BriSCA - N.A.C.O. - A.C.O.N. Stockcar F1

[Junkman]

This is one of my scratchbuilding projects. It's still in a very embryonic phase.

[dwc43]

Off to a good start so far. One thing, the wing is kinda wrong. Drivers side should hang down and passenger side goes up. One other thing that I think ight look better is to change your front bar. Have it run with the frame over the coil over mount and then down to the frame. But, it does look good and can't wait to see the end product.

The wing is correct, this is England.

I cannot change the axle/frame/coilover layout, because this is how it is required by BriSCA rules. This is how the real ones are built.

Ahhh, I see. British rules... lol. Still look like it's off to a good start though. I was at Hobby Town about an hour ago. Saw a 40 Ford kit that is made for an open wheel dirt or asphalt car. I thought about getting it to make something sort of like you have started here. Your build has inspired and got my mind working on something, but I need a plan first .... lol.

Oh, talk about coil overs, have you seen these. http://www.rbmotion.com/shocks.html

Dying to buy a set to try out on something.

Holy sh...moly!

Gosh, I will have to sell my children if you show me more of this.

As for the axle/coilover/frame layout:

The rulebook specifies two straight beams that run the length of the car. Mind you, this is a contact formula, so the frame has to take quite some impact. Hence, there are no kick ups front and back to accommodate proper mounting directly to the frame.

As for the wings, I think they are more a hindrance than a help and disputed them quite a bit during the past 25 years. I have a basic sense of aerodynamics. But to no avail. This is how a guy in Scotland makes them and it is impossible to talk the racers out of them.

How about the home page. http://www.rbmotion.com/index.html

Check out the acorn nuts and lines and fittings and nuts and bolts. And get this, it's a new web site and they aint finished adding parts to the list yet as I understand it.

As for the wing, It seems top heavy and with a rear driver position and mid engine it seems like it would make it very loose in the corners compared to out World of Outlaw cars that are a shorter wheels base with the fuel tank in rear making the engine sit more forward.

Not sure what I will race this year. Nashville wants to do away with the race track and fairgrounds so I want have anywhere in towing distance to race my NASCAR Gran National Sportsman car. I still have two of my old dirt track cars that I could rebuild in short order. I also have some F body Mopar chassis that I could build up to run SCCA road courses with. And that is what I am really leaning towards doing. I ran some a few years ago with some pretty good success right out of the trailer.

A stockcar F1 cannot be compared with a sprint car. The stockcar is two to three times as heavy (minimum 1350 kg, on non-paved tracks there is even ballast added to the cars), yet tyre - sorry, tire - threads may not be wider than eight inches. If you don't make it lose, you go fencewards. And I talk fences here. Some English tracks retain what is known as 'post and wire', or vulgo 'cheesegrater', as the outer boundary.

Here is some typical shale action:

Note the shale type wings as opposed to the tar type wing on my model.

Also note that contact is by no means avoided.

Here is a track with post and wire fence:

And here is tarmac:

Thanks for the vids. That is interesting to say the least. Not sure which I like the best, asphalt or dirt. Now I just have more questions. Engine size ??, tracks look to be 1/4 mile or so. I did like to see them get 'em a little sideways on the dirt though.

This is very short and not a very good video. It's from a small camera. It's a Chevy Monte Carlo at the Music City Motorlex during a practice session. This is a G.N. Sportsman car. 5/8 mile banked track. Chevy 350, Ford 351, Mopar 360 all on stock stroke crank, stock length rods, max overbore of .070. Run about 120 130 off into the corners.

These are Late Model dirt cars from my local track of Duck River Speedway. I've raced against a few of these guys. These have pretty much run what you brung engines.Unlimited pretty much. They can turn a 1/4 in 12 secs.

There's a shot at the front of this one showing a guy grooving the race tires for these modifieds

One more.

By the way, pay attention to them coming off the corner on the back straight. You can see them lift the LF tire off the track. They do it on both ends, but they seem to tote it off the ground longer down the back stretch. Could be because this track has two different corners compared to other tracks.

Here's a link to Duck River speedway. http://www.duckriverspeedway.com/

You can find the rules there and a link to pages with pics if you want to check them out. I tried to find video of what they call the Stock or Super Stock cars. I used to drive them too. They look more like your everyday car with heavy mods for racing. You can read rules for yourself on that class though.

1/4 mile would be considered a long track. Sheffield is 390 yards and it is by no means the shortest track in the country.

Engine size is unlimited, but all out out-cubic-inching each other is a thing of the past. Shale cars nowadays have around 500CI, and tar cars usually run small blocks.

I'll have a look at your vids shortly.

Wow, now that's short track racing there. Hope you like the vids.

your scratch building is spot on. I really like your work on this one...Robert at RB Motion is top notch and if your not careful you can spend a weeks salary with him. Ask me, I know...

[dwc43]

you can spend a weeks salary with him.

Tell me about it. I'm trying to work up a good order between paying the bills .... LOL!!!
