Free flowing Charge Air Cooler (CAC) – or intercooler – design with streamlined external air passages improves engine cooling while offering less fan noise and less blade resistance plus improving engine power and efficiency of the radiator and air conditioning heat exchangers. Designed through testing at 100+ psi turbo boost pressure and 500F turbo outlet temperatures our extra thick cast end tanks with support struts have integrity and long life without ballooning and cracking. Micro Extruded Tube design is for applications producing 20-100 psi of boost pressure and inlet temperatures of 500F+. The tubes have a 0.025 wall thickness and designed enhanced inner fins that add to performance and already strong support structure resulting in a 95% heat conductivity transfer. No cracking or separation occurred when tested at over 400 psi. BDs Cool-It CACs are designed for performance diesel engines.
