Italian GP 2010 - Monza

Yes but he's not making much impression in the traps. I think the thing is if you run the f-duct you get a lot more downforce, but then even with the wing ducted, the drag still quite isn't to "teatray-levels"

[marcush.]

no one yet sporting f-duct morphing into teatray design,,so possibly with f-duct banning we will not see this happening.

[djones]

What do you guys mean by they are running different maps?

I know how that will effect power etc but why are they actually doing it?

I dont understand

You're right there. The red bull is a good few kph quicker through the speed traps, as are many others. Apparently, McLaren were saying that a 10kph speed advantage would not be enough to overtake, though. Tough decision to make this, I suppose McLaren will run a tea tray this afternoon and check the performance.

I can't decide whether, if they get similar lap time this afternoon, they will run the f-duct with this concern of being caught on the straights?

EDIT: If Hamilton gets on better without the f-duct than Button, could they split the drivers???

McLaren may have the fastest times in P1, but if the difference in straightline speed to the other teams is 5 km/h or greater, I doubt they can justify running with the f-duct and the high angle of attack in the race. It leaves them vulnerable all the way from Parabolica to Variante Della Roggia, since downforce hardly has any effect in the first chicane.

[marcush.]

I don´t see it that ways ...with downforce galore you will be quite quick at the exits of any corner so your headstart will be considerable.,especially through parabolica.
Also your stability under brakes will be a lot better the question is just :will a teatry car be able to be close enough at corner exit to get a tow early on when mclaren is still making use of their exit speed advantage...but that is doubtful as the teatray does make you traction limited not drag limited on corner exit..

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.

Can't remember where I read it (Scarbs??), however I saw a comment indicating that the overrun for the blown diffuser on the maccas was not fuel fed. i.e. Air Pump rather than exhaust.

They split the front wings in Spa

[nacho]

Renaults are going nowhere on straights, but they were having bit more wing that some but nowhere near as much as the McLarens.

[WhiteBlue]

McLaren have taken the F-duct off Hamilton's car for second practice. They are faster (341 kph) in the speed trap and it looks like they may run this way in the race. Red Bull seem to have the F-duct working well and may keep it for the race. Renault also have the F-duct on the car. Mercedes have taken it off.

[raymondu999]

A Red Bull is fastest. Wow. Wasn't expecting that. I'm personally hoping for a repeat of 2008's results in terms of the winner

[marcush.]

macs did not even try a soft tyre low fuel run .... we have not seen the true picture the Mclaren times ar what i have seen set on prime rubber...

[raymondu999]

I was under the impression McLaren did go on the softs. 5Live's Croft and also Chandhok mentioned that the McLarens were on soft tyres.

[marcush.]

yes they were at the end of the session but on full tanks .did I perhaps miss their low fuel soft run?..could be..
for sure both mclaren set their fastest time on prime tyre
