Whats next?

i have wandered about going to a down tube chassis , with a bar running from the top , right corner of cage , to where top of right front shock is , kind of like a sprint cage , with the load being applied to the right front these days , less flex might help......TNT built one like this several years back....

I have had two modifieds that I have added an adjustable bar to from a down tube to the rf stub by the shock. It made a very noticeable difference playing on the right track situations by stiffening or letting it flex more. I am not sure though on the late models now how much you need that with all the other adjustments with shocks, tires, springs setups, etc... and no big heavy stub. But, another trick in your tool box I am sure is always helpful.

Charlie Swartz did that 30 years ago. Had them on both left and right, from the top of the cage forward to the upper shock mount. Ran it half a season before he cut them back off.

The hand writing is on the wall, it wont be but about 5 years or so and these Chassis will have to SFI Inspected and Certified. Just like Drag racing, Certified to there level of competition. Their doing it on seats now, wont be long. SO that's gonna leave the door open for new designs and materials, plus more $$$

You could go all Tig welded, stress relieve them etc. I see the Chassis cost reaching 10k bare easy.

LOL on the XR1 Fuel Cell too ! I about fell out of my chair, I think that would be a good business to be in !

things have changed a whole bunch in 30 years , the load that is placed on the rt upper shock mount is tremendous when you consider when momentum begins on a soft spring and basically comes to an abrupt stop when it hits the bump stop or second stage.

Mr. K , I think what you are talking about above would be another nail in the coffin for SLM,s , no average , do a lot of it your self racer like me , would ever be able to afford this , we need ideas within the means as a whole . I do think the tire manufacturers could improve there product though , especially with what there charging for about 10 bucks of raw materials these days , or at least thats what i was told by a distributor a tire cost as far as raw materials go......

Well with the graphene stuff, it’s becoming so much more common everywhere, not that long ago it was over 10,000 a gram, now it’s 98 bucks and it still hasn’t taken a set in the market like it’s going to. Give it a couple years and graphene will be quite cheap. It’s easy to make. Large flake graphite you can get for about 3,000 a tonne (2200 pounds), and you can make graphene powder at home from graphite. A couple of buddies and I are going in on a tonne here and trying our luck making it. If you can make the powder, and not even the sheet graphite, you’re still able to produce a pretty large quantity of it.You just need sulfuric acid to oxidize the graphite and separate the water produced using a filter, and then apply hydrazine to pull the oxygen up. Then you reduce it down to a powder, from there you could use that to apply it many different things. So it seems like it might be nail in the coffin, but realistically it’s not as expensive as it sounds.To put it in perspective, graphene was discovered and first made by two guys using scotch tape on graphite flakes.

I,m afraid you have exceeded my pay grade , but , good luck with that.......

Graphene is that like Jethrine Bodine? https://ndnation.com/boards/showpost...=295286;d=this

LOL Noooooo! Check out some random videos on graphene used in polymers.https://m.youtube.com/watch?v=5q5dCuptXmc https://m.youtube.com/watch?v=KXvEepLSoDE http://www.thisisinsider.com/graphen...r-bands-2017-8 It won’t be long until we see it in literally everything.

[Mr.Kennedy777]

It’s expensive now, but because of how common it is, and once production methods scale up, and demand goes up, it will be pretty cheap and found in almost everything we use.

https://youtu.be/OZW3a-AvEgE Here is a link showing how much more flame resistant graphen reinforced plastic is compared to more common plastic.Here is another video showing how strong it is when mixed into plastic.https://m.youtube.com/https://youtu....?v=YXZ1gfJMtW4

as far as a DLM goes , what would be the purpose of making the plastic components , allowed to be used , stronger ? carbon fiber wheels have been around for a while , but there banned by most tracks and sanctions , so I doubt it would ever be allowed for wheels , I,m just curious as to where you think this product could , or would be allowed , to be used and the benefit ......

[Kromulous]

Very cool stuff ! Could you add it to plastic, or some foam type polymer and inject into a tube to make the tube stronger? Would be useful in roll cages, driver area per say. Also stiffening portions of the chassis.

Additive in tires would be interesting too, i doubt anyone at Hoosier would want to do anything to add life to a tire LOL...

Im not sure but think the KILLER chassis has the bars like that .

they do , there was a paraplegic guy from north alabama , named mark dowdy , that they built him a special chassis that he could get in and out of and drive , very good people , but like the rest of the small chassis builders , hard to get recognition with out a well known driver driving your stuff......

The late Jim Watson built a dlm with downbars in the late 80's...ran it at Hales Corners and maybe some open shows around the Midwest.
