ooooooooo i cant wait to see this thing in action again.. with the new front aero, and wheels that actually fill out the guards.. it looks like a proper jap time attacker.. well done fellas.

Acts as an air brake or spoiler into the corner but when you need some angle of attack for downforce in the corner especially a high speed corner it starts to flatten out and the car loses down force , hence the skittish rear end , , though of course the big horse power is to blame as well.

Hi Kimbod,

As mentioned by others in this thread, the car had an issue with the 4WD system which was contributing to the rear wheelspin on the day the video was shot.

We were at the test with Mark's team - we are Aeromotions' exclusive Australian and NZ distributors.

The change of wing angle from the high downforce braking setting to the high speed cornering position is intentional and the wing angle is adjustable.

The Aeromotions wing has it's own computer that controls the wing, and has inputs from the speed sensor and an accelerometer that detects g-force etc.

There are 4 adjustable wing angle settings on the Aeromotions R2.TWO wing:

1. Straightline setting

2. Braking setting

3. Low speed cornering setting

4. High speed cornering setting

Each of those 4 settings can be set to a different angle, so the aero can be dialled in for each setting with different wing angles for straightline, braking, low speed cornering and high speed cornering.

If you have a look at the video here ... http://www.tunersgroup.com/Videos/berry_ec_test_mar3.html

... the part shown at 3 mins 2 seconds into the video is of the braking area at the end of the straight as the car brakes for turn one, so what you are seeing in the early part of that shot is the wing in the high downforce braking angle setting.

In the later part of that shot, as Mark then gets off the brakes, the wing flattens out again, but the angle it flattens to (the high speed cornering angle) is also completely tunable and adjustable.

There is another good shot of the wing popping up into the high downforce braking position as the car passes under the bridge at 3 min 57 s.

You can see sequences of the wing flattening into a low drag straightline setting as it comes out of corners and onto straight sections at 4 min 3 s and 4 min 30 s in the video.

Many years ago in the late 60 / 70 when movable aero devices were still allowed in F1 ferrari did the same thing. The wing was operated by engine oil pressure . going fast , high oil pressure, flat wing, into corners revs drop angle of attack increases giving more downforce but since you are moving on the throttle all the time balancing the car the down force changing constantly in the corner making the car unbalanced.

Yes active aero has been used in a number of classes of racing over the years.

Unlike systems that change wing angle with throttle position, with the computer control of the Aeromotions Dynamic Wing the angle of the wing does not change constantly in the corner as the throttle angle changes.

As seen in the photo above, there are two electronic linear actuators that move the wing into different angles.

hope you get it to work cause it looks great

The video was the first test day with the new Aeromotions Dynamic Wing on the car, and we have 9 weeks until World Time Attack, so the aero will be well and truly dialled in by then.

Two weeks ago, Australian racer Duncan Forrest smashed the Class 4D lap record at Eastern Creek in his R35 GT-R with an Aeromotions Dynamic Wing by 1.3 seconds. The old record had stood since 2005. See ...

The Aeromotions Dynamic Wings are a known quantity and are proven to cut lap times. They are used on a number of the world's top time attack cars including the Crawford Subaru WRX STi, AMS/NOS Energy Drink EVO X, and Cannonball R35 GT-R. More info about teams using the Aeromotions Dynamic Wings and the lap time improvements they have achieved can be found here ...

So there is no question that we will get the Aeromotions Dynamic Wing dialled in and working very well on Mark Berry's R34 for World Time Attack Challenge - getting things dialled in is exactly what test days are for.

just something i put together in a lunch break. Was too good not to go and film!

It's an awesome video Andrew - congratulations to you and your crew at Motive DVD on a job well done and some awesome footage that really captures just how fast these top level time attack cars are. :down:

Look at the vid and you can clearly see the 4wd system not working. When they get that problem sorted, then watch it haul ass. It will be a totally different car.

Spot on Lippo.

Awesome awesome car, can't wait to hear how it goes when its all dialled in.

If it does it will give them an overdue wake up call !!

What wake up call is this, and why do they deserve it? They have been doing an awesome job of setting near impossibly high bars time attack , definitely not being cocky about it at all as is evidenced by heading to Australia to take part in this event - they are obviously looking for the sport. They are well ahead of the game, though racing away from their home turf will no doubt narrow the gap a bit.

Good luck!

    • Nah, they'll do it without a receipt, tell em roughly when it was, that it was cash, youll likely only get store credit, but that gets you some dollars towards the newer better shovel, or other item you need/want later.   Still take it back and have a crack at returning it.
    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
