New Motorcycle World Speed Record, 367.382 mph
An anonymous reader, apparently a member of the BUB racing team, wrote to let us know that on Thursday, their crew set the new ultimate motorcycle world speed record at 367.382 mph with the BUB Seven Streamliner at the Bonneville Salt Flats in Utah. The Seven is powered by a 3 Liter, turbocharged, 16-valve V4 engine that produces a claimed 500 hp and 400 lb-ft of torque at 8500 rpm. The pilot, Chris Carr, hit 380 mph during the run.
367.38200 mph = 591.244017 km/h
Maybe car and driver would be a better place.
At that speed, I'd agree that pilot is the correct term.
I don't even have a license. Anecdotally, it seems that techies drive less than other people, unless of course they live in someplace like silicon valley. But I'd bet there's less interest in cars and motorcycles among computer geeks than, say, mechanical engineers. Anyone what to chime in with their preferences/opinions?
You keep using that word. I do not think it means what you think it means.
What they don't mention in the article is that they strapped the driver dow nto the motorcycle and dropped them both from a really tall building...

Apparently, the controls were taken from an F-4 fighter jet. But if you look at some of the pictures underneath the shell it looks slightly more motorcycle-like.
Funny may not give karma, but +5 Informative never made anyone snort coffee out their nose.
To quote the Oxford English Dictionary, which isn't always definitive but I think in this case captures the common meaning well enough, a motorcycle is:
The vehicle linked does not at all "resemble a bicycle", at least as commonly defined (enclosed two-wheel vehicles are not usually considered "bicycles").

What the article doesn't tell you is that the motorbike was running Linux and the driver was thinking about the best car analogy while he was driving.

I need a car analogy before I can understand this.
As a biker with a long graying beard, lemme point out that whatever that thing on the picture is, it damn sure ain't a motorcycle.
My wife says it's boring because it wasn't done by three guys in Hamtramck who bolted a V8 onto a Harley and made a fairing out of oil drums.
I find it interesting because it is about engineering. "IndyCars", on the other hand, are boring. All the cars are identical so it's just about the drivers. Who cares about the drivers?

Kudos to the driver and the team, but that thing is a motorcycle in spirit only.
Can the definition of a motorcycle include an enclosed cockpit?

If the /record/ speed is 367.382mph, but during the run the driver reached 380mph, I could imagine he must have been very uncomfortable smashed against the windshield of his "motorcycle".
'Every story, if continued long enough, ends in death.' --Ernest Hemingway
I found this part particularly inspiring:
"The shape of 'Seven' is based on that of a Coho Salmon. While watching TV Denis noticed the fluid dynamics of the salmon through water. Knowing that water is more dense than air- Denis figured the shape would work very well at Bonneville. Wind Tunnel testing of Seven at the A2WT proved 'Seven' to have the lowest CoD of any streamliner- 0.09. "
There's nothing more beautiful than taking the best designs from nature and applying them to our own.

