That’s why it was nice to see this one on the dyno. The modifiers had a little bit of fun with it too. They converted the engine to EFI and installed a twin turbo setup. The turbos create 6 psi of boost pressure, and the engine puts out 650 horsepower and 600 ft. lbs. of torque when run between 3500 and 7500 rpm.

This was the engine of choice for the Ferrari Testarossa, which ended its run in the mid 1990s. The Testarossa’s boxer engine was a naturally aspirated 4.9 liter mill which propelled the car with quite respectable performance for its time. However, the Ferrari 4.9 liter flat 12 has been mostly forgotten in the 20 years since its production.
