Product Overview

*Nitrous HP Camshafts* * Wider lobe separation and added exhaust duration from base XE series help shift the power to higher RPM to allow use in nitrous applications * Early exhaust opening helps scavenge the extra spent gasses from nitrous or forced induction * Better time slips for nitrous passes at the strip