This all boils down to how you define geek.
I'm an automotive mechanic. My friends and family would also consider me to be a big geek. I fix their computers (yes yes, cars too), I build my own (computers, I haven't built a car from scratch... yet!). I love gadgets and hacking stuff together, and I have an abnormal interest in technology related politics (my girlfriend calls me paranoid). So to the general public, i'm a geek.
Among the Slashdot crowd, I don't have quite the same geek credentials. I don't use any flavour of Linux (besides the occasional liveCD like Backtrack) because my PC is a gaming rig first and foremost. I'm not a sys admin or a programmer. The last thing I "programmed" was fifteen years ago and written in BASIC. I don't run a website, and the extent of my HTML knowledge is frames and tables. I hate math and I don't get off on exciting new prime numbers or subatomic particles. Oh, and i've only played D&D like, twice. It was fun but time consuming. Am I still a geek?
My personal opinion is that geek has moved far beyond the 1980's definition of pocket protectors, glasses, and a calculator. Geeks come in all flavours now, from classical computing and math geeks all the way into sports and automotive geeks. The microprocessor really has changed the way we see the modern world, in virtually every way. A geek is now anyone who shares both a passion for a subject and the thirst for related knowledge, no matter what that subject may be.
The geek shall inherit the Earth. :)
The story reminded me the Jato Rocket Car urban legend. The speed reached there is even lower than the one that got that motorcycle.
A Google image search for 'bicycle speed record' shows otherwise.
The flat land speed bikes in particular.
John McAfee 'It was like that time I hired that Bangkok prostitute; to do my taxes, while I fucked my accountant'
Many of us have friends who are interested in motorsports and the tricking-out of vehicles, and shop-talk is necessary to communicate with them.
Pardon the stereotype, but getting in tough with one's inner neanderthal is required when you're out in the desert driving metal boxes at unsafe velocities and sending search parties to other camps for loud slaps on the back before grilling fat steaks and singing war songs. Gasoline smells GOOOOOOOD.
Most importantly - know, befriend, or become an auto mechanic. They're interesting company and they'll work for parts and a 12-pack.
But can it do the Kessell run in 5 parsecs? That's what I thought.
IMO the first linked article was not very interesting. To get to the interesting stuff, you have to go to the second linked article, then click through to the links from there. The pictures of how they fabricated the engine block are really cool. I was surprised there wasn't more info about the tires. My understanding was that tires were the main limiting factor in land speed records -- or maybe that's only for cars. Tires tend to fly apart when rotated that fast. I would assume that at these speeds they get incredible gyroscopic stability, so I guess you don't have to worry about tipping over. They have to run the course in both directions without messing with the engine, which apparently is quite a challenge. I wasn't clear on what's involved in turning around to come back. The bike has both brakes and parachutes. Does the driver actually brake and do a steered u-turn at low speed, or do they use parachutes, then pick the thing back up and turn it around by hand?
Find free books.
When doing a LSR run at Bonneville you have something like a half hour between runs. They let you refuel and check the vehicle over between runs for safety reasons. If you have a problem and can't make it back to the starting line on time you're toast. You one-way run doesn't count for anything.
"while democracy seeks equality in liberty, socialism seeks equality in restraint and servitude." de Tocqueville
They'll probably turn it by hand, most land speed vehicles have a tiny, tiny amount of steering angle to keep a sudden twitch on the driver's part from turning into a two mile long barrel roll.
I am a computer geek at work. After hours I like to wrench on my WRX, or my bike, or the classic boat I had for a few years... Something different from the job. Yet I still find all the information for my vehicular diversions on the internet... Curses, foiled again!
Well, spec series are about the driver's skill, which is pretty much what sports are about - the skill of the players.
However, it's much more fun to go out, get a cheap Miata, or if FWD is more your thing, a cheap Civic or Golf or something, and autocross it, than to sit around watching a spec series, IMO. Then, it's about honing your own skill, not watching others. (But, you can learn techniques from watching how they handle situations, so watching them can still be educational.)
Of course, the American Le Mans Series is ridiculously fun as a spectator series. Multiple classes of cars of varying power outputs, weights, visibility, handling, and (often) driver experience all out on the track at once, and the drivers and cars are surprisingly accessible. Oh, and it's about as far from a spec series as it gets - you can easily have a big heavy (ok, 900 kg/1980 lb, but still) V12 diesel car and a light (825 kg/1820 lb) 4-cylinder turbocharged gas car fighting for the lead of the entire race, the whole way, meanwhile weaving their way through traffic caused by big slow production-based cars.
I don't even have a license. Anecdotally, it seems that techies drive less than other people, unless of course they live in someplace like silicon valley. But I'd bet there's less interest in cars and motorcycles among computer geeks than, say, mechanical engineers. Anyone what to chime in with their preferences/opinions?
Odd. In my (similarly anecdotal) experience, there seems to be a disproportionate intersection of Computer Geeks and Motorcyclists (the latter set the union of Riders and Enthusiasts).
My personal opinion is that geek has moved far beyond the 1980's definition of pocket protectors, glasses, and a calculator. Geeks come in all flavours now, from classical computing and math geeks all the way into sports and automotive geeks.
My personal opinion is that geek still means carnival folk who bite the heads off chickens. "Nerd" or "boffin" are my preferred terms for people who are excited or obsessive about technical things. "Geek" has too many connotations of falsity, they remind me of the web-bubble MBA types who wouldn't like being called nerds, and think that "geek" has cooler connotations. But there's nothing cool about biting the heads off chickens.
... and then they built the supercollider.
One day, I will drive the Paris/Dakkar!

That wouldn't work: there's no cycle in a rocket motor (except the turbo-pumps in a liquid rocket) It's open circuit.

