Alterpower
What is Alterpower?
Alterpower will release more power from your engine resulting in increased acceleration and better response. The device easily fits any non-turbo petrol engine, and will release between 2 and 6 BHP, depending on the loading on the alternator. (Older cars with less electrical items give around 2BHP, newer cars up to 6 BHP).
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 diconnected, the alternator draws negiligible power.
Alterpower is a brand new device that fits in line with your alternator and monitors battery voltage and throttle angle, and then decides when the alternator is really needed, and when it is not.


Technical description
The Alterpower connects between the alternator and the battery. The Alterpower fits in line with the heavy duty cable bolted to the alternator.
The Alterpower is capable of switching an instantaneous current of up to 1000Amps, and a continuous current of 100Amps, more than enough for the majority of cars.
The method for detecting full throttle is a pressure sensor that monitors the vacuum in the inlet plenum and switches the Alterpower on 75% throttle openings.
At the moment a Turbo Version is not available.

Safety
The Alternator is not required all the time, an average condition battery can power a running car for at least 1/2 hour without any additional charging.
Should the battery voltage ever drop below what is acceptable for modern engines, the sophisticated electronics within the Alterpower will automatically switch the alternator back in to top up the battery.


How much power is lost from an alternator ?
The Graphs show a rolling road test of a Peugeot 205 GTi fitted with an Alterpower, both before and after. In this case the car gained 6 bhp at 5000 rpm, but more importantly the torque curve shows a healthy increase from 1200 rpm all the way to the red line.
The worst case improvement that we have seen is 2 bhp on an old car, but modern cars with many electrical accessories, especially smaller engined cars, will benefit greatly.
We are so sure that the system works, that we guarantee your car will show an increase if tested on a rolling road.
