Red Bull RB8 Renault

[bucker]

I heard that RB8 has two fuel reservoirs, one is for race and other for quali, thats how they can achieve better balance with low fuel car. They claim they had more than one litre in the car yesterday, but they couldnt pumped it out because of this system, which apparently is illegal and FIA would put both cars to the back.

Which multiple tank story is this shelly? Got a link?

Weird that the FIA didn't look at marks car, if that was the case? Or is it suggested the system is legal only when used in a failure situation?

I try to resume:
1)Renault-engines are fragile (they say ...) and then to keep them from overheating and breaking RedBull team has asked to use a liquid to cool down the engine.
2) FIA ​​agrees this system as EXCEPTION for the reliability of the engines. But the rules say you CAN NOT 'USE ANY LIQUID TO BALLAST THE CAR, as it would mean better balance.
3)Other teams want to be able to use the same system of RedBull.
4) FIA ​​says these teams that they can not use this system because their engines are not fragile.
The system uses water, oil and the principle of communicating tubes. The system is controlled by the driver in the race according to the instructions of the team.

Cheers elFranz, thanks.

I think u need to re read it again

RB is not under investigation yet in think, those are just rumors and possibilities whats going on with RB, while Ferrari send a question about RB to FIA (http://www.inautonews.com/ferrari-asked ... JZj6m-ULNV). But i think there must be some truth in this, because RB didnt want to pump out the fuel, because clearly they are hiding something.

Conspiracies theory are easy to create. But the simple fact is that the faulty transfer valve was located behind bodywork, and could not be accessed in parc ferme. So FIA had to take whatever fuel was in the depleted area. The system has already been investigated and has been declared fully legal.

Given that the tanks already have subdivisions on them, why would they need a second tank?

nobody know how it's working exactly. but if we suppose they have two tanks, one bigger /race one smaller/qualy two tanks are connected with pump. bigger one was placed on spot where car have better balance when is heavier, and smaller one is on place where car have better balance when is emptier, and pump is connected between them working all the time. during qualy they fuel in smaller tank, but when is race they fuel in bigger one, how race is closing pump pumping fuel from bigger tank to smaller, and car always have good balance.

this is maybe connected on webber problems last weekend in India when from time to time he was very fast, then next slow (maybe alltitude of track have something with this), because of that pump didnt work correctly and webber had problems, who dissapered and appered again.

There are very stringent rules about the fuel tank as this is a major safety factor. I think that many are mislead to believe there is a separate tank while actually it's about the internal small feeder tank inside the main one, fed by the scavenging pumps and whose purpose is to contain a relatively small but constant amount of fuel for the HP pump to feed the engine.
Theoretically there may be a case of full main tank and still not enough drained from the system for a sample.

[wesley123]

I dont understand the fuss about this one either. It is a seperated fuel tank, more like a shield in it, deviding the tank into smaller tanks. This would give less of a shifting weight distribution as there is less fuel moving inside of the tank.

And about there in the tank being enough fuel for a sample; Great that there is, but the FIA requires there to be a sample available, not enough in the tank to require a sample. If there was 100L left in the tank, great that there was, that doesnt change a thing about them not having a sample available. Those are the rules, simple as that

[FrukostScones]

do I see that oil and fuel tank are mixed up?

[aral]

What is interesting tos=day, is the fact that with taller gearing being fitted overnight, Vettels car was so fast. Much faster than Webbers or anyone elses. So will that mean that RBR will look further into their previous short gearing strategy?

[raymondu999]

Other than stint 1 he had better tyres than Webber though - but it certainly was interesting. Maybe the power/torque delicery curves of the Renault block means gearing or DRS top speed actually reduces DRS-limited top speed by only a teensy bit?
