That seems like rubbish, everyone is opening the 'gates in qualifying as much as they can anyway and using battery to keep the MGU-H spinning.

They should be doing it as much as possible during the race, too. They just have less ES to e-charge the ICE during the race. Honda said they ran much of the lap that way in 2016.

In the race you want to keep the pack topped up, in qualifying it doesn't matter.

Over the course of the race you need to extract as much mechanical energy from the fuel as possible. Opening the wastegates to use electric supercharging wastes fuel and should only be used tactically.

Just an idea - IF they leaking oil trough turbocharger (bearings) then spinning it artificially by the MGU-H will generate more "spills" of the oil into the air intake, therefore more energy to burn by ICE...

This maybe the way how Ferrari's boost mode is working.

Yeah even simpler venturi effect should make job done.

Supposedly it is just when the turbo is cold.

When the turbo is up to temperature the seal expand and less oil is lost.

That causing thd cloud of smoke, this is a way how to "control" the amount of oil used and also the timing when to use it...

So somesort helix grove should do it.

Remember oldshool helix oil shaft seals: Just reverse the intention.



So any engine gurus so how would mapping with that concept work. Is the oil : fuel ratio is somesort proportional with volumetric flow? That should be douabble,

EDIT: i mean with RPM of shaft. Indeet they could timed with turbine and compressor efficiecy curves to suit the fuel : oil ratio needs.

In these turbos are ceramic "bearings". Ceramic ring, shaft and between is just slim layer of oil...

If it's oil that's burning, why the smoke is white and not blue?

Yes indeed right i think that also. Still doesn't prevent to use "magical" hybrid system to achieve that. Heck they even could have there just for "bearing" cooling. So yes doable and legal if its done right (not obvious). Like Toyotas "ingenius turbo restrictor cheat".

"Incidental" leakage into the compressor is allowed but if it is found that this leakage is manipulated to get more power they will be sanctioned obviously. I don't think Ferrari is doing this because for one when the turbo spins faster the leakeage is less. Not what you want for high power.

If they were using this for more power they might try to hide the smoke, too.

Burn little oil, blue smoke
Burn allot of oil, white smoke.

What is "little" and "a lot of" oil? If we consider 0.6 l as little and we don't see any smoke on other cars, shouldn't Ferrari then be using a hell of an amount of oil?

What's more, the amount and color of the smoke was the same in testing already. Why would they use much oil in testing? Same goes for free practice on race weekends when the engines are turned down. Still the same smoke.

Also, it would not be intelligent from Ferrari to make such big smoking visible if it came only from burning oil. They would have looked for another solution, thinking the smoke would cause a stir and make others investigate it precisely.
