You Might Be Cool, But You’re Not Gas Turbine Motorcycle Cool

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.

  1. To pile on to JRDM’s comment, this engine is a turboshaft engine, because the power is directed to a shaft which drives something else. Other applications for turboshaft engines include helicopters and propeller-driven aircraft. Other forms of gas tubine engine which are not turboshaft engines include turbojet and turbofan engines, both of which use the exhaust stream itself to propel the vehicle.

    1. Pretty amazing. That thing seems significantly faster than my liter bike; which easily runs 200+mph 1/4’s. I want one!

      Contrary to the the original post, i don’t see anything Harley about it.

  2. As one of the administrators of the JATO forum, I have to tell you we are very fortunate to have Anders onboard and we are very thankful for his documenting this build.

  3. Looking at the Wikipedia page for gas turbines, it looks like the first documented gas turbine able to produce useful power was built in 1903. Then the tech would get to where it was propelling vehicles in the next few decades through the efforts of governments and companies with teams of scientists and engineers. Now it’s moved to this vehicle today.
    It’s awesome how the tech has progressed to where it is ‘accessible’ like this.

  4. “…while a true jet dumps all the energy into the front bumper of the car behind ”

    No – that is not how jet engines work. Jet engines primarily use Newton’s third law of motion, ejecting mass at a velocity in one direction to cause the mass of the engine and it’s attached vehicle to be subjected to a force in the opposite direction. Some energy would also be transferred to a following vehicle, but certainly not all of it, otherwise the engine itself would not be propelled forwards.

      1. Not really. Just trying to ensure that the “myth” that jet engines work by pushing against an object doesn’t gain any more traction than it already has. (Pun not intentional)

  5. The video of the 1st start scares the crap out of me. No hearing / eye protection… and it looks like what’s known as a “slow start” leading into a “hung start.” A lot of the white vapor you see is unburnt fuel — the engine wasn’t spinning fast enough to handle a light-off at such a low N1. I’ve seen slow starts like this end spectacularly (fireball)… or in a somewhat boring, but engine destroying hung start that massively over-temps.
