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.

    A Game-Changer: Camco Deluxe Poop Tote Review
    Size: 36 Gallon, Style: Heavy Duty (2 Wheel)
    The Camco Deluxe Poop Tote is a standout choice in the market, offering exceptional build quality, comprehensive features, and impressive functionality. What sets it apart is not just its superior design but also its surprisingly affordable price tag. As someone who previously owned a Thetford unit, I can attest to the significant difference in quality. The Thetford unit, while well-made, fell short in design by lacking a crucial component - the drain valve for the tote. Even after investing in the missing part separately, using it remained a source of frustration due to its flawed design.In stark contrast, the Camco Deluxe Poop Tote comes fully equipped with a well-thought-out design that prioritizes practical real-world usage. One particularly thoughtful feature is the inclusion of front wheels, which make a noticeable difference, especially for older users. These wheels significantly reduce the effort required to pull the cart towards your tow vehicle, enhancing the overall user experience.

    Well made and useful. Wish the handle was more comfortable though
    Size: 21 Gallon, Style: Heavy Duty (2 Wheel)
    Like most people I am using this tote to unload my camper’s grey water tank while camping. It is well made and good quality and has worked very well. They also provide all of the fittings you might need. The only thing I don’t like is the main orange handle. The front side it solid but the backside is ribbed or hollow. When the tank is full, and I use the handle, the ribbed side kinda hurts my hand. A work glove solves this issue though but I wish the handle was solid.

    Sturdy portable tank
    Size: 15 Gallon, Style: Heavy Duty (2 Wheel)
    Strong portable waste tank. It is pretty tall (about 12 inches plus the height of the elbow). I had to raise my trailer jack most of the way up to raise the waste outlet high enough to facilitate draining. Once I figured that out, it works like a champ. The large wheels really help with transporting the full tank across my yard. Camco has included all the accessories needed to complete the job. The 15 gal capacity is pretty small...so you may have to split your job into multiple trips, but for as often as I might need it, it'll do.
