People need to learn that major performance comes at a price. I too looked into an E-ram, but I was designing my own that would throw about 8lbs of boost. RC electric jets can produce from 1-14lbs of thrust. I am into RC jets (designing and building) and got the idea

one day (when I had a POS pontiac Fiero) to make a custom mount to run an RC electric Jet engine producing 5lbs of thrust to my airbox. I noticed a major difference, but it was not a reliable way to do it, and running it at high throttle would wear the electric motor down way too fast. You would be replacing E-ram motors every 1-2 weeks with normal driving. I had my wifes uncle who is an electrical engineer for Texas instruments help me out. We found out the hard way that an E-ram that would put out more than 1.5lbs of thrust would take too much juice. I ended up scrapping the project and using my special 8lb e-ram to build an RC vertical take off jet (which has chrashed a few times during testing, oh well).
