First of all , thanks for the answers and of course the sexy legs 😃
About the gallons of water with a mechanical Pump:
You do Not need this!
We have Drift Cars and street Cars ( Most of them with whipple charged Ls7 engineer) with only one Davis Craig Pumps and this works perfect.
Even I think that Georg Pence have written in a old thread that the Waterpump is inefficient abouve 3500rpm because the water pass to fast the Radiator. The only Point is : how could this thing works in a Cleveland? Normaly I would say : Close the Bypass and it should Work?!
But I know some Mustang drivers smoked theire exhaust valves , so I am a little bit affraid to try it.
Joules : yes it works perfect in combination!
