DUI-5577-102 GM LS Mini-VIP Coil Enhancers
The LS-1 Engine has eight ignition coils, one for each cylinder. As with most ignition systems, these coils are powered by a 12 volt hot wire. Performance Distributors has designed the new Mini-VIP to send 18 volts into each coil in order to improve performance, power, and tuning abilities.
Two Mini-VIP's will be required for the LS-1 as it has four coils mounted on each side of the engine. The voltage for each set of four coils is supplied by its own separate power wire and the Mini-VIP installs directly inline with each of these wires.
Most electronic ignitions like a lot of voltage and the 18 volt Mini-VIP will enhance the LS-1's ignition system by allowing spark plug gaps to be opened up to .075". The larger gap burns the fuel more completely on each piston stroke which may allow you to run a richer fuel mixture and that will make more horsepower.
Also, the Mini-VIP prevents voltage drop at the coils which is commonly experienced when accessories are turned on. When the voltage drops, the spark at the plug deteriorates significantly. The 18 volts from the Mini-VIP not only cures this, but the addtional spark intensity will improve performance and keep the spark plugs cleaner, longer.
