The eram consumes 50 amps @ 13 volts so that's 650 watts and 1hp is 746 watts...figure the alternator is only 50% efficient, that's 1.74hp MAX consumed by the motor...now it produces around 1psi of boost (based on the airflow capabilities of the motor) and 1psi usually equates to around a 8% power increase. So on a SVT 200hp*.
08=16hp-1.74hp=14.26hp.....
14hp is nothing to sneeze at considering thats more than an intake and exhaust together gain.
