dont suppose i'll ever find out what they flow, but wouldnt mind upgrading it. Car runs nice and cool 90% of time, but a new tight engine propably still with the odd bit of air in the cooling system, the 25+ ambients and standing in traffic for an hour are stretching the fan. It doesnt over heat as such, but gets towards top of temp gauge. I can't increase in diameter, but can in thickness. Any recommendations?

Rick.
