    • Most of these older jet engines take a very looong time to reach 100% power, something like 20-35 seconds. Not suitable for impressive jack-rabbit-like starts. You'd basically have to jam on the brakes, hit the accelerator, and --wait-- 30 seconds for the power to build up. Not very impressive.
    • There's, ahem, a big safety problem for bystanders-- these early engines were not rated to contain their blades if something bad happens. if the engine intake ingests a small rock or loose bolt, the thing could disassemble in a hurry, with white-hot pieces of turbine blades heading out in all directions. Not a healthy environment to be standing around!
    • The rotational momentum of 10 compressor and one power turbine sections is going to be significant, and not in a good way. This car probably needs a very flat aqnd level and straight highway. Any bump is going to cause all kinds of gyroscopic precession around the center and axis of momentum, which is NOT a good thing.

      It's a good thing you thought of all this stuff, and the Stanford Ph. D. holding owner of a firm called Engine Control and Monitoring didn't. Boy, you'd better call him before he goofs! Thank god for you!

      Everyone's an armchair expert. Also, RTFA, it says when he kicks in the engine, he first gets the car up to 90 miles an hour using the conventional engine in the front of the car.

    No, not the myth of the man strapping ICBMs to his impala.

    They were JATO (Jet-Assisted Take-Off) rockets, not ICBMs (InterContinental Ballistic Missile).

    A JATO rocket is used to give additional thrust to an airplane so it reaches its takeoff speed faster and can thus rise from shorter runway. An ICBM is used to lift an atomic bomb into space and drop it to another continent from there.

    Just a little difference in size and engine power there ;).

    I mean, come on. He doesn't have the engine actually hooked up to any gears to turn the wheels. He just has it mounted on the back of the car, and he's relying on the engine thrust to push the car along.

    Trouble is that that kind of engine isn't designed to do that. It's a T-58 engine, a turboshaft engine off of a helicopter. While the engine on a jet is designed to shoot lots of hot air out the back, producing thrust to drive the jet forward, turboshafts are designed to, well, turn a shaft, to turn a rotor blade. In other words, they're torquey, not thrusty, and helicopters don't go fast because of the engine exhaust, they go fast because of the rotor.

    I was looking to buy a (ex-Soviet) MiG 15 or MiG 17 jet engine.

    He'd have been far better off doing that. The engine off a MiG-17 develops 6,000 ft-lbs of thrust.

    I mean, look what kind of performance he gets with his 1500-horsepower jet engine:

    He said that a jet-boosted run will "pin the speedometer and that's at 140." He thinks that when it hits 160 mph -- he hasn't seen that ... yet -

    140? My 300-horsepower Mustang GT is perfectly capable of hitting 140, and would probably do 160 if a governor doesn't kick in. 1500-horsepower is the power of the gas turbine in an M-1 tank; if he had this thing hooked into the drive wheels, he'd go like a bat out of hell. But as it is, all he's doing is making a lot of noise.

    Which I mean is fun and all, but fundamentally, he doesn't have a jet-powered car. He's got a car with a jet engine in the trunk.

      In a more detailed article, they reported that he converted the engine to a turbojet by taking out the shaft turbine, the gearbox, and sticking in a nozzle. Since a turboshaft is just a turbojet with these extra components, it's quite a reasonable conversion.

      No, that's a gross oversimplification. The bypass ratio of a high-thrust jet engine and that of a high-torque helicopter engine are entirely different, and you don't change that significantly with the described modifications. He's still got an engine designed to produce a lot of shaft horsepower, and you don't get a lot of thrust out of that just because you remove the shaft.
