12-Rotor Engine: A Glimpse into a Unique World

The world's only 12-rotor engine, built by Tyson Garvin of Apex Manufacturing and Design, has been showcased by YouTuber Rob Dahm. The 15.7-liter engine is capable of hitting 10,000 rpm and producing up to 800 pound-feet of torque at 2,000 rpm, with a potential power output of 1,400 horsepower. While the engine was initially designed for speed boat racing, its dimensions and bolt pattern are compatible with Chevy's big block engines, allowing for various swap opportunities. However, Dahm highlights several challenges and design flaws in the engine.

"Revolutionary 12-Rotor Rotary Engine Unleashed"

Apex Manufacturing and Design has built a twelve-rotor engine for speed boat racing, which is the exact shape of a Big Block Chevy. The engine made 800 lb-ft of torque at 2000 rpm and can spin past 9000 rpm. The need for it to run at wide-open-throttle for hours sounds like solid ground for a rotary design, which usually works best at high rpm.

"12-Rotor Rotary Engine Sets World Record"

The world's only 12-rotor rotary engine, designed by Tyson Garvin from Apex Manufacturing and Design, has been featured on YouTube by Rob Dahm. The engine is the same size as a Chevy big block V8 but has 12 rotors, making it capable of producing around 800 lb-ft of torque at just 2,000 rpm. The team plans to disassemble the engine to build on Garvin's creation and document the process on Dahm's channel. The possibility of turbocharging could give this engine the power to rival electric hypercars.

Insane 12-Rotor Wankel Engine Built from Scratch at Home

YouTuber Rob Dahm has received a 12-rotor Wankel engine from Tyson Garvin, who built it at home. The engine displaces 15.7 liters and can rev up to 10,000 rpm, producing up to 800 pound-feet of torque at 2,000 rpm. It is enclosed in a big block the size of a Chevy V8 and consists of three 4-rotor banks in a Y configuration. The engine has not been fitted into a car yet, but Dahm has previously built a 4-rotor Wankel engine for his Mazda RX-7.

Rob Dahm Receives 12-Rotor Engine, Sparks Concern.

YouTube personality Rob Dahm has been given a handmade 12-rotor engine, the most rotors of anything ever, which he plans to bring into the modern era with fuel injection and possibly even forced induction. The engine was originally built for a drag boat and never ran on more than carburetors and a pair of V12 Jaguar ignition systems. The teardown of the engine shows incredible engineering and is worth watching.
