I see they've failed to fit the ejector seat. amature.

I am an electronics engineer, and not a mechanical or aeronautical engineer, but I can't help but notice the intake for that engine... It seems to be just a dryer exhaust tube leading to the side. I not sure of the actual numbers involved, but I would think that while the jet probably works, it does not work "too well". As it would not get enough air into the engine to really bring it up to Mach-anything speeds.

But again, while I know exactly how the electronics and digital meters work, engines are not my specialty.

Still looks pretty damn cool though!

..If only I could afford it. Not sure that I'd have the stones to drive it tho..

I'd be a bit worried about doing a "Richard Hammond" though....

"Mind you, the idea of giving a speed camera the finger while doing Mach 0.6 round the M25 is rather appealing"

It reminds me of a story a friend of mine once told me. He was out doing a traffic survay for the police in south Wales, doing some part time work in Sixth Form. Getting bored the saw a Tornado aproching them at low altitude and dicided to point the radar gun at it. Apparently they clocked it at 400+ mph. However they think it didnt do to much good for the gun as the next car that passed them (On a narrow country lane) was clocked at 125 mph. By all accounts they didnt get another sensable reading out of it again. Sounds like a good way for the anti speed camera people to go.

... you can see ashphalt through the frame base.

There is no WAY i'd risk my foot slipping off the plate and under that.

Countdown to the first owner posting the video of its maiden flight on YouTube. I want to see this!

Maybe Richard Hammond could test this one for us?

Yeah same here. I'd just get my friend to drive it, he has no common sense. Which is why I shouldn't cause he'd probably get himself killed.

And on the intake thing, yeah I noticed that myself. It'd be pretty ugly if someone built an imitation without intakes at all. Wouldn't the driver be sucked in? I'm no aerospace genius, but I think that's what would happen.

I'm Go Karting for my stag do on saturday. Any chance of it making it to Glasgow by then!!

I can't help notice that there is a distinct lack of any basic safety equipment, such as a firewall between the jet engine and the driver/pilot.

This go-cart has 'Richard Hammond' written all over it.

That doesn't even look slightly safe

Hahaha, I wonder what the mpg or range of the kart is. Wouldn't like having to refuel every couple of laps round the track. Seems strange why the seller doesn't fire up the kart for a snap, or try to get a mph reading using a gps receiver. Sounds fishy, you gotta be mad to bid without seeing it real life first.

'doesn't even look slightly safe'.

It's lunatics like this the human species needs. Of course a large number end up wrapped round a tree of similar and die horrible deaths, but it is only through people like this that we evolve and develop new technology. If nobody ever did anything that didn't look dangerous, we'd still be riding horses. Probably not even that. When the first person decided to climb up on the back of a horse, someone undoubtedly told him he was made and it didn't look safe.

On another note, the more people who manage to kill themselves doing stupid things like this, the less strain on the state for pensions etc. and therefore the more for me!! So, please encourage more people to do lunatic things like this.

is that really a necessary feature on a jet-powered go-kart?

oh and keep it away from the producers of Top Gear, lest they get another great idea....

I'd be interested to see how it corners at speed! Might be a tad difficult to take down the thrust in time.

"Push one button to inject fuel, then push the other to ignite!"

You're pouring fuel into a jet exhaust and it needs to be ignited..?

This has 'loony' written all over it, IMO.

This is an Urban Legend, and it's been circulating for around a decade. A more extended version of the same has the jet's automatic fire control system designating the speed gun that "painted" it as a threat, and triggering an automatic retaliatory A-G strike, only thwarted by its fail-safes. (Some variations actually suggest that the missile was fired.)

See http://www.snopes.com/horrors/techno/radar.asp

Although the Snopes page dates it to 1999, I'd definitely come across the legend before that date.

Anyone claiming to have done more than 60 on the M25 must be a liar.

Hmmm... bit asymmetrical, no?

1 x large heavy battery on the right-hand side means increased momentum, so slower response to acceleration/breaking meaning that the cart should tend to the right while accelerating and to the left while breaking.

1 x air intake on the left-hand side should mean increased acceleration on the lighter side of the vehicle, exacerbating the veer.

The more power you have, the more stability you need, surely?

Being in the vicinity, I have emailed him a question, to see if I can "kick the tyres and light the fires" in our local B&Q car park. No response yet.

That should be a lark. And quite possibly my last..

"maverick lansalot"

("goose lansalot" sounds too much like an instruction...)

Throw in a robot monkey co-pilot, and you've got yourself a buyer.

