipes (top right). The exhaust opening is no longer placed on the top of the sidepod -- instead now it is completely covered by a round section cover. The same principle, we can say, has been followed by Mercedes (right), which visibly changed the bodywork around the MGP-W01's exhausts. In Bahrain and Melbourne there was an additional gill linked to the exhaust opening, with the exhaust blowing upwards. In Sepang the bodywork was modified, creating a wider opening around the exhaust to help heat extraction. A change that wasn't really a new one (it was already spotted in Melbourne), is the one related to the front wing endplates of the McLaren (below). This change was in reality asked for by the stewards in Bahrain, to give previously sharp edges of the MP14-25 front wing a more rounded shape. McLaren introduced this solution in Australia and then kept it as a definitive solution. There were two different version of endplates in use in Malaysia, as it resulted as an improvement in terms of turbulence generated around the front wheels. F1 NEWS >> 14