There's reason enough to apologize and I do think he meant it. Piloting a motorbike at those speeds is a great feat, it's rude to undermine the undertaking and I believe the OP "feels" that. I'm not motorhead at *all*, I hate working on cars, to me it's like all of the bad stuff that gets engineered into computers, lack of standards (metric vs english, everywhere), lack of documentation, someone always trying to upsell something, the use of jargon to displace the customer, etc. But I felt like defending the motorbike definition, because pedantically, it qualifies for the motorbike land speed and most of all it is the last land-speed that doesn't incorporate jet engines.

That isn't even about drivers. It's about money. Useful stuff, but who wants to watch it?
Of course, now that they have taken to deliberately crashing cars maybe it will become interesting again, in a morbid, hockey-like way.

Damn straight! I'm a former glasses-wearing high school computer nerd who has variously been a programmer, electrician, locksmith, auto mechanic, communications systems technician, process control engineer, and US Army Human Intelligence Collector/Infantryman over the last 20-odd years. I think "nerd/geek" is a much bigger tent than people realize.

Hmm. Even odder. In my experience there seems to be a disproportionate intersection of the homosexual bondage world and users of slackware, who seem to have their manhood wrapped up in their operating system.
Nah, autocross is boring. You wait a whole bunch of time to do one lap around a 50 second course in a mall parking lot dotted with cones.
Go to a track day, on a real road track, and get so much driving time that you'll be sick of it by the late afternoon.
You could also buy a shifter cart and drive all day for much cheaper and probably have an even bigger blast.
But friends don't let friends autocross.
And since when have bikes needed to be open to be considered true bikes?
This kind of speed on a motorcycle involves deep understanding of motorcycles as well as high speed behaviors. There are lots of ways in which anyone can get high powered engines sufficient for that kind of speed. But making it all come together into a machine that doesn't fall apart or become impossible to control requires serious mechanical and design talent.
In the 1950 era any street bike that reached 100 mph put its rider at great risk. I can recall bikes at 105 mph that felt like sitting on a razor blade in a hurricane. It was just grit your teeth and hope to stay alive. Now street bikes can often hit 200 mph with some elements of safety.
I don't recall any bicycles with full fairings on them. Does that mean supersports aren't motorcycles?
Think of the body as a really really big fairing, that encompasses the rider.

There's nothing more beautiful than thinking "That's silly, water and air are completely different mediums" and then reading it worked great :)
Yeah. Would you choose a neurosurgeon who pokes around people's brains in his spare time? I wouldn't.
Reminds me of a guy who died last year at this time on the Bonneville Salt Flats attempting the same thing. Can you imagine flying off a motorcycle at 239 MPH? Insanity.
Flying off, no problem. The road rash when you hit the ground, ouch! The fact that you're being scraped over salt, owie owie owie!
But does it... run... linux... *head explodes*
Ha. Care to back that up with anything?
Mechanicals have to know how to use software, but it sure hasn't replaced us.
I like how Bryan Harley referred to the rider as the "pilot".
The cost of that cleanup, of course, will be borne by taxpayers, not industry.
And there is really no shame in rocket cars
In my humble experience, (~125 MPH over Altamont Pass towards Livermore), when the winds are kicking up, the best policy is to go WOT. The gyroscopic effect of the wheels is increased, and the ride is much less scary than at 55.
The cost of that cleanup, of course, will be borne by taxpayers, not industry.
Think of it as "Star Wars/Pod Racer" IRL.

"Really, car racing is boring as fuck to watch."
That has always been my attitude with sports in general. The only time I ever got excited over sports was in high school, then (much) later when my sons played sports. I've only RARELY watched an entire Super Bowl, NEVER watched an entire World Series, and nothing else even comes close. Wait - to be fair, I have a passing interest in track and field, and I've watched Olympic events pretty attentively. My career as a spectator pretty much ends there. I'd rather read a book, or argue with dummies about politics or something.

I've seen fairings for racing motorcycles with leg-shaped cut-outs on the sides due to class restrictions.

Does it get more MPG than the Aptera? Can it run on wind power? Electric? Can it run macos? Can it reduce traffic? Pollution? Well, I guess combustion-engine-generated raw power is waaay obsolete. Perhaps for aircraft or boats. If it were a wige small craft it would be nice.

