Let there be little doubt that plenty of horsepower can be found in the intake manifold design.

Ferrari just revealed its F12tdf with a 769-horsepower, 6.3-liter naturally aspirated V12. That’s nearly 40 more ponies than the F12 Berlinetta; and, as demonstrated in the above video from Ferrari, much of the increase comes significant changes to the inlet system.

First, the intake lost some weight by removing the Berlinetta’s protruding resonators from the front, then the plenum gained a little capacity with a wider profile. New dual-inlet throttle bodies were designed to complement revised air pathways to the cylinder heads. Also new are hydraulic actuators for adjusting the inlet trumpet height as the rpm changes. Basically, the Formula 1-style system adjusts the intake runner length — longer for lower rpm torque and shorter for higher rpm horsepower. Finally, Ferrari switched from hydraulic to mechanical tappets, which allowed a more aggressive cam profile for this engine that sports an obscene 13.5:1 compression ratio.

Ferrari says peak torque is 520 lb-ft at 6,750 rpm with 80 percent of that total available at 2,500 rpm. Redline for the F12tdf’s 65-degree V12 is 8,900 rpm.

The hardcore version of the Berlinetta, the F12tdf (the suffix stands for ‘Tour de France’) will go from 0-62 mph in under three seconds and tops out at over 211 mph. In one of the more unique modifications, the F12tdf incorporates rear-wheel-steering. Only 799 units will be built, and pricing hasn’t been announced.