Perhaps the new owner can pre-register themselves for an award?

The cart lacks even the most basic of aerodynamics to keep it on the road at speed. Also with no head support the unfortunate driver would probably break their own neck the first time they accellerated

..that I saw a programme in which Jeremy Clarkson was riding around on a jet-powered bicycle. That seemed ludicrously dangerous, but extremely fun. It also didn't look a lot safer than this, and he absolutely loved it. I want one too!

All pukka race karts are. Including the evil 250cc paddle shift monsters at the sports apex. Nearly ninety horsepower, wings, slicks and 6 speed paddle shift transmission in a package weighing about 125 kilo's with driver......Yee Ha ! Heading for the wrong side of 700 hp per ton.

As for stability, some is good. Too much means it wont corner quickly enough. True rocket surfers only need apply.

Btw you need over 200 free-fall jumps to qualify for training with a wing-suit

Then you need to have your brains removed in order to qualify to use these little starter-jets :D

I'd nearly kill to take a ride on this thing.

It's really not that much different (setup wise) from a racing cart or shifter-cart. it's almost certainly what this cart is based off of. The flooring looks about right. Your feet ride up in front of the front wheels and there is all kinds of sure-footing there.

I really doubt the thing puts out all that much power. The intake to exhaust inlet/outlet size doesn't sit well with me. I'd bet a 125cc shifter cart would be entirely more scary of a ride. - they're capable of 115mph and I've seen them having a hard time getting the rear wheels to hook up through half of that. Now that's a fun ride. You can grab one here in the US for 3 grand.

People make this type of stuff all the time out of pulse-jets and old turbochargers. They look evil and have a lot of bark, but there is not a whole lot behind them.

Another thing... racing carts don't have harnesses, head restraints or roll bars. The only head restraint is the padded collar under your helmet. You crash, you bail... like a motorcycle.

Jet engined powered vehicles (running on thrust alone) need a LOT of thrust to accelerate quickly. This thing would probably accelerate at the speed of an underpowered economy car... the difference being that power wouldn't fall off on the top end - it should keep on 'pullin' longer than a piston / drivetrain vehicle. If the intake is designed right, it would actually build power the faster it went.

I still don't see it breaking a hundred... :\

Sadly any conventional kart will beat it at speed accelration and braking, they are amazingly fast . LIke the post above, this thing would probably accelerate at the speed of an underpowered economy car. Much more fun to put a motorcycle engine on one.

"I'd bet a 125cc shifter cart would be entirely more scary of a ride. - they're capable of 115mph and I've seen them having a hard time getting the rear wheels to hook up through half of that."

Scarey? Nah!

Not quite what you mean by hooking up the rear wheels. Given that the kart kas a fixed rear axle (no diff) then you either have to slide the back (fun at 60-70) or set the chassis up so that the inside wheel lifts during a turn (much faster).

As for braking, I'm guessing that the jet kart would be identical to a shifter as a 2-stroke provides neglible engine braking - that's why shifters are fitted with front brakes too.

The kart in question looks like it is intended for oval racing so turning is less critical.

I'm the other half of the team Jetped-Boarders who was responsible for this Jetkart nad can confirm that it was pretty damn quick. The turbine is an APU from a commercial jet You can see our other 'twin jet kart' which was even quicker here: www.jetped-boarders.co.uk or have a look at Youtube shortly. You will see some footage of this Jetkart :)...watch this space.....

Starter motor.

Thrust 90~500lbs

Fuel Consumption:~12Gallons per hour Jet-A

Err yeah, PDQ is that in metric or imperial? A bit like saying 'I was in the apollo craft that visited the moon and can confirm that is a big spherical object near the earth" :)

Maybe it´s because I´m on holiday elsewhere, but the image of setting off every UK robotic tax collector at Mach 0.6 is really funny.

Of course, I don´t think I´d sell it as a vehicle...rather I´d sell it as a cure for constipation!

Just no... I mean, come off it. Do I want to get a 160+mph bike with a sub 3 second 0-60 and fantastic performance and looks that matches women's Brad Pritt fantasies?

I'm guessing, wildy mind you, that cornering is not fantastic - if it exists, pulling away from silly boy racers is hard to do at best and is more uncomfortable than the original Green Meanie. Between a Fireblade and a drag kart... Fireblade wins hands down in all but... but... fuel consumption?

Nice engineering though, if you can build that, how about going one up and trebling the size and power? Mega Kart?

...only on Nintendo
