Dyno testing of various deloreans also revealed that the ignition system is weak, especially are higher rpms. The MSD ignition upgrade and the performance increases it something that Steven Wynn is also investigating on his higher HP engine. This upgrade can be made without altering your vehicle. You can always put the stock equipment back on for shows. I used an MSD ignition set ups on the 97 DeLorean V-8 and my other performance cars and it does make a difference you can feel. Why is the MSD better than stock, because it fires the spark plug 4 times in a row. This way you have not chance of misfire at any time, even with lean mixtures. Some people have a concern about premature spark plug wear due to this multiple spark discharge (MSD get it?). I have never experience premature spark plug wear on my cars. Bob Brandys #4675
