However the Eram is not a reputable item, it is garbage, please do not waste your money. The gains you see from the echarger from power off- to power on-- come from the fact that when you install it-you are putting a restriction in the flow path. This hurts your performance. When you turn it on, The restriction becomes invisible because it spins with the amount of air you normally would. You really are not getting "gains" , you are merely getting the car back to where it was originally. The cfm rating on the trash is rated under no-load conditions. If you dead-headed the fan, you would no way produce any real psi. when the motor is running, it is pulling a lot of air through it. If the fan cannot produce it with no flow, then it surely won't do it with a flow already.
