Tell Me About Coils
ORIGINAL: turkeyhunter1962
I've installed the entire MSD 6A ignition system and Blaster2 coil in my 01 Ram. Extremely easy. The System and coil work together to provide multiple sparks to each spark plug at lower RPM's and one full spark at higher RPM's. Stock ignition systems are not as efficient as this upgrade. The stock system always sends one spark to each plug. At high RPM's the stock coil may not fully recharge between firings resuting in a lower voltage spark across the spark plug reducing the efficiency of your fuel burn.
Just by adding the Blaster2 coil you will provide a full spark at low and high RPM's for your engine. The MSD Ignition System is what tells your coil to send multiple sparks at low RPM's.
I've attached some pictures of my install here.

I believe you've followed the saga of my truck. Would I benefit from this type of bad-*** setup? Remember, but truck is for hauling cargo, not for hauling ***

My truck has been built for hauling also. I pull a 7800 pound fifth wheel a couple times per month and am always hauling 2000 to 2500 pounds of something. Based on my usage of the system, I think just about anybody would appreciate the greater fuel burn efficiency provided by this or a similar setup.

Had a tranny problem myself earlier this spring and upgraded to a performance 46re from Dr. Evil out of Chicago. http://www.dreviltransmissions.com/home.html
I bought the Pure Evil tranny with the extra deep oil pan and red line oils. He included a brand new tranny cooler. Between the day I ordered it and received it was about 1 week. I spoke with Billy (the owner of Roadmaster transmission and the real Dr. Evil) and he is the most knowledgable person on trannies I have ever met. Including shipping to Minneapolis (picked up at the freight terminal), I think I paid about $2400 total. So far no issues at all with the tranny. If I had to do it over again, I would probably ask him to tone down the shift kit just a little bit, but I'm getting used to it now.

so is what your saying is the blaster 3 coil is a better coil for these trucks and it can work by its self OR with the 6A box....so can i just put in the blaster 3 then upgrade and add the 6A box when i have some more funds (ive over spent my "truck alowence alredy")
Ryan,
Yes that is what we are saying. Make sure that you decide which Ignition system you want to purchase in the future. Then purchase the Blaster coil that works with that one. The install of the coil is very straight forward - two wires. Although you will have to fabricate some way of mounting the new coil. Indy Ram man and I had differenet methods, but we both achieved the same results.

I think Accel makes a quick release harness that will work with MSD coils. I believe I read it ina post that Shott made when he dumped a $1000 into his truck during one week.

I have "borrowed" the Accel and MSD replacement coils for 5.2/5.8 engines
and bought the Crane Lx92 coil and Echilin replacement coils
for my 1995 Magnum 5.9 V8
and run them all for several days.
The MSD coil was used for several months with Champion RC12YC, Autolite 3923, NGK V Power and Bosch Super+4 sparkplugs and compared against the factory coil.
I could find no advantage to any replacement coil,
and the Crane LX series coil ran rough.
There have been many posts where the Accel direct replacement coil for Magnum engines has failed in service with little warning before hand.
Do a search and I have posted a lot of technical type measurements on these coils.
All these coils (except the Crane)
have turns ratios around 72
and I suspect that if you keep your sparkplugs with sharp edges
a coil with a turns ratio about 60
might improve the 'burn time' without causing misfire at high rpm.
Most modern engines have gone to 'coil on plug' like the 4.7 and 5.7
and most of these coils drop down in turns ratio
to get a longer burn time.
It is worthwhile noting that the US Patents on MSD style multi strike ignition expired long ago...any automaker could use this style now...but none does.
The clear ignition system favorites
among automakers seems to be
low turns ratio coil on plug,
two sparkplugs per cylinder (Dodge+Mercedes+Ford 4 cyl+Nissan 4 cyl+Alfa)
and
iridium alloy sparkplugs with extra sharp tips
Electromotive does make a coil on plug retro-fit kit
for V8 engines that originally had distributors

What about the Crane Ignition System Hi-6 CD system? it says its plug n play.
"Twice the spark of other ignitions.
When Crane tested its new HI-6 ignitions (with optional PS-91 coils Turns Ratio: 54:1 ), they produced twice the ignition energy of a leading competitor's boxes. They're designed to work with engines from 10:1 to 14.5:1 compression ratios, nitrous, superchargers, or turbos. Made for street and racing use, they come with Crane's "Plug-n-Go" universal harness to cover most installations, with optional harnesses available separately. Their built-in rev limiter automatically drops cylinders in firing order to prevent fuel loading, and is adjustable by increments of 100 from 600-9,900 rpm without any chips. Other built-in features include a tach accuracy check, a system problems check for easy problem diagnosis, and crossfire protection for supercharged and turbo applications. They feature solid-state construction that's immune to vibration and shock, and an anodized heat-sink shell for reliability. Crane also offers them in Import Power versions that have the same features and are available in 4 different colors. They're compatible with points and electronic ignitions and work with 4, 6, and 8-cylinder engines with distributors. "

well, offhand the magnum engine runs at a sloppy 9:1 compression ratio.
I like the 4 different available colors, though. You should probably call support and ask if the system will work at that compression ratio, or better yet, why it won't work at that compression ratio.
