hmmm I think you might be right Zac but I went on Scarbs website

and it says

(The difference being a winglet has an aerofoil cross-sectional shape and is designed solely to produce downforce, a "flip up" acts to deflect airflow and generally have a consistent thin cross-section.)

I know that flip ups extend from the sidepod and my original question had nothing to do with flip ups so sorry about that. But I tend to think you are right though, I am still new to this game.

You are 100 percent right Zac

in the Turkey Gp, they show Ferrari using the same with there winglets and chimmneys. Thanks for the answer though

Holy crap. Look at the webbing on the Ferrari engine. Probably the ugliest looking cam cover I've ever seen, but I'm sure it's really improved the stiffness of the engine. Seeing this makes me rethink what Ferrari are capable of.

I'm not sure I like the mounting of the upper suspension wishbones. Doesn't look too secure to me. All the load is going into the bolt heads, that just doesn't sit well with me.

The tranny casing looks a little to heavy to me. The Anti-Roll Bar looks a bit bulky too. Also, looks like RB2 has rotary dampers in the rear.
I love to love Senna.

The Ferrari engine as with all 2006 V8 has to meet the minimum weight limit and also a CofG height, the webbing on the heads makes the engine meet those requirements, plus Ferrari as are a Bridgestone team their gearbox is shorter and the rear wishbones feed some of their loads directly into the engine. RedBull use the same engine, but as RedBull are a Michelin team their gearbox is longer, so the wishbones are mounted further back and the casing has to be stronger as there is greater leverage effect due to the greater length. RedBull also use a Renault like support over the top of the engine for stiffness. The bulkiness in the gearbox casing you see is the mating face, the broader this is the greater the friction with the engine interface to prevent the two fretting under torsional load.
RedBull still use linear dampers and torsion bars, in fact they only just switched from coil over springs last year…!

Yes in that second photo the box and engine aren't properly bolted together but it looks like there is overlap on the gearbox mounting surface.

I believe that's the top of the torsion bar, where the linkage is located. It's probably stout enough, although on initial inspection, I too have misgivings.

Nah I see the bit he is talking about. It is right near the corner of the box and is a mounting point in single shear. Maybe it just doesn't take as much load as we think.

The reason why I pointed that out was because none of the other teams gearboxes mounted the upper wishbone that way. I know you're not supposed to load bolt head in shear like that. It's definitely a flawed design, especially with all the power going to the rear. All they had to do was make a bracket for the upper wishbone to mount to, like all the other teams did. It's interesting to think that an F1 designer could overlook something like that on a part so critical to the performance of the car. Oh, well it's only their second year. I can see why they would want to hire great designers like Newey.

I see your point, but I have seen many F1 cars with this arrangement. I presume they model the loads and establish the single shear loading can be withstood by the bolt.

Well, I have no idea what the loads are of course, but I'll will concede that the upper wishbone is less loaded than the lower wishbone.

Also, we've discovered in the R26 thread that this exact mounting system was changed from last years car to a U-bracket type on the R26, although the R25 was held by three bolts instead of the two on the RB2.
