Try it you might like higher trap speeds.

Ummm....wrong. The hood extractor is just that. An EXTRACTOR. It removes heat build up from under the hood that's generated by the super charger and the front stack. The frontal air now quickly moves through the stack and out from the hood with no resistance removing heat. Without the extractor you have...resistance. The pan on the bottom has very little to do with downforce and was designed to channel air for cooling. Hence the reason why it has NACA ducts directing air UP and doesn't span the length of the car. And downforce does NOT create drag. Especially on a car that has a belly pan and is low to the ground. Ironic that DRAG racing involves the nose of a car pointed at the sky and creating DRAG because it lost its aerodynamic properties with all the air trapped underneath like a scoop. The lower the car is to the ground (downforce) the more aerodynamic it becomes and the less drag/resistance that's exerted on the body. You know...Bernoullis Law. The whole reason why airplanes fly and race cars are seeking MORE downforce to REDUCE drag? Better go back to school. Try it...you might like it.
