My Tracks

[crozier74]

Yeah, I suppose we haven't discussed this one yet, have we? I quite like it actually Would have prefered the original proposal, minus the chicanes, as it's of more reasonable lenth than the current one, which is a bit too short. But as a start, it's all right. Let's hope the event runs smoothly, and maybe the event can grow to encompass more international classes, although we wouldn't want too much competition against Macau. Changwon's already diluted the Far Eastern street track mix, do we really need another?

[Mike_Wooshy]

looks intresting, depends what the road surface is like i heard they are only going on the street course as bernie signed a contracted to be the first big event on the shanghai track, well thats what i heard. But china have wanted a V8 series hosted thier for ages, they went after the V8 supercars for a while.

[Melaneimoon]

well you say its shorter than sepang & catalunya, so about 730 metre ???

Well no, regardless compared with other straights. How long do you think is good for that circuit?

[Mike_Wooshy]

730-850 mark obviously you want them to hit a good amount of speed, but to long & it will be boring, i think theres no real point having a straight any longer than a kilometre (1000 metres) as engines will start to strain at top revs. (i think with piston engines its about 23,000 RPM maximum, as i dont think physics laws will allow any more than that from a V engine which has over 100 moving parts) anyway the engines will blow on the straight alone if its to long, let alone the rest of the race, ala hockenhiem before it was tilked. only time you need anything longer than a kilometre is when testing the top speed of a ROAD car where the aero dynamics arent as good as an F1 car so it takes longer to get thier. (obviously). I jsut dont understand why in F1 they use a rotary engine as it can rev higher for longer.

[Mike_Wooshy]

by the way im working on a track from that will comply with fia circuit regulations, can anyone point me in this direction as the only rule i know is the circuit much have a kilometre straight ending in a hairpin. its why tilke gets alot of jobs he builds tracks to fia standards.

[Mike_Wooshy]

lol okay 3rd post, but kylamia in south africa has been sold to some people theres more in the trackside part of 10/10

[Melaneimoon]

But what about the existing F1 circuits without the straight and hairpin?
For regulations, I recommend the FIA website at www.fia.com
where you can find a PDF file (Appendix O) about Circuit regulations: http://www.fia.com/sport/Regulations/circuitregs.html

[Mike_Wooshy]

well not all ar built to fia regulations, not all need long straights & hairpins, silverstone, brands hatch are circuits like these, havnt got big sraights and hairs pins, flowing corners where accleration control is the key. the abbey chicane provides good over taking & okay theres a straight but the key to over taking thier isnt speed its how good of a run you get out of club which is thus determinded by your entrance to club, hence why if you make another driver to make a mistake going into club you can get a nice run & on the breaking you got him. same with paddock hill at brands, theres a straight but its corners before that help over taking not the striaght then the hairpin.

well, Bahrain isn't in my F1 2000 game yet ofcourse... so I couldn't really tell...
Anyway, what's your suggestion for the length of my circuits' straight?

Like the Hanger Straight at Silverstone maybe?

Thats a load of ****...

The rules are actually not too limited on the face of it until you start working with them. Like, "the corners should flow nicely" what kind of rule is that?

You can find stuff on the FIA website, I believe its Appendix O to the sporting regulations, I'll check

( DOH! I should have read Melaneimoon's post! )

Pirenzo, i like outside the oval you can see the brands hatch influnce thier, but inside the oval, its too cramped. but i like outside the oval. btw i throught barhian was 1000 metres exactly, while shanghi was slightly longer than 1000 metres, but catlunya & sepang are 800 metres, i think.

Why do people keep pointing out Brands influences?!
I didn't design it with that in mind at all. Which bits are ya talking about anyway?
Bahrain, yes your right, its 1090m, just checked.

[Mike_Wooshy]

i think this bit looks like brands only in revers :x

[pirenzo]

Here's a much better version.

Western Ave has been re-routed under the whole facility, and although not shown access to the infield taken via secondary tunnels offshooting from the main one.

[crozier74]

Looks distinctly Estoril-ish But better than the first IMO

[pirenzo]

yeah, Estoril type track is sort of what I was aiming for. But with two banked corners onto a 1000m straight
Hence the copious run off at the first corner.

[Mike_Wooshy]

much better ! yes estorilish, very nice better than what another oval has done to its infeild *stairs at Tony G*

[Lustigson]

Very slick, P.

[Lustigson]

I'm just curious, P. What are your criteria for choosing either gravel or high-grip tarmac as run-off in corners?

It seems that you use tarmac for corners which cars approach at a higher speed and gravel for slower ones. I think I'd do it the other way around.

[pirenzo]

random

[pirenzo]

Though, I don't think its really a high speed/low speed entry thing.
If you go straight on at a corner from outbraking yourself, tarmac is better becuase you won't bog down, but then you shouldn't be off the track in the first place. If you have a gravel run off into a high speed entry corner though and you've got a car with tyre failure for instance, it will probably roll when it goes through the gravel, which you don't want. So I would say for slow speed corners where silly errors can occur, tarmac is best (or for really slow ones, grass even) and for very high speed entries tarmac is best, and for medium speed corners where you tend to get spinners and outbrakers gravel is best because it provides the best all round stopping capability.

[pirenzo]

Finished it off a bit. Rethought the run-off situation too

[Chaynes321]

P, send that to the FIA, lmao, its super!

[Chaynes321]

A new nose for McLaren, its Ferrari-esque ... (ie more conventional)

[Purist]

The Brands Hatch and Silverstone examples don't really apply when it comes to Tilke's designs. Those two courses were around and in use by F1 long before the current rendition of Appendix O was formulated. Of course,. the FIA has a certain propensity for neutering even the best of the old courses. To bring them more in line with their vision of what is best for whichever series is going to run there.

The main straight at Sepang is just under 930 metres in length (either 927m or 929m).

Hmm, I see no one has done a tri-oval for the challenge.
