Q & A

What's in the Box

If you aren't running the "little black box," you're leaving horsepower on the table. Our little black box is an alternative to running a 16-18 volt battery. The box simply increases and maintains the voltage at 17.5-17.7 volts and supplies the correct amperage at the correct rpm to give you maximum power. 

The box easily connects between your ignition switch and the battery feed wire on your HEI or MSD box. Works with MSD, Accel and other ignition systems. If not built to handle 18 volts, circuitry is protected from damage with the simple, effective and elegant use of an inline fuse.

This is not intended to be use for anything but the ignition system. You will wire this right to the ignition 12 V positive power source. All other accessories and etc. will still use the 12V power as they do currently.
