To be able to do free practice 1 and 2 with one engine and swap for free practice 3/qualifying and race engine, one will first have to take a second engine from the pool of three, and taking a second engine from the pool of three, it will be registered as having been used once it crosses the pit-lane-out line.aleks_ader wrote: ↑07 May 2019, 21:13I believe teams do FP to Q swaps already. But yeah is complicated for the crew etc. Indeed it is very early in the season as it is normal procedure. I guess Ferrari had issues with 1st batch of PUs this season. Hence the reason why they speed up spec2. I think they figure it out that spec1 cannot reliably run on max settings. Or at least they saw bigger gain on long run with early spec2. And they can run spec 1 in less power depended circuits. Or on FP on couple of races.
The track was repaved last year and laptimes dropped a lot so this number must have gone up significantly. This year turn 2 and 3 will be easy flat and turn 9 will also be flat.henry wrote: ↑07 May 2019, 22:06Spain is quite low demand for full power:

Good point. How much difference do you think that will make? I still think Barcelona is at the lower end of power demand, although maybe the number of full throttle straights would be a better discriminator.Juzh wrote: ↑08 May 2019, 09:08The track was repaved last year and laptimes dropped a lot so this number must have gone up significantly.

Last year it was ~46s at full throttle (100%, not 90%). This year, with higher drag and most likely inherently faster cars in high speed turns, it'll probably be a few seconds more. A bit below 50s is a safe bet for this year. If we assume 1.15.5 for pole time, then 50s would make for 66.2% of 100% throttle.henry wrote: ↑08 May 2019, 10:04Good point.

I remember this was already reported back in 2017 but maybe this time it's finally true or still just some persistent rumour For sure they won't say anything officially.LM10 wrote: ↑08 May 2019, 18:03Article from Franco Nugnes and Giorgio Piola on italian motorsport telling that the spec 2 PU is gonna have steel pistons, after 2 years of experimenting. Article also mentions 3D metal-jet printers that allow creating objects of composite material which would have been complex to do in traditional fusioning processes.
