I could make the power no problem…Finding the balance was the major issue. I designed about 3 different cars but only that one fit within the specs… I guess it will just take some more practise, i.e. trial and error, but tips are always welcomed :slight_smile:[/quote]

Having seen your car I can tell that you made some bad choices, that made your car heavier and less powerful than average. On this challenge steel platform with polymer body was the way to go, as polymer is both lighter and cheaper than fibre glass. Also, the big budget allowed for use of mechanical injection, which makes the engine more powerful and responsive.
Those are two things I remember from the top of my head that weren’t optimal on your car.

By the way, race two results are coming later today.

EDIT: Scrap that, I’ll post them tomorrow at some time, I hope

Alright, here are some comments doncornaldie so you can make your car better. Others can apply them as well.

Disclaimer: Those are things that I found work best, your mileage may vary and I might be wrong in some places. Nothing beats experimenting.

First, Quality sliders.

You have a few +15/-15 sliders. In general, negative quality doesn’t bring much. The price difference isn’t that great for the performance difference so I try to stay away from it. As for positive quality, costs rise exponentially but the advantages rise linearly, so it’s often a good idea not to go as high as +14/15.

As for the car in general.

1- Platform.

For platform material, in this case steel or CRES are the best choices, with polymer being the best for body panel. Only use other panel types if you have issues reaching the min weight.
For the body, take you time to choose a light enough body. The problem with the muscle car body is that it is very big and heavy.
Also, don’t forget to add wing+lip for downforce.

2- Engine.

For the internals, I usually go for forged I-beam and forged pistons by default, since they let me rev fairly high and keep the engine reliable.
Your head and block material should always be matched, or else you will get a reliability penality. While a Iron does give slightly more HP, IMHO it’s not worth it due to the weight penality, especially since that weight is located in the front.
The optimum values for ignition timing are usually between 70 and 85. You can get a bit more HP by rising compression instead.

3- Trim.

It seems like you tuned your transmission and suspension, which is great. Just stay away from negative slider values.
For the brakes, make sure they are large enough that you don’t too much brake fade. For this, check in the details for your tameness rating. I usually bring it to +10 and then adjust until I find what seems best.
For the tires, make sure to the run the best tires that are permitted, and if there is a maximum quality, you should be running that tire quality.
For the interior, make sure not to use insulation, although it does make a decent ballast if you are slightly under weight.
And run all the assists that are legal.

Points noted and are being considered. It will take a little time to fully understand the cost to balance ratio mechanics of the quality sliders since i’m fairly new to the game. I did first make a lightweight car but the cost was just too expensive after i was completed, so i scrapped it.

I’ll try out some of these configurations and see what I can come with. Thanks a bunch guys, I really appreciate the tips :slight_smile:

Here we have, as asked, a chart with all the cars engines and layouts.
Also, the power, weight and power to weight graphs.

The first step to a light car is a light body. The hatchbacks and the two smaller boxy cars are usually good choices.

For reference, in the first ATCC, in the top 5 you had 3 boxy '60s cars, 1 CRX body and one 5dr hatch.

146

So i went back to the drawing board just now with the help of strop, trackpaduser and the rest… Shaved about 10 seconds off my laptime and saved around 7,000 dollars which i could then spend on the engine. I might do some more tweaking with the extra money i have now. thanks again guys :smiley:…check out the new version…did the track in 2: 23 compared to the last car which did 2:32.

Those graphs really show just how good the level of competition is. Several users here probably had to use better than minimal interior to make the weight (insulation in a race car? How decadent!) For the first time, almost pretty much ever, I don’t have the highest power to weight ratio, let alone anywhere near the top of the pack!!! :open_mouth: Furthermore my car body is one of the larger, heavier ones, so that it did this well on a medium fast track is interesting (I was expecting a bit worse), then again, minimum weight restrictions really evened out the playing field. Once again well done Leo on making a compelling set of rules and premise, the turnout is evidence of its success.

I love the unpredictability of such tight, high level competition as counterintuitive approaches can become dark horses. I’m completely supportive of the moves to publicly share general principles and tricks that make the competition even tighter, too.

@strop

At one point during the design process my car had 4 seats. I even tried to use a radio as ballast, but it wasn’t as good as using insulation.

Right now it has 39 insulation and +3 interior quality.

Also, I am surprised that no car has significantly more HP than mine, since I know it is easily doable.

But it’s pretty easy to see that power isn’t everything, there are only 3 entries over 500hp in the top 10, and only one over 510.

@doncornaldie

Dude that’s awesome. Also IMHO it now looks much nicer. Is it still NA?

149

So… I’m horribly under powered!
I just went back and re-tuned the gearing and shaved several tenths off my time. I really should have maxed out my budget in quality sliders as well, given that I had over $6000 left.

Ah well, 26th isn’t too bad for my first time in ATCC! :smiley:

150

Making a car light isn’t my problem. Making it powerful is.

Of course, I think we’ll see later on that the Kaminari is one of the cheapest cars in the competition. I just gave up with a ton of money left because I couldn’t figure out what to spend it on that would give any significant gains. Like, I was at the point where I had to burn $3k just to get 3 HP.

151

I’ve reworked my car… but my V8 i think was a bad option comparing to the 2.0 Turbos… i only improve some seconds my laptime in Suzuka and need near ten to catch podiums, but well is all i can do.

-Installed 4WD system
-Added better aero parts
-Retuned the engine with 30hp more
-Some modifications in gearbox, suspension, etc…

And it isn’t accepted, as stated on the original post.

NO REVISIONS!

Hope you guys understand that this takes time and I don’t have much at this time.

Edit: doncornaldie only made his cars for fun, he didn’t sent me, something that you,ViruTypeR, did.

153

Sorry for that, i was trying with money briefcases but no way lol.

154

No problem. Next season you can make use of this new knowledge :smiley:.

[size=50]However, how big was that briefcase again? i MIGHT be able to make an exception :stuck_out_tongue:[/size]

[size=150]Race Two: Bahrein[/size]

Here are the results for the Bahrein track, filled with lots of straights and high-speed corners, and a couple of very, very tight ones.
Here power and high-speed balance were key.

So here are the lateral acceleration and drag coeffcient graphs. Out of these you can see who had tons of wings, or none at all, and also who is best at making a car balanced.

And the results, this track hasn’t got a built-in tameness penalty, as Suzuka does, so a few of the uncontrolled rockets were able to have very good results.

Wow, no wonder I am near the back. I have no where near enough downforce or cornering in my car.

156

w00t?!? 13th place, faster than leo?!? 8 points… I’m glad! First time scored at ATCC

157

Let’s hope the points keep coming because I am going to get wrecked on BRC stage 2, and probably Brands Hatch and the track whose name is impossible to pronounce.
Looking at the current results and at the cars, Pyrlix and Strop are probably going to get good results there.

I am also surprised my car did this good on a fast track, as I had an other build that was faster than it on fast tracks.

158

Wow, my car is pretty unusual after all, only Inline 4 car, 0.5+ hp/kg, and aerodynamic as a brick :laughing:

159

Hey! :stuck_out_tongue:

I’m pleasantly surprised at 5th in this stage, actually. I just went back and had a look at the build and discovered a massive amount of fail in my build: apparently while only a medium sized water intercooler was available, I could have used a large air intercooler which would have given me, wait for it, 534hp :laughing: And gone faster on almost every track (except probably BRC stage 2 and Leo’s extra bumpy special VIR). That’s what I get for habitually preferring water intercoolers!

Will not forget to do that next time :unamused: Oh well, live and learn!

Still N/A and with a shorter stroke lower CC rated engine. Still working with strop to make it even better.
