The diameter increased 10mm to 670. 680 for rain tyres.hollus wrote: ↑Sun Apr 23, 2017 7:30 pmThese are the ratios for the data I have processed so far:Mercedes (3rd to 8th): ----- ----- 9.812 7.965 6.572 5.645 5.072 4.472 Ferrari (1st to 8th): 13.641 10.342 9.607 7.909 6.739 5.762 5.043 4.469 McLaren (2nd to 8th): ----- 12.367 9.667 8.068 6.900 5.882 5.118 4.519I am assuming that the diameter of the wheel has not changed and is still 660mm, is that right?
I intend to process the other teams eventually, but it will be slow, specially seeing that probably there is nothing earth shattering to be found. For once the rules did what they were supposed to do and gearing is a small performance differentiator.
Thanks for this info. I posted this at another thread, but it looks like what I found fits your idea of a compromised 5th, 6th, 7th and 8th gearing as a patch for the resonance issues.hollus wrote: ↑Sun Apr 09, 2017 6:59 pmAdded McLaren:
The 8th gear is significantly shorter compared to Mercedes and Ferrari. It might look like a lot in the graph, but we are talking about some 5km/h differences here, so it is not world changing.
The big question is whether it is shorter because they do not expect to reach the same power as the other two teams or whether it is a patch for their resonance problem.
I am inclined to believe more in the second. Their 7th, 6th and 5th gears are also significantly shorter, it is first by 3rd gear that they fall in line, and I am sure that McLaren are expecting to have similar cornering speeds to the other teams.
Something I learnt looking at the onboards from McLaren: they are shifting up at impossibly high revs so that the car is almost never below 11000 rpm, even not after the upshift. It is only out of part throttle sections that they are at 10xxx. This goes some way to explain the lack of power and, in some way, fits with shorter gears. By shortening your gears you get to be at higher revs for the same speed. This makes intuitive sense, although I am not sure it makes sense if one thinks analytically.
Certainly they have the best overlap in the middle gears, again not sure what this means or even if it means much at all.
In any case, teams are allowed one change of ratios this season, so I was kind of expecting McLaren to have compromised their first set to cure whatever illness the engine has right now, and to introduce the second set once the vibrations are gone. There is nothing utterly bizarre there, though. Time will tell.
