GSC Power-Division S1 Camshafts (Hyundai Genesis Coupe G4KF Theta) GSC Power-Division

The GSC Power-Division S1 cams for the Hyundai Genesis Coupe G4KF Theta are designed for those with the stock turbo up to the 550hp 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 20-50whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000-7500rpms, these cams work well on the stock valve springs.* Designed for a rev range of 3000-7500rpms* The S1 cams work well on the stock valve springs6060S1 ADV Duration Duration @ 1mm Peak LiftIntake 264 220 10.20mmExhaust 264 216 10.00mm
