Does the e-Ram put a large drain on the alternator?
No, the max current draw is 60 amps for the e-RAM, and 120 amps for the Super e-RAM. This is as much as a high powered stereo, headlights, electric radiator cooling fan, or the starter motor on your car. Most car batteries with over 200 cold-cranking amps can handle draws of over 100 amps while the engine is running with no problems. We have even tested the e-RAM and Super e-RAM on motorcycle electrical systems with no problems. The e-RAM generates up to 15 hp gain from drawing over 1hp (831watts) directly from the battery. This has been verified on the dyno and with Volt Meters and Amp Meters. Charging systems work base on voltage drop of the battery, so the burden of the current draw really depends on the condition of your battery. Most batteries in good condition see very little voltage drop for short duration current draws of 60 or 120 amps for 10 to 15 seconds (full-throttle operation of e-RAM).
