Video Of Mark Berry's R34 Testing At Eastern Creek Raceway

So Whos Goin?

[JET200]

they were 'TESTING" the rear wing.

it does need some fine tuning as yes, it was going flat while accelerating out of the corner. Needs to stay angled up for longer

off lips!!

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.

[CARSICK]

Thanks Andrew for the lead > 22nd May already penicilled into my calendar!

Hope the adjustments are all ironed out on the R34

thats so cool, i love the sound of it.

hows the side windows lifting out as he is flooring it.

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.

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!
