Introducing Affinity Aerodynamics the source for Hardcore NSX Aerodynamic Performance

I know what they are so stop that. I didn't ad that picture of the underbody diffuser to compare to the front diffuser in the original picture I posted. I did it to show that your statement was incorrect.

I also showed a quote stating that the rules in JGTC in 2003 were to make the underbody between the front wheels flat, and not have a horizontal intention in it. Maybe there is something I am missing because what you said isn't what I am reading.

HKS also came out with a diffuser that was studied to create a vortex to speed up the air as traveled under the front of the car if I remember. If they are wrong and that doesn't work then show me how. They said they tested it and it worked. Most probably tested in the typical wind tunnel that they have been using for many years now. It isn't a rolling road but a stationary one so maybe that is where they failed at.

No need to get defensive...

Its hard to tell from my first underbody drawing/photo, but the first panel has proper outer 'diffusers' in it. The second panel apparently is raked (across the entire span) to act as a diffuser or 'wing' -as stated in the comment section, which would make sense as the air can be evacuated in the suspension area between the wheel and the unibody then exit behind the front tires. The third panel has this angle terminate back to the flat bottom plane of the car.

Removing all of the above with a "flat-bottom" as per the rules and quote you stated will indeed reduce downforce substantially. However the first photo you posted seems to replicate the 3rd panel of the JGTC car by expanding then contracting the air (for no reason) and causing no real benefit since the air is not 'diffused' and the panel would not at like a 'wing'.

Is that picture the HKS 'diffuser'? What car is that? GTR? Do you have a different angle of that void? The underside of E92 M3's look identical to that but in the M3, it just ducts air from the oil cooler out of the bottom of the car and is not a downforce generating device.

We tried to chassis mount this wing and discovered the NSX tub is nowhere near strong enough for this task without extensive modification. So, we are reverting to a trunk mounted, swan neck wing, which will be completed soon.

And then, we diverted the above wing to a more fitting vehicle.

Finally, we are considering an NSX specific product catering to those who want more downforce than a Type R wing, but don't want a boy racer wing.

Inquire for interest.

That looks sick!! A bit like Rocket Bunny.

Just stumbled upon this thread and I must say that I am glad someone is doing what I wanted to do with a front splitter. I will ask to see if you have any pictures of the front splitter mounted on you test car? Where are the rear mounting points located and how is this splitter designed to "shear" if an impact occurs?

The Rear wing is very interesting. I might be interested if I could see a few more angles.

I will have some pictures tomorrow, but we have several on affinityaerodynamics.com

"Shear" should occur via the bracket and mounting apparatus. We don't exactly want to test this on a customer's car, so it has not been confirmed. However, based on materials strengths, it should shed itself and/or deflect in the event of a sand trap excursion.

Swan neck rear wing is nearly completed. We stopped by to check out the machining of the trunk plates and the risers. These will be a thing of beauty!!

Cody not sure if you're aware or not but your 02+ is listed on your website as "NA2" and pre 02 is listed as "NA1"

 

[Affinity Aero]

I'll adjust; it was put up in a pinch and that's how we have the fixtures labeled.

Another splitter shipping.

 

[jaffaz32]

Cody, you should make Canards! with options, single and twins etc.

Only person i was aware making Nsx specific canards was Dali and they didn't fit that well.

 

[Affinity Aero]

We are nearing completion of our swan neck options. The wing easily holds two 200lb dudes off either end, without any noticeable trunk deflection. The car is easily pushed/pulled by the wing. The customer is VERY excited about this. Off to machining for the mounts and risers, for weight reduction, final aesthetics, and anodizing.

We can easily build some canards, but need reasonable interest to do so.

Jeremiah Fox, using our aero package, finished Pikes Peak in 4th place in the Time Attack 1 Class with his 330HP 2005 Subaru STI, against machines with more than twice the power, with a 10:47.585.

Now that Shawn's NSX is mechanically ready, we are wrapping up the extensive aero package thats been in the works for months. This package consists of full resin-infused Carbon fiber underbody, side splitter/side skirts. Front splitter with matching canards, rear diffuser, and our Swan neck wing. The overall package should prove to make substantial downforce and reduction in lap times.

Wing testing(solo, no other aero parts) to 150+ mph has shown massive improvements in traction. Shawn's car makes well 700 whp, so it would routinely spin through traction in any gear without the wing. With the wing, it dead hooks above 70mph.

We'll continue coverage of the aero package through to completion.

All parts are currently available for purchase, inquire if interested.

The nsx specific wing looks cool and innovative. But I think it's way more boy racer than a type r style. Why not trying to make a lip spoiler similar to the gurney flap but fitted to a Oem spoiler with Oem led light bar. I'd buy one in a snap and I am quite certain others would as well.

 

[Affinity Aero]

This isnt exactly a "looks" piece. Drum up a quantity of 10 flaps and we'd consider it. We will be offering a wing similar to the BYS aadjistabl unit, but will be larger, and highly functional.
