Red Bull RB8 Renault

We don't seem to have a picture of the current RB8 rear body work?

It's the same as the older one - just that the tunnel is now closed off. So basically they have an almost-replica of the Sauber rear end.

Here's a pic for you

New swivel jack for Red Bull? I think they were still using a "traditional" front jack in previous races?

This unit has hoses, is it hydraulic or pneumatic?

Yeah I'm pretty much with Owen on this one. I think the flows; exhaust, lateral flow & flow over sidepods were causing problems in the way Newey had them coming together. The new way is more straight forward and probably easier to manage.

Or maybe they had the wrong aero map for these tires, or spring rate, sway bar, camber curve, etc....

This is the best high-res pic I could find.

Its a system based on a manual pallet truck that is seen moving stock arround in a warehouse. It uses hydraulic oil. However the ones that Mercedes, Ferrari, Red Bull and the rest are using are all on steroids. Usually 1 pumpgives a 8mm to 12mm lift, theese ones in F1 look as if they give ten times that, posibly 80mm to 120mm.

Something like this is what they are using:



The rear jack is the same, however i surprised they arnt thinking about trying one of the front systems on the rear as well, if they found it gave a tenth in a pit stop they would use it.

I think Red Bull will shift to a lights system soon as well, as most teams are starting to make them work propperly now.

It's not nearly as critical at the rear because getting out of the way of the car is not an issue.

I'm not so sure about that. They have the exhaust further forward now.

Edit: just got it wrong before

My vote would be for the airflow into the tunnel adversely affecting the exhaust flow. Remember they did some flow vis in China specifically in that region and it looked like there was a stagnant region of air around the rearmost edge of the tunnel entrance.

Brings a smile to my face remembering all those predicting the season was over when they saw that tunnel

We should be careful of predicting a renaissance though as the conditions are sufficiently different in Bahrain for it to be a one off. Red Bull were predicted to go well here before the weekend began.

I'm not so sure about that. They have the exhaust further rearward now.

Maybe they had it further forward to create room for the tunnel?

Best shot I could get: (so far, anyways)

The exhaust exit actually looks like it is in the same location, they've just filled in the tunnel.

For comparison the old exhaust.

Looking very Sauber if I may say so myself.
