Reply to "Rear Mounted Radiator"

The only problem with the long coolant tubes is they increase resistance to coolant flow which in turn increases the likelihood of cavitation at high RPM. If you want to counteract this, you can add an electric booster pump at the outlet of the radiator. I used a Stewart because if it fails, it won’t restrict coolant flow. There are other mods that help, such as increasing the size of the coolant tubes from 1-3/8” to 1-1/2” and using a single pass radiator. George Pence’s self bleeding mods work well too. That being said, all these mods do is add headroom. A stock cooling system with all the correct parts and properly maintained will cool just fine!
