Cosworth: Next two bigger test for engines.

Cosworth believe that the combination of Bahrain and Imola could be a much bigger test for engines, than Melbourne and Kuala Lumpur.

Talking on the eve of the third race, David Prigg revealed that although Cosworth had no problems during the first two races - despite the fact engines now have to go twice the distance, the next set of two could be a different question as they will be much more demanding. All this could spell bad news for Red Bull Racing who depend on the 'Ford' power-plants...

"Both Melbourne and Kuala Lumpur GP engines have now been inspected at Cosworth," said Prigg. "The engines were in excellent condition following their double points scoring finishes.

"Cosworth anticipate though that the combination of the Bahrain and Imola circuits to be more demanding than Melbourne and Kuala Lumpur and the challenge is to run competitively and reliably at these events and to ideally maintain Red Bull's points scoring record."

Red Bull technical director, Gunther Steiner is aware that Bahrain could be a problem and as such they will be taking special measures to ensure that the sand doesn't get into the engine.

"Not surprisingly for a desert track, sand is the main story and you have to be aware that it can get in to every part of the car," he warned.

"It literally sandblasts the car every time it goes on track and gradually erodes all the surfaces and the cooling fins on the radiators.

"I gather there are some modifications to the track for this year, aimed at minimising the problem. The main challenge is to ensure you do not get fine sand into the engine and so we pay particular attention to the way the air is filtered before getting into the engine. It's especially important this year, given that the same engines have to last to the end of the following race."
