Overview:

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD Flying Magnet Crank Trigger system does exactly that by using four magnets embedded in an aluminum wheel. Although similar in appearance to other crank triggers, the MSD Flying Magnet design works on a different principle. Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This ""flying magnet"" design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each Flying Magnet Crank Trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver's side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The CNC-machined aluminum bracket securely holds the pick-up in place and is slotted to provide a wide range of timing adjustment. Spacers are included so you can mount the bracket on engines with standard motor mounts or engines with a .25"" motor plate. These systems will trigger MSD 6, 7 and 8 Series Ignitions and all MSD Timing Accessories.

    Good Results
    I am not a doctor, but I can attest that Qunol Brain Health Focus Plus is working for me. I must confess that I am no spring chicken and was experiencing memory problems that go along with aging. Furthermore, my doctor has me wearing an oxygen tube, and I was worrying about what happens to my brain when something goes haywire in that department. I began to search for an OTC product that might help and noticed that the claims of one product widely advertised on TV were not supported by research while Qunol does have scientific support. I've used the product for several months now and have indeed noticed a decrease in my symptoms. I feel confident recommending the product to others in the same situation.

    Useless
    Of all the supplements I've tried, this was the biggest waste of money. I just finished the bottle and honestly can say I gave it a good shot, but really it is as useless for memory as a multivitamin would be. Furthermore so expensive and each dose is 2 hard white pills. I've been using brain supplements since college and literally this is useless.

    It works
    This kind of product is always hard to rate, Does it work, or doesn't it. Am I aware of having it onboard, or is it my hopeful imagination? Who knows? But for both of us, I feel as though I am more aware in general but most important to me is that I have more energy to accomplish things. Does a more active brain lead to more physical stamina? I don't know, but I do know what I feel and it is great for both us 70++ year olds.

    Another of Hayes’ incredible tools for healing
    Format: Paperback
    Incredibly informative! I have followed Dave Hayes for years. Much of what he refers to in this book is familiar particularly the concept of controlling your own well being through Jesus and our Heavenly Father. I am delighted with Hayes’ ability to break down the often nebulous and overlapping states of being that we should be able to perceive but often cannot, enabling us to change and heal. Another bravo to this practical, articulate, generous Christian author anchoring it all in the Word.

    Excellent Knowledge on spiritual warfare.
    This book is Great Educational Material if your willing (Especially as a Christian) to fight in the daily spiritual warfare. It shows you how to spot the invisible enemy that tries to Seek, Kill & Destroys lives. Praying Medic's Books are Excellent! Also bought his other books the Lord said to buy his book on Healing. Thus saith the Lord, "My people are destroyed because of LACK of KNOWLEDGE."
