    That sounds good what about a 1500bhp or even 2000bhp car, the 2000bhp car would have to be "Mostro" and the 1500bhp car would be "Mini Mostro"

    i had a jab at an electric bolide torque curve was right but no matter what i do beams power curve is the same (near the redline)
    my turbo bolide is awd with a wee bit less power ~800hp dozen psi but the main problem with beam right now is how cars stop tracking straight past 200 mph so currently cars have to be overpowered to reach top speed without veering off...

    no abs tho just in typical Italian fashion.... unlike the 200 psi semi

    I have one but i am not happy whith ( i have to make the rear suspension a lot harder and the spec are not beleavable for the moment...) .
    --- Post updated ---
    For sure the temptation to have for wheel drive is big because this turbo car is almost not driveable, but i whant so something possible , and in the 90 , some crazy tuner put 1000hp on a ferrari testarossa ( i ever drive a stock 512TR it is not easy to drive it fast , so with two big turbo's i can't imagine) ....
    Cf : Koenig or Hamman Testarosa 1000hp (must ear the sound ...)

    Its pretty simple to throw a brushed DC electric motor in any BeamNG vehicle. Done it on multiple occasions. Might I ask what curve you are using? A brushed DC motor has a perfectly linear torque curve with peak torque being achieved at 0rpm and a perfectly flat gradient down to no torque at a maximum RPM. If a motor is given with a peak torque (or with motors its more typically rated as a stall torque) and you can also confirm its torque at any other given RPM (often the hp figure will be given at a certain RPM, you can therefore calculate the torque at this RPM) its fairly simple maths to work out the maximum RPM you wish to use with it in BeamNG.
    AC/BLDC motors can also be done easily, although their torque curves are not always as linear as brushed motors and their controller hardware can often do some incredibly funky stuff, I did find data for a tesla model S and stick that in game once though.

    a small ramp up so the gearbox doesnt freak out idle as some low non 0 rpm and drops offs as it gets to redline
    although the power keeps going up until the redline torque drops off after a few 1000 rpm (10k redline)

    Mind sharing your data?

    i have a electric sbr i may release it if someone is interested ? (i don't do this way for the troque curve but i'm maybe wrong)

    Bam, did a bit of a hunt:
    [0, 415],
    [7000, 415],
    [8000, 350],
    [9000, 290],
    [10000, 250],
    [12000, 200],
    [14000, 180],
    [16000, 50],

    is the relevant data for a tesla model S, off top of my head I dont know if thats the upgraded horsepower model or not, I dont think it is. This is off of published data, it is an AC/BLDC motor with some complex electronics operating the thing so I think that is why there is some torque limiting at low rpm and why the torque after 14000 or so plummets.

    The P85d is more than 700hp an 930nm of torque :) My torque curve is way more simpler , but it's hirochi one ;)

    something like this
    mind you its also awd
    motor limit is 12k vs the tesla's 14? but redline is 10k
    [0, 0],
    [50, 400],
    [250, 750],
    [500, 1100],
    [1000, 1200],
    [3000, 1200],
    [4000, 1100],
    [5000, 1050],
    [6000, 1025],
    [7000, 1012],
    [8000, 1006],
    [9000, 1003],
    [10000, 1000],
    [11000, 500],
    [12000, 0],
    it may be a wee bit strong i dunno
    power curve goes from 0-~700 kw at redline

    "idleRPM":100,
    "shiftDownRPM":2700,
    "shiftUpRPM":9700,
    "maxRPM":10000,
    still has sound tho
    "gears":[-2.00, -3.12, 0, 3.12, 2.00, 1.00, 0.9]
    "clutchDuration":0.00

    Yeah having a look online, my figures are about 10-20% below what they should be (maybe I was drunk when I read the graphs) then the p85d is dual motor hence double output torque. That makes some more sense now. Throw in some extra tuning, 930Nm seems rather believable
    --- Post updated ---
    Yeah totally off from what an electric motor would achieve. No electric motor type *gains* torque as the RPMs increase like that. It looks more like you've plotted a power curve rather than torque.

    If we took 12000 as the max rpm with 0 torque and maybe 4000 rpm and its 1100Nm of torque as the important points. If this was a plain brushed DC motor I'd go at:
    [0, 1650],
    [12000, 0],

    and be done with it. Idle RPM can safely be 0.

    my sbr-4 elec is :
    [0, 900],
    [6000, 884],
    [14000, 0],

    Because is suppose (maybe i'm wrong that with the rpm , the electric motor loose a little)

    i was just giving it a built in limiter before 1000 rpm
    http://farm9.staticflickr.com/8227/8593664014_6345b3daa1_b.jpg



    problem was the speedo wont work like that (with the idle at 0)
    only the debug showed rpms
    i would drop the torque off more but there wasn't enough power if i dropped off more at 4000

    ps
    "inertia":0.1,
    "friction":10
    "brakingCoefRPS":1.0
    "burnEfficiency":1.5
    "throttleSensitivity":1.00
    "viscousCoupling":50

    "burn" cause beamng uses gas :p range may be a tad high too but it has "regen"
    0-100 in <3 sec

    Put the idle to 1 :) I send you both in pm my electric car
