I love my meziere pump with Davies Craig pump controller. It is a great setup, the pump will run on with the car off to cycle coolant and cool the turbo down and so on. Very cool controller. I like the increase volume of the coolant system and I have my EMS set to turn fans on at 187 and they just never turn on. I do get heat though so that isn't an issue. I just think they are a nice option for track/big turbo/hot areas.
