Hearing of Packards reminds me of
Garfield Wood who ploughed the fortune he made from his hydraulic dump truck invention into powerboat racing. This culminated in Miss America X.
Hearing of a British challenge to the powerboat trophy he had held for nine years, using a pair of more powerful Rolls Royce engines, he added a further two V12 1600 hp Packard Aero engines. Each inline pair were carefully timed to run as one V24 engine to avoid drivetrain issues. A little tweaking got the total output to nearly 7000 hp!
Needless to say he won in 1932 with a record speed of over 125 mph from the 39 foot long, 8 ton boat, and again the following year despite a closer British challenge.
