Red Bull RB6

"But to tell you now Kimi will be racing for us in 2011 is not serious. If Webber provides top performances this year we will not reward him by giving his cockpit to Raikkonen."

He says what happens if Webber has a good year .. he provides lots of room by ommision if Webber has a bad year (and BTW I think webber will do great .. but if he doesn't ..)

That also says a lot about Webber's outlook. He's already admitted being in a race-winning car is what has kept him from retiring.
So if it is he that personally prevents the potential for race wins, he'll walk away of his own accord.

Exactly!

We've seen what he can do with a badly broken leg and a broken shoulder in a good car so imagine what he will do this year in the Rb6 now that he is healed!

I'm new here but isn't this a technical forum and a car thread, not a fanboy driver discussion?

[D'Leh]

Yes slideways, usually those kind of posts don't interfere here. But during winter, when there are few pics and nobody really knows who is fast and who has been showing off it can happen. It will be better soon.

So you expect a revolutionary change for Bahrain?

And out of interest... why aren't you at your post?

revolutionary change? no but i certainly expect updates for the first races that amount to more than 'minor tweaks.' the exhaust being one

who can answer for myurr why tk421 wasn't at his post? i'm sure someone else here besides myself knows!

As I like to say; "This is not Buckingham palace!" F1 is an extreme sport! If you are a fan of a driver nothing wrong with letting people know.

I don't know about you but I like fan-boy comments and trash talking. I try not to do it on this website too much because some people are not used to trash talking (they can't take it) and the fan-boy comments can annoy those not concerned, especially when they don't have a favourite driver (or their favourite driver sucks!). So sometimes you have to restrain yourself and try to keep it technical.

This is why I can't wait till the race threads open up..hehe.. You can sorta do more trash talking while the race is on.. but those threads are still "technical-ish" analysing the race and whatnot.

well said. as nsmikle coined 'the boss' (i believe) for hambone, i'm trying to coin 'the haus' for vettel

[TRICKLE69]

Is it possible that the exhausts are directly feeding one of the levels of the diffuser now that they are horizontal with the floor?

indeed!

what does "the haus" translate to in English?

Thankfully Mark being an aussie makes his nick name easy .... It's Webbo! (with an aussie accent of course)

No, diffusers feed from underneath the floor, the exhaust exits above it.

I have another "is it possible question". Will there be enough "negative pressure" at that location to actually make it work like an exhaust-side turbo to increase the thermodynamic efficiency and basically increase the engine performance at that location? Some of the drawings that I saw kind of suggested that the pressure over there could be as low as anywhere else in the bodywork. 1 HP is 1 HP, especially if you're running a Renault engine...

Last i checked, this thread is part of the General Chat forum..
We're not all engineers here, & contrary to recent belief the driver is still a fundamental part of a a race-winning car.


And what's with this new craze of throwing around 'fanboy' claims everytime a driver is mentioned?

Surely if someone blindly claims a driver/team/organsation sits next to god with no faults, such a claim of fanboy could be made.. but over discussion about a team's comment on a driver's seat? Surely that's getting a little uptight..

quite possible; some ingenious Newey way

It's not anything like a turbo for sure but If you mean as in some type of exhaust pulse effect, for naturally aspirated engines that is a complex topic. I don't know anything about acoustics, there might be others than can answer that. But in terms of having a lower pressure outside the exhaust. A lower pressure might increase the thermodynamic efficiency somewhat because it will be easier for the gas to be pumped out of the exhaust. The exhaust leaves the chamber easier and faster. I guess you can get more fresh air into the engine during the time at which the exhaust valve is closing and the intake valve is about to open (valve overlap) so there might be a better combustion efficiency too. But with these complex motions and phenomenons that are occurring in the fluid it is hard to say you gain more power, you can even cause the engine to loose power too.

If it was all to have the lowest pressure, all the teams would put 5 inch diffuser cones on the exhaust pipes. But they don't so maybe you can say that there is an optimal pressure in the exhaust collector that they must have; not high and not too low.

Overall I think the effect on the engine from putting the pipes down near the floor is negligible. Because the flow through those F1 exhaust pipes are so unrestricted and the pulses are so rapid and violent that the slight drop (or rise) in pressure by merely pointing the exhaust in a different direction is minimal.

If it the engine was turbo charged though, you want that pressure as low as possible! That is because turbines operate on pressure and temperature difference. But these cars are naturally aspirated so yes, I think it just moving the pipes down is negligible. If you point the pipe FORWARD into the breeze, now that is not negligible! That is whole different magnitude of pressure there.

[PlatinumZealot]

If the exhaust pipe was actual exiting INSIDE the throat of the diffuser that is different story. Now that is "feeding."

To point the exhaust so that the gas grazes over the diffuser as it flies past is more helping the air to escape the diffuser easier.

So when I hear people say feeding, I think about air that is going to the throat of the diffuser, that is inside the diffuser. Remember the diffuser's entry is always from under the car. So we need to be consistent. The only exceptions is when you have tricks like putting slots in the roof of the diffuser and this is still after the throat so it is still not feeding, just "helping" or "blowing" (yes that word) the air that that is already inside the diffuser to get out.

Hey all - first post. Check the very top left of this image. Did anyone read Scarbs' article about McLaren using cameras to record tyre temps? Anyhow, my bet is the small pod you can see is RBR's version for measuring temperature distribution on the rears. Neat.
