 Williams Italian GP Friday Practice
Objectives P1
• Aero and mechanical set-up

Objectives P2
• Performance evaluation of the tyres. Evaluation of aero and mechanical set-up
 
Nico Rosberg: Nico Rosberg
 "The most important job today is to find the compromise between top speed and grip and it’s not easy to arrive at the optimum downforce level. We were very slow on the straights this morning, so we looked at this and we have found a good solution. Tyres are just as important and we have completed a good test, from my point of view the direction is pretty clear. The rest of our running time was focused on aerodynamics and we found some good direction, but despite doing some good homework, it is going to be difficult for us here and it won’t be an easy weekend. To repeat the Spa performance of making into the top ten in qualifying will require a helluva lap, but that’s not to say we can’t pull it out of the bag!"

Runs P1: Run 1 new primes (2 laps) install, run 2 new primes (10 laps) baseline, run 3 scrubbed prime (9 laps) mechanical set-up, run 4 scrubbed prime (8 laps) aero level
Runs P2: Run 1 scrubbed primes (6 laps) baseline, run 2 new prime (10 laps) tyre test, run 3 new option (10 laps) tyre test, run 4 new option (6 laps) mechanical test, run 5 scrubbed options (6 laps) aero level,
Kazuki Nakajima: Nakajima
 "Although we are not expecting much here, today didn’t go too badly. Certainly compared to Spa, I think I will be more competitive here, although it is perhaps too early to say how we will go in qualifying. We worked hard today and tried many different technical options, but importantly found some positive direction, so I think the main priority to is maintain this progress tomorrow."

Runs P1: Run 1 new primes (2 laps) install, run 2 scrubbed prime (10 laps) baseline, run 3 scrubbed prime (9 laps) mechanical set-up, run 4 scrubbed prime (7 laps) aero level
Runs P2: Run 1 new prime (7 laps) baseline new tyres, run 2 scrubbed prime (6 laps) aero level, run 3 new option (12 laps) new tyres, run 4 new option (6 laps) mechanical test, run 5 scrubbed option (5 laps) mechanical test
 
Patrick Head, Director of Engineering:
 Patrick Head"We’ve been doing our homework on the tyres today. Both tyres look pretty good and we’ve gathered a lot of data today to go through to optimise our set-up for qualifying tomorrow."

I don't think Williams should be worrying too much about getting into the top ten. Italy has always traditionally favoured to the extremely long one stop strategy- ie lap 30 something. This is because tyre wear rates are usually so low. Maybe Williams should optimise a set up along these lines, and let the others fight it out at the front on their short two stoppers. Then we can do a "Timo" and swoop later on in the race.

. . . we can do a swoop later on in the race.

The chance would be a fine thing.

It's why we call you 'Rusty Cred', CB. And since you always get everything wrong, we all know you are actually Rod Nelson posting in disguise.

I'm just hoping Naka will crash out deliberately here and force a safety car one lap after Nico pits.

It's getting really difficult to take these races seriously, smiling smiley

It is interesting that it is not just Williams that has been caught out by a low downforce package not working when it is put onto the car. We are seeing the true cost of the testing ban. It is a pattern that i expect to see repeated over coming years where teams unexpectedly lose form for certain races because their adaptations do not map from CFD to track in the way that were expected to. There is no substitute for testing.

Williams and proud of it.

Oh dear, Gunk. I sense a bit of frustration boiling up inside you. Please don't take it out on me. as I look to validate my claim I am troubled... however finding a source was easy. Check this one out:

F1 tech data

Race strategy
In theory, a one stop strategy is quickest here, the effect of fuel weight is minimised by the relative absence of
hard braking or acceleration. In practice, the quicker drivers plump for two stop strategies because they don’t
want to compromise their qualifying performance (and, therefore, their grid position). The difference between one
and two stops is also amplified by the high speeds: refuelling typically takes about 28 seconds, including time
spent driving along the pit apron, and you cover a lot more ground during half a minute at Monza, where drivers
average 150mph-plus, than you do elsewhere.

Case closed
