Riding rockets and jets around the frozen wastes of Sweden

An attentive reader tipped us off to the guys at Mobacken Racing (translation), a group of Swedes dedicated to the art and craft of putting jet and rocket engines on go karts and snowmobiles.

One of the simpler builds is a pulse jet sled. Pulse jets are extremely simple devices – just a few stainless steel tubes welded together and started with a leaf blower. The simplicity of a pulse jet lends itself to running very hot and very loudly; the perfect engine for putting the fear of a Norse god into the hearts of racing opponents.

Pulse jets are a bit too simple for [Johansson], so he dedicates his time towards building a jet turbine engine. Right now it’s only on a test stand, but there’s still an awesome amount of thrust coming out of that thing, as shown in the video after the break.

In our humble opinion, the most interesting build is the 1000 Newton liquid fuel rocket engine. The liquid-cooled engine guzzles NOX and methanol, and bears a striking resemblance to liquid fuel engines we’ve seen before. Sadly, there are no videos of this engine being fired (only pics of it strapped to a go-kart), but sit back and watch a couple other hilariously overpowered engines disturbing a tranquil sylvan winter after the break.

Edit: [Linus Nilsson] wrote in to tell us while the guys at Mobacken Racing are good friends, [Linus], his brother, and third guy (his words) are responsible for the pulse jet sled. The pulse jet is actually ‘valved’ and not as simple as a few stainless steel tubes. The pulse jet isn’t started by a leaf blower, either, but a four kilowatt fan. [Linus]‘ crew call themselves Svarthalet racing, and you can check out the Google translation here.

Tailgating this car carries a heavy penalty

This hack seems simple enough:

  1. 1. Open hatchback
  2. 2. Insert jet engine
  3. 3. Profit

Actually, the guy who added a jet engine to a VW Beetle has a PhD in Mechanical Engineering from Stanford. He claims this is street legal, and even has a snapshot of the police trying to figure out what to charge him with after stopping him on the road. There’s plenty of details and we’re not questioning [Ron Patrick's] competence, but having the intake for the turbine inside the cab of the vehicle seems a bit insane. He remarks that “it’s a little windy but not unbearable”… yeah.

One the same page you’ll find his dual-jet modified scooter. The starting cost there is considerably less, especially if you build your own ram jets.

Sukhoi Su-27 Jet build throws down

This no model, but a fully functioning RC jet. The Sukhoi Su-27 was the Soviet Union’s counterpart of the F15 and this 1/6.5 scaled version measures eleven feet long and is fully controllable. As if the 80-page build log wasn’t enough, the flight video after the break is nothing short of jaw-dropping. The test flights end in smooth landings but with all the time that went into the project that’s got to be nerve-wracking.

Jet powered hijinks

This jet powered carousel is brought to you by the Madagascar Institute. They convene, or collide, to create large scale art, sculptures, and rides. This one seems to fit the last definition. The two gentlemen are strapped to a jet powered carousel. It actually looks pretty fun, but we would have been needing some fresh shorts after the jet bursts into flames near the end. He didn’t seem too concerned, he wasn’t screaming and flailing his arms at least.
