TG.com rides shotgun in Fiat’s 21.7-litre demon
Behold, the aircraft-engined 1908 ‘Mephistopheles’, built to break records and scare humans

Step forward our protagonist and speed-demon, Sir Ernest Eldridge. He bought the scrap remains of the Fiat following Duff's fiery exit, and rather than repair the existing 18-litre behemoth, instantly (and correctly) decided more was needed. He fixed his mind on sourcing an aircraft engine for the SB4, and settled on Fiat's A.12: a straight-six, single-cam unit with a capacity of 2,1706cc.
To give you some context, this straight-six was used in Italian reconnaissance and bomber aircraft, providing a suitably thunderous heart for Eldridge's speedy plans.
