A modified 5hp Briggs & Stratton engine can achieve speeds significantly higher than its stock configuration, often reaching between 30 to 40 mph depending on the modifications made, such as carburetor upgrades, exhaust enhancements, and tuning adjustments. The actual speed also depends on the vehicle it's powering, gearing, and overall weight. Enthusiasts often push these engines to their limits for racing or go-kart applications. However, performance can vary widely based on the specific modifications and setup used.
