10-71 EFI INJECTOR BILLET CASE / HIGH-HELIX BILLET ROTORS (18PT.) with Fuel Rails for EV-1 Injectors
4 injector Fuel Rail on each side - holds 8 EFI injectors
This is the first ever supercharger that we’ve tailored directly for EFI. Traditionally, you would run EFI with an injector plate on top of the supercharger. Where this works, we have found increased performance by bringing the fuel injectors down into the side of the blower case. Air flows better and easier when it is dry. By injecting fuel mid way in the case, it allows dry air to more efficiently fill the rotor cavity at a higher velocity. This increase in air velocity equates to more volume, which ultimately means more boost. We are also taking advantage of the cooling effects of the fuel. The blower needs the fuel to help cool and lubricate the rotors. This new location injects the fuel right where the blower is starting to heat the air. After being subjected to Drag Week in 2019, we’ve seen that this increased volume with a cooler air charge is a “win-win” situation in the blower world resulting in a more efficient supercharger.
