This ignition replacement was developed over the course of one year and at the date of submission (September 2003)tested for 2 months.
Holley Strip Annihilator #800-200 Pertronix Coil 0.6 Ohms #45 MSG Vibration Isolator Mountings #8823 The big one of course is the Holley Strip Annihilator part #800-200. Holley also makes a 800-100, and 800-300. The -100 is not programable, but is cheaper and would wire up the same. The -300 is a few more bells and whistles, primarily for drag racing, not much sense in the extra cost for the Pinz. Holley is the only company that assured me these boxes would work just fine at +24vdc. All the rest Mallory, MSD, Crane, Jacobs said theirs might handle +18vdc on surge, but no more. It's pretty easy to get a stable +12vdc to power the box, it's the trigger source, or ignition voltage that's a problem. Do not even waste your time trying to mount this box without the MSD vibration isolation mounts! Holley would not recommend a coil, so a call to Pertronix got me the cross reference for the +24vdc Flame Thrower II coil. It is 0.6 ohm internal. Part number for the 0.6 is 45111, this is the +24vdc cross for the 40611 3.0 ohm coil. CAUTION!: Although the 3.0 ohm will work, it causes the Holley to draw too much amperage, resulting in premature failure of all sorts of stuff! Your Pertronix I ignitor will work, but Pertronix did caution us that it might not live as long as normal. But hey what's normal, anyway. You can use points and condenser as back up. Just connect Holley white to the points in the distributor, and there will be no red Pertronix wire. You might want shielded spade plugs for these two wires for easy replacement. You could always carry a spare Pertronix I. Pertronix also informed me that there is NO Pertronix Ignitor II, suitable for a +24vdc circuit. If Pertronix made that, there would be no risk of premature failure of the Pertronix Ignitor at all. Some other parts: Scott Ingham's (Expedition Imports) wonderful distributor cap conversion. Just remember you can't use the Pertronix 3.0 ohm coil everyone sells with this popular conversion. Plugs: Bosch 7594/W6DC civilian type, have worked the best for me. Missing from the drawing. Remember to ground the (-) side of the coil to your chassis. Improved spark can be seen at the plugs if you will add a ground strap to each cylinder head or the valve cover bolt. The (?) mark at the tach wire, is because I am still trying to find a tach that will work, might just have to provide a stable +12vdc to get a tach to work. My +24vdc tach has had no luck in a variety of hook up configurations with this box. CAUTION! CAUTION! CAUTION! Stay clear of the coil and trigger wire after installation. DO NOT go looking for a bad plug wire by running your finger along it. Discharge from the coil or plug wires is like a serious lightning bolt, and hits multiply times below 3000 rpm! At the (+, -) connections of the coil will be 525 volts, do not try to hook your tach up here anymore, or weld your fingers to the coil. Programmer must be set for 4 cylinder, 4 cycle, and set ALL the rev limiters to something above 4500 rpm's. The programmer can be disconnected from the box after programing. Some conclusions: I can easily tune my carbs for different situations, and although this is not cheap, it is far cheaper than Lastly: PROCEED AT YOUR OWN RISK! I DID COOK A FEW THINGS OVER THE LAST YEAR MESSING WITH IT! Contributed by: Jack Hotelling |
