Ferrari Dino engine
Appearing in 1958, it used a 77 mm × 71 mm (3.03 in × 2.80 in) bore and stroke for 1,984 cc (2.0 L) and produced 200 bhp (149 kW; 203 PS) in the 196 S. A larger version was also produced, the 245 bhp (183 kW; 248 PS) 2,417 cc (2.4 L) Dino 246 S. These engines continued in the 1962 Ferrari 196 SP and 286 SP.
Thus the engine was as smoothly running as a conventional 60-degree V6, but had greatly enhanced potential for the design of harmonically balanced exhaust manifolds, giving much better performance.
In compared with racing 206 S version the engine of road 206 GT was detuned to 180 PS (178 bhp; 132 kW).
The same V6 engine was handed off to Lancia for use in its WRC-champ Stratos in the early 1970s, but Ferrari's Dino had moved on to 8 cylinders.
Applications: 4 valves per cylinder were added for the 1982 308 and Mondial Quattrovalvole (or QV), bringing power back up to the pre-FI high of 245 PS (180 kW; 242 bhp).
The engine was twin-turbocharged and destroked to 2.65 litres, but produced 720 PS (530 kW; 710 bhp) in qualifying trim.
Applications: These small V8 variants were chiefly intended for the domestic market, where cars with engines larger than two-litre incurred in an almost doubled 38% value added tax.
Applications: The turbo also served as a development platform for the forthcoming 1984 288 GTO sports car.
That famous Ferrari was meant for Group B racing, with a 2,855 cc (2.9 L) version of the 308's engine (bore was down by 1 mm (0.04 in) to meet the regulations of the class).
With IHI twin-turbochargers, a Behr intercooler, and Weber-Marelli fuel injection, the GTO boasted 400 PS (294 kW; 395 bhp) from Dino's engine.
The engine also features double overhead camshafts with four valves per cylinder, as well as Weber-Marelli fuel injection and dry sump lubrication.
The 2.9 L (2,936.25 cc) Dino-based engine now had a bore x stroke of 82 mm × 69.5 mm (3.23 in × 2.74 in) and 16 psi (1.1 bar) of turbo boost for 351.5 kW (478 PS; 471 hp) at 7000 rpm and 577 N⋅m (426 lbf⋅ft) of torque at 4000 rpm while the US designated engines, code named the Tipo F120 D were rated at 356 kW (484 PS; 477 hp).
Applications: The Tipo F120 B, used in the Ferrari F40 LM, retained the same displacement as the F120A, but the output of the IHI turbochargers was upped to 2.6 bar (38 psi) and the compression ratio was increased to 8.0:1 for 720 hp (540 kW; 730 PS) at 7500 rpm.
Applications: The 1994 F355 included their first production 5-valve engine, and sported a 2 mm (0.08 in) longer stroke for 3.5 L (3,496 cc) and 380 PS (375 bhp; 279 kW).
Modifications to the intake/exhaust and an increased 11.2:1 compression ratio produced 425 PS (419 bhp; 313 kW) for the 360 Challenge Stradale.
