HI, I have 4 REALLY old C.D.I units from 1968. Its called a MARK TEN B and They where made buy a company called Delta. They where sold as a kit. From what the manual says it will run a lower voltage thru the points ( last 3 times as long ) and give a hotter and more precise spark from the stock coil. with a stock coil (150:1?) it will deliver 50KV to the spark plugs. I plan on running one for the leading and one for the trailing. Just wanted to see if any one else has herd of these units or something similar. I have one in my 71 bug now and it works great! Smother idle + more power too!

Thanks

Is some one making somthing like this now?? M.S.D???

The world has turned many times since the "points" triggered system was king.



The constantly changing values and lack of accuracy of the points system doomed them once electronic trigger systems became the norm.



You might put one of those systems on a scope to see what input voltage the coil will see. If there is over 100 volts available at the coil and the system can be triggered by a optical or magnetic pickup then it might be worth the time to install one.



The MSD consumes about one amp per thousand RPM. It operates the coil primary at 350 to 400 volts depending on model. At low speeds the plug will be fired 40 times in each cycle. So, the MSD will fire fouled and oil covered plugs with ease. Starting in cold weather is much improved. Firing over rich and over lean mixtures is easy with the MSD.



Every Grand National car, and every SCCA Mazda rotary I have seen is so equipped. I would not consider attempting to race without two units in a rotary. MSD-6AL if you need rev control (a real good idea).
