Unlimited Class Karting - What is Possible?

Where do you put the driver? :joy:

Oh wait a sec… I see it now! Left of the engines.

Here’s a rear shot of Nevil Algie’s carbon creation…Algie Composites made it:

He also made an interesting superkart for Daytona Unlimited competition, which was what I set out to find. I’d like to copy and refine it.

I’ll copy it here when I locate it. Had a raised nose design.

I honestly don’t even know what to say to you guys at this point. Can I drive all of them!?!?

Absolutely ballistic weapons grade stuff. They run all these at Daytona kart event? I’m in California but might have to make a trip at some point for that. Sounds amazing.

More goodness in Nevils kart:

More still, and the original superkart I was searching for:

That’s super cool looking. :heart::heart::heart:

REgrettably, the carbon flyer didn’t handle well… I’m guessing it was too rigid torsionally. But it was reportedly fast in a straight line…

As for the Superkart, I think it had teething issues, and was never fully developed. I plan to make something similar. Will be a pet project for a while. Once it’s started, I’ll make a thread.

Huh…carbon fiber doesn’t flex enough for the chassis to work like a normal kart, is that correct?

Carbon can be as stiff or flexible as needed – it’s the geometry that determines how it resists bending. So I’m guessing that this creation doesn’t mimic what the waist of a “normal” kart does. The Swiss Hutless “dynamic bend” was the start of a new era, and I haven’t seen anything since improve upon it in revolutionary fashion. The improvements since 1990 seem to be mostly incremental. And as manufacturers consolidate, innovation and risk taking seem to diminish as well…pity.

Long live the experimenters! They may find what doesn’t work more often, but only they will know the satisfaction of finding what works BETTER…

That thing looks the part!

Has anyone been able to fit a jetski engine to a kart?

Someone was telling me there jetski had a rotax 800 2 stroke putting out around 150bhp and rebuilt it every 60hrs or so.

Although no gearbox so not sure how that could work

Autocross guys have used snowmobile engines in the A-modified class to produce around 250-300hp. Not sure about the physical size compared to a jetski engine. Good idea.

Tularis made a motorcycle with a snowmobile engine.

I really like where this thread has gone.

200-300hp kart sounds possible. As does a good amount of downforce. Laying down. With a gear box. Where is this kart…

It’s a packaging issue. The driver with…hardware…big enough to drive this has a hard time laying down in the kart.

As is the case with these things. How effective would it be to scale up a chassis and other components to get the right fit? I’d think in the long history of the sport someone may have tried that, but I can imagine there would be many unforeseen issues.

One of the best parts of the sport. Only limited by your imagination and time.
