Bigger the pulley the slower it turns so wouldn't this do the opposite??, or is my science GCSE not as good as I thought lol

So 37.69cm circumference vs 41.78cm.

Therefore -> 10% higher rpm on the water pump which means 10% increased water flow.

It sounds good.
I am not very happy with the way they look though.
Is this how they really are (photos) ?

Will the water pump be capable of surviving 10% highe from than it's supposed to run?

Show me some science that says rushing water through a radiator faster is better.
