They come from Ferrari Power Unit thread: viewtopic.php?p=781167#p781167Dave P Fanclub wrote: ↑22 Jul 2018, 13:52That's really interesting (and plausible) atanatizante.

But it`s interesting to see why they are ahead now, isn`t it?
I don`t buy that 28kW/38HP AMuS argument due to at least 2 factors: they don`t have access to the team's data and secondly, they can`t do either simple math or don't have the knowledge (for instance, once they said that Ferrari has increased their ES from 4MJ to 4.4MJ in order to gain 28kW but when you do the math you could see its rather 4.93MJ ... then they bounced from the presumable 120+28kW=148kW to 150kW saying that means 201HP instead of 204 ...). So it's not the first time they didn't give us some reliable info ...
Toto said they are now gaining some 5 tenths on the straights and that is not due to Ferrari`s 38HP gain as it`s almost impossible to achieve these days in such a short frame of time and there was a quote in AMus from an advised person how said that this amount of HP could be reached only in 2 years development time ...
He identified 2 elements which are responsible for that gain: TC and MGU-H and all the odds are favourable for the latter. But normally this costs the engine too much power because of the exhaust backpressure and Ferrari has found a way to reduce the power loss of the ICE due to their Shell investments in combustion with TJI, HCCI and so on technologies. But that`s not all. Furthermore, Shell has done his homework for a more important aspect: fuel formulation or fuel calorific power hence more HP. So they are ahead of both combustion+fuel side and from MGU-H side for allowing them now, presumably, 120kW constantly both in qualy and maybe even in the race. And that's the reason why they don't need to harvest so much via MGU-K as AMuS said.
This progress on ICE side is translated in better traction out of slow to medium corners and that allows them to alter their deployment strategy with no more time spent out of the corners (like everybody team does) and now being solely for the straights. That explains why after 200km/h (in Merc case) Ferrari`s speed is going upwards towards top speed sooner, coz their deployment is doing longer times than the opposition. And that`s the reason they are gaining time on the straights coz they could stay longer on top speed ...
And that`s not all. Having a speed advantage in the straight (not to be confused by top speed) this allows them to have a bigger RW AoA hence more DF out of the slow and medium corners.
And finally, they have better starts out of the line also due to having a better traction and that`s another proof for their progress in combustion & fuel side ...
