Ram air makes it easier for the intake to suck in more air faster, but it is still the same amount of air per compression cycle.
I don't agree. how do you make more power at one point if there is always the same amount of air per compression cycle, or compression stroke? or are you referring to something else by "compression cycle"? if you are, I don't know what you mean. please explain.
assuming correct design and fabrication, the effect of the air being collected into a pressure point at high speeds creates higher than atmospheric pressure on a filter surface (street application). the greater pressure on the outside of the filter results in more air inside the Intake
system at greater than atmospheric pressure. this results in more air molecules consumed on each Intake
stroke and more molecules compressed on each compression stroke.
air from a ram air system at speed is also compressed at higher than atmospheric pressure, albeit not much higher. however ram air is not put into the same category as the devices comprising forced induction because it is on the whole...natural, dependent on the environment (air) acting on the car, not as effective and NOT dependent on a function of the car's engine as the sophisticated systems in forced induction (F/I) are. thus ram air is still counted as normally aspirated or naturally aspirated (N/A) and is used by pro sport compact all-motor racers. btw, normally/naturally aspirated is the same as all-motor.
trikdcelica, I highly recommend you go to howstuffworks.com and read up on superchargers, turbos, and nitrous oxide systems.
you may say you don't have the cash for a turbo or S/C, but to be honest if you go with ram air you may just end up with a funky looking CAI
(Cold Air Intake
) coming out of the left side of your Hood
. Though I'm sure it will perform well because the tube will have one bend, and it will be short.
IMO if you want to go all-motor, just get a TPR Cold Air Intake
That is unless you have deep pockets to empty on R&D for a ram air system that will work for the Celica. and if you were that serious, you'd develop an Intake
manifold to work with individual throttle bodies. $$$ not to mention the MAP sensor conversion to work with them. that would have the best ram air effect. and then you would have a Hood
scoop low and in the center of the Hood
