(* Starter Motor Excluded)

What is Accuvolt and Why Do I Need It?
Accuvolt is an active "step up" voltage regulator that takes in a vehicle's poorly regulated battery voltage, computer-processes it, and puts out higher, perfectly flat (+/- 0.01v), spike-free voltage (user-adjustable 13.5 to 16.25 volts) even when the battery runs down as low as 9.5 volts!  Once powered by Accuvolt's regulated power supply, all electrical equipment from ignitions to fuel pumps and solenoids will run noticeably more efficient and powerful, significantly lowering ETs and making all ETs much more consistent (see Guarantee Table).

Graph of Accuvolt vs Battery

   Easy to install.
   Eliminates the need for power-robbing alternators.
   Saves over half the cost and/or parts of a 16 volt system by stepping up to 16 volts (selectable) from 12 volts.
   Improves driving - no surprises - same hp, lap or pass ETs regardless if battery run-down.
   AN ABSOLUTE MUST FOR BRACKET RACERS - Most consistent ETs possible: Eliminates the largest variable causing inconsistent ETs, changing voltage, which alters the speed at which solenoids and throttle stops are activated.   Without Accuvolt, your times are affected by everything that affects voltage/charge on battery and regulator, even line loss.
   Same hp on last lap as on the first.
   Allows ignition and all pumps and on-board electrical equipment to operate at maximum consistent peak output.
   Ignition and fuel pumps at max capacity to highest rpm.
   Consistent, reliable results from on-board recording computers; eliminates all spikes and glitches, which are the largest cause of electronic equipment failure/destruction.
   An Annunciator functions as a diagnostic and warning centre for battery condition.
