The Go EFI Power Adder 600HP Kit is for the enthusiast that demands more from his system or is planning a future upgrade! This system is capable of 25 lbs of Boost right out of the box and can be used in a blow thru turbo or blower application or on a single roots style supercharger. You can also run a single stage of Wet Nitrous and control your A/F as well as Ignition timing.

This system has all of the self tuning features you expect from the Go EFI systems with the extra PRO Features needed for higher output engines. Annular Swirl Discharge fuel distribution as well as Nitrous and Boost timing retard features make this a perfect choice for your Power Adder engine or your normally aspirated engine if you are considering future upgrades.

HyperFuel offers a solution to intank retrofit kits, the Hy-Fuel In-Tank Retrofit Kit. You can experience the advantage of a high-volume fuel system with the pump inside the fuel tank. This system can be used as a return or returnless system with the use of the built-in regulator. With the pump submerged in fuel, it will run quieter and last longer. With its multi-purpose ring and adjustable pump height, this is the easiest way to convert your existing or new fuel tank to an in-tank EFI fuel system. This system can be used in fuel tanks ranging in depth from 6” to 14.” Deeper tanks can be accommodated with an optional fuel pump extension kit. The In-Tank Retrofit Kit includes a 340 L/PH fuel pump and a built-in fuel pressure regulator pre-set to 58 PSI. System is suitable for up to 800 HP.
