For the last four and a half years, [Anders] has been working on a motorcycle project. This isn’t just any old Harley covering a garage floor with oil – this is a gas turbine powered bike built to break the land speed record at Bonneville.
The engine inside [Anders]’s bike is a gas turbine – not a jet engine. There’s really not much difference in the design of these engines, except for the fact that a turbine dumps all the energy into a drive shaft, while a true jet dumps all the energy into the front bumper of the car behind this bike. [Anders] built this engine from scratch, documented entirely on a massive 120 page forum thread. Just about everything is machined by him, bolted to a frame designed and fabricated by him, and with any luck, will break the land speed record of 349 km/h (216mph) on the salt flats of Bonneville.
As with all jet and turbine builds, this one must be heard to be believed. There are a few videos of the turbine in action below, including one where the turbine drives the rear wheel.

Back in 1996, a group of engineering students at McMaster University set out to build a fully functional hot tub housed in a working car. They chopped up an abandoned 1982 Chevy Malibu and converted it into The Carpool.
That group of students graduated, and began work on the Carpool DeVille. Six years later, they’re ready to take it to Bonneville Salt Flats to claim the title of “world’s fastest hot tub.”
There has been some substantial modifications to the vehicle to make the Carpool a reality. A custom fibreglass tub was built to drop into the passenger compartment, and heat exchangers were added to the stock engine system to heat the water. The plumbing and pumps for the tub reside in the truck, while the original V8 engine is up in the front. A custom air suspension system allows them to carry the massive volume of water. There’s even a marine throttle to control gas and brake from the driver’s seat in the tub.
The folks behind the Carpool DeVille ran a Kickstarter to fund their race costs. The campaign is over, but you can still check out the story and pictures of the conversion. Since it was a successful campaign, we’re looking forward to seeing this custom vehicle out on the salt flats.
[Donhou] had a dream. To create a road bike capable of reaching 100mph (160km/h).
He damn well near did it too. The goal of this project wasn’t to set a land speed record, but more of an experiment in design, and building a really fast bike that still looks like a bicycle. In case you’re wondering though, the land speed record is currently set at 167mph by [Fred Rompelberg] who was drafting behind a dragster on the Salt Flats of Bonneville.
The bike features custom everything; a welded lightweight frame using Columbus Max tubing (to help with speed wobbles), super low handlebars for aerodynamics, and a massive 104 tooth chainring which almost scrapes the ground as you pedal. Even the rims and tires are unique — regular bicycle wheels just aren’t designed to go that fast.
We aren’t even bike nuts, but we thoroughly enjoyed the awesome 9-minute documentary on this project. Check it out after the break.
