SUMMARY
This discussion focuses on optimizing intake runner length for a 1.6L 4-cylinder engine equipped with four 36mm carburetors. Key insights indicate that shorter intake runners enhance low RPM power, making them ideal for a zippy daily driver rather than a drag racing application. The relationship between runner length and power band is emphasized, with longer runners favoring higher RPM performance. The importance of side draught carburetors is highlighted, as they utilize short intake manifolds to maximize low-end power.
