Jellybean Posted December 9, 2014 Share Posted December 9, 2014 I am sure Chris Wilson will love this Anybody have any experience with this and advs, disadvs http://performancetrends.com/blog/?p=5 Oversquare vs undersquare referrs to the Bore/Stroke ratio of an engine. If the bore is larger than the stroke, the engine is considered to be oversquare. How much torque an engine can make is based on its cubic inches. Torque comes from how much air the engine caningest every intake stroke. The more the cubic inches, the more air it can take in every stroke. How much HP an engine can make is based on the total valve area. HP comes from the total air the engine can ingest per unit time, like every second. The intake valve it typically the largest restriction for air flow in an engine. Therefore, an engine with more intake valve area (total valves in the engine x valve area) can ingest more air than one with less valve area. Or, it can rev higher before it runs out of breath. Higher revs mean more HP. Quote Link to comment Share on other sites More sharing options...
