420A MSD coil and wires?

[ramsack]

Coppers only make sense to stay with in a turbo engine...hot spots on the plug itself. Platinum will last much longer for a non-turbo engine. But yea, get rid of the 4-electrode crap. The spark has to decide which electrode to jump to each time. Each time a spark happens it keeps the metal where it strikes clean, and each time combustion occurs it dirties metal that wasn't sparked upon, so you have 3 electrodes constantly getting dirtier, making them last not as long, weakening the spark. A single electrode is going to spark pretty much in the same place every time. Even so a 4-electrode plug should go to only one electrode its whole life because it will go to the closest one, down to the molecular scale. I doubt they are gapping their electrodes with an electron microscope.

soo...Screaming Demon is the best one??? they claim to have 40,000 Volts Vs stock 36,000 but what about the resistance??

 

[ramsack]

Why are you non-turbo people looking for more spark voltages and low resistance wires? It's a waste of money and an air fuel mixture either ignites or it doesn't. You need something like a CDI to actually make use of a nice coil and some thick wires, otherwise it's still an inductive system and using low-resistance wires and/or a crazy coil is just going to do nothing or even hurt ignition performance. You only need to worry about upgrading ignition if you are blowing out spark, which is not going to happen on gasoline, stock or non-crazy compression ratio, or boost.

Just to add to this thread about MSD, not sure if it is going to be related to the specific coils that your using for DSM's but in my offroad experiences with my bronco and many others broncos we have had great success with the MSD TFI blaster coils that are made for the TFI ignition systems in the early model FI systems on fords. What thsi is called is the "six liter tune up" What you replace is rotor, cap, coil, plugs and wires. coil was MSD TFI blaster, wires were bumped from 7.5mm to 8.5-9mm depending on brand you bought and plugs were some autolite coppers. We opened the gap (i know this is opposite of forced induction) and bumped up the spark delivered and advanced timing a bit. This helped out with a lil more power, better idle, breakup at high rpms, and mpgs. And no this isnt based off of changing an old coil to a new one, many ppl have went from brand new OEM coils to doing this and seen increases in all of the above. gapping them and timing was tried with OEM stuff that was also new and had break up at high rpm and didnt run as smooth due to the gap. Just my .02. If you gues want to check out some threads on it head over to FSB and search "six liter tune up"

Stay away from obx, 99% of there parts are crap, they have very little quality control. I got an msd coil pack, ran amazing for about a year then died, imo a new part that only lasts a year is crap, I've been running a Howell Screaming Demon coil since then.

@420arunner, please get rid of those platinum plugs, your car will run much better with coppers. The platinum's are known to cause problems with our engines because they are a colder heat range.

Mine have a higher heat range than iridium plugs

No im sure they arent, but it sparks to all 4 electrodes at the same time and the plugs reach their self - cleaning temperature seconds after you start the engine none of my plugs get dirty

It starts better with the new wires and ive noticed slight improvement in mid to high range rpm but yea i know they're for higher horsepower engines but thats what my ultimate goal is

 

[ramsack]

Well a spark is going to follow the path of least resistance, so it will only spark to one electrode at a time. I don't mean the whole plug being clean. When a spark hits metal it cleans oxides off its surface by explosion. You can see this if you take a piece of shiny metal, some wires, and a battery, and create a short on the metal with some sparks. Though a high voltage spark isn't going to pit the metal like a high-current battery will. I can definitely see it starting better with higher voltage, as cars are pig rich when they are starting, so I stand corrected about that.

420arunner, it sounds like you're getting all of your information straight from the marketing departments at MSD or OBX. Listen to ramsack, the ignition system is one of the last things you'll ever need to upgrade. A stock coil, wires and plugs will take you far. Most of these other components are gimmicks.

You can install MSD/OBX Coils just because they look good, but NO performance gains out of them (I have MSD coil and it looks great)

you mean cause its red?

YEAH, check out my engine bay

i need your ecu holding bracket. btw what spark plug wires are those?

hahahaha, my ecu´s bracket is the OEM painted same color with the valve cover using HI temp Paint, and the wires are "XTune 7 Core " 10.5 mm

I Need your ECU

The msd coil its just like paul said, a low qc replacement. The best bolt on coil is the screaming demon. Once I get my car going again I plan to check into a few more avenues before doing something like cop with symtechs system (one that actually charges the coil properly and not do worse) the stock coil its good until your over 400.

 

[crazyboy81]

my bad. i had to leave so i typed everything and just sent and now im back.

1 more question: which spark plugs would you suggest and how much to gap them?

I bought the Walmart sold Champion plugs "copper core" because I planned on seafoaming soon and they were cheap, plus I had a NGK missfiring in #2. I was gapped on the NGKs at .048 after trying out different gaps. Long story short: champions gapped at .040 makes my car run so smooth and it raised my gas mileage.

This thread makes me

MSD is usually a quality product. When it came to the 420a's R&D, MSD failed horribly. They basically pulled an OBX and didn't do ANY R&D and came up with a product that, as Sean said it, is not worth the money if the average consumer is only getting a year out of the product. If you want better a better product get a Screamin' Demon or Granatelli. For wires get Granatelli. Period. There will be little to no performance gain.

If you want performance, retrofit a Plasma Spark COP or get a real set of aftermarket coils and get a tunable ECU. Expecting performance gains from an ignition system with a stock ECU still giving the instructions is like expecting to understand Hellen Keller if you give her a Bullhorn... You can't change your spark tables. It'll be the same message, just louder..."HRMNFAHH GLACKBUUUUURRDPINGAAAAA!!!!!"

I'd agree with the MSD failing horribly on those coils. They basically bought a coil from one of the big coil manufacturers, and that coil has worse specs than stock. Even aside from its problem with not lasting, it just isn't a good match to the OEM system. Judging by the specs, OBX bought that same one, don't know if they bought it from MSD, or the company that MSD sourced it from.

I don't know that I'd agree that most of MSDs stuff is quality. They have a real mix of decent, and gimmicks. Even their display that they use to show off their products is rigged to artificially make their box look better.

And I certainly wouldn't agree about using any of those Plasma setups. 99% of what I have seen from them is snake oil. Multisparking an inductive spark? Haha.
