Thanks RR
I love the idea of an external tank cooling circuit. Do you take it below ambient temperature to take to the line?
I am assuming those are US gallons so if my math is right your water tank is potentially 24 inches by 13 inches x 13 inches or a combination thereof to ~ 4,000 cubic inches and therefore weighs 150 lbs. I guess if the car had an electric water pump switched via the engine temp it could draw from the resevior as required and won't raise that volume of water to boiling point in the few minutes of running(?). Is that why you run unpressurised or is that a flat head thing?
A friend has a V8 60 in a small '50s British classic / hotrod that had over heating problems - tried fans, tried shrouding and all sorts and in the end a bigger radiator core nailed it - even when towing the teardrop.
That would be a far greater volume of water than a rad in tank too - is there a risk of running too cold or does the engine thermostat take care of that - I can imagine it cycling a little with that volume of water?
So it's 2 pints per
68 times to make 136 pints in total (17 gallons - or do you run water in the tank - I guess you guys dont drink warm beer?)
