He was brought on to hedge the company's bets with a different engine family than the small V12s designed by Gioacchino Colombo.
All were quickly abandoned due to changing engine displacement sizes (because, starting in 1958, the sports regulations required sport cars to have engines within 3 litres), with the Dino V6 and V8 taking the place of the fours and sixes and evolution of the older Colombo V12 continuing as the company's preeminent V12.
[2] The task of creating the new V12 for Formula One use fell to Aurelio Lampredi, who designed a 3.3 L (3322 cc) unit, with bore centres at 108 mm apart, for 275 S and 275 F1.
[4] Applications: Being unable to match Alfetta 158 performance, Lampredi upgraded the design to 4.1 L (4101 cc) for 340 F1.
Power output grew to 335 PS (246 kW; 330 hp) but the single-seater was used in non-championship race only and very soon replaced by even bigger engined Ferrari.
[6] All GT road cars used wet sumps, apart for dry-sumped 340 America having engine based directly on the 340 F1.
Now at 4.5 L (4493 cc) and 350 PS (257 kW; 345 hp) installed in 375 F1, Ferrari was finally able to beat Alfa Romeo, in the British Grand Prix at Silverstone.
New Weber 40IF4C carburettors improved power output to impressive 380 PS (279 kW; 375 hp).
This almost 5 L (4954 cc) engine shared its stroke with 375 F1 powerplant at 74.5 mm and developed 330 PS (243 kW; 325 hp) at 6000 rpm.
This improvement helped score victories at Le Mans and Carrera Panamericana that year.
[12] The same engine powered the last Lampredi V12-engined sports racing car, the 410 S, with some upgraded to four coils and twin plugs per cylinder for a maximum output of 380 PS (279 kW; 375 hp).
[17] Another TR with this engine, the 1957 500 TRC, was produced to comply with new regulations from C-section of the International Sporting Code.
[1] The F1 car, with 12:1 to 13:1 compression and two Weber 50DCOA/3 carburettors, pumped 260 PS (191 kW; 256 hp) from this powerplant.
With different carburettors setup, two Weber 42DCOA/3, output remained the same at 220 PS, which was enough for a third place at Le Mans.
Aurelio Lampredi designed a prototype Tipo 114 2,977.28 cc (3.0 L; 181.7 cu in) engine for the experimental 306 S sports car that never raced.
[30] Applications: A bigger Tipo 118 3,747.48 cc (3.7 L; 228.7 cu in) version was installed in the short-lived 376 S sports car (also known as 118 LM) converted from 306 S chassis in 1955.
[31] Applications: Enzo Ferrari and Aurelio Lampredi were interested in creating extremely reliable engines for racing use.
The engine produced 175 PS (129 kW; 173 hp) at 4800 rpm on the test bench, but broke the crankshaft due to poor balance.
