The baseline figures show 660 horsepower to the wheels which is over 100 wheel horsepower per liter but this is with some tuning so we do not have a stock run to reference.
Regardless, to achieve that output naturally aspirated on a motor as large as a 6.5 liter V12 is what sets Ferrari apart. This is the kind of thing that before the turbo era would have Ferrari worshipped and unrivaled.
Tuning a car like this is rare and not easy as there is not much left to squeeze out. Yet, Dyno Spectrum was able to get another 52+ horsepower at the wheels:

Remarkable stuff and we would kill to see the full dynograph and curves. Notice the bottom pull has peak horsepower at 9120 rpm. A V12 revving over 9000 rpm and making power past 9000 rpm to boot, holy crap!
Now if someone had the balls to supercharge one of these bad boys...
