Red Bull RB8 Renault

Would there be any benefit to channeling a significant amount of air into the driver compartment?

Yes I believe there is.

MW indicated on ONE HD interview with Daryl Beatie that they have a problem with balance on both cars. Balance is fine going into a corner, and during, though not coming out of the corner. MW and SB lacking complete confidence on corner exit.
For me this adds weight to the earlier discussion around RBR having to ditch the blown exhaust loop hole.

MW also talked of the need to gap the Mercedes powered car before the DRS zones. Obviously concerned at the lack of straight line speed.

I"m happy to be proven wrong but that actually sounds more like the exhaust isn't doing what they expect. On corner exit the throttle is being applied so there shouldn't be any issues caused by off throttle blowing.

My view is that it is more likely to be that the exhaust that they threw on for the last two days of testing isn't working exactly how they want. So off throttle the car is working okay and is balanced, but depending on how much throttle they apply the gases are sometimes going where they should but sometimes are just drifting slightly away from where they want them to go.

I think because to all the tubes, vents and all the other body work they have incorporated into the rear of the car, rather than letting the air/exhaust gas find its own path, they are playing around with it to much. Sometimes the simplest form is the best. I wouldn't be surprised if on corner exit the first impulse of exhaust is hitting all those channel edges and acting more like a shock wave. This is then causing separation and loss of rear DF untill the air has time to reattach itself and flow throwing the channels. It could ba a harmonics problem where the diameter of all the channels over the lower floor have air passing over the exit faster than that entering the front and causing the air to be sucked out (causing lift and drag). That's a little hard to explain without a diagram so will get my pencil sharpened!

Are you trying to show something specifically of the RB8?

[Blackout]

It's just a photo that shows the difference philosophies between the too cars... a photo witch is beautiful too

Mostly it's a good comparison of the sidepods/rear end and how tight it all is.

[Guisson]

Yep RB Sidepods looks narrower that Macca

I'm not saying you were wrong to do it - just asking if you were just showing a beautiful photo from the top - or if you were trying to point out something in specific

Looks like McLaren's side pod does not really start to tapper until it reaches the exhaust outlet.

Aero significance of a flatter outside surface on the sidepod? Helps with the aiming of the exhaust?

It does taper on the vertical plane though - it drops down there.

Remember – the taper on the McLaren is under the exhaust bulge, so it's very hard to see from above.

[raymondu999]

Technically isn't that an undercut though? If we want to argue on such semantics; that is.

I guess you could realistically argue that – I'd suggest though that really it's a taper, with an aero device attached to the top – but it is a very blurred line.

Either way both cars actually taper by a similar amount, McLaren have just chosen to put more bulk further forward whereas Red Bull have more bodywork further back.
