MERCURY RACING 1025/1075SCI STAGE 2

The Whipple Stage 2 system for Mercury Racing 1025/1075SCI engines boasts even more power than Stage 1 by removing the stock camshaft and valve springs for a more agressive setup that works best with the supercharger system. The results are an astounding 100HP and 100 pounds of torque more than stock. The factory rpm limiter is also increased, giving customers the ability to greatly increase top speed MPH while running original props.
