Horses for courses. No one enters an F1 car into a noise/fuel-economy race.

BTW. Just in case anyone is confused, I don't work for Thermochill, and I'm not a radiator manufacturer. I just put my hand up to provide input to benefit the greater community and target their needs, and Thermochill/Marci was the only company prepared to listen. I am extremely loyal to TC/Marci though, I won't deny that. I see them as one of the few manufacturers who do actively listen to the community.
Though in F1, fuel economy may make the difference in terms of holding on to pole position in between pitstops, and the minute gains, even seemingly insignificant, can make the difference between winning or losing.

10KG more = 0.14 sec lag.

The higher air pressure drop against the radiator will slow down the vehicle and/or reduce the necessary airflow needed to be converted to downforce.

The Audi R10 won Le Mans largely on its ability to minimize fuel stops. Now if they can only get the injection system to be more reliable, they would increase that advantage.
