Has anyone used this mod? I'm quite entertained by the idea and could possibly release a few HP at full throttle. But is it worth it? How much do you figure the gain in HP, 2HP or 10HP?


Race Marque Alterpower System

The RMS Alterpower System will release more power from your engine resulting in increased acceleration and better response. The alternator works as an electric motor in reverse, the more current is drawn, the more power is sucked from the engine. If the load is disconnected, the alternator draws negligible power. The system of disconnecting the alternator on full throttle has been used by teams in Touring cars for a number of years, and is now available for any race team or road car application.

The RMS Alterpower has very specialized current switch, capable of withstanding the high loads and damping out high current switching peaks. This is operated by some sophisticated electronics that monitor battery voltage and throttle opening, and determine when to activate the system.

The RMS Alterpower connects between your alternator and the battery. The alternator is not required all the time, an average condition battery can power a running car for 1/2 hour without any charging. Should the battery ever drop below what is acceptable for modern engines, the RMS Alterpower will automatically switch the alternator back in to top up the battery.
