I wanted to say something here but I don't have any references (yet) apart from 40-odd years of thinking about motorcycles 
so I'm talking about high performance naturally aspirated engines here ...
Smaller throttle openings at low RPM actually produce MORE torque than full throttle. That is why you don't fit large carburetors if you want midrange driveability. This is because the higher mixture velocity of a smaller venturi allows improved cylinder mixing and more complete combustion.
In recent times we have seen the move to ride-by-wire throttles and selectable engine maps. This is why modern superbikes can have large throttle bodies and make 230bhp and still be rideable in traffic. When you fully rotate the twist grip at say 3000rpm the ECU does not fully open the butterflies - it gives you an opening that gives you the best useable torque. Previously with carbs (which I love) you had to compromise.
(Of course turbo engines are a whole other area and depend on whether you have mechanical or electronic boost control etc etc etc)

That sure is a pretty kitty! 
I have only just noticed your suspension diagram - that front looks too high IMHO.
You may have already found these but ...
Discussion on roll centres
Discussion on height
The diagrams in the first link look good for scaling lengths and inclinations but it looks like you have already done that.
The second link is more relevant because it shows a setting height that you could use in LFS editor but adjusting the vertical position of the inner pivot. That should give you the correct angle for the lower wishbone (providing the tyre height is correct).
Just some thoughts.

oh ! calling me selfish while not even having bought the game ...
last ever photo from his profile, before he decided to hide it from public access...
bro beated XRG WR with XFG, much slower car overall, is he on that 100 octane jet fuel shit?... he got some pretty good dealers.

I have to take a closer look at that...
I always had 2 devices to choose from - either the pedals or the wheel ... when one of them was activated the other was deactivated, so either the wheel or the pedals were always active, but never both at the same time

New times and drift scores for current Perimeter layout ...
wait?? ... wat?
What to say ... OMG ! insane job guys ! Eric, you rock 
Hope everything is getting fine with your home project Scawen ! Can't wait to put my hands on this masterpiece
. And thanks a lot to share these :
Have some well deserved holidays and enjoy the time before getting onto business again next year !
Nice Christmas present for us, and thanks a lot Degats for those comparison screenshots. I am gonna spend some times looking to these

LFS create backup for transport
I have two computers and wanted to transport, via cloud, LFS settings, setups, views, layouts etc, except large and unnecessary folders as well.
Therefore, I created this .bat file to do it automatically and produce one highly compressed .7z file without the unnecessary folders (you need to have 7zip installed, obviously).
1- Copy what is inside the # # to a .txt file (or download), save, rename to .bat
1.5 - If your LFS folder name is not LFS, replace the ..\LFS\ for whatever your folder name is
2- Place the .bat file in the LFS root directory (...\LFS)

Info: the -xr! is the wildcard to not compress that folder specifically, the search is recursive

Yes, I eventually want to do exactly that. As of the early results posted above, you can take the standardized coefficients as a metric for the impact of the properties. Power influences the performance the most, followed closely by the lift, then it is drag, mass, weight distribution and lastly the engine size.
Indeed, the performance over the course of a race differs quite a bit from a single lap performance. Plus lap counts and pitstops impact the performance quite significantly. I tried to model it in the past for the Open Endurance Cup Five and probably need to rehash some of the ideas to make it work here. https://www.lfs.net/forum/thread/94326-Open-Endurance-Cup-Five---Balance-of-Performance-Discussion
I think getting all the uploaded times may be the real challenge, since I basically naively copy’n’pasted the times from the LFSWorld tables into Excel. For XFG@BL1 there are 347 hot laps uploaded across 14 tables. While other combos won’t have as many uploaded times as the demo combos, it is still a lot of effort needed to do such an analysis.
You can already indirectly get a ranking of the different track speeds by looking into the descriptive statistics as these are practically the mean speeds for each track. It does not factor in the theoretical car top speed. I didn’t look into this, but is the value in the car selection screen independent from the used setup? If so, it would be a thought to include it, although it should prove to be highly correlated with other covariates as well.
I probably would need the whole LFSWorld hot lap database for this.
It definitely would make for interesting facts, but to be honest I probably won’t be able to answer these with what I want to pursue.
You’re right, machine learning is a great tool to do such analysis. However it also is a black box and not easy to understand, why particular results emerge. So I decided to go this route. I furthermore wanted to get practical with JASP.
Basically it is a core thought of this method to make a linear fit but to multiple different properties. The resulting fit will be the optimal estimation for the given data set. I further used the logarithm to be able to get the speed by a product of multiple factors using the following properties:
log(s) = β₀ + β₁ × m + β₂ × p + β₃ × w + β₄ × z + β₅ × l + β₆ × d + β₇ + ...
e^(log(s)) = e^(β₀ + β₁ × m + β₂ × p + β₃ × w + β₄ × z + β₅ × l + β₆ × d + β₇ + ...)
s = e^(β₀) × e^(β₁ × m) × e^(β₂ × p) × e^(β₃ × w) × e^(β₄ × z) × e^(β₅ × l) × e^(β₆ × d) × e^(β₇) × ...
(s = speed, m = mass, p = power, w = weight distribution front, z = engine size, l = lift, d = drag with β being the corresponding coefficients from the multiple linear regression, β₀ = intercept and β₇ onwards being the coefficients of the categoric factors)
I got the latter idea from hedonic regressions in the real estate evaluation. I recently took part in a workshop on that topic. There is a similar situation, where statistical analysis is applied to very heterogeneous data sets to get general models and to reapply them to specific objects. For the application in LFS, there are at least metric values and precise categories, which in theory should make it easier then for a real estate index.

Updated times and drift scores for the reverse infield layout ...
Some more times and drift scores ...
"the daily minimum wage"... how do u want to be taken serious with this ?
many people in rich countries wont be able to afford lfs in a day, check around you. They will just try to save bit by bit to buy things.
Discrimination by money is how all capitalistic economy work.
"No money, no honey."
Get your facts updated.
Restarted working on the cup version ... even though I lack motivation, I will try to finish it.

Maybe just try to create only one car from scratch with blender and import on LFSEDITOR, try to create real physics, engine, animation,... That’s hard! I prefer create something in case of wait about something!
Bom trabalho Carlos! I just came here to say this is one of the best mods i've tried. Great driving, looks, default setup, all lights are working properly and look great, (...). Well done! 4/5 stars for animation (missing the wiper!) 6/5 stars to everything else.
I sent all my purchase information to https://www.lfs.net/mailus, why am I not getting a reply?
