too bad it won't fit in our bikes without a new custom frame.
Ride of the Valkyrie
To start, the Valkyrie engine is designed and manufactured by the legendary group at Cosworth, and is a 6.5-liter (396 cubic inches) 65-degree V12 layout, with a rated peak power of 1,000 horsepower at 10,500 rpm and 546 lb-ft of torque at 7,000 rpm, with a maximum engine speed of 11,100 rpm. It features dual throttle bodies and a unique 3-into-1 quad exhaust. “That gives it 153.8 horsepower per liter, which blows everything that came before it out of the water,” says Fenske.
EngineLabs readers weren’t the only ones that questioned how the Valkyrie engine was able to make so much horsepower naturally aspirated. Jason Fenske from Engineering Explained heard those same questions. Luckily for us, he was moved to make a video explaining some of the finer details of the 6.5-liter, naturally aspirated V12 powerplant.
