Fair enough. I am still a sceptic though as I think if it was such an advantage it would have been more widely used in motorsport.

We have done further research today on the use of active aero on various supercars, and have added more info to our "The History Of Active Aero" article here ...

http://www.tunersgroup.com/active_aero_history.html

That new section on that page reads ...

--------

There are a number of supercars that run active aero, some of them at the higher end of the price range and not frequently seen, so many people don't know that they run active aero ...

Bugatti Veyron

The Bugatti Veyron's active rear wing changes height and angle of attack. Adding height to the wing moves it into cleaner air (making it more effective), and adding angle increases the downforce coefficient of the airfoil (blade).

Click here to view a video of the Veyron's rear wing in operation ...

McLaren F1 Roadcar

The McLaren F1 roadcar also changes the angle of attack of it's rear wing.

http://en.wikipedia.org/wiki/McLaren_F1 reads ...

There is a small rear spoiler on the tail of the vehicle, which is dynamic, the device will adjust dynamically and automatically attempt to balance the center of gravity of the car under braking – which will be shifted forward when the brakes are applied.

Porsche Panamera

large1396.jpg

The Porsche Panamera also uses active aero.

http://www.autoblog.com/2009/06/25/first-d...78-years-in-th/ reads ...

Active aerodynamics are standard equipment on all variants of the Panamera, but they alter slightly based on trim level.

The Panarama S and 4S feature a one-piece rear spoiler that is retracted and flush with the bodywork until the sedan reaches 56 mph, at which point it moves into an angle of -3 degrees.

At 100 mph, the wing angle lifts to +5 degrees to increase downforce. At 127 mph the spoiler moves to its maximum deflection of +14 degrees.

The spoiler on the Turbo model is fitted with two additional flaps that extend to increase surface area. It too deploys to -3 degrees at 56 mph, but then locks at +10 degrees at 127 mph and up.

Ferrari 458 Italia

large1397.jpg

The Ferrari 458 Italia also uses active aero.

http://news.teamxbox.com/xbox/21027/Forza-...-Screens-Video/ reads ...

The 458 Italia is a combination of banned F1 active-aero technology and the voluptuous vision of the Pininfarina design house. The Ferrari features ‘aerolastic’ spoilers in front that shape shift as the car accelerates altering the flow of air into the radiator and decreasing drag.

Honda

Honda is also working on active aero.

http://www.autocar.co.uk/News/NewsArticle/...oncepts/244309/ reads ...

Honda is working on active aerodynamics for its next generation of cars, and will introduce the technology within five years.

Nobuki Ebisawa, Honda's R and D managing director, said active aero would be introduced to get away from the high, cut off tail that characterises cars such as the Insight and forthcoming CR-Z.

Interesting stuff. Do you know of anyone running these wings (active or static) in any aussie CAMS sanctioned event? I have asked our eligilibility officer to look into it, for the 2010 season.

Hi Duncan,

As far as I know no cars in Australia are running them yet, but as detailed earlier in this thread they are being used on a bunch of cars in the US.

There are also a number of cars running them in Asia already ...

We will be speaking to CAMS later this week to help familiarise CAMS and their scrutineers with the Aeromotions wings.

Sounds like some pretty impressed customers there and definatly some positive feed back. Are all their wings a generic design or are they model specific as i would be interested in pricing on a static wing for my R33GTR if they are available as i have been looking into options for my track car and have mainly been looking at some of the japanese product available. I would also like to know what the actual weight of the wings are if possible.

ok, will be interesting to see how you go. You may want to review cams sports sedans rules before talking to them. I noticed in the marketing stuff for aeromotions you can run the wing in a fixed position to satisfy racing regs, say for a given meeting, please ask them if they would allow that (if you get an initial negative response) i will be interested to know. my email address is duncan_forrest at optushome.com.au please emai me your pricing and availability for the fixed and dynamic wing. (non-split versions). FWIW i think CAMS regs will exclude spilt designs entirely.

Hi Dazmo,

For all models of the Aeromotions wings, a universal version is available as well as the model specific versions.

So currently the available versions of each wing are:

- Nissan Skyline R35 GT-R

- BMW 3 series E36

- BMW 3 series E46

- Corvette C5

- Honda S2000

- Mitsubishi Evolution 8

- Mitsubishi Evolution 9

- Universal version

I would also like to know what the actual weight of the wings are if possible.

The single element R2 Static weighs 5.7 kg (12.5 lb)

The single element R2 Dynamic Wing weighs 7.9 kg (17.5 lb)

The split element S2 Dynamic Wing weighs just 4.7 kg (11.0 lb)

The weight savings on the S2 Dynamic are achieved by using teardrop shaped uprights from an airplane, Formula 1 grade dry pre-preg carbon fiber, and titanium internals.

We have put together a comparison matrix for each of the wings here, showing specs, weight comparisons etc for all the Aeromotions wings ...

http://www.tunersgroup.com/Products/aeromotions_matrix.html

The pages with full product info about each wing are also now online ...

