Overview:

Take your forced induction ride to the next level with a Holley water/meth injection system! Integrated into the Holley HP and Dominator EFI Systems is the capability to control water/methanol injection, allowing you to safely run on lower octane pump gas! What makes the Holley water/methanol system unique and light years ahead of competitive systems, is that the solenoid flow has been characterized within the ECU. Program in an exact flow amount into the software, and that flow is injected into the engine. This is critical to ensure that neither too little (causing engine damage), nor too much (causing a large loss in power) water/methanol mix is injected into the engine. Select the exact percentage of water/methanol mix to be delivered vs. the percentage of fuel flow present, at any RPM and load. This makes tuning a very simple and accurate process. All components are designed to be compatible with water/methanol mix of up to 50% methanol. The Water/Meth solenoids are run by an injector driver output. If an extra output is not available (as would be the case on a HP ECU driving 8 injectors), PN 554-115 can be purchased that can be driven by a low side PWM output.

    25 lb hanger doesn’t hold my Echo trimmer
    Size: 4" - Red, Style: Open Hooks, Size: 4" - Red, Style: Open Hooks
    Purchased the holders for my Echo trimmer and hedger but the tines are not long enough to hold the Echos. A picture in the description shows a gas powered unit hanging which is why I bought the hangers. Buy the larger 45 lb hanger for trimmers. Nice hook but I’ll probably send them back if i can’t find a use for them soon.

    Handy
    Size: 4" - Black, Style: Open Hooks
    I use an ocean container for storage and have some things that need to be hanging. These are perfect for any place you are unable to drive nails. I bought the stronger ones and have had no problems. Ordered more after trying them.

    These are a good choice
    Color: Black-2 Set
    These are great. They are made well, look nice and are easy to move when I’m dusting. I use these to keep perfumes, lotions and vitamins organized atop my dresser. The velvety compartments are a well sized and the layout is conducive to storing the kind of objects women or men typically store atop a dresser. I find these bins quite functional. I feel like these were a good value. They weren’t the cheapest and they weren’t the most expensive. They look nice and feel high quality enough.
