2019 Scuderia Toro Rosso F1 Team - Honda

It was a good practice for STR Honda today. best of the rest.
I wonder how much the front wing contributed to this performance ??

[TimW]

Str in Gasly hands out qualified rain master Max in Hungary last year,the Rbr is not particularly good in the wet .they are lot of cars in the middle fields who don't have particularly good aero but are not fighting at the front in Monza

Last years red bull was terrible in the rain, diffuser stalling was the issue iirc. This year the red bull is fine in the rain as Germany showed.

oil leak for Kvyat.

The PU is over?

I saw how it was smoking heavily in the following circles, so the engine most likely died, unless the security system had time to turn off the engine, but turbocharged engines need some time to cool after stopping (turbo timer). I wonder where the oil leak occurred, on the side of the Honda (motor) or TR (radiators, pipes)

[Marti_EF3]

The PU was still running when he stopped. And it sounded normal. At best the PU is safe and no more penalties. We'll have to wait Honda and STR to explain what happened.

It's unlucky for STR today, Gasly compromised by Stroll early on. Shame for Kvyat, he could have been 4th.

4th? Why stop there. Maybe he could have won.

Smoke could be hydraulic oil ,gearbox oil or pu

Yes, you're right ... I hope you're right.

Maybe you need to return to the Mclaren thread if you're here to post nonsense stuff

Not really relevant to the topic but turbo timers are used with turbos that are oil cooled. Water cooled turbos do not need a turbo timer. I suspect the CHRAs on these PUs are water cooled.

Yes, I know this, I just applied the general concept. But this is Formula 1 where the loads are exorbitant. The oil and turbine are most likely cooled by a liquid radiator, in any case you need to pump oil or coolant after an abrupt stop at high speeds, otherwise the temperature will rise sharply at first due to the stop of the cooling system. Fluid convection after shutdown should occur on its own, but can it instantly cool bearings in oil to a safe temperature that has already stopped? Hope so. In any case, in F1 the most ingenious engineers and the best lubricants, I think they thought everything through.

I suspect the turbos are designed with potential for quick shutdown in mind. The worst part about a quick shutdown is the oil coking and I would think the oils they use suffer less from this. I would be more worried about oil starvation of important bits. I hope they got it shut down soon enough and that the oil leak wasn't the result of a failure.

That would not be good news for spec 4.

I also hope so. In an interview, they said they told Kvyat to stop as soon as they saw a leak on the sensors. I hope the pressure has not dropped so much and the leak did not come from the main nodes.
