So....I've been looking at and giving more thought to small radiators. The size of a Honda Civic radiator wouldn't be a deal breaker but I saw another post, maybe on this forum(?), about using a Honda Goldwing motorcycle radiator. The approximate size of the Goldwing radiator is about 11" X 14" with a thickness of about 2 1/2" and has 1" inlet and outlet fittings. Thoughts on using one of them with an electric pump (or maybe a regular aluminum pump?) and an electric fan with a mild 305 Chevy carbureted on gas? Using an electric pump would have the benefit of running it along with a fan on the radiator to cool down between rounds. FWIW, I plan to run only 1/8 Mi. tracks.
I'm getting ready to build mounts for radiator, battery, fuel and "puke" tanks, so would like to position everything just once.
