  • Revolutionary new nozzle design that provides fantastic atomization characteristics at all flows
  • Rust proof nozzle made of 316 Stainless Steel with no internal moving parts
  • 100% Water Compatible
  • Adjustable Injection Flow – Flow adjustment is as simple as adjusting a knob
  • Variable Flow Controller that can change injection quantities based on different parameters
  • Uses high quality compression fittings
  • Universal fitment
  • Designed and tested on our in house test bench
  • Each system is quality checked
  • USA Made and Family Owned

Product Options:

  • Nozzle Style
    Low Flow
    Max flow is adjustable from 40 to 120 ml/min
    Standard Flow
    Max flow is adjustable from 100 to 300 ml/min
  • Nozzle Quantity
    x1     One Nozzle of the Selected Flow
    x2     Two Nozzles of the Selected Flow
    *need x2 1/8 NPT injection ports for 2 nozzles
  • Compression Fittings
    Standard Brass Compression Fittings
    316 Stainless Steel
    All Compression Fittings Are Higher Quality and Corrosion Resistant
  • Methanol Tank
    Standard Tank (3 qt)
    3 Quarts in Volume
    High Volume Tank (2.5 gal)
    2.5 Gallons in Volume
  • Controller
    Standard Controller
    The HPC methanol injection controller provides variable flow rate control using the vehicles MAP sensor voltage as an input. Includes low fluid level detection and the ability to prime the system with a button on the front face. The controller may also be used as a simple on/off control for those that do not desire variable flow rate but want the convenience of in-cabin and on-the-fly control. Comes standard with the 29 psi (2 bar) MAP sensor setup. Available also is a setup for 2.5 and 3 bar MAP sensors as well as a 2-5 volt universal model. Please ask for details if interested in alternate options.

    Standard Controller w/ Liquid Level Sensor

    Standard (HPC) controller comes with liquid level sensor for water/methanol tank.
    Upgraded Controller
    The SIHRC Cortex EBC provides 3D map injection points with multiple inputs such as MAP, RPM, and Throttle Position. With better PWM output, it can be used to control the pump at lower outputs which increases the injection range. Includes low fluid level detection and the ability to prime the system with a button on the front face. Utilizes an internal pressure sensor with a digital display. Can be integrated with failsafe controls. Aside from being a methanol injection controller, it also has other features such as being able to control turbocharger boost based on gear, RPM, vehicle speed, throttle position, or time. Use two auxilary PWM outputs to control water/methanol systems, nitrous systems, or even transbrake bumps.
    *Can not be used w/ Liquid Level Sensor
