i mean interms of performance in the engine ,
Does it mean that the presure its producing is more , will increase the temp and far greater combustion in the engine .
nothing related to clutch .
Post in another topic and I give you my thoughts.. cannot say 100% correct, but you can ask for second opinion or third one.. usually you ask 3 people, you get 3 different answers.. but mostly if you dig deep enough, the final result is the same.
Performance in an NA engine requires base knowledge on how the 4 stroke cycle works, and how it generates power.
Cams, stroke, compression, fuel, ignition timing, flow (intake and exhaust) all are some of the considerations when thinking about making power out of an engine.
