How do Unorthodox Racing adjustable cam gears give me more power?
Changes in the relationship between the crankshaft and the camshaft can increase HP in DOHC cars from 8-16 HP for normally aspirated engines and 12-24 HP for forced induction engines. SOHC owners can expect small increases in HP (2-4 HP) in certain parts of the power band. SOHC owner can also shift their power curve from the stock setting to low-rpm improvements (off the line enhancements) or high rpm improvements. Adjustments vary depending on whether the engine is SOHC or DOHC and whether it uses forced induction or is normally aspirated. We have found for stock and mildly modified DOHC engines, whether forced induction or normally aspirated, that 2-3 degrees negative on the exhaust and 1-2 degrees positive on the intake (again varying slightly from engine to engine) produce the highest overall gains throughout the engines RPM band. SOHC cam owners can adjust their cam for optimized low-rpm performance (amount of total adjustment varies from engine to engine and should be done in one
