Click above for more pics of the Callaway Cyclone V16

Perhaps best known for his customized Corvettes, Reeves Callaway is also the brains behind a technical and engineering consulting company. A few years ago, he showed the world a V16 motor he built using four Yamaha 1,000 cc motorcycle engines mounted on a unique block. Dubbed the Cyclone, this 4.0L mill was good for 550 hp @ 10,000 rpm. While it is undeniably long at just over 36 inches, the aluminum block helps keep its dry weight down at just 334 lbs. Callaway used the Yamaha motors because his company helped develop their 5-valve heads and Reeves believes they are still among the best-built engines he has ever seen.

While the Cyclone project was started for little more than kicks and giggles, Reeves and his son Peter dragged it out to Cars & Coffee in Irvine, CA yesterday morning and hinted that we might be seeing this engine again soon, in the engine bay of a new Callaway show car. Alluding to such great automotive designs as the legendary Auto Union Type D, Callaway said we shouldn't be surprised to see this engine in something that marries that type of design ethos with a modern sensibility. No date was given for the car's debut, but Reeves said it will be completed eventually. Whatever it ends up looking like, we think we might like a ride in it. In current tune, the redline has been lifted to 11,500 rpm, allowing horsepower to swell to 640. it will certainly be entertaining.

      I want 'em to do a V8 version of this, and drop it into a Lotus Elise!

      I totally love the idea of small displacement/high cylinder count engines. High end cars don't need to go to fewer cylinders. They need to go to smaller cylinders, while keeping the same number of cylinders.

        Powetec already makes a V8, which is basically two Hayabusa engines... that's the motor Radical uses in the SR8, which incidentally is the same radical that smashed the Nurburgring record to pieces with that 6:55 run.
        • 6 Years Ago
        There are a few Hayabusa V8s, like the RST-V8 and the Powertec V8. They weight like 200lbs and produce up to 455hps.

      Can you imagine how long it takes to sync 16 throttles?
      • 6 Years Ago
      i really, REALLY want to listen to this thing run.

        Video and sound clip of the engine in action.
        • 6 Years Ago
        I wish the Sound/Video clip was of the engine romping it!
        It took them forever to max out RPM's-

        Either way, Thanks for the video link!

      I did, I already sold my first born for it

      " In current tune, the redline has been lifted to 11,500 rpm, allowing horsepower to swell to 640. it will certainly be entertaining."...

      ... not to mention it will sound f-ing amazing!

        • 6 Years Ago
        . . . and weighs a mere 334 lbs (for a V-16).

      Automakers need to focus on getting engines like this into mass production! Acura's NSX successor needs one of these.

        it probably has horrible gas mileage...

        it should stay as an incredibly insane & awesome show car engine
        • 6 Years Ago
        because lord knows when I go shopping for a 16 cyl, 600hp supercar, gas mileage is ALWAYS at teh top of my list....

        Ugh. Bigbear, here ya go, you look lost, let me help you: http://www.autobloggreen.com/

        haha I brought up gas mileage because the guy I replied to said it needs to go into mass production... A 600 hp engine that gets 3 miles per gallon isn't a good choice for mass production.
      • 6 Years Ago
      It looks cool but the HP isn't that impressive.

      Turbo Hayabusa's can make 500+ HP with 4 cylinders.
        • 6 Years Ago
        yeah you are right a hayabusa turbo engine is able to make 500 hp. keep in mind that this engine is for a motorcycle, so puting the engine with 500 hp in a much heavier car would probably blow the engine in a short period of time.
        • 6 Years Ago
        A Turbo R1 (which is what this Callaway is based off of) can also make insane amounts of power.

        But I'm assuming Callaway actually wants the engine to last. i.e. that can be driven around and not having to constantly worry about the engine blowing up like the turbo bike engines.

        Which is probably why they are keeping the rpm low(er) in the V-16 (the R1 has a insanely high-rpm)..
        • 6 Years Ago
        Maybe the power isn't the best, but sometimes you do things NOT to be the biggest and baddest, you just do them because you CAN. This is one of those times.
        • 6 Years Ago
        I think it's very cool... and the power production isn't that bad even when compared to 4 stock R1 engines... which you can't really do anyways. Motorcycles are able to make that kind of power largely in part to them spinning at higher RPMs: an '08 R1 doesn't hit fuel cut-off until 14500 rpm, while this was limited to 3000 rpm less . Beefier crankshaft means more rotational inertia, and more power is going to be absorbed to get that bigger crankshaft & flywheel moving compared to your standard fare R1 items.

        And HP is just one part of the equation: this thing will have a load more torque than any turbo 'Busa. Low torque is why you don't see motorcycle engines... turbocharged or not... in road cars other than lightweight track toys. This thing should power a proper road car with ease.
        • 6 Years Ago
        This article and Callaway is touting the horsepower from this engine. As I said, I'm not impressed. If you took 4 stock Yamaha R1 engines times 4 you would have 720HP. So this configuration doesn't even match the stock configuration in terms of horsepower per liter.

        I could think of a lot better ways to spend hundreds of thousands of dollars......
      • 6 Years Ago
      I would like to see a video of it hooked up to a dyno.
      Would the engine fit in a corvette or new camero engine bay? the weight is really low, would give a killer handling car.

      Imagine doing that valve job... 80 valves!!!
        • 6 Years Ago
        @HotRodzNKustoms
        Haha Valve Job.

        That would be a Bitch!

      It kind of reminds me of a aircraft engine.
      • 6 Years Ago
      We need some sound clips of it running. Its got to sound bad ass up at 10k rpm. It must have F1 like throttle response too.
