Looking at how to go about the coolant plumbing on my track car thats rocking a 7a with a 20v silvertop, ive looked at the 'normal' ways of do things, remote thermostats, shaving coolant fins ect...

Now ive found this davies craig water pump that has a vairiable flow rate alowing for it to act as a thermostat aswell, now on paper these sound good but id like to know if anyone had experianced these things first hand or know how well they do their job as both pump and thermostat.

Cheers
