Not Available

Nitrous HP Camshaft; Hydraulic Flat Tappet; 2800-6800 rpm; Adv. Dur. 284 Int./305 Exh.; Lift .575 Int./.595 Exh.; Lobe Angle 113 deg.;

Features:

  • Wider lobe separation and added exhaust duration from base XE series help shift the power to higher rpm where it can be used in nitrous applications
  • Early exhaust opening helps scavenge the extra spent gasses out from nitrous or forced induction
  • Better time slips for nitrous passes at the strip
  • Slight sacrifice of some torque and responsiveness to the base XE family for improved performance with nitrous oxide
  • Works best with COMP Cams® roller rockers and matched valve springs
  • The big question is which time slip matters more to you (normally aspirated or N2O-assisted)?
