  • Oval track ???

    Anyone know a good place to get oval track layouts? Banked and flat if possible. I want to build a replica of Bristol Motor Speedway.......or as close as possible anyway.

    rough dimensions for scale Bristol

    Corners are 20 feet in diameter and the straights are 27 feet long, so the footprint would be 20 x 47 feet, roughly. This is for 1/24th for 1/32 multiply by .75, straights are banked 16 degrees, the corners are banked 36 degrees. But, if you built this track to these dimensions, you would not need driver's stations because it would be flat out, full throttle all the way around. Or you could just rubber-band your trigger full-on. This would be true with virtually all slot cars from vintage Carrera Nascar stockers to Group 7 wing cars, even though the latter are about 15 times faster than the former, because the "fast" cars are built for speed + handling.

    A 1/24 lap would be 117.26 feet, a 1/32 lap about 88 feet per lap.

    Scale versions of real life tracks NEVER work. That said Martinsville would be a better model, but still not very realistic. The straights at Bristol are 650 feet, at Martinsville 800 feet which accounts for the "paperclip" nickname.

    Standard oval track dimensions for mile dirt tracks are ---- straights are 1/4 mile long and each corner is 1/4 mile.

      I have been thinking about it, and yeah, an exact replica would be pointless. The track we race on now has 11 1/4 ft straights and 6 1/4 ft flat curves. Its fast, but I think a little more challenging layout would be nice. I was thinking of a tri-oval maybe to break up the "full throttle" action.

        If you want to avoid constant full throttle racing just up the voltage a little. Even an extra half a volt can make a difference with non-magnet cars. At higher voltages it is a good idea to reinforce the car's chassis at the guide flag.

          Make your corners tighter maybe? We race on a 4 x 20(ish) oval, I think it is, with banked curves. You need to lay off the throttle a bit in the corners. Very fun racing with 6 folks. Especially the close races.

            try a smaller but faster "oval"
            check out www.rmscc.co.uk
            The cars are what we call "stock cars" i think you call them sprint / open wheeled modified
            Have fun Ellis

              Hi rookie208
              Most pro track builders are happy to build an oval banked or flat - or just about any other shape you want - at a price.
              Alternatively build your own routed track.

                Well I guess....good a place as any to ask.
                How many lanes work well on 4' x 16' oval?
                I need to get to building a track that can travel. Thinking 1 4x8 sheet for the 2 ends and 1 sheet for the straights. That way the track can break down and fit in my pickup.

                  Sounds like Crab Alley Speedway

                  in the Baltimore area. Exactly what you describe, a traveling 4 x 16 four lane oval, although I think 3 lanes might be better. This is for 1/32nd only, too narrow for 1/24th.

                    Here's my 7'-6"X 16 oval. It's mounted on a trailer for racing to go. These pics were taken during the Nor Cal swing of the 2010 Forums Cup Proxy. I towed the track 150 miles one way for this race.


                    The D section is a lot of fun to drive on. It's fast, pretty much flat out, except braking into the next turn can be dicey until you get the hang of it.


                    3 3/4" lane spacing allows closed fendered 1/24 but it is a little too tight for the large scale open wheelers. It has a small road track in the center for a little break from oval racing once in awhile.
                    D's are cool!
