Personally, I liked the previous wing that I saw on your car at ALMS. This wing looks like it might create a good deal of drag. This one looks like it would negatively impact the delicate balance that Honda engineers designed into the rear wing. See
page 14 of the NSX Technical and Developmental History (the black book).
From the article:
To improve downforce at the rear, the design of the integral spoiler enhances high-speed stability, reduces yaw moment and turbulence, and helps achieve neutral lift.
Ken check out the May issue of Car And Driver. Page 54 on Ferrarri 599XX Aerodynamics Explained and the claim of more downforce without any penalty in drag from the huge scalloped trunklid ducktail spoiler.
Probably the most outrageous spoiler isn't even a spoiler. It's the tailgate mounted on every pick-up truck. It has been proven even though it may defy logic, that the drag is actually less with the tailgate up rather than down. The reason, a high pressure air bubble directly in front of the very unaerodynamic looking raised tailgate. The bubble causes a smooth flow of air to ride over the top exiting the rear of the truck. With the more aerodynamic looking lowered tailgate, there is no high air pressure area (Bubble) to create the smooth air flow, only rolling balls of turbulance which causes drag, and in the trucks case, lower fuel mileage. Wings do not create smooth air flow over the body and actually cause more drag and that is why super cars with them won't go as fast as those without them.
NASCAR has gone back to a huge 4"x64.5" aluminum blade that's pitched to an almost tailgate like angle of 70-degees. They claim the cars are much more stable at higher speeds and especially in turbulant (or dirty) air.
Most race cars now have some sort of spoiler in addition to a wing and even the wings themselves have a spoiler built into the trailing edge. It's all about pushing down and smooth air flow. There is also a rush to mount some sort of spoiler(s) on the fronts and sides and drag dosen't seem to slow them down.
With all that said, and your thoughts about the "Honda Engineers" and "the delicate balance" it must also hold true for any modification that changes the original design and which will, in effect, also change the running dynamics in a negative way. That means mods to the suspension, larger tires and wheels, massive gains in horsepower, airfoils and ground effects, all effecting in a negative way.
I respectfully couldn't disagree more. Sorry!:smile:
So in retrospect, I don't think there is a guy out there, who is going to take off all of his mods no matter the type of car to abide by the manufacturers recommendations. I'll definitely keep building controversial designs because I love surprising you guys with things from an eccentric mind!
Thanks for the input guys! :smile::biggrin::wink:
