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.

    Not to be funny, but this has been around for quite a while, I can’t believe you haven’t seen it!

  • The DON says:

    The Beetle-mobile

  • Dan Fruzzetti says:

    seems to me that DRIVING THAT ON A STREET would also carry a heavy penalty

  • caps says:

    ramjets would not operate well at all at the speeds a VW Beetle would go.

  • KittyKat says:

    @Dan Did you miss the part that said Street legal? or just ignore it?

  • Eddie says:

    Don’t forget to roll down the windows.

  • Cynyr says:

    @Dan
    If you turn it on there, sure, otherwise why would it be different that hanging some wood out the back.

  • medix says:

    Ever see the one built inside a minivan? (not this guy). You had to keep the side doors open, or it would suck the windows in.

  • hpux735 says:

    It seems like a beetle is about the strangest choice for a hack like this. A 80′s muscle car would be more fitting, I think.

  • AridTag says:

    Want a video of it in action!

  • Jason says:

    @hpux735

    They are useless for anything else

  • Wolf says:

    Greatest. Hack. Ever.

  • Tommy Faze says:

    I am thoroughly unfazed, while it’s a hack the working on the beetle fitting that engine was amateurish, and the actual metal works for the body rather raw. Same goes with the throttle installation and instrumentation.

    I rate this a C-

  • zool says:

    yeah 3+ years old or so

    i like the jet powered scooter on his page though, hadn’t seen that one before

  • Jack says:

    I think you meant to say “On the same page” not “One the same page”

  • acoq says:

    Waiting for NFS: Jet propulsion

  • Alex M. says:

    @medix: This is a jet engine, the minivan is powered by a helicopter turbine that drives the rear wheels (gas engine drives the front wheels). This provides thrust while the minivan’s turbine doesn’t.

    Still cool though.

  • asdasd says:

    ramjets cannot work without an engine:
    they need a LOT of air to work so it’s usable only on planes(also it’s an old and unused concept).

    It’s better to have a pulse-jet that cost almost nothing and it’s evene simplyer!

  • bfsgbvsd says:

    Ooooooooooooooooooooooooooooooooooooooold

  • Hirudinea says:

    @hpux735

    Nah, he should have used a Smart Car!

  • Jason says:

    @Tommy Faze

    so wheres your jet powered car? since you have done so many and all.

  • xorpunk says:

    How is this even remotely street legal? It literally incinerates the vehicles behind it..

  • cmholm says:

    Back in the early ’90′s, an older Honda Civic passed me on the Simi Valley freeway, headed towards Moorpark College. It included an air scoop on the roof, linked to a duct dropping behind the front seats, and a CA license plate was cut in two, each half hinged to swing open and expose a large diameter tailpipe. After the car passed, the plate halves swung shut.

    Unfortunately, I had the radio on too loud to notice if there had been a turbine sound, and I didn’t opt to be late to work and follow the car to its destination for a better look/explanation.

  • biozz says:

    did it really have to be a beetle? … the joke among cars? XD

  • Erwin says:

    “has a PhD in Mechanical Engineering from Stanford”
    So what? his still a dumb4ss

    What to charge him with maybe killing the driver of the car behind him. Also that car is a piece of …

  • Draco says:

    So that is where our research dollars go!!

  • 60's stuff says:

    “did it really have to be a beetle? … the joke among cars? XD”
    Well, yeah, for the colors/flashbacks.

  • Taylor Alexander says:

    Guys, I think part of the reason he chose a Beetle was for exactly the reason that you’re all saying he shouldn’t have… Because its totally the wrong car… and that makes it funny!

    Get a sense of humor people!

  • vonskippy says:

    “has a PhD in Mechanical Engineering from Stanford”

    Unless he spent more time in the Crown Quad then Building 560, it doesn’t make him a law expert.

    No WAY is that street legal.

    Lets see him site the law that allows that on the road.

  • pogyhauler says:

    ——————Yawn—————-

    We’ve seen rockets/turbojets/ramjets/pulsejets
    of any size shape or description attached to anything that moves. Including a couch on casters.

    Nobody remembers Mad Max?

    The notion was already old and boring before ‘Hooper’. The movie sucked but at least they had the grace to use a Camaro.

    I guess even Stanford Grads can have more money than sense.

  • bob says:

    Nice work if not new nor practical.

    He’s lucky he wasn’t stopped by “Ponch” & “Jon”.
    Those CHiPs guys kick ass.

  • zing says:

    @vonskippy

    It is street legal, but only as long as he doesn’t turn on the jet while on public property. It still has a regular gas engine.

    They could get him with a noise citation, though.

  • Josh says:

    Wow! I remember seeing (hearing!) this in person a few years ago. The owner is a unique (nice) individual.

  • JB says:

    Great hack. Nice to keep tailgaters at the right distance :P

    If the picture is 1/20th the fireball, I want to see a video (zoomed out). Cool stuff. It is nice to have money.

  • Zac says:

    Not Street legal in the US.

    US DOT requires a little thing called a “bumper” capable of absorbing low speed (2 MPH) impact damage on passenger vehicles. I don’t see a bumper on the end of that jet.

    He gets away with it because California doesn’t have a comprehensive safety inspection (only emissions).

    Or if he classifies it as a non “passenger vehicle,” that doesn’t have to meet bumper standards. Maybe if he carries around a loaf, he can try and pretend it’s a bread truck.

  • nubie says:

    I am guessing that “Tommy Faze” hasn’t had a look at the extensive aluminum frame attached to the body underneath the bumper skin.

    The metalwork inside (did you mean bodywork? That is likely polyurathane), is pristine.

    This is pretty old, I have seen it in Mags and David Letterman had it in a segment for his show (he said the visibility was “10 miles, or nearly infinite”, here in California’s great Valley that isn’t really a long distance, 30 miles would be a much clearer day.)

  • Spork says:

    You forgot the step “????” That should be step 3 and 4 should be profit.

  • D_ says:

    Oh my God! The dude could be sent to Gitmo to be water boarded, to reveal his terrorist connections. That or on BSer was BSin another BSer Anyway in many States any thing extends 3 feet past a vehicle taillights has to have a red flag during the day and a red cluster light at night. God dammit I forgot to take the cluster light off before lighting it up again, gotta buy a new one,again. Driving that thing down the road in cattle country ma set off a stampede.

  • erica says:

    My solution for tailgators isnt that extreme.. though I am impressed.

    I just start washing my windsheild with fluid. If they are too close, it smears the tailgators windshield. he smears it wiping it,. learns a lesson

  • This thing is great. His site is funny. You can really pick up on his humor as he describes some of the tech details.

    I’d love to see that scooter with dual mounted jets.

  • John says:

    1) Someone mentioned to quote the law that says that’s legal… I think the idea is to quote the law saying that it isn’t legal.

    2) Even if a cop does flash his lights, if he catches you to give you the ticket… then you’re doing it wrong.

  • Space Cowboy says:

    A Honda Metropolitan with dual jet engines? Pardon me while I cringe, but that looks like an awfully good way to get oneself or one’s wife killed. It looks awesome, but many suicidal things look awesome until they’re removing you from the pavement with a spatula

  • nicco says:

    lol, and the old air-cooled vw guys thought they should be concerned with a fire in back!

  • PolyJetter says:

    Where else would the air intake reasonably be located except inside the vehicle? He could have used a longer jet engine and located it outside of the car but I think that is about the point where this mod (from like 1995) would have gone from extreme to bordering on pointless. Still, a fun exercise though.

  • nicco says:

    @PolyJetter

    as cmholm mentioned, there is always the possiblity of an air scoop on the roof. he might be able to cut a circle in his windsheild and run a straight-through intake. although that would probably make reaching the glove box from the driver’s seat a real bitch.

  • mike says:

    Totally awesome, though he should channel the intake to some side scoops or something.

  • EquinoXe says:

    Forget the beetle, check the WIFE’s scooter on his page!!

  • SuperSparky says:

    OK guys, this is a very old story (more than five years). However, back when it came out there was an interesting following. I live in California and do know that this car is street legal. It’s true, the DMV has tried to make it illegal, but due to the inconvenience of something called the US Constitution, they cannot do anything about it, except make rules for new cars.

    It is illegal for any government in the USA to make a law that is retroactive (a legal term called “Ex Post Facto”). The laws that apply to this vehicle are the ones in effect at the time the car was manufactured. This means it qualifies as a hybrid and an alternative fueled vehicle.

