Keeping a hill climb turbo rotary cool

[Tanj!]

Something that hasn't been mentioned is ceramic coating. I know that Swaintech has a black body coating for radiators, intercoolers, etc that increase the heat dissipation. It's also used on the cold side of turbos. You can also gain some benefits from insulating the exhaust manifold and hot side of the turbo along with the downpipe. Also look at including an oil to water heat exchanger. That way you tie your oil and coolant systems together and are able to increase the volume of your heatsink and increase the cooling area. If you wanted to go the extra mile you can coat the exterior of the engine housings to either dissipate or hold in heat. I don't remember which Swaintech recommends.
