GSC POWER-DIVISION Billet S1 Camshaft Set [ADV Duration I264-E264 | Duration @ 0.040" I216-E220 | Peak Lift I10.20mm-E10.00mm | CL I115-E120] (MITSUBISHI Lancer EVO X)

The GSC Power-Division billet S1 cams for the Mitsubishi Evo X are designed for those with the stock turbo up to the 550 HP range. These cams will not sacrifice any bottom end loss over stock cams; nothing but gains, and will promote faster spooling of the upgraded turbos. Gains of 20-50 WHP (depending on turbo) have been seen by simply bolting the S1 cams in.

• Designed for a rev range of 3000-7500 RPMs
• The S1 cams work well on the stock valve springs
• Forged billet core
• Made 100% in the USA
