This guy called Tyson Garvin is an endurance powerboat racer who has set the record for the run from NY-Bermuda and he has already built an insane 15.7L 12-rotor Wankel engine. This crazy built is about the same size as your average big-block V-8.The engine consists of 3 banks of 4 rotors each.The banks are kept in sync with each-other by a set of gears. He says this monstrous engine produces 1,400hp, but you know that this number can be changed thanks to race gas and turbochargers transforming this into an engine goddess. Furthermore we suggest to watch both videos where this engine runs so smooth and the second one that shows this monster on the dyno. Also feel free to share with us your opinion.
