the link is this
https://www.fia.com/sites/default/fi...2020.12.16.pdf page 92 Using a sim games mod tool, I'll try to recreate the torque/power curve as suggested by that graph |

honestly I still can't understand correctly that target power curve... because you know... it simply goes against physics lol...
you can see that according to the target curve and the table at side, the max power release increases constantly up to reach the top of 500KW at 95% of max torque peak release (0.95 N/Nmax)... then once it reaches 97.5% and 100% of max torque peak, the power curve of that graph is supposed to decrease! but that's basically impossible because increasing torque after top power is already reached, power will keep on increase as well! if an engine gets 500KW at 95% of torque release, at 100% will get >500KW anyhow and not less as this graph. The peak of torque (basically value 1 of N/Nmax) is always reached before the top power, small-mid NA engines reach the peak of torque close to the peak of power at higher rpm; large NA engines and turbo engines usually reach the peak of torque at mid rpm, however before the peak of power, because it's how things work... That power curve growth layout is basically the one of a mid/high-rev engine, likely NA, but values of N/Nmax torque are wrong... it had to be something like 464-475KW reached at 1.0 N/Nmax and top 500KW at about 0.85 N/Nmax. Or it's something I just can't understand or it basically doesn't make any sense... unless N/Nmax means something else unrelated to torque release, but if it was, why engine speed is indicated with that and not with a rpm range table according to possible rpm revlimits as happens with IMSA bop sheets? |

It clearly says that column is engine speed and N/NMax is just a dimensionless fraction, I don't know why you think it must be Nm.

I clearly see that on X axis there is engine speed, but what does mean N/Nmax as dimensionsless fraction, or maybe you mean friction? can't understand the correlation

Its confusing to say the least. All in the name of equalization. Regulating power curves is a lot to undertake just to level the playing field imo.

Interesting that later on that page it says they will correct the curve for conditions! So if we are, say, at altitude there will be no loss of power and and turbo v. normally aspirated differences won’t show. Must have a decent look at this doc at some point. |

Thank you... to be honest, % of rpm range was what I thought at first but then I saw N/Nmax and thought was something related to % of torque release.
Hope ACO and FIA will keep on showing onboard telemetry to see how high lmh engines rev. ICE TS050 was revving up to about 8000rpm according to that |

have IMSA and ACO decided who will be the spec kers supplier?

Williams could do quite well in Sportscars if they gave it a go to be fair. I just hope the KERS system that Bosch and Xtrac develop with them is up to standard, it will be tough job doing it for everyone

Why will it be tough? and why do you express a concern that it might not be up to standard?
Seems a good choice as they got experience. |

Yeah, the guys who build such things for a living would not be able to meet the demand for what 15 cars?? I'm thinking that isn't even a challenge to meet demand

Perhaps they could practice by supplying batteries to Formula E for a few years?

Actually that’s not the worst idea ever. The question is whether Formula E would want them to

Looks like Pagenaud may be up for one of Penske's Porsche seats:

Besides the availability of IMSA-spec hybrid system, there's a question of homologation. Do LMDh cars get "frozen" in their debut spec for 5 years like the LMH? This could be the big factor in Porsche's desire to test ad nauseum ignoring any 2022 WEC (even Le Mans) debut opportunities and get it 110% right before Daytona 2023.

Yes, 5 year homologation. Has to be same as LMH to make any sense.

no surprise, back to about 10 years ago, porsche was already testing 919 on june 2013 to debut on april 2014, before final homologation I think a manufacturer could test his LMH/lmdh prototype even 24/7 for months
