BRC 1966 - Gentleman Brobots Club [RACE 6 P&Q]

[Der Bayer]

Yes, that was my current idea, too. I will update the Tool today, but if you want to work with it right now, please try removing any file or folder which is not a .lua file from Cars/Trims, Cars/Models, Engines/Families and Engines/Variants.

The tool wants to read the ID from any file in the folders and if it can't read the file (because it's the wrong file type) it will crash. I didn't expect there to be other file types.

oh dang.... after chasing all that times. i forgot.

how will rain affects those with slicks and those with sports tires? (and if someone is nuts enough, mediums?)

[strop]

Oh, I think I know what my problem is then! I didn't finish cleaning out old files from previous builds and I note in the log that whenever I start up Automation it has difficulty with a great deal many of my files but otherwise works fine. I'll flush them out and see if this fixed my problem.

EDIT: wait, no, then why would 3 of my 4 BRC test builds work just fine and this particular one that I actually want to send it not!?

[UMGaming]

Mine does 2:23.83... And honestly I have no idea how I did that ._.

I predict that your gonna have some tyre wear issue's If you are going that fast.

That is why God...I mean....Der Bayer, created pit stops! And I am actually going quite a bit faster than that.

I remember from the video something about switching to rain tires, if it is raining. Otherwise......screeeeeeeeeeeeech...CRASH!

[Der Bayer]

Yes, you can switch to intermediate and wet tyres. If you have chosen semi slicks your tyres will wear faster than if you had chosen medium or sports compound.

The Tool has been updated. Please download again if you had problems.

I've deleted the "old" and "thumbs" folders from engines and cars folders and now i can load any car!!

EDIT: with the old tool

EDIT 2: the new tool won't load the trim with the "old" and "thumbs" folders also... but if i remove them, it works fine!

Der Bayer
if this

tyre wear: make pit stop when average tyre wear exceeds specified number ==> at % tyre wear 20

is set up at 20% (as default), does is mean that stop will occur when there is only 20% tyre life left of 80%?

And does tyre degradation leads to slower lap times or more chance to crash? Aaaand also what are damage effects (or maybe better how severe are they)?

[RobtheFiend]

The tool doesn't like "Caps" , my name is exported as " obthe iend". Looks very strange.

[Packbat]

Off-topic, but I figure I should let people know just to minimize future confusion: I'm actually a trans woman. I figured it out late 2014, but I've been taking my time with coming out, because I abhor awkward conversations. I know it's almost entirely irrelevant to the competition, but I figure someone is likely to refer to me with pronouns sooner or later, and they might as well be the right ones.

Anyway, on to the actual topic: ponies.

I mentioned before that I wanted to build an FF or RR car for this, but when I decided to build an FR Trans-Am car on a lark, I ended up with this rockstar right here. It's not got the highest top speed of the test cars I built and it's not got the best cornering, either, but it's close - and it's got almost zero tyre scrub at any speed, relatively mild camber front and rear, 275 horsepower from an all-aluminium 3.3L V8, and a big enough tank to run 90-minute races with only a single pit stop for fuel. I'm feeling really good about it.

Hopefully this will be the #33 car, that being my finishing position in the 1955 BRC.

Sorry, no pony.



Riso Motors Hornet GT66R.
Mid-engined 226 HP V12, 908 kg.

I don't know how my car will perform on tyres and fuel so I just set two pit stops at default lap 20/40.

No, I don't like the headlights that much either but there's hardly a place for them on the fender. Racing cars also don't need indicators.

[Packbat]

(a) I love that body. Didn't use it myself, but I love it. (And yeah, the headlights are a bit dopey, but that's cute. )

(b) Remember pit stops are at percentages - if you're having two, they should probably be at 33 and 67, 35 and 65, 40 and 60 ... something like that. The defaults are set up for a 4 pit stop race.

(c) Reposting my formula for estimating fuel consumption:

  Code:

    Estimated Race Fuel Consumption [in kg] =
                 (Time of Race [in hr])
                 * (Engine Economy @ Max Power RPMs [in g/kWh])
                 * (Engine Power @ Max Power RPMs [in kW])
                 * 1 kg/1000 g
                 * r

...with r likely in the range 0.44 < r < 0.61 for low-fuel-consumption tracks like the Automation Test Track (point estimate 0.52) and 0.53 < r < 0.75 for high-fuel-consumption tracks like Norisring (point estimate 0.64).

You can eyeball the numbers from the in-game graphs or read off the exact numbers for engine economy and power from the Results/Curves section of the engine variant .lua file - example:

  Code:

       Results={
          AdjustedAFR=12.75,
          AverageCruiseEcon=453.43594397352001,
          BaseEcon=338.99330784286002,
          BaseTorque=293.31209796106998,
          BaseVE=0.93100000000000005,
          CoolingRequired=88.864391049931996,
          Curves={
    [...]
             {
                6500, -- <-- this is the engine RPMs
                199.28471402951001,
                135.65301510020001, -- <-- this is the power in kW
                523.85505501344005, -- <-- this is the economy in g/kWh
                23.536122865397001,
                RPM=6500
             } --[[table: 0x0f26e668]],
    [...]
          PeakPower=135.65301510020001,
          PeakPowerRPM=6500, -- <-- this is the RPMs for peak power (i.e. the RPMs to check in the Curves, above)
    [...]

To get fuel tank size, open the Trim .lua file, search for "Footprint", multiply the dimensions, divide by 10000 (m^2/cm^2), and multiply by 7.

(Using the most pessimistic estimates, my car's race fuel consumption would be 118.5 kg - one pit stop on a 61.2 kg tank.)

[Riso]

That's a very informative post, thanks. Might actually cause me to retune my engine for better high rpm economy!

[AirJordan]

Thanks for the info Packbat! if you are correct, I can almost do a race per tank can we part-refuel?

[RobtheFiend]

Just refuel on the first pitstop, new tyres on the others.
