GSC Power-Division Billet Evolution X S1 Camshafts (gsc7010S1)

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. Features: 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 If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case
