Many vehicle power insufficient faults trace back to worn camshaft lobe surface, wrong replacement camshaft parameter cannot recover original vehicle dynamic performance. Different engine displacement and fuel injection mode require targeted camshaft parameter matching scheme during overhaul replacement.
High lift camshaft lifts engine valve higher to increase intake air volume for high speed power promotion. Standard OE camshaft lift balances low speed torque and high speed horsepower for daily driving. Over large non standard lift cam creates unstable idle and low speed power weakness problem.
Long lobe duration camshaft expands medium high speed torque interval for turbo engines, short duration original camshaft focuses low speed pulling force for naturally aspirated vehicles. Mismatched cam duration narrows effective power output range of whole engine assembly.
Induction hardening camshaft lobe surface resists long term engine valve tappet friction without pit abrasion. Soft untreated cam lobe wears rapidly after tens of thousands kilometers, reducing valve opening stroke and weakening vehicle acceleration response obviously.
Camshaft gear tooth pitch must keep consistent with timing chain kit sprocket, mismatched tooth count shifts valve opening timing angle, generating engine misfire and high fuel consumption. Complete camshaft with matched gear reduces separate gear replacement extra cost.
