The GSC Power-Division S1 cams for Mitsubishi Evolution 4-8 are tailor-made for vehicles equipped with the stock turbo up to the GT30/50Trim. These cams ensure no compromise in bottom-end performance compared to stock cams. On the contrary, they offer significant gains and contribute to quicker spooling of upgraded turbos. Users have observed power increases ranging from 30 to 55 wheel horsepower (depending on the turbo) by simply installing the S1 cams. Operating within a rev range of 3000-8000 RPM, these cams are compatible with stock valve springs and are optimized for engines producing 300-450 wheel horsepower. Expect a slightly rougher idle compared to stock cams. Upgrade to GSC Power-Division S1 cams for improved performance across the RPM range.
