IMO it’s better to do the former, 120kW for 3 seconds, so long as the 3 seconds you choose are at the the lowest possible speed. Three 1 second bursts of 120 kW at the start of straights are better than 12 seconds of 30kW along a straight. This is because at higher speeds most power is used to push the air out of the way.subcritical71 wrote: ↑Tue Aug 14, 2018 12:22 pm

Is it better to do 120kW for 3 seconds, or 30kW for 12 seconds(?).
You’re absolutely right. As would the first few laps of the race. In Q they might consume as much as 12MJ maybe a little more, but in the first few laps of the race the sky’s the limit. The bigger the battery the higher the sky.
Can you prove it with, ahem, calculations?henry wrote: ↑Tue Aug 14, 2018 5:47 pmIMO it’s better to do the former, 120kW for 3 seconds, so long as the 3 seconds you choose are at the the lowest possible speed.

Provided linear everything, 3s of 120kW could cut the lap time by more than the alternative because the average speed will be higher for that particular duration. I know it's never really this simple but it is my understanding that the preference is to accelerate faster over a higher top speed.restless wrote: ↑Tue Aug 14, 2018 7:14 pmCan you prove it with, ahem, calculations?henry wrote: ↑Tue Aug 14, 2018 5:47 pmIMO it’s better to do the former, 120kW for 3 seconds, so long as the 3 seconds you choose are at the the lowest possible speed.

Say, you have 20 secs of max power, which will be faster 3secs of 120kw or 12 secs of 30kw?

It's how Red Bull won Monza several years ago. The gearing they used was short. Their top speed wasn't great but they got there very quick.hurril wrote: ↑Tue Aug 14, 2018 7:22 pmProvided linear everything, 3s of 120kW could cut the lap time by more than the alternative because the average speed will be higher for that particular duration.

I'm thinking everyone can deploy 120kW to the MGU-K for at least a few seconds on each straight. So the equation then becomes at say 150+kph, what is the best strategy. I'm still thinking 120kW all at once, vs smaller increments but their may be tradeoffs with the first scenario (cooling, for example).hurril wrote: ↑Tue Aug 14, 2018 7:27 pmExactly!dren wrote: ↑Tue Aug 14, 2018 7:26 pmIt's how Red Bull won Monza several years ago.

I did a little calculation. Very basic.restless wrote: ↑Tue Aug 14, 2018 7:14 pmCan you prove it with, ahem, calculations?henry wrote: ↑Tue Aug 14, 2018 5:47 pmIMO it’s better to do the former, 120kW for 3 seconds, so long as the 3 seconds you choose are at the the lowest possible speed.

The engine could always do it. It's more reliable now so they can do it more often. Squeeze out more power using engine tuning, lubricants, fuel. The ICE is the big differentiator in qualifying.Gr1ff wrote: ↑Tue Aug 14, 2018 4:30 pmHow do you explain the sudden increase with no change to kimi's ice then?PlatinumZealot wrote: ↑Tue Aug 14, 2018 3:20 pmThis! 100%!saviour stivala wrote: ↑Tue Aug 14, 2018 12:26 pm
The FERRARI horsepower gains are not electric horsepower gains but are produced by the ICE (combustion).
The Electric horsepower is limited.
It acts through the MGUK and only develops in duration of usage.
The ICE is where Ferrari is doing the damage.
Is that a typo or does Run 2 deliver a faster speed? I ask because, and I know I need to do my own calc's - I'm just too busy/lazy at the moment, but it got me thinking it may be better to ramp the 120 down over a period of time as speed increases....
Faster speed. But the objective is not speed it’s distance covered.subcritical71 wrote: ↑Tue Aug 14, 2018 10:24 pmIs that a typo or does Run 2 deliver a faster speed?
