Why would it be the last thing? An air dam is very useful. You can practically do what you want with the high pressure "air source" of an air dam. You can use it for downforce like a big ole' gurney flap, You can use it for cooling, Air deflection. The relative velocity of the air in the damn can be zero if it is closed off - of slightly higher if you bleed it off somewhere.Adrian Newby wrote:The air intake on the nose is far too large for its primary purpose to be "driver cooling".
And an "air dam" is the last thing he would want in that already narrowed area between the front tires (an air dam, and the air being redirected by it, wouldn't just go upward, but also outward).
I believe Adrian Newey is attempting to have the exact the opposite effect of an air dam. He is trying to get rid of any build up of air caused by this newly necessary hump in the nose by routing air through the bulkhead, past the driver, and out the cockpit opening.
There's definitely something like that around the 53 second mark, for a sustained period, but otherwise it just sounds like a race car on overrun, with throttle blipping.Hail22 wrote:Is it me or do i hear an EBD coming from the RB8?

There is something to stop the wheel from shifting, the 'lower wishbone' that branches of the main. I am in no way an expert but the only downside I could see is that you would not be able to have control over camber as the suspension compresses, it would be a constant change in camber. With two separate wishbones you can control the camber rate as the suspension compresses. excuse the brutal diagram but this is how:AbbaleRacing77 wrote:A single spar lower A arm would be a dumb solution and impossible if using ball joints. There would be nothing stopping the wheel from shifting and changing castor angles... Not to mention that triangulating a suspension component would allow you to make the A arm thinner and block less air heading to the back of the car.
Judging from that youtube I dont think what were hearing is EBD. Their engine noise is definately different than the Sauber(Ferrari) which sounds truely on song in comparison.IMOHail22 wrote:Is it me or do i hear an EBD coming from the RB8? I hear slight blurting (blowing sounds) eminating from that car...even more interesting is that the Lotus tone is slightly different.

I don't think that is EBD either. That sounds like engine braking at the 53 second mark to me.Mr Alcatraz wrote:Judging from that youtube I dont think what were hearing is EBD.

that's what air dams do. and gurneys are similar. you impede the flow to gain pressure or loose pressure in a particular place.Adrian Newby wrote:Air dams can be useful, in the right places, but this is not one of them.n smikle wrote:Why would it be the last thing?

Designers try "waist" the area between the front tires and under the nose (remember, 3D) to get as much high-energy air to the undertray as they can, much like they waist the rear bodywork to get air to the rear wings, top of the diffuser, etc. An air dam in this area (whether top, sides or bottom) would impede the flow they want most.
Are driveshaft, trackside arm and rear leg of the lower rear wishbone all incorporated into one fairing?imightbewrong wrote:Okay, from the pictures above I'm pretty sure it is two wishbones, but the lower one is small and the back leg of the LW is shrouded with a cover along with the drive shaft.
I know my drawing is a mess but pink is Upper Wishbone, green is lower, and orange is the drive shaft. Hope you can understand my mess.

From what we sse in this picture the copper and blue strips seem to be something different from temperature sensing strips, which are fitted on top of the beam wing.zgred wrote:
Chalk another vote up for 'no exhaust blowing'. Sounds like regular down-shifts with a throttle blip and overrun to me too.Hail22 wrote:Is it me or do i hear an EBD coming from the RB8?

That looks more like regular body roll than flex to me, it looks like the shot was taken in the right-left-right so the weight would be transferring that way. The wing looks pretty straight tip-to-tip, without the 'droop' at either edge typical of last year's flexi-wing.Hail22 wrote:One thing is certain the flexible wing is back as you can tell from the angle its bending on the left.
I wish they banned that...
