Had a 6AL in my Cobra and it lasted about 3000 miles. When I mentioned it on another forum I found out how many problems there are with these things. This is why you see a lot of racecars running two MSD boxes in parallel with a toggle switch to kick a new one in when one craps out.

Having said that, if you do go ahead with the MSD, as others have said - Mount it in a cool place. Good luck.

So they could crap out during a race but every team in NASCAR still runs them? Seems obvious those folks think they contribute something pretty significant to performance. Those million dollar teams would never risk failure unless there's some real return, and that's not the sponsorship money. No amount of sponsorship dollars would make up for a DNF.

I've had units crap out too, but also only after decades of use. They're especially good for engines that use a bit more oil because they've been set up loose, like race cars or aircooled cars, or because the engine has a few miles and is slightly worn, or has a great big cam. Or even just carburetors. If the car runs rich for any reason, like when you have carbs with no choke and blip the throttle to richen on warmup, or drive through big changes in altitude. Any of those scenarios and the multi spark will keep your plugs cleaner, longer times between fouling and replacement, and run better the whole time.

I've read that NASCAR specifies that teams run analog MSD ignition boxes and nothing else. Wouldn't want those boys running a digital ignition system now, would you? That recent NASCAR switch to unleaded gas was about enough high tech for this decade! (IMG:style_emoticons/default/laugh.gif)

Okay, back to the topic. (IMG:style_emoticons/default/laugh.gif)
