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.

    Dry mouth is miserable.
    Size: 27 Count (Pack of 1)
    The mouth lozenges for dry mouth were excellent at first, but I have dry mouth all day, and they started upsetting my stomach. I guess I was taking too many. Since I switched to the spry, I don't have a problem. I keep the a small bottle of the spray in my pocketbook, because I need it sporadically. It is probably different with each individual.

    A Great Product!
    These tablets are inspired! I use them every night with my cpap. The back of each tablet has a coating that, when moistened, is easily glued to a back tooth to slowly dissolve while sleeping. Works like a charm! These would be good to use when speaking publicly, too - no more performance dry mouth. You really can't tell it's there once it's glued in. The minty flavor is there, but not overwhelming. I am never without my Xylimelts!
