Automation Touring Car Championship 2 [FINAL RESULTS]

[Leonardo9613]

There are NA cars with more than 500 hp on this challenge, the recipe to them is very straight forward.

Use a very short stroke and good bottom end parts, then use DOHC 5v and cam profile set to max, the key thing here is to give a lot of quality, therefore valve float, and the drop in power it causes, will happen later. Once you add the possibility of revving higher and a good exhaust, you should be good to at least 470 hp.

Mine has exactly 470HP and it's a non Turbo 3.5L, so what Leo says is true

[QuantoSolo]

Interesting discussion and yes, Leo is right. What I have to figure out now is how to close the gap in tameness for turbo engines without sacrificing too much power. Drag penalty for added cooling on the car still remains after all. On the other hand my best efforts to squeeze the last bit of power out are so far still short by roughly 40 from that mentioned 701 hp, although I don't know if that engine is more expensive still, so I might try to reach the top, and clever use of quality and funds available, before starting to try to refine the results. Though, all could be so much more easy* if we wouldn't be forced to use same size turbos even on engines that come biturbo by default.

*For a given value of easy. It would mean 3 more sliders for the second turbo after all and a chance to draw a camels back by boost curve.

Do you know the problem with having a fixed turbo?
Tests.

I would have to spend (even more) time balancing the requirements and how the championship would work. Besides, it would limit the possibilities of the championship, restricting creative approaches and increasing development, with no fun bonus. And the worst thing would be the complaints, they would say that it isn't big enough or that it is too large, etc, etc.

I based these rules on group A's original set of rules, but turbo restriction or cooling limits weren't considered for long.

Part of me is a bit...anxious, even though I'm trying to just simply not be too caught up on one end.

I suppose since this is my first actual entry (sure I've tried with engines but not this), that's one reason, but I suppose since my entry only has just over 450bhp.

I put emphasis on a chassis over an engine, in spite of how reality and expereince suggest that I need to be absolutely on spot in both areas. But I guess we'll see.

I didn't go the turbo route initially because apart from what headaches I went through, I didn't find what I got to be all that 'useful' but then again this is speaking more as a (virtual) driver than an engineer. I like a broad power range and low end torque so if say I were to exit a corner in a higher gear than what's expected, I'm not in as much trouble compared to if the engine in my car, was set more for higher end power.

Then again, apart from how it's been pointed out to death that the turbos in this game aren't quite 'modern' even if you go up to modern day build years, I likely still suck hard at putting together turbo motors with an ideal power curve (and can run fuel between regular and super unleaded). This is just me rambling though.

One more question...anyone here even bother running catalytic converters? one may say it's pointless but I partially blame the 'eco' mentality in me, but also given my entry represents my car company, and these are meant to have some relation to some road cars in time, I figured I'd both 'practice what I preach' and this can be a useful experience for future race cars, even if it means a power disatvantage.

Since it's the late 1980s I don't use a catalytic converter. I don't think they were used in real racing back then either. In years where the sporty metallic/high flow converter is available I am tempted to use it though, but decided against it in the first ATCC as well.
Don't worry about turbo, I went turbo just because I wanted it. It fitted better into the idea I have for my still non existing car company. Tests showed that on all tracks but the speedy ones (well, 3 out of 5 tested) the NA version was faster, had 485hp NA available back then though, and overall seemed to be the better choice. Chassis is still one area I still don't know what I'm really doing, so more power might help. Or not if the added tameness would help to fix the weaknesses of the chassis better than power succeeds in trying to cover it up.

Sorry, my post was misleading. I didn't meant restrictions by the rules of a competition. I meant the limitation by the game that both turbos have to be of the same size on a biturbo engine. Although I'm not sure since when different sizes of turbos are used in real, or as biturbo with V engines at all. The V8 being biturbo already helps though, with an inline single turbo engine things are even more difficult.

I think that for equality you should point to a limited power/weight relation. About 500hp per tonne or so. What do you think?

I don't use 5valves and i could improve the engine, but i preffer to do a good chassis.

There's a minimum weight limit, which keeps the entries relatively close in HP/KG, so long as you make an nice motor. From that point on, it is just up to tuning the car.

Sent my entry in, hope all goes well. I'm definitely feeling underpowered and overweight, I hope all that time spent in the wind tunnel will be enough to compensate...

[Leonardo9613]

First, I would like to remember every one that there are only two days remaining for entries!


However, I must announce, this time there won't be the trump cards.
I am too busy right now, due to moving between houses, and I prefer to continue with the original schedule than to delay everything and make the cards.
The reason is the sheer amount of time it takes me to do it all correctly. On the last ATCC, I spend roughly 6 hours doing all the 37 cards. I don't have that time right now.

I will however find a solution to display Conan's brilliant comments on the cars though. The stat comparison graphs will also be made since they demand very little time, now that I have all the data.

Damn that's a nice looking car. Nice headlight work.

"Nice headlight work"? Not sure if sarcastic, that took me all of five minutes to set up, hahaha?

@leo: DW, the tables and charts are the bulk of the info! If anything, all you'd have to do is release the power: wt chart first, and then all we'd be missing is the snide remarks

[Weasel]

So, here is my orange beast for this challange.

It's called Currusgenus (engl. car race). This is my first Turbo Engine for a Automation Challange ever. So, enjoy it.

Very 80's looking front end there
