The Lingenfelter Power Formula

• Always maximize power within the rpm band where the engine spends its most time
  
  
• Vehicle application is far more important than most enthusiasts would believe
  
  
• Bigger is rarely better. "Small" intake ports, manifolds and exhaust systems maximize torque which improves that wonderful "seat-of-the-pants" feeling in street engines
  
  
• Port velocity will improve cylinder filling more efficiently, especially at and below peak torque, than big flow numbers generated by large, slow moving ports
  
  
• A strong cylinder head will always make more power even if poorly matched with the cam. A weak cylinder head matched with an optimized cam will never perform as well.
  
  
• Transmission & rear end rear ratios have a significant impact on engine component decisions. A good example of this is camshaft selection charts that emphasize cruising rpm - basing, in part, a cam profile on gear ratios.
