: it's got nothing to do with how much CFM the fan could handle.
: flow of air is always there even without the pressure. read your text book first.
: only when the pressure is apply to the volume we can now call it a *controlled flow*
: Don't waste any money on *E-Ram* charger thing.
: it's not a charger. it's just a fan.
: it's no good when E-ram can push 100,000,000 CFM while it can only pressurize upto 1 psig. intake will always draw the air that is needed for the specific rpm range and all else is wasted.
:
: Vp=amount of air needed
: Va=charger max airflow
: Pa=charger psig @ max airflow
: Pt=final intake pressure
: Pt=Vp-Va when Va : Vp=(Va/Vp)Pa-(Vb/Vp)Pb when Va : don't forget to add 14.9 psig on each P value. : : oh. and by the ways. it's a SCAM. Don't buy E-Ram product because it's waste of your money. : let's say that you have 3.0L car and it requires 300 CFM@6000rpm. : Vp=300 : now you have a blower (axial fan) blowing the air at the rate of 750CFM @ 1psig over 14.9psig. : so : Pt=(1)1psig : not really : and now because of this E-ram thing.... you're able to create 300CFM @15.4 pisg. it's not 750 CFM. and do you know why? I hope you do cuz if you don't.... read the subject. that's who you are. : so let's calculate the Horse power! : 14.4:200 = 15.4:X : 14.4X=200(15.4) : x=213.89 HP : your gain is 13.89 HP : yeah.. you gain a bit. you do.. but let's think for a minute. where did the rest of 750CFM went? : so there you have it. all the mysterious BS about E charger. and why it can and cannot make the HP you deserve. : because the stupid moron used axial fan. : if he had a minimum educations on simple physics, then he should know very well that axial was a bad choice. : my answers to you morons. : you only need a blower that can handle... hmmmm
: let's test plug in some numbers for the E-charger.
: simple right?
: let's say that your car is making 200hp @ 6000rpm.
: at the rate of 300CFM @14.4 psig (considering the negetive intake pressure)
:
: if you're smart enough then you already know that E-ram didn't get 750CFM when it is installed to your car's intake. as a matter of fact, it only drew 300 CFM. and I think I told you the reason why.
: let's say.. 300CFM @ 7psig . that's it.
: anything that is more then 300CFM is complete waste of your money and electricity.
