I was just looking through ebay and I find this guy selling what I'll call a Super Coil. In conjuction with a Pertronix ignition, this coil is supposed to increase horsepower somewhere around 12 to 18%! He's asking $ 100.00 US for it. I asked how many volts it puts out and was answered:<br /><br />"Here are the facts: an engine only uses as much voltage as is required for the job, and most engines require about 18,000. You could run down to your local speed shop, or watch our competitor's ads, and you'll be promised the world, but it ain't gunna happen! Only enough voltage goes to the plus as the amount of resistance in the cylinder requires-period.<br />Since the PerTronix device operates instantaniously as opposed to opening a gate when using points, the energy window is increased 3 or 4 times. Our coil supplies full voltage over this entire period of time, whcih is why we call it our "long duration coil". ALL of the power in anyone's ignition system using a coil comes from the coil only, so the way something is triggered inside the distributor certainly helps in opening this window and creating reliability, etc., our coil makes a giant difference! We love the Pertronix trigger and use it quite a bit ourselves, but our coil is where the added power and economy comes from. We ask you to call these other guys and ask them just how much increase you're going to receive, and the most usual answer is "none". The attached dyno sheet, plus many hundreds of satisfied customer prove that ours does. Thanks for the inquiry, and we hope to show you soon why our motto since 1959 has been "Engines Love Us!"<br /><br />Here's the ebay ad:<br /> http://cgi.ebay.com/ws/ebayISAPI.dll?ViewItem&item=2477151031 <br /><br />Sounds like a bunch of bull. Can someone chime in on this?

If I thought I could gain HP from there coil I would have already bought it. This time I think I will stay with my everyday Super Stock coil. 20.00 to 30.00 bucks at Pep Boys.

Bondo and F_in are right, don't waste your money.

Re: Super Coil !!!??

Instead, I have purchased the Pertronix II Electronic Ignition and the Petronix II Flame Thrower II coil to replace my points and condensor for my 1986 3.0. I wasn't having any real issues with the points and condensor, but I really like the idea of not having to clean and adjust the points. I think and hope the Pertronix Electronic Ignition will make the engine a little smoother over the whole rpm range.

Re: Super Coil !!!??

Let me take a shot at this....<br /><br />The biggest problem with coils is that they take a few milliseconds to "charge" back up the primary side after being disharged. Example: If your engine has just fired on cylinder 1 and now cylinder 6 needs a spark, the primary side of the coil (12V) may not have had enough time to become fully saturated, which will cause reduced voltage in the secondary side (spark plug side). So cylinder 6 gets a weaker spark. This is really only a problem in high-reving motors where the time interval between cylinder firings is verey short. Engine manufacturers solved this problem years ago by putting individual coils on each spark plug, so each coil has plenty of time to become saturated. Also, some of the high-performance ignition companies have made coils that really do charge up faster than stock.<br /><br />An electronic trigger like the Pertronix does allow a longer duration spark, as the seller says. But the ability of the coil to use the increased duration is directly proportional to the voltage on the secondary side. So, to get the full benefit of this increased duration, you need a coil with a higher secondary voltage (40,000 to as much as 60,000V), and also a wider spark plug gap to prevent the coil from disharging too quick.<br /><br />Pertronix, Accel, Mallory, etc. sell coils that do all of this, for around $20.<br /><br />The most noticable benefit from a system like this is a quicker starting and smoother running engine. But there's no way you'll see 12-18% HP increase.

Cobra, take a look at the MSD CDI box, if you want quicker starts and more power. I have used them in hot rods and they work as advertised. MSD stands for multi spark discharge, they make them for marine applications. Go to there website and it tells all about how it works. www.msdignition.com

I would stay with a Super Stock accell, or Summit sells some pretty niffty coils that have 25% more spark then stock, but only run about 15 bucks,<br />I have coils and ingtion on my Trucks , and coil on my boat. HP gain = 1-2 , BUT you will notice a smoother running engine , Quiker starts , and a very minor fuel ecom increase. if you get the coil and ingtion , make sure the Spark plug wires are at least 8mm and the gap is set a little bigger than stock. So you can put that extra spark to work. <br /><br />good luck

$15-$30 is okay $$$$ to pay for a coil.<br />$100 is not.<br />I paid $30 for a 40,000 volt flamethrower coil at Jocko's.

Re: Super Coil !!!??

Hello, $100.00? Maybe for a coil PACK. But for a standard coil? No way! They are selling a standard part with a HUGE markup! Save the extra $$$ for gas! Up to $2.05 gal here for premimum. :eek:
