Every message, in the order it happened
Engineer: So of course you can do a bite point find on the way to the pit exit, session starts
Engineer: suddenly something failed, suddenly, I don't know
Engineer: Carlos, standby. Let's try a power cycle. Try a power cycle.
Engineer: Cover that Nico, so stopping before the marks so you can lay rubber through the box, but before that we're going to do a nose change
Daniel RICCIARDO: Yeah, all okay. Steering feels light, just first feeling with steering, but all okay.
Engineer: And a repeat of the Aero P4 5th gear cruise before turn 15 please.
Engineer: Which is
Lewis HAMILTON: the wind direction?
Engineer: So it's showing headwind into one but very low in strength so practically no wind.
Engineer: OK, thank you for that, and we're boxing this lap, so practice your stop position please. OK.
Engineer: So cool down lap, and let me know if you want to flap adjust.
Engineer: OK, this is all clear around, so that's P1 to Valtteri, P2, he's just a tenth behind in terms of sectors, down two tenths, sector 1, up 700, sector 2 and up two and a bit tenths, sector 3. Losses to Valtteri, braking and minimum speed turn 1, 2 and then minimum speed turn 8.
Lewis HAMILTON: What's
Engineer: the
Lewis HAMILTON: last set?
Engineer: Minimum speed turn 8.
Engineer: Okay,
Daniil KVYAT: all okay, just the track seems very dusty. When the boat just passed by, there was a lot of dust out of his car.
Engineer: Lewis just finished his lap, he's at 30.9 So he found quite a bit of time at sector 1, it's 2 tenths to find there for you Sector 2 is only a tenth now and sector 3 is another tenth So time to find a bit, 5, 6, 7 and then turn 11 and chicane
Engineer: Lewis, probably best just go for one more lap and then we can get on with the program. I've got lots of tyres to run.
Antonio GIOVINAZZI: Yeah, but we're seeing it's really heavy.
Engineer: Copy that Antonio. Slow in, slow in.
Engineer: No shift, Antonia, no shift.
Engineer: OK Lewis, I suggest we box the end of this lap. Sir, still P1, just a tenth of Valtteri at P2. If we could do some cruises on the way in, so it'll be cruise mode 2, 5th gear, be exit at turn 9.
Engineer: And Lando for the left hand toggle we suggest purple C6 position 3. Purple C6 position 3. And more warm up on brakes if possible.
Engineer: Retardation 211, it's not incredible. OK, we'll come back to you on that. OK run, let's run in BC3, that should help rear temps, which should help retardation.
Naoki YAMAMOTO: How was the car, Naoki? How is the balance so far? Yeah, so far it was a bit understeer, and the big problem was the brake lockup front, especially turn 16, the chicane, the front lockup is easy to lockup.
Daniel RICCIARDO: I don't know what happened, but turning into one, I just lost all the front, didn't feel right, so I went off.
Naoki YAMAMOTO: Yeah, movement, I think not enough front downforce So with us, we should change in front flap Box, box, box, box Stop
Engineer: in front of the garage for flap adjust
Engineer: And focus on throttle application between 13 and 14, where you are now, throttle application, exit.
Engineer: So you can try Funk 2 around turn 11 next lap if you would like. Funk 2 for turn 11.
Engineer: OK, in terms of sector times, we are 2 tenths down to Hamilton in sector 1, 2 tenths down in sector 2, you were perfect in sector 3, and overall lap time was 2 tenths down to Hamilton, currently P3. Kubica behind, time-lapse. OK, just keep me up, yeah, exactly.
Engineer: Engine 1, position 5 if you can
Engineer: Charge on, Dani, charge on. Ok, Dani, on the dash, maximum plus 30, plus 30. How is the balance?
Daniil KVYAT: Yeah, the brakes were really cold in Turn 1 and Sector 1, and then understeer for now, at the moment.
Engineer: Copy. Do you need a flap adjust, you think?
Daniil KVYAT: I think, yeah, I can go a couple of steps up.
Engineer: Ok, if we do a flap adjust now, we have only one more timed, ok?
Daniil KVYAT: Yeah, ok.
Romain GROSJEAN: All in sync, all in sync. Carnage, carnage, need more communication mate.
