I'm curious about the engineering behind Lamborghini's iconic V12 powerplant. Specifically, how does the engine design allow such high RPM limits and rapid throttle response compared to typical naturally aspirated V8s? What role do factors like bore‑stroke ratio, crankshaft balance, and valve timing play in achieving the characteristic scream and torque curve? Any insights or resources would be appreciated.
How does Lamborghini’s V12 engine achieve such high-rev performance?

From what I've seen, the key is the short‑stroke, oversquare design combined with a lightweight forged crank and high‑flow, pneumatic‑actuated valves that keep the valve train inertia low enough for 9,000 + RPM operation. If you’re looking to get the same quick response on a track day, make sure the engine is fully warmed up, use a high‑octane fuel and keep revs in the sweet‑spot (7–9k RPM) where the V12’s torque curve is flat and the exhaust “scream” is most pronounced.
