Amongst the more difficult machining tasks in the world are those involved in the production of internal combustion engines. Thanks to the Internet, it’s now possible to watch detailed videos of master craftsmen assembling tiny desktop V8 and V12 engines in home workshops with barely a CNC in sight. However, up until now, most of these builds have been left on the test stand to bark and wail away. No longer – [Keith] has decided that needs to change.
We’ve seen [Keith]’s work before – particularly, his 125cc V10 build, featuring fuel injection, dual overhead cams, and even a supercharger. With several micro engines under his belt now, it was time to put them to work – the V10 is getting a new home in a 1/3rd scale RC buggy.
We’re not sure [Keith] has heard the phrase “off the shelf” – even the suspension dampers on this build are custom machined. Currently up to part 5, the chassis is coming together and there are plans for a hybrid powertrain, too. Carbon fiber and anodized parts are in abundance – this build is truly a work of art.
We can’t wait to see this V10 monster tearing up the dirt – It’s an ambitious build, but if anyone can pull it off, it’s [Keith]. Video after the break.

Nearly three years in the making, behold the raw power and precision of this 1/3-scale V10 engine.
Coming in at 125 cubic centimeters displacement, [Keith Harlow]’s fuel injected masterpiece isn’t too far from the size of some motor scooter engines. We doubt the local Vespa club would look upon it as legit mod, but we’d love to see it. [Keith]’s build log is a long series of forum posts, but from what we’ve seen it looks like every part was made by hand with the exception of the fuel injection system. Even the caps for the spark plugs were custom injection molded right in [Keith]’s shop. And it appears that no CNC was used – even those intake headers and the rotors for the supercharger were hogged out of aluminum using a manual mill. The exhaust headers alone are straight up works of art. There’s a staggering amount of work here, which begs the question: why? The answer in this case is obviously, “Because he can.”
Few builds compare to the level of craftsmanship on display here. The Clickspring skeleton clock comes to mind, but for model engine builds we’d have to point to [Keith]’s earlier 1/4-scale V8 engine. And we’ll hasten to add that as much time as [Keith] has spent building these works of mechanical art, he’s probably dedicated just as much time to documenting them and giving back to his community. We can all learn a lesson from that.
