PRC - Professional Rally Championship Dev Thread

Oooh…you replied before I could change. Put lbs instead of kg

Does this mean you are now prohibiting partial Aluminium panels?

I get that Magnesium isn’t exactly a commonly used composite. But why disallow AlSi?

As far as engine block and header compounds go, AFAIK (feel free to correct me if I’m wrong) AlSi has been around for nearly 2 decades and is more common than Aluminium by now.

I take it we will be restricting width at some point too. Actually, wider tyres are bad for rally, so that’s one of your main challenges: finding out how to use the offroad stat to determin how good a rally car is.

I beg of you, please don’t make ALL the sliders 0. That kills off about 75% of the variability and complexity of this contest given how restrictive the rest of the regulations are. The rest of the restrictions are pretty reasonable.

What you’ll probably want to do, however, is definitely put a maximum tech level on the tyres. Stipulating a minimum safety level is pretty reasonable, though be careful with this, you don’t want to mess up our ability to alter the weight of the car further!

Seeing there’s no reliability rule, i’d be going straight for half cooling to get some of that much needed aerodynamic bonus for less drag

I was waiting for that to be discussed in the scoring mechanics portion :upside_down:

Well just for you…I’ll make sure there is a reliability limit in the next draft :wink:

Looks good, still think a budget restriction would be better than restricting quality sliders (other than, say, +5 tires).

I would use actual weight instead of minimum weight, otherwise it means you HAVE TO go for a 1200kg 300bhp car to be competitive (so, less variance between the submitted cars)

Also, I would go for a displacement limit instead of hp limit; hp limit means you have to go for low-rpm torque to be slightly faster, which isn’t really what a race engine should be.

For the cost limit, $50k (I assume that’s total cost, not estimated market price) is too much, the cars from BRC are $5-7k in the current stable and you could go quite high on quality sliders.

Category 5 racers from SOF are 10k budget, and they go WAY off the reservation with their power outputs. Just so you know.

Also P:W is a good way to ensure competitiveness, just don’t limit the weight then.

^^^^^Looking good. I have a truck ready to start testing when all is ready

Is there any production year restrictions, 2016?
fuel type?
fuel mixture restrictions?

Not for Season one.

i want people to have a wide variety of bodies to choose from.

The only thing i need to add is no mods allowed

No mods? I’m out.

Ooh, that’s probably one of the first things you should mention if you’re going to make a contest: mods or not, and how flexible you are to change this. Are you running standalone?

I mean, most of us who use Steam can probably simply click the option to disable the Steam mods, and that’ll solve most of the issue, but it’ll also suck out a lot of the enjoyment from building cars, because most of our visual content actually depends on the really good mods.

I am very flexible, just not sure if i had to download all the mods myself. My laptop isnt the fastest…

If its that serious i am willing to reconsider :wink:

No mods is good for me, as I’m the kind of person that really doesn’t like dealing with mods - but if most people want visual mods (that don’t affect competitveness too much) its to consider.

Thats a good compromise.

Visual mods only - I will add it to the regs.

Ok so your best bet is to download the HQE pack and stipulate to use this only. My computer is ancient and I have all the steam mods each only takes about 15sec to download and install. If you are going to host challenges I highly recommend downloading all the steam mods it makes life so much easier