    This engineer was smart. He didn’t modify the original drive train at all and therefore cannot be used as an excuse to remove it from the road. It is smog legal, according to the law. It is a hybrid, according to the law. It qualifies as an alternative fuel vehicle, according to the law (although he doesn’t make any attempts to exploit the exceptions given to such vehicles). It is mechanically safe, according to the law, as it retains all of its factory safety features and has additional ones added to strengthen that requirement.

    The fuel is expensive and he rarely fires it up, except in a controlled area. It’s mostly functional eye candy.

  • Ben R says:

    About the scooter — It isn’t done. Notice the milk crates? And yes, it is terrifying – I have a Metropolitan and going 40mph is scary, let alone what those engines could make it go. Still.. I clicked through excitedly when I heard them say it was done. Still not, though, after all these years.

  • fartface says:

    Note: it does not take a degree in engineering to do that. A high school dropout can put a different engine in anything else. All it takes is mechanical aptitude. Jet engines are actually EASY to deal with if you take the time to understand them. A friend put a helicopter turbine engine in a car and that was actually quite easy, the hard part was coming up with a system to connect to the transmission, he gave up on a stick shift and went automatic transmission as that worked well with the turbine’s output.

    People try to show this stuff as if it’s difficult or requires an advanced degree. It does not. All it takes is a mechanical aptitude and being able to read and learn.

    Oh and the ever hard to get part….. Money. Jet engines are not cheap, Helicopter turbines are not cheap. Putting a GM LT1 into a mazda Miata is cheap if you know where to get the stuff for free or cheap….

    And yes, I have done that. It’s not hard.

  • PolyJetter says:

    “as cmholm mentioned, there is always the possiblity of an air scoop on the roof.”

    That would have to be a huge air scoop though to meet the needs of this turbine!

  • apollo says:

    C’mon Hackaday – i saw this YEARS ago.

    however at the same time, its very clever how he got that motor to do what it does now.

  • Torque says:

    I think the point is that there isn’t a law disallowing it, which is how many laws work. Look up selling babies in MI in around ’97

  • Myke says:

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

    You fucking fail at South Park humour, Mike.

  • Edd says:

    @Mattj – +1

    It’s street legal for it to be there, not to be used, as with everyone else, I saw this a while back so I’m not checking this for clarity but I recall reading it and him saying it’s classed as a hybrid because of 2 engines, of course I’m sure that was tongue in cheek.

  • Hacksaw says:

    While thing that gets me about it is the fact that he said it hadn’t been done before. Chrysler built jet cars in the ’60′s.They were never sold but there are still 2 around today.

  • GCL says:

    @Hacksaw
    Wrong!
    Chrysler built gas turbine powered cars. They used the same style turbines that Jet Engines wear, and in fact chose the ones that GE makes for powering navy ships, and geared them accordingly.

    However they were lousy on milage, and ate fuel the way teenagers eat hamburgers. The ones that were built were largely museum pieces, I believe one might be owned by that dolt Jay Leno, and one other might be sitting in their museum.

  • James says:

    There was a twin jet powered MR2 on ebay about 6 years ago IIRC.

    That must be **SO** loud in the cabin… Jeez!

  • Bensawsome says:

    This brings a new meaning of “burn in hell” to tailgaters :)

    I’m the person who owns the van mentioned here.

    I challenge Mr.Patrick to a 1/4 mile grudge race.

  • Bruce says:

    You guys are missing the point. The guy built this thing as an engineering exercise – not as any vehicle intended to be a daily driver in full compliance. I was a cop for 25 years, and I can tell you that in my state there is nothing there that would disqualify this thing from being on the road – safety inspection or otherwise – as long as the jet isn’t fired up. The ONLY possible problem I could see – at least in my state – is that the law prohibits anything extending 3 feet or more from the rear of any vehicle unless it has a red flag attached. Easy enough to remedy that!

    Get a sense of humor, for Christs sake – he did a great job engineering that thing. And any cop that would break his balls over it needs to seriously rethink his choice of occupation. I’d stop him for one reason – to admire how the hell he built it!

  • turbochris says:

    Ron Patrick. I’m throwing down the glove. Grudge race. 1/4 mile. Heads up.

    Jet Beetle vs Turbine Minivan

    The first daily driver jet race.

    It will be epic……

  • Ragnar says:

    I had considered putting one of those million candlepower spotlights on the back of my car for the tailgators, for when the “brake check” doesn’t work. Also useful for the people who get behind you with their brights on.
