Make a statement with a pair of matte black finished throttle bodies, feeding your 671 or 871 roots blower with this 2×4 Power Adder System. One throttle body houses the ECU, while the other secures the Idle Air Control solenoid and four more injectors. This kit supports up to 1,200 HP on a naturally-aspirated engine. This system is designed to bolt onto your dual quad or blower, then fire up with a few easy inputs through the touchscreen controller. Once started, the self-learning technology will get the engine idling and cruising well; more detailed programming can be made through the advanced pro-tuning software, including fuel and timing maps under boost or nitrous.
