Completely agreed. Either the Beetle is fake, or it works very poorly. Little to no airflow to feed the jet engine (if the engine can even run, it would be running nowhere near optimum performance), and a horsepower rating for an engine converted to produce thrust (it now produces 0hp since there is no more shaft). The guy is obviously not a PhD in Mechanical Engineering though. Or if he is, Stanford must be a really crappy Engineering school, producing Engineers wasting perfectly fine helicopter engines for reasons like this.TheWizardI call bs on the jet powered VW Beetle.
A jet engine like that, especially with an afterburner, needs massive amounts of air flow. If that wasn't enough, the compressor and the turbine are completely exposed to the air, therefore making them completely useless. A compressor needs to be encased, else it won't compress anything.
The nozzle, also, looks like it's not sturdy enough and it's even slit open down at the bottom.
That "jet engine" is just for "shows" and all it does is putting flames out the back.
Also, notice how, in all the shots where the "engine" is running, the car is completely stationary. Jet engines put out thousands of pounds of thrust, expecially when the afterburner is running. No way, if that was real, the brakes could keep the car from moving. They may be able to lock the wheels, but the car would still be sliding forward.
Sorry, dude. Your ME degree at Stanford is obviously total bs. Go play with real cars...

Liar. Someone has already built a jet powered beetle. It appeared at this VW festival in 2004. And unlike the one posted in this thread, it's a convertible, so there would at least be some airflow for the jet engine once the car gets to a certain speed. And the cabin would not become a funnel for the intake (as would be the case with the PhD's Beetle).Supposed PhD Guy“The car was built because I wanted the wildest street-legal ride possible. With this project, I was able to use my engineering skills (I have a PhD in Mechanical Engineering from Stanford University) to design the car without the distraction of how other people have done it in the past - because no one has.”
And this car is a much more intense street legal car. It also at least serves a purpose.
