Abandoned (or poorly stored) NSX in Mississauga

Over the Xmas break the family stayed at the Stage West hotel in Mississauga. On the second night I decided to park in the indoors lot and while looking for a spot what do I see huddled in a lonesome corner but this Brooklands Green NA2.

It had 2 flat tires, a thick coating of dust, water drops were all over the hood and roof from the melting saltwater seeping through a crack in the ceiling overhead which was under the top uncovered level of the parking lot. Someone had written "I AM A NICE CAR, CLEAN ME OR GO AWAY!". I managed to scrape away some of the encrusted dust on the passenger window to see it was an NA2 (6 spd), had 3 defi gauges on the centre dash, an aftermarket steering hub with the steering wheel removed, and a Bride Gias Low Max seat in the drivers side. There is a red authentic Honda badge on the front, appears to be lowered but otherwise stock.

I am guessing it must belong to someone connected to the hotel, otherwise why would it b parked there for so long. I also assume the owner has not seen it in a while or s/he would have moved it to a less exposed location or would have at least thrown a cover on it.

I'm hoping someone might recognize the car and help the owner retrieve it. Heck, I might even consider buying it so it ca have a better home!

Wheels (again)

Just when I thought I was pretty well done with the topic of wheels, up comes Chris at Science of Speed with this post:

Ray's Engineering Volk Racing TE37 forged monoblock wheels are the standard for light and strong wheels for both racing and street use. Several years ago, Ray's discontinued the 18x10.5+45 wheel, which was a popular wheel for the NSX because it offered the best width and offset for popular larger tires - but also because it offered a deep concave face not seen on many wheels for the NSX. Despite it being popular for the NSX, it was discontinued because it was one of the only cars using this size and Ray's could not justify producing the size any longer.

ScienceofSpeed has collaborated with Rays Engineering to produce a 17x8.5 +40 and 18x10.5 +45 Volk Racing TE37 wheel ideal for street or competition use. Produced with exclusive forge tooling to produce this size and offset, ScienceofSpeed is able to bring back the popular concaved rear wheel on the NSX previously discontinued by Rays.

The ScienceofSpeed Volk Racing TE37 is being offered in two finishes never before offered on these wheels. Genesis Gunmetal (a bright satin gunmetal finish) and Satin Black / Red Ring.

In our experience, this is one of the best sized wheels for customers wanting to use larger tires on the NSX. The rear supports up to a 305, but most customers will find 235 and 285 or 295 is the ideal split.

A very limit number of sets (five only) are being produced for ScienceofSpeed. The estimated delivery date is the end of March. To place an order, we are taking small deposits. If you are interested, please call or e-mail for more information.

The price for the set is $2895.00 - there is no difference in price between the two colors.

*** Pre-orders: a $100.00 discount is being offered for pre-orders placed before until Jan 1 2010. ***

I hav always loved the TE37's. It's a classic wheel for Japanese cars. It's almost the national wheel of Japan :) I had a set of bronze TE's on my Nsx and sadly had to let them go when it became obvious that they weren't going to clear my new brakes. Now I have a chance to get them back and in a very sick offset that will bow inwards in the rear. I already have a standing offer on my CE28's, so I can stand to break even, or come very close to it (not counting tires). My Bridgestone So-3's on my Tecnomags will go on the TE's for now and in the fall I ca order a new set of tires when MidnightRuns do their annual group buy. What to do...

It was bound to happen...the BIG ASS WING

As I get more and more hooked on tracking my car, my mind is drawn to the idea of a big ass GT wing (or as my friends call them, "F U wings").

Right now I am sporting a NSX-R style wing made by Jetz, which is light and I like the fact it retains the led third light. I also like the idea that it was designed with wind tunnel input (or at least the oem one was). The worse part is the fact it bisects my rear vision. I have the DF NSXR flat under tray pieces (nose and battery tray, gas tank etc) terminating in a Taitec open diffuser. I try to have a completely flat underbody leading to the diffuser and am very happy with stability at speed. I have learned that the R wing only functions to reduce lift (along with the flat undertray), but does not generate usable downforce.

Personally I am not very crazy about the looks of the aerofoil on the back of a street car. It's big, obnoxious, and the fact that every FWD ricermobile seem to have one is a big turn off. However, I hope that my NSX being more and more a devoted track car will justify that. I have found out that the design of the wing itself makes a big difference in whether it works noticeable or not (duh). The Taitec is essentially useless. Big, heavy and rated as an "anchor" by one former owner.
TAITEC GT-500 (form over function):

Billy Johnson of FXMD (famous for his green and black time attack winner) says "The trailing edge of Taitec GT500 is soo steep (pretty much vertical -not a true airfoil) that the wing will stall out at very low speeds resulting in a ton of drag and not much downward force".

In the functional wings category we have the APR:

My only beef with this is the fact it desn't look very pretty just mounted on the trunklid like that. I'd like to fill in and blend the base with the bodywork.

My second choice is the Sorcery:

Third choice is the Gruppe M, which is discontinued.

John@Microsoft says: "Obviously a big ass wing, albeit it the Taitec or Doug H's home-made mongo aluminum home depot one will produce effective downforce on a road course. Like putting your hand out the window... that's probably the easy part.

However, every wing design is a balance. What separates a highly optimized computer modeled tunnel tested design from a poor garage tuner design is being maximally effective while minimizing drag so you get the best of both. Further, having it co-exist well with the rest of the vehicle's aerodynamic characteristics and perhaps most sought prove well in the field for the intended course speeds/application/driver.

All wings are not created equal. Their are low speed high down-force configurations, multi-element high speed airfoils, multi-surface designs such as a sprint car wing, etc... Even the little end plates and wing mounts design play their part in the effectiveness of the system as a whole.

An interesting trivial point, but from what little I have read historically, they banned mounting wings directly to the lower suspension members, fan cars, and other active aero devices simply because they were so ridiculously effective.. so now all series specify the mount must be to the chassis and a great part of pro R&D goes into simple wing design. Per an issue of Race Car Engineering, in Formula 1, even the composite material layering is optimized via FEA to allow just the perfect amount of flexibility across the span so as to reduce the designs effectiveness at high triple digit straight line speeds as that is 'free' per their rules".

The one I decided on is the one currently on Scorp965's red Turbo NSX. He's selling his car, parting it out and moving on to an Aston Martin.
It is the Voltex Type IV with the molded trunk base piece, Gurney Flap (which creates a small vortex on the trailing edge that generates more downforce) and end plates.
This is the actual wing:

Peter Lau has the same wing but with shorter stands and wants the taller ones I'm getting. I'll have to see once it is installed which ones I prefer. My wife hates the wing but says it's my call. Thanks babe!
