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.
