RV Camshaft vs. Stock Camshaft

Comparison of 22re motors with different modifications 

Solid line:

  • Stock camshaft
  • 2.75 inch exhaust
  • Aluminum 2.75 inch intake 

Broken line:

  • RV "C" 261 degree camshaft
  • 3.0 inch exhaust
  • Aluminum 2.75 inch intake

Please note that the 3.0 inch exhaust associated with the broken line is not thought to produce more power with the 22re series motor; the vehicle tested anticipates future turbo charging. Exhaust pipe diameters exceeding 2.75 inches are not recommended on normally aspirated 22re motors. The RV camshaft is expected to produce more power with appropriately sized exhaust diameters.
