[QUOTE="SpeedWanker, post: 51494, member: 311"] hahaha.. this is getting interesting! :D okok.. lets see.. high temp air= high energy within each air molecule= more distance between each air molecule = low air density...therefore high air temp=low air density and low air temp= high air density.. so when high air temp is reduced by cool fine water spray the air molecule will loose its energy and 'clump' together. The closer they 'clump' together the more oxigen molecules u'll get in the same volume.. Also if the water is being sprayed fine enough it'll have a very large surface area to absorb large amt of heat from its surrounding and hence transforming its current state(liquid) to a gaseous state which will not affect the amount of inlet volume.. Another thing is that temperature will not affect the volumetric efficiency.. engine capacity, construction of ports, type of throttle body, type of air metering device and type of air filter will affect volumetric efficiency. One more thing is a cooler intake charge will not reduce the combustion temp since the cooler the intake charge the more oxigen and fuel u can pack into an engine, the more violent the explosion of the charge will be hence increasing the combustion temp.. cheers ;) [/QUOTE]
