Reply to "Clevor remote thermostat options, Stewart water pumps."

Thank you David for this alternate approach. A stage 4 mechanical pump and a 55 Gal booster that is a lot of pumping going on. Do you run this set up with a single pass radiator and did you run the stage four pump on its own and find it necessary to add the booster pump or did you install everything together?

EMP Stewart kindly sent me flow charts for the stage three and four windsor pumps. The stage 4 flow is certainly impressive.

Regarding George P.'s cooling tank mods, we run this very same combination of swirl pot and header tank on our 2 litre toyota race engine currently putting out about 450hp. The radiator and swirl bleed directly to the header tank, which in turn feeds the water pump inlet. Up to now no cooling problems and this engine gets pushed very hard. I would say it is worth the mods just for the ease of filling and purging air from the system.

John
