BRC: Shakedown Challenge [FINISHED]

[Dragawn]

Cooling has a big disadvantage because it makes the car have a very high drag coefficiënt

Also, if someone's interested, I'd like to cooperate with someone since I prefer to focus on making an as tame and as powerful engine as possible for the next challenge, and leave the model and all other fuzz to someone else

Thanks for that, you're a champion. I really didn't think being limited to 15 inch wheels was going to count against me so badly, I guess that car body isnt meant to be a race car haha. I will make brake cooling a priority in future I guess.

Might I suggest an overal cooling limit in future this may balance braking power and aero more easily than a massive rules list? Say you have a cooling limit of 1000 on the car body an n/a car would be able to utilise more points I brakes and aero than a more powerful turbo.

Limiting the cooling would be silly, unrealistic, and just an extra field to add to Der Bayer's work. The most you can really do about turbos is limit the turbo/compressor size or add a turbo pressure limit, and doing any of those currently would be pointless, as turbo sizes are already limited heavily by block size. Boost pressure would also be ridiculous as it'd only hurt the engines with smaller turbos, because the big ones(due most likely to the current header limits) will never exceed 2.0 BAR or so in pressure, which is already below the MODERN real life WRC turbo pressure limits.

I could team up. I can't design an engine as competitive as those.
Not that I am very good a car design eiither but there I might stand a chance.

[OCAdam]

An interesting challenge might be to allow same size engines for NA and turbo... but NA uses 91 octane unleaded while turbos use 80 octane unleaded. Though I dunno how much effect that would actually occur (or if it'd be too much!).

[Der Bayer]

The easiest way for balancing turbos and NA would be to adjust the capacity limits. This will be taken care of. Turbos still will be more powerful, but - as I said previously - the focus on driveability will increase, too. This will make it more balanced. Just look at pyrlix' performance in Stage 3: P4 with an NA engine. I don't like different fuel types, another thing that can be done wrong. And the effect is not much different from limiting the capacity.

I'm currently thinking about a team challenge in the next round: A team has 2 players and they can build their cars independently or use the same platform and engine and just different models (not sure about that yet). The quickest time per stage will count. This will offer the following strategies: Win the team championship with one car focussed on high speed stages and one focussed on slow, bumpy stages (or however you want to make you cars) or build a good allrounder for the driver's championship, where only your own times will count. What do you think about it?

[gt1cooper]

So you can either be scored by taking your best time of the two cars entered per stage using a traditional rally system, or by a points system a la F1?

[Der Bayer]

If you participate in a team, you will be taking part in both the driver and the team championship. It's all about time, no scores. For the team, only the stage time of the fastest driver of the two counts.

edit: the 2nd driver in a team must be another person, it's not another car built by you.

[Dragawn]

Can you put a NA engine in one car and a turbo in another? Or will there be limitations on differences between the cars?

[Der Bayer]

I have not decided yet. Either both cars will use the same platform and engine or they will be totally independent form each other. What's your opinion?

[Dragawn]

I'd say same platform and same engine block. Otherwise it'd get a quite dull competition of building the best NA car and the best turbo car.

[Der Bayer]

Either totally same engine or totally different. I'm not willing to check every car for it's engine block (and note down how it was built to compare it to the teammate's engine).

[gt1cooper]

I like the idea of having the same engine and platform, with different tuning. That seems like an interesting idea; that is what my vote goes to.

[Reaper392]

If you went ahead with that idea I would be worried that it would put off the single person entries because they would be at a huge disadvantage on individual courses, since the teams could have two more specialised cars whereas people working on their own would only have one car that they could enter, which would almost certainly be slower than the team's best entry in all courses. It might make the overall drivers championship interesting though, since both individual drivers from a team will probably not do as well as a single entry.

[Dragawn]

Well, in my opinion exactly same engine would seriously limit potential changes. I think that this challenge has proven that the biggest change is made by what's under the hood. What about all NA or all turbo? Would that be easier to check?

If not, I'm completely fine with same engine.

[Der Bayer]

Single player entries ("allrounders") still would be good on average stages (and of course in the overall single player ranking, it's not really about winning stages).

Limiting to both NA or both turbo would be possible. The question is: Can this be exploited? Basically it would be possible to strap a turbo with 0 bar boost to the engine, just because the teammate has one for the fast stages. And "turbos must at least have xx bar of boost" is a rule I don't really like.
