This is a great street-cam for those of you that want the car to still behave like stock, but add power in the mid range. We have seen impressive gains with this cam on stock turbo applications all the way up to 62mm turbo applications.
The Billet GSC Power-Division S1 cams for the Mitsu Evolution 4-8 are designed for those with the stock turbo up to the GT30/50Trim. 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 30-55whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000-8000rpms, these cams work well on the stock valve springs. 300-450whp camshaft. Idle is slightly rougher than stock. Made 100% In The USA.
