💡 How do aluminum pulleys improve engine performance compared to iron ones in older vehicles?

Switching to lighter materials removes excess mass from the crankshaft accessories to boost throttle response quickly.

- Reduces rotational mass allowing the engine to rev up faster during operation

- Disperses heat more effectively to the surrounding air compared to steel units

- Prevents seizure issues caused by corrosion buildup inside the bearing housing

- Works better with long water pump configurations to maintain proper timing tension
