BRC - Out of the Steam - 1945 [Final Race Results]

[Tycondero]

Fear not, the times in BROBOT simulation and the times given by the automation simulation don't match up! In the pre-testing it seemed to be quite a bit faster in the BROBOT...

Wait, thirty seconds faster? That amount of improvement would put my car ahead of the fastest entries from the first test run!

Isn't that also because the car doesn't need to start from 0 mph/kph when passing the finish after the first lap? In Automation you always start from 0 mph/kph.

The Automation Test Track has an extremely short pit straight coming off a tight right-angle turn and going into a narrow chicane - I'm pretty sure a flying start is only worth about six seconds. (The video runs at 3x speed; first lap for the #1 car ended at the 56 second mark; second lap ended at the 1:40 mark; arithmetic.) JasonPoland's results imply that BROBOT cuts laptimes by another 10% or more beyond that.

Double facepalm into deskpalm...why I've forgotten about this?!

Looking over the video, JasonPoland, your car gained a lot from the flying start, but still less than ten seconds. [Edit: Green flag for your car was 2:20; crossed the starting line for the first lap ~2:22 (note: even the 'standing start' is slightly faster than in-game); crossed the starting line after the first flying lap ~4:19 with a 174.67 lap time; 117-119 seconds of video equals 351-357 seconds in-game; 351-175 = 176 and 357-175 = 182. So a flying start gains you something in the ballpark of one to seven seconds - or, using your fastest lap of 173.66, two to eight seconds.]

Well...let's just say that i had to rebuild it from scratch...and it's faster

Sweet.

Due to the running laps you save a lot of time that would otherwise be dedicated to accelerating. If you have a really long 0mph to 60mph time of say 20 seconds you could shave off around 10 to 15 seconds with running laps. Meanwhile if you have a faster 0mph to 60mph time of say 10 seconds you would only save around 5 seconds on a running lap.

So now this style could open up new gearbox ideas less focused on the 0 to 60 acceleration and more focused on a 50 to 75 acceleration to accelerate out of the corners better.

This makes me want to redo my cars gearbox now.

One funny thing, I had to redo my cars engine because I accidentally calculated my HP to Weight ratio as HP/LB and not as HP/KG. I had to derate my engine by around 50HP. Cool thing was it cut 6 seconds off my lap time in game by doing so.

Genjet I did the same thing with my power to weight, I was running 300hp now I'm down to 125 but it only shaved about 2 seconds off at the airfield.

If you want to test your gearbox on a flying lap you could try sector three a brands hatch it is a whole flying lap.

This looks like good fun! I might give it a shot.

[GenJeFT]

Where is the sector three a brands hatch thing? I searched for it and the only thing that popped up in the search was your post.

Also, by reversing the HP to Weight equation I now know about what your car weighs (around 835kg).

[sniperbait636]

Here is the brands hatch>http://automationgame.com/phpBB3/viewtopic.php?f=36&t=4202&hilit=brands

Also 832kg to be exact I rounded up my HP its really 123.

[GenJeFT]

Ooo, very close on my guess of your cars weight.

I ran transmission tests using my car that I entered in the contest.

The different transmissions were inconsequential to lap times. Differences were less then 1 second and for my car that one second was in the wrong direction.

[sniperbait636]

After some quick testing I was only able to make a few thousandths, to bad I was hoping for at least a tenth or two.

Good That gives us a chance to catch up LOL I will say though that the field outside the very top and bottom is quite close, I think test 2 will be much closer.

Is there a tutorial on .lua files on the forum somewhere that I am missing? I can't seem to find them.
