Check Out This Fully Functional, Supercharged Scale Model Engine


With all of our brand spankin’ new 2011 calendars marking just the sixth day of January and the literal dead of winter upon us, it’s right about the time many racers begin to go senile, unable to control their confinement to their snow-covered race shops and looking for any way to entertain themselves for three to four more months. So we scour the internet looking for anything interesting and race-related and in doing so, we found something that might tickle the fancy of any racer or gearhead. And if so inclined, said racers and gearheads could even acquire one of these to tide them over until the new racing season.

For those who aren’t particularly alert and notice the relative size of the items in the background, you may not realize just how small this dragster is until you see a hand reach in to fire the motor. But what you’re looking at is remote controlled dragster powered by a Stinger 609 – a real, working scale engine from Conley Precision Engines. Measuring 6.09 cubic inches or about 100cc, with a 1.000″ bore and .970″ stroke, it weighs in at a scant 11-1/4 pounds and is approximately 14-inches long (from the timing belt to the end of the transmission).

The cylinder heads feature large oval shaped intake ports, D-shaped exhaust ports. The engine utilizes a dry sump oiling system with a three stage oil pump that pumps the oil collected in the pan back into the engine, just like the big boys. This little wonder also sports an actual electronic starter unit that uses a 12-volt electric motor and is a fundamental part of the engine. The drivetrain is finished out with a working centrifugal clutch.

A supercharger setup like that seen in this clip are offered as optional equipment. The naturally aspirates version of the Stinger V8 produces an impressive 5.5 horsepower at 9,500 RPM and comes fully dyno tested and tuned. While these are about as cool a “toy” as they come, the price isn’t for the faint at heart. The non-supercharged base engine will set you back $5,695 while the supercharger kit runs $1,695 and other options such as exhaust manifolds, camshafts, and valve covers run in the hundreds. Regardless, this is one cool little engine and you have to give props to Conley Performance for having the patience to work with something that small and tedious and making it function like a real engine.
