Cooling System
Finally got my build "done". Went for a 30 mile drive (split in half), 90-98* ambient, and water temps hovered 215-225* with the header on highest setting trying to shed heat.
Iron block, Iron head, Cometic MLS gaskets. Block is half-filled (I asked for 1/4 fill, machinist didn't listen). EFI.
It took 9 minutes for coolant to go from 90* to 212*.
After an hour of cooldown, it went from 245* (heat soak) to 185*.
It took 9 more minutes to go from 185* to 235* then came down to 228*.
It makes 6 pounds of boost at 3000 and 10 pounds at 6000.
I'm going to add a Craig Davies booster pump (9051) in the heater hose line to recirculate with engine off. But is there anything I can do with the primary system?
I'm going to fatten it up a little in the EFI tune and considering adding water-methanol off a RPM switch at 3,000 with a 2GPM nozzle at the blower and 1GPM in the hat.
It has a 180 thermostat with three 1/8" holes, and an AFCO aluminum radiator.
I'm just not sure what else I can do?
