Hi everyone!
 
I make cars for Richard Burns Rally videogame (my mod will be downloadable for free), I am looking for torque curves for various rally/race cars (and front/rear % weight distributions/height of center of gravity/Cx coefficients/wheel weights etc, game uses a few hundred parameters in it's physics system). For rally/race cars this site gives nice detailed specs including various gearbox ratios etc but no TQ curves as such
 
 
For stock cars I've found this site interesting (after choosing a car you need to click various "Show detailed specs" buttons, there are torques given for each RPM)
 
 
First question - what was the real torque peak for Formula1 McLaren MP4-4? Was it 424 Nm? Surprisingly it's hard to find this info (I guess there was also qualification mode).
 
There is also a mess with available data for PCWRC 2003 Mitsubishi Lancer Evo VIII and Subaru Impreza WRX STI N11, stock data is mixed with rally-prepared versions, what was rally tuned torque and kerb weight for both? I've also found such gear ratios, were both using 5-gear gearboxes?
 
Subaru
R -3.545
1st 3.166
2nd 1.882
3rd 1.296
4th 0.972
5th 0.738
 
Lancer
R -2.707
1st 2.928
2nd 1.950
3rd 1.407
4th 1.031
5th 0.720
 
I am also interested in Pikes Peak/Group B cars, WRC 2003 / WRC 2011 era TQ curves, Group A/Kitcars/Nissan Deltawing/LeMans/Indycar/Australian Supercars V8/Nascar/Rallycross/DTM/Dakar etc so basically I would be happy to grab any graphs/links you can share with me (especially outputs from real dynos if any of you insiders can send it anonymously if its secret haha ;) I want to recreate https://en.wikipedia..._in_Formula_One but no detailed specifications about it anywhere.
 
Here is some stuff I've found 
 
Torque curve for Peugeot 208 T16 Pikes Peak from dyno

Moments of intertia/center of gravity positions from NHTSA tests with real cars (I also need such values for game simulation). You can download OpenOffice sheet here https://megawrzuta.p...d139f07308.html (green "Pobierz plik" button)

Avon tyre data (also stuff used in simulation) - multiple files here https://megawrzuta.p...f41ff00681.html

And scans of Lancia S4 book with setups used in real car - files in high resolution here https://megawrzuta.p...d2c38c0d0.html 
 
Of course I am interested in real setups, I've found very interesting blog from Anthony Warmbold http://wrcbehindthes...springs-co.html (I made gravel setups according to his clues). I wonder about caster differences for gravel/snow and tarmac. Anybody knows WRC 2003/2017 wishbone length? I am also curious about drift setups : big steering angle, big caster, front toe-out, whatever-to-rear-axle which induces oversteer?

Thanks in advance for any help!