Engineer: Mostly sector 1, 3 tenths sector 1, 1 tenths sector 2, and 1 tenths sector 3. Suggest in the chicane, third gear. Suggestion, chicane, third gear.
Alexander ALBON: Coffee.
Daniel RICCIARDO: This is the paddocks coming out of the right hand side mirror as well.
Engineer: OK, understood. OK, so we forming adjust and then we go out again, so it is five clicks up.
Engineer: OK, so we're boxing the slab for another front wing adjust. OK.
Engineer: Yep, so that let me know how that tire feels
Valtteri BOTTAS: If
Engineer: OK Valtteri, so that's P1, you've got Lewis starting a lap.
Engineer: I think I need to box,
Valtteri BOTTAS: it's vibrating
Engineer: the front tires now. Copy, so box, box.
Engineer: The main place to find time to Lewis is sector 1, it's 2 tenths in there.
George RUSSELL: Thoughts
Engineer: on
George RUSSELL: tyre prep? Do you think it'll be alright for the first time or not?
Engineer: Yeah, copy. You should be okay on the first one.
Engineer: The
George RUSSELL: sprays seem very cold.
George RUSSELL: That was woeful over the kerbs in the last chicane then.
Engineer: A bit more brake warm-up, Lando behind on a timed lap, three seconds behind.
Carlos SAINZ: Yeah, that was a bit of a late call.
Engineer: Yeah, apologies Carlos. So he's actually doing a timed aerodata lap, he will box so you can open your lap close to him if you want to.
Daniel RICCIARDO: Yeah, front was nowhere, it got worse as the lab went on.
Engineer: OK, understood.
Charles LECLERC: Where am I losing?
Engineer: Losing apex speed, turn 2 and turn 7.
Engineer: Okay, dude really good luck good luck
Engineer: How was the balance?
Daniel RICCIARDO: Still lose the front with steering, but then it made it sharp on exits, so I'm happy to box.
Engineer: Ok, understood.
Engineer: Charge on, box, box, we will make a change on go again. Charge on, box, box. What's the main limitation in the chicane? What can you feel in the chicane? We can see a lot of snaps going back on power.
Naoki YAMAMOTO: Yeah, movement a bit better than previous setup, but still difficult and I feel very stiff. The car is very stiff, especially low speed corner.
Alexander ALBON: We can't double-call this one.
Engineer: I'd prefer one slow lap, I'd prefer one slow lap.
Engineer: OK, that's P7, Carlos. Recharge on is good, and you're clear behind. That lap was with absolutely no tow at all, there's a 40 second gap in front.
Carlos SAINZ: Yeah, OK, it felt draggy.
Engineer: You want me to do a start straight away or only later? Yeah, do a start on the way up.
Engineer: So clutch position on target.
Engineer: OK, let's try to get in a rhythm a bit on the next few laps, at the end of this run we might do a front wing compare, but I'll call you in the air if we need to.
Lando NORRIS: I need more friendly
Engineer: How much more do you need?
Lando NORRIS: One and a half hours
Engineer: Ok, understood
Engineer: There's a small gap behind him, small gap behind him. Box, Alex Box, drive through, practice launch. Engine 7, position 6. Engine 7, position 6.
Engineer: He
Carlos SAINZ: quit a little thing on the rear
Lewis HAMILTON: Something doesn't feel right at the rear.
Engineer: OK, stand by.
Engineer: Okay, and can we have fail, bravo, zero, bravo, off, fail, bravo, zero, bravo, off, and we're boxing for nose change.
Engineer: Checo, so we will be going out again. It's just for flow viz. It will be a single install on the same set of tyres Just caution tyres may be on the cool side and there may even be flow viz coming off the front wing So we just got to be a bit cautious
Engineer: And Lucy, if you can try coming up a couple of steps on diff high speed, let's see what that effect is.
Carlos SAINZ: That'd be the box to save some mileage.
Engineer: Carlos complete the lap if you want, could be wet later, could be wet later. If you're learning complete the lap and push on the in-lap.
Naoki YAMAMOTO: Thank you very much, guys. Working very hard. Thank you very much. I'm so happy and I'm grateful to the team and Red Bull Honda. Grazie, grazie tutti. Grazie, grazie.
