Introducing the newest development from the Holley EFI engineering team, our EFI high flow dual port boost control kit featuring two solenoids. This kit contains a set of pre-installed high flow solenoids, which feature a dual O-ring sealing design, preventing any boost leaks out of the manifold. The solenoids are driven by Pulse Width Modulated (PWM) outputs of the ECU.

Features:

  • Black anodized billet dual port manifold with built in mounting provisions
  • Two 1/4” NPT Push-Lock Fittings for easy plumbing and installation
  • Two pre-terminated connectors simply plug into the solenoids and extra pins into Holley EFI ECU connectors
  • Proprietary design to flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids

When selecting solenoid configuration in the Holley EFI software, use the Dual Holley drop down selection. It is not advised to use the PWM+ outputs on an HP ECU, but rather use the PWM- Outputs. If you have a Dominator ECU, either use the PWM- outputs, or use a PWM+ output on the J2B connector.
