I'm curious about the engineering behind Lamborghini's iconic V12 engine. Specifically, how does the engine design allow for 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 greatly appreciated.
How does Lamborghini’s V12 engine achieve such high-revving performance?

From what I've observed, the key is the short-stroke, oversquare design paired with a lightweight forged crank and high-flow, pneumatic-actuated valves that keep valve train inertia low enough for 9,000+ RPM operation. If you're aiming for the same quick response on a track day, ensure the engine is fully warmed up, use 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.
