When it comes to dyno numbers, no one out horsepowers SP-3, not even fuels that cost two and three times more. Unlike yesterday’s slower burning fuels, SP-3 has a fast burn formula that is designed for today’s sophisticated race engines. This fast burn formulation increases horsepower in 2-storke and 4-stroke engines with compression ratios of up to 15.5:1. SP-3 has shown a horsepower gain of up to 15% over the competition. It is trusted by engine builders in the most demanding of motorsports.