This has little to do with understanding motorcycles. It's about balancing a huge speed machine on two wheels; I doubt it bears any but the most superficial resemblance to regular motorcycles. When you make such a stretch to call it a motorcycle you might as well just abandon the wheels altogether and have a rocket powered sled. Or just fly around on a rocket dragging a long cable behind you so you can technically call it a land speed record.
I actually consider the vehicle in question a motorbike. I just don't think people should preemptively apologize for having opinions. It annoys me that people are so afraid to stand up for what they believe that they apologize just for saying it. Pet peeve, I guess. As to the record itself, it's very impressive in any land vehicle of any means of propulsion.
At those speeds, air is pretty dense.
Yeah, that's like "popularity nerd" or "football nerd" or "cheerleader nerd". Now, I have no qualms letting the guys who engineered this thing be considered nerds, but your average Bud-guzzling-jacked-up-F250-driving-NASCAR fan is not a nerd, and I feel offended that such a person who never likely felt the negative social impact of nerdiness would latch on to the term.
What changed under Obama? Nothing Good
IMO, what you're describing isn't a geek. It's a man - you know, in the traditional sense. Fifty, 60 years ago, it was commonplace for men to fix their own things, and to make new things. It was also expected. Back before that, a man who did not was known as being useless - because there was precious little "general handyman" workers back then, as there are now. It's only been recently that people have gotten away from fixing things themselves.
I think a "geek" is typically seen as not someone who's in the know where others aren't; s/he is the person who is seen as "smarter" than everyone else in one or more domains: not only a competent tradesman but also a statesman of ideas, and someone who can figure things out due to their natural curiosity. A Renaissance Man, if you will. Pocket protectors or no, they often suffer similar social stigmas, though obviously there is going to be a varying degree of social competence. Due to social stratification in the past 30 years, there are certain segments of society which more readily accept (and embrace) the "geek", but there are still a lot of people out there who despise them.

A drag coefficient of 0.08 is amazingly awesome. For example, it's equal third place in the wikipedia concept car drag coefficient list (first is 0.07). And the frontal area is next to nothing, so the CD*A figure is going to be excellent too. Put a 100cc engine in it with appropriately tall gearing and it would most likely get better than 0.5 litres per 100km. Consider that the PAC-II has a Cd of 0.075 and gets 0.017l/100km equivalent.

Find a job you like and you will never work a day in your life.
False. The density of air does not change with speed. What you may be trying to refer to is called the Reynolds number, a dimensionless quantity that relates fluid velocity with viscosity and characteristic length-scale. This is what allows the Mythbusters to make their own wind tunnel using water for the "Tail-gate Up or Down" episode. By setting the velocity of the water to compensate for the increased viscosity compared to air, they can get pretty close to simulating highway speeds for their model truck (characteristic length scales having been taken into consideration as well).
The only thing that would be pretty dense at those speeds would be this anonymous coward.

You're not autocrossing with the right club, I can get 10-12 runs in one day with the club I run with.
Also, I used autocross specifically because you can go out with your daily driver, have fun, and then go home without much wear and tear on your car.
Track days, you pretty much have to be prepared to buy a replacement car, and even if you don't, buy new brakes and tires.
Karting could be cheap and fun if you rent a kart for a day, though.
The way they cast the engine block surprised me.
Using a tradition pattern to make a sand mold is fraught with problems. The main problem is sand being washed into the molten metal as it is poured into the runners. Any defects in an engine block, which is put through a lot of stress, and you could be looking at explosive results.
Rover - remember them? - were the first to use a type injection molding for engine blocks on their infamous K6. Metal is injected at the bottom of the casting to improve flow, cooling, and of course remove the sand washing problem. I believe all blocks are made this way now.

A 3 liter engine making 500HP is not under a terrible amount of stress. My streetbike makes 200HP at the rear wheel and diplaces 1.4 liters. This thing is only making 16% more power per liter than mine and I run on pump gas and have put 20 thousand trouble-free miles it.
If I were on the team for the motorcycle, I would have recommended a turbo Hayabusa motor. You can easily get 500 or 600 horsepower without any risk of engine problems and fit it in a much smaller footprint than their custom engine.

Random Thoughts From A Diseased Mind (Not For Dummies)
A properly designed sand casting is defect free with proper quality control. Most of the sand that is washed ends up in the gates and sprue. Most of the surfaces (somewhat rough in a sand casting) are going to be shot peened and machined smooth anyway...
A foundry that produces sand inclusions in their castings without any quality control will not stay in business very long at all.

But why break pattern? An inline four would be smaller and machanically simpler than a V-4. Also, if you need a small engine and your class has essentially no rules, then not running a turbo sounds like a bone-headed move to me. The turbo Hayabusa was offered as an example of how it could be done for $25,000 by any idiot off the street. But if you want to fab it yourself, 1.5 liters and a 16-valve, short stroke, turbo inline four is still the tried and true way to get 500HP in a small package.