The single element R2 Static is here ... http://www.tunersgroup.com/Products/aeromo..._r2_static.html

The single element R2 Dynamic Wing is here ... http://www.tunersgroup.com/Products/aeromotions_r2.html

The split element S2 Dynamic Wing is here ... http://www.tunersgroup.com/Products/aeromotions_s2.html

i would be interested in pricing on a static wing for my R33GTR

Hi Dazmo,

We have been finalising pricing this week.

Pricing for our US customers is here ...

http://www.tunersgroup.com/Products/aeromo...pricing_US.html

AUSTRALIAN PRICING

As I wrote earlier in this thread, "As always, our Australian pricing will be as close as possible to prices in the US where Aeromotions is based."

Australian prices ex shipping will be roughly equivalent to the US prices above plus import duty and GST. The landed price will vary slightly depending on which part of Australia a wing is being delivered to.

We can arrange customs clearance etc so that customers do not need to deal with the time consuming process of doing a formal customs entry, which also helps our customers avoid the lengthy delays that can happen in customs clearance.

Our customs broker is currently checking on the exact duty rates etc so that we can have exact Australian prices. Similarly our shipping companies are working out the best options for shipping. They should all be finalised this week.

Given that the S2 Static Wing is priced for our US customers at US$1699 and this post posted by a driver with an S2 Static Wing on an R35 GT-R http://www.nagtroc.org/forums/index.php?sh...st&p=472311 reads ...

My GT-R was transformed with the wing. I dropped 1.5 seconds on a 1:20 course at Roebling Road, and the difference in feel is immediately noticable ... I am running the static wing for now.

... that's very good value for a potential drop in lap time of that magnitude.

- The Tuners Group

I am keen for a wing, please send me a price delivered to postcode 2035 duncan_forrest at optushome.com.au

i need two quotes, one for a fixed version and the other the dynamic (i dont think i can run the split version). You should get lots of exposure next year :( we plan on lots of video work showing all components on the car! cheers.

Reminds me of the early model GTO's
, but more advanced off coarse

Cool video GTOMR !

I also just found an article on TMR about the Aeromotions Dynamic Wings with some additional info about how they were developed ...

I LOL'd when I saw this part of the article ...

Despite all the hard parkers you see cruising your local entertainment district on a Friday night, a rear wing is actually useful for more than just a place to rest your cup of Coke if you’re driving your modified car at the track, not just to McDonald’s. This wing appears to be the next step in aerodynamics for motorsport enthusiasts.

Hi LSX-438,

The data from the Thunderhill test mentioned above produced the following lap times (the wing used in this test was the split wing, running in 3 different configurations):

- Without Aeromotions Wing: 2 minutes 10.1 seconds

- With Aeromotions Static Wing: 2 minutes 9.2 seconds

- With Aeromotions Dynamic Wing : 2 Minutes 8.4 seconds

- With Aeromotions Dynamic Wing With Centre Fence): 2 minutes 7.7 seconds.

So lap times with the Aeromotions Dynamic Wing running in dynamic mode were 0.8 seconds a lap faster than the wing running in Static mode.

And lap times with the Aeromotions Dynamic Wing With Centre Fence were 0.7 seconds a lap faster than the wing running in in dynamic mode with no centrefence.

large1304.jpg

What I found really interesting there is that the simple addition of the centre fence cut 0.7 seconds off the lap time compared to running the split wing in dynamic mode with no centrefence. The centre fence is the vertical plate that runs between the centre of the two split elements - see photo above.

The reason for that is that a centre fence isolates the airflow over each half of the split wing, and can have a huge effect on increasing aero efficiency and cleaning up aero flow. That then lets each half of the split wing to work more efficiently than without the centre fence.

That concept is the same reason that the Boeing 747-400 and Airbus A380 run upturned wingtips on the ends of their wings. This effect was also mentioned in the Richard Hammond show on SBS a few weeks back about the development of the A380.

800px-Wingletdetail.jpg

Above is a photo of the wing tips from an Airbus A380.

There is a diagram here of the effect on airflow ...

737winglets.jpg

There is an article on Wikipedia about that effect here ... http://en.wikipedia.org/wiki/Wingtip_device

It reads ...

Quite a few other planes run upturned wingtips for the same reason ...

NASA-2000Starship.jpg

NASA_Fig080.jpg

I'll check with Aeromotions to see if they have data available about the difference in performance between the single element Dynamic Wing and the split element Dynamic Wing. Given that the simple addition of a centrefence on the split wing cut 0.7 seconds from the lap time though, I wouldn't be at all surprised to see a very significant difference in lap times between the split element wing and single element wing.

And the airbus stole it from eagles. So in turn we owe faster lap times to a bird and generations of evolution

Top of the line Aeromotions S2 split wing, awesome stuff. about 8k aus. Some spend almost that on a carbon fibre lip or rear spoiler with no added aerodynamic benefit so probably not insane price for something with this level of functionality. I suspect a few track guys here would be interested in this, it seems to provide noticeable results

Were can i get myself a aeromotions S2 split wing for my R35?

    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
