Are there any benefits to running say MSD or weapon x over stock coils? Yes? No? And why

rephrase the question to "why wouldnt you run stock coils?"
When you have that answer to the inabilities of the factory part, you will then find out what benefits you will gain from possible aftermarket parts. Yet again, my question is "why doesnt john force run cops?" ..... /thread

Good answer Duffy. Always curious to see what people think about aftermarket vs motorcraft.

ive tested accell at 6.8ish ohm and motorcraft at 5.5-5.8 but i still think the accel are junk

Aftermarket coils for modular mustangs are a waste of money as they are worth no power. On the other hand, Swapping out the spark plugs and running a smaller than stock gap is a benefit on the blown cars. On my car, at over 12 psi of boost, the spark would blow out and as a fix, the plugs were swapped to NGK Tr6 units that were 1 range colder than stock and gapped to .029. No plug will add power and certainly no aftermarket coil will ad power. The Stock Motorcraft coils on my 2001 cobra have proven to be reliable. Stock Motorcraft coils are the way to go in my opinion.

So what your saying is... They make these aftermarket coils just to steal your money? Just asking legitimately here since I think mine are shot

i ran screamon deamon coil packs on my 96 2v. no noticeable difference.
aftermarket units are plagued with quality issues (96-98) -- msd + accel.
OEM terminator cobra coils (not sure if they are the same part as 2v or N/A cobra) handle well into 5, 6, 7, 800 HP ranges... beyond that point many cobra guys swap to a traditional coil set up and ditch the COP units (99-04)

Really? No shit man... I didn't know cop's were so bad. Correct me if I'm wrong but don't the Coyotes run cop's? Why would they continue running them if they're garbage? Maybe they perfected the design? I'm clueless on this subject lol

They arent garbage, but an ignition wire setup is more reliable, andl ower cost, a cop, has better diagnostic traits and works with with modern ignitions especially with mds systems and efficency. its easier to sent a spark charge for 3" then for 8" of a plug wire.

The part # for the Treminator, 99-01 Cobra, 2003-2004 mach 1 amd Mercury mararder 4V igniniton coil is the same.
When Robert Yates racing was running a modular engine program on 24 hour endurance engines, Yates used the stock Motorcraft ignition coils. Good enough for me. Aftermarket igniton coils are snake oil.
To quote Yates on what ignition coil they used for their Ford 4V modular race engines;
"
The ignition is stock Mercury Marauder coil-on-plug "or whatever we can get our hands on." That's another way of saying most of the late-model coil-on-plug Ford ignitions are the same, so a Cobra ignition would be the same thing."

Actually yes I do. MC had me all off key there. I always thought that the cop offered better spark and what have you.
At what point in an engine build, if ever, would you replace the motorcraft with an aftermarket coil? Boost? High compression N/A? Never? Just trying to get every detail I can man. I think after this question I'll have it all figured out

i guess if 500, 600, 700, 800 hp is "so bad" lol..... and it wouldnt surprise me if the new 5.0s do run COPs. no reason not to until you hit the point where they stop working (the shop i had my car tuned at used them on 1,000 HP modulars....) -- if they work why not use them?
"so bad" and "garbage" are harsh words to use on reliable 800 HP machines. lol.

Its not about that, but its about emissions and controlability of the individual spark timing. Its 10x's more accurate with the cop then a coil and wire when your dealing with a vvt setup. If you look at most cars that run a VVT, VTECH, or MDS system they all run coil on plug set ups. These are basic engines, with basic needs.
