NEXTECH Mod sled

1200 in crate.jpg

Well here it is the donor sled for our mod project.
The goal for this project is to build a 4 stroke jackson hole hill climb sled that Carl Kuster will pilot.
This type of sled must be very agile, handle big bumps and of course be realy fast. The real challange with making this happen is it must be light and of course very strong. To acheieve all these goals this sled has the the most exotic parts and many custom peices along with help from some of the most knowlagable forward thinkers in the busness.

Chopping apart a 1 of 2 factory prototype?

Tons of weight lost already.

Sand and clearcoat inner tunnel so snow just falls off.

The running boards are one of a kind. Weighing just 1.5 lb each these pure carbon boards are CNC cut for a interlock fit then glued and riveted then wraped with a carbon tow. Sanded and clear-coated. Strongest board ever built and the lightest.running board machining.jpg

Just needs to be finish tied int the tunnel at angle so you cannot fall off and have a reference, but this we will do later after testing.

under 60 lb for tunnel boards bulk head and coolers. this is with some of our own chassis reinforcment as security because this thing is going to get beat on.
 
Wow, that is really cool. But what's the deal with the prototype? Why not just get the production sled? Isn't that available as production?
 
It looks pretty cool, but I would not trust the a-arms to take the hits. I have seen some carbon fibre suspension parts break pretty easy. From what I have seen carbon fibre is torsionally strong but will not take a sudden impact very well. I think the formula one guys have the cf program figured out pretty well and they use it where they can. BTW have you seen a F1 car hit a wall...it kind of like an explosion.

i wouldnt trust carbon fiber a-arms or suspention at jackson hole if my life depended on it

The a-arms have been out for years and tested by some top racers and many customers.This last fall we had a few issues with the initial release of the xp style and can admit it. This was partialy due to being over confident from the proven rev style. Changes have been made and lots of testing in house and in the feild diving the front end into the largest holes on big jumps. We have a longer and more diverse testing pollicy now before any product release, We always take care of our customers.

driving a steel and aluminum car into a wall results in complete destruction also.

here are some more pics. The weight with all fluids and 11 liters of fuel is 480 lb and at 200plus hp is scary fast. We are proud for you have a look at our project, but the mods are no were near done. If anybody is interested i will post pics as more things get improved.

So the sled is done, did kuster take a run at Jackson?

Unfortunatly no carl Got the first ride at altitude 1 week before jackson. The clutching and motor needed some tuning for faster response and back shift. Also need more than 1 weekend of abuse testing on all components. This year there was only 1 foot of snow on the hill so we elected to skip this year and be really prepared for next.

most of all the carbon parts you see in the wrecks are bodywork, wings, and parts built to break first. The carbon fiber parts on a F1 suspension do not break unless they intend for them to. They have weak parts design to break first like the rod ends or the billet parts the suspension connects to. Hence the reason you see wheel tethers now. F1 has strict safety standards with a lot of parts made to break easily to absorb the impact.

In a A-arm design the lower arm is in tension and the upper is in compression. Carbon fiber is extremely strong in this application. F1 carbon suspension withstand huge amounts of forces. When designed correctly, I would totally trust a carbon suspension on a sled. For instance, you should be able to huck off a 100ft cliff onto a flat landing and the arms would still be good (maybe not your knees or back). However, rapping the arms around a tree might be a different story. For this reason you don't see many carbon bumpers.

Anyhow, I like seeing sled companies really trying to use it but only when used correctly.

Speaking of torsion I am surprised to see that no one has built a carbon jackshaft or driveshaft, that should shed some good rotating mass. hmm..even a carbon brake rotor. It would sure be fun to have $100k+ to build a sled with.

Here are a few more on lake. First 2 plans for the summer is to build water to air intercooler for less weight, better mass centralization and far less intake charge volume.
Also going to build a 1 peice titanium riser post combo with real carbon bars and clamp.

With filiment winding tech the drive shafts would be awsome and this is something we have considered. Also looked heavily int the rotors and these are possible and far more economic with new ceramic matrixes.
It is a matter of time and funds to develop vs limited demand but i am confident in the future we will see these types of tech on even factory sleds.
 
can you build a nytro motor with the stuff? :face-icon-small-hap

Cool project! It is amazing how far this technology has come. Can this stuff be recycled at all? Like ground up and reused or something?

Anything can be built. There are motors in race cars that have carbon cases and all f1 cars have carbon trany cases. I will look to see if can find the artical about the transmisions for it is cool. In the artical it explains how they only lasted 1-2 races when made of magniesium and swiching to carbon they lost weight and now get 1-2 seasons. Of course these are not cheap peices.

As far as recycling there is no great method or use that I now of.
 
so when these carbon sleds take a tumble or a hit how do you go about fixing em???
