Hi All
Tim wanted to know, on behalf of members how a VS works and what it does to improve a vehicle’s performance
First, this thread should be read in conjunction with this post, esp. the latter part where the various electrical demands are placed on the battery/electrical system
http://www.aussiemagna.com/forums/showpost.php?p=678064&postcount=77
Here is an explanation from a non-technical user of the VS who did his own research:
”How a ‘voltage stabilizer’ works is that it (the capacitors) can discharge at a fraction of a second, therefore supplying the very initial required current (but not more than the capacity of the charged capacitors) to the needed component, e.g. ECU, sensors, head unit, amp
etc. The main source of supply still comes from the battery.
The working principle is similar to the capacitor that's found in camera's flash unit. The capacitor needs to be charged before the flash can be fired. Without the capacitor, the battery cannot discharge at a rate that's fast enough for the flash”
He is quite close – it is the high-rate of discharge of the special capacitors that deliver the required power to the electrical circuits
I actually trialed a Jap spec VS unit to my Magna TJ2 t/tronic (3.5L with fuel rail kit and grounding kit) and found that there was smooth power delivery right through the rev range, improved torque from 1900 rpm, and the exhaust now sounds less intrusive when cruising, but still responds with a purposeful note whenever the throttle is opened
The ignition circuit benefits from reduced back EMF in the primary circuit, and the sound from your stereo system can also improve because it no longer “sees” the battery as a high frequency impedance
Cheers, Barry
