Also, Quoting the owner of KOYO, "Dual-pass radiators work efficiently at high speeds in certain race-prepped systems, but do so at a cost of increased load on an engine's water pump, and inefficient low-speed cooling capacity, which can raise pressure and temperature to higher-than-desired levels."
ORLY?.
My Normal Koyo would see temps of 90C in traffic(bumper to bumper). With my N-flow I DO NOT see temps above 80C. The N-Flow is hands down a better radiator.
This is in south east GA right on the coast. Its 90F+ almost every day with 100% humidity. More then half the summer has been a heat index. In fact, Just yesterday the thermometer outside my house said 106F.
