SKG's tracks

[SKG]

One day I will actually make my tracks drivable in a sim, but it is not this day! A longer circuit this time, with the full circuit length just under 6km. The east (blue) and west (black) configs work well, I especially like the simplicity of the east circuit.

In terms of the style and feel I was going for, imagine Road America with a few $$$ spent.

Configs in next post.

Here's a simple, short circuit inspired by Mantorp park (https://youtu.be/RRRJyrcT7uY)

2.2km anticlockwise, with a short oval (0.5km / 0.3miles) suitable for legends or similar.

There aren't any very tight corners, and the 800m back straight (~) should enable some good slipstream action.

Only 10 turns, its nice to simplify now and again...

Brilliant highly detailed graphics as usual.

For some reason all I want to say it reverse it, not sure why the only thing that sticks out is that the short straight from the double 90 on the left might work better at the end of the back section rather than at the front.

I think you'll find Legends would love to race on the full length circuit, at 2.2km it's essentially Knockhill sized and they slipstream/bumpdraft there no problems. so unless you were thinking running BRisca Stockcars or similar I wouldn't bother with the oval.

You are probably right, I know nothing about legends racing! BriSCA seems like it could be suitable. Looking on their website their ovals are mostly around 300-400m long, as opposed to 490m for my design, but it could work I guess..

When I sketched the circuit it was originally anticlockwise (see highly detailed sketch below), but when I started sketchup-ing I changed my mind and reversed it. Then I changed my mind again and un-reversed it. No regrets!

To be honest, the overall shape and corner shapes of Mantorp Park look to me like it could just as well be a street circuit layout in a fictional city.

I've been working on this for a while. I originally wanted to get it finished before the Indy 500, oh well..

This is an oval inspired by both the Indianapolis Motor Speedway and the Talledega Superspeedway. This oval has banking of 15deg in turns 1-4, 7deg in the short chutes between turns 1 &2, and 3&4, and 10deg through the tri-oval/finish line area.

The blue configuration (oval with chicanes) would be good for high speed, hard braking testing, while the white and pink configs offer alternative road courses which utilise the oval "pit road", in contrast to the green grand prix config which uses a pitlane on the straight between oval turns 2-3.

The back straight is flat to allow for a grand prix grid.When the grand prix pits are in use, the inside wall is moved away from the pit buildings and towards the track edge to form the pitwall.

Roadcourse barriers and tirewalls are in place as usual, but not shown are the SAFER barriers, which would encompass the entire outside wall of the oval, and on the inside at key places.

A great concept and great imagery. Just one thing: the paddock space of the oval paddock seems too large / out of scale for a 2.6 mile oval when compared to the GP paddock on the backstretch. Also, how much seating capacity do you think you need for such a circuit? More than they have at Pocono?

Thanks for thinking these through - and for the original design, of course :-)

So many high speed curved braking zones and strange kinks.

The paddock may be slighty oversized. I imagined the seating near the start/finish and turn 1 to be for oval racing, while the stands near the Grand Prix pits are used for road racing. (Obviously, who wouldn't want to watch races here? )

Thanks for the comments. It wasn't originally meant to be this complex!

Could you specify the areas to don't like, maybe ways to improve?

Thanks

Well, since this is doing so much good just sitting on my C drive.

Adding some tarmac to smooth out the transition off the banking (removable kerbs can make the circuit do whatever the series wants a la Indy road course).

Added a small slab of tarmac to allow a u-turn directly before Turn 2 to go back down the oval pit-out, allowing a slightly extended variation or chicane the oval T2 .

Used the existing tarmac on the back straight to delay the u-turn for the full roval so the braking zone is free and clear of T2.

Completely rejigged the infield to make smoother and faster, with easier return to the banking, primarily to make side by side racing easier.

This one looks really nice. I think it would be interesting and challenging to have NASCAR races there. It would add some more diversity to the types of tracks that they race on. Any ideas on where it would be located?

Somewhere is NASCAR country devoid of a superspeedway? Where do you think it could work? I'm not too hot on U.S. racetrack distribution...

Sorry AOB, I still prefer my design, I think the flow is better and more interesting. The track is quite wide (15m) so I'm not sure the extra tarmac would be needed. The square bends would still be quite quick as it is despite the small radius.

On the subject of scale, the back straight you drew is the same length of the Sepang pit straight, and I'm not sure having such a fast corner at the end of that straight is the right choice.

Also, I'm not happy about the 100% kink-removal. Embrace the kinks!

Thanks for the reply though, I appreciate the feedback!

After thinking my BTB file was broken / gone forever, my Track 64 project is back on! I decided to go straight into building the circuit for rFactor, and skip all the usual details I put in using Sketchup.

Taking inspiration from random junk, this circuit is based on a small piece of wire I saw lying around on a rainy day. After trying two designs, I settled on one and Sketchup'd the basic layout.

Unfortunately the spiral at the end of the back straight didn't work out, with yellow flags displaying and invalidated laps every time I drove through the tunnel, so I tweaked the design to add I nice open hairpin, a great overtaking opportunity.

There's a youtube link below of a little test race I did, apologies for camera phone quality. It's WIP, plenty of scenery and adjustments still to be completed.

I believe the circuit is around 4km long with a laptime of around 1:25 - 1:30 in a GT car.

Darn It! I quoted the wrong reply. I meant to quote your original post. I think the track is fine just as you designed it, not as AOB said it would be. As far as places that lack adequate NASCAR facilities- anywhere in the Rocky Mountain States (Colorado, Wyoming, New Mexico, Montana, Idaho) and the Cascade States (Oregon and Washington). The rest of the country has plenty of speedways.

Boulder or Denver in Colorado could be interesting. At that altitude (~1600m) you could lose over 100bhp, according to an online calculator I've just found.

So, instead of running a 280hp restrictor plate, NASCAR would only have to run a 160hp plate. Although a test would be advised before race weekend, just to make sure!

Ahh, that BTB screenshot makes me re-discover the beauties of track designing...

(and the very first track I drew as a young teen, was also based on a twisted piece of wire...)
