Italian GP 2010 - Monza

[ringo]

W01 has retarded ignition maps as well, though not using it as blatantly. Button was even using it at pit entry.

[Richard]

Presumably McL want to use the retarded ignition as muxch as possible in practice to build up their data set. Risky strategy considering that over use is thought to have contributed to exhaust & valve failure for RB ealier in the season.

[kalinka]

Maybe they're using already used engines, and they are plannig to start with new engines anyway, so it's maybe not bothering them. Just guessing. RBR used a same strategy in Turkey if I remember correctly, and Webber's engine did broke.

Mercedes rear wing a bit small?
at least their trap speeds are quick in FP1...but they seem to be the only ones to not run f-duct in this session...hm

I think McLaren are using that massive rear wing to give Vodafone screen time

None of WB's traditional screenshottery around? :s

[zgred]

I can give You some substitution.

[raymondu999]

awesome It's quite interesting. Was Mark running a different fuel program to Seb? It looks so. And a Red Bull splitting the Maccas. Wow.

And their sector1 times are very good.
Force india looking very strong here. If Luizi is 7th, Sutil could be good for 5th or 4rth fastest.
Redbull is also strong here.

Ham use old FW again?

[ringo]

Not sure, i think the drivers were running different settings, though you can never know until we get some detailed shots.

Anyone has the speed trap? It's a little too soon to be asking, but a screen capture would suffice.

[zgred]

This one is from Live Timing.

Ham use old FW again?

yep, he sure did.

[raymondu999]

Do we know which teams were doing back to backs of teatray wings vs f-ducts, and which drivers used each? And which teams have made up their minds on teatrays/fducts?

Complete speedtrap data from the whole shebang. Bear in mind Buemi had a very good tow all the way from the exit of parabolica from Alonso just in front of him.

[marcush.]

my impression was that merc was the one of the top teams not using f-duct.
I did not look like they were changing back and forth..but oviously i could be wrong.
At the end of the session both mclarens were slower .. fuel related ,or just collecting aero data whereas Vettel tried to beat jensons time.

[horse]

Well, the Merc's f-duct was never that great anyway, so it's perfectly understandable that they took it off.

It's the angle of attack of the McLaren wing which just looks weird at Monza. It confirms my suspicion that they are forced to run a certain wing angle with the f-duct, in order for the system to fit. Probably, as ringo has mentioned previously, this is because the system feeds the flap element.

Good to see Jenson bashing round quickly. BBC made the note that running the f-duct is probably to his advantage here as the extra downforce will provide improved braking stability.
