This miniature 3.5cc V8 is a work of art that actually works

Every once in a while I convince myself that I need to buy a tiny but functional engine. I’m not sure what it is, but the sight and sound of a little motor running makes me so happy. That’s why I’m even happier to show you one of the coolest micromotors yet: a 3.5cc V8 that can spin up to 10,500 rpm.

If you’ve ever played with internal combustion model cars, planes or boats, you know the tiny engines that power them. These miniature power plants are often designed for function rather than aesthetic beauty. This is where HuiZhou Toyan Precision Technology Co. comes in, with the wonderful Toyan Model Engine range. They are tiny works of art that actually work.

Toyan opened in 2015, building tiny power plants that increasingly look like scaled-down versions of recognizable real car engines. One of the latest, the FS-V800, is a small V8 that spins at 10,500 rpm and produces 4 hp. That means it’s taller than an Audi R8 V10, Chevy Corvette, SRT Viper, Ford Mustang Shelby GT500, Bugatti Chiron and countless other legendary cars.

Toyan’s level of detail on their engines is amazing. This FS-V800 is powered by two carburetors and is cooled by a working water pump. And just check out this calendar arrangement! It’s all recognizable to anyone who’s disassembled a full-size car engine, just shrunk to a tiny size.

Here is a rendering of all the engine parts laid out:

Of course, such an impressive engine requires proper testing. That’s where Chicago YouTuber Warped Perception comes in. The host has a knack for putting all manner of engineering projects through their paces, filmed in glorious detail with delicious slow-motion. Here, the FS-800 looks even better.

Toyan advertises a top speed of 12,500 RPM for this motor, but the example in the Warped Perception video only managed 10,500 and got hot in the process. At least from my perspective, it looked like the problem might be with the carburetor setting. The cooling system also had a ton of air in it, which probably didn’t help.

Still, even though the setup wasn’t optimal, the engine ran like a beast. I don’t do anything with R/C vehicles these days, but I’m always tempted to buy one of these motors, just to have it on my desk. Oh, I have bad ideas. If you buy some too, know that this little guy is quite pricey at US$1,800 ($2,499). Unfortunately, this makes this engine model more expensive than most full-size scrap engines. But you’d be hard pressed to put one on your desk.
