    Stinger 609:
    World's Smallest Supercharged Four-Stroke V-8 Enters Production

    Big Pic
    Unless you're into model cars (like, really into them) you may not have heard of Conley Precision Engines.
    They build the Stinger 609, the world's smallest supercharged four-stroke V-8 engine, which has finally entered production.

    At just 6.09 cubic inches (hence the name), 99.8cc, it's a very small displacement V-8. Despite the small displacement, the engine revs to 10,000 rpm and produces 9 horsepower.

    At just 14 inches long, 6 inches wide, and 10 inches tall (with the supercharger), the highly miniaturized V-8 weighs just 11.25 pounds.

    The entire engine is custom designed and built by Conley, with painstaking attention to detail and a surprisingly public development process documented in the official build log.

    Unlike many of the alternatives in the quarter-scale model world, the Stinger 609 looks, sounds, and runs almost exactly like a full-size V-8.
    Unfortunately, that level of realism and excellence will run you $7,000 per.

    Does this have any practical value for anyone outside the model car (or perhaps the go-kart/scooter modifying) realm?
    No. But it's awesome, and we want one just to put on our desk and scare the pets.

    That engine dropped in a custom trike with a Quad's rear end, or in a big chopper bicycle would make for one awesome looking ride!

    Then again can you imagine the maintenance on that thing?
    Totally impractical but fun none the less ;-}

    I've wanted to build a miniature T bucket with one of those for a very long time. sadly, $7000 is about $6500 out of my price range

    They're actually more than $7K. KCvale's link is nearly 3 years out of date.

    Regular versions have ~5.5HP and start at a little over $8200.

    Supercharged versions start at a little over $10,600.

    They'd be extremely difficult to adapt to a bicycle, likely wouldn't live very long, and good luck replacing parts.

    Not practical for sure, but darn cool looking and they actually do run.
