I may be wrong on this but, your car isn't sucking in air at all underload. I am under the impression that the cylinders are actually void of air after a combustion event. Thus making a low pressure spot where the atmosphereic pressure rushes in when the valves open to equalize the void. So basically air is pushed in not pulled. I know big deal right? E-rams are still a joke and they will never work. Maybe you could mount an air compressor and tank in the trunk and wire up 100psi shop air bursts. Now that's got to be power for the same price!!!
