|Airflow management is critical around any racecar and the FXMD NSX is no exception, let us take you around the various vents and scoops and let us tell you what they do. You will appreciate what a complex car this is and what sort of measures need to be done to make sure a high powered turbo car can live under pounding track conditions for a long period of time. The NSX has a wide body kit to cover the huge wheels and tires, but this is no ricy unit, all the scoops and stuff actually work! Air is taken from the leading edges of the quarter panels.
|The air is routed through heat exchangers on either side of the car. One side cools the oil, the other cools gear oil pumped from the transaxle.
|You can see the heat exchangers when you poke your head into the exit ducts at the rear of the quarterpanels.
|These submerged ducts are called NACA ducts. They were invented by NACA, the agency that later became NASA as a high pressure and low drag scoop. The NACA ducts are located in the belly pan right before the rear diffuser and they take in air to keep the lower part of the engine compartment, where the exhaust system is cool even though it is completely covered by the lower diffuser. This keeps things in the engine compartment from getting hot and cooking off.
|These NACA ducts feed air to the engines air box and the heat shroud around the turbocharger.
|Two NACA ducts, one on top of each quarter panel feed cooling air to the rear brakes. A mid engine car with more rear bias works the rear brake harder than your typical car.
|Air from the large front nose inlet is vented out of the hood through a shaped duct that reduces drag and increases downforce from the splitter. The air passes though a heat exchanger for the engine’s water to air intercooler and the engines front mounted radiator.
What is in store for the cars future? Further refinements to the cars aerodynamics will nearly double to downforce and additional development of the engine will get more power. With continuing development and innovation, the FXMD team is determined to stay on top of North America’s time attack scene for some time to follow. Stay tuned, we will closely follow the course of the Teams efforts.
