Last Year Project 370Z received some much needed cooling modifications thanks to CSF race radiators. Their single pass/higher capacity radiator and AC condenser combo made for improved water cooling and retained the factory AC performance. But as the year went on into the hotter months during summer, water temperatures started to again fall victim to over heating. The 370Z front end design only has one opening for radiator air flow. So from the get go the top half of the radiator's surface area does not get fresh air. On top of that, I have an external oil cooler taking up the left half of that single opening. So even though the CSF radiator is a large improvement over the OE unit, there is still alot of factors working against it. Top it off with 90 to 100+ degree summer track weather in SoCal, an engine known for high heat production and decently quick pace on track with a significant amount of time spent at wide open throttle, you have a recipe for overwhelming the cooling system. There were a few things we tried before the CSF triple pass unit was implemented though.
