Default High Performance Coils

Has anyone tried these new Coils?

http://www.performancedistributors.com/hemisoscoils.htm

Late model Dodge and Chrysler HEMI V8 owners can now increase performance
and improve fuel mileage through the ignition system by installing our new high
performance SOS Coils! The new SOS (Sultans Of Spark) Coils by Performance
Distributors have been designed and engineered to outperform the stock COP
(Coil Over Plug) coils. New and advanced technology has allowed us to pack
more electrifying voltage into these small coils so that the output helps you get
even more tire roasting performance out of your HEMI V8! Our SOS Coils have
increased windings to boost spark output up to 40,000 volts. That is at least a 50%
increase in spark energy over the voltage deprived stock coils! The higher voltage
along with increased spark duration allow plug gaps to be opened up to .065". This
larger gap exposes a hotter spark in the combustion chamber for an increased burn
of the fuel mixture, resulting in more horsepower and better fuel economy. Additional
benefits include quicker starting, smoother idle and greater throttle response. The
SOS Coils are designed utilizing proven technology, the same quality that has gone
into our DUI and Screamin' Demon Coils. No gimmicks are used for our coils such
as "zero resistance" or tricked out "rings", just pure hardcore ignition performance
from the leader in high performance ignition systems. The SOS coils are a direct
replacement for the factory COP coils and do not require any special modifications.
SOS Coils are covered by a one year warranty.

Not sure how well these work. I know that the MSD coil have produced no gains on your truck. From some of the stuff I have read even MSD says there are just a better quallity replacement for stock not really an upgrade in any kind of performance.

As for this brand I do know that some of their Ford stuff makes a difference. I have installed and tested it.

The biggest issue I have is how far they tell you to open the plug gap. That large of a gap on stock coils would make your truck run like crap.

I would put this at the end of my list of mods unless it can be proven to do something.

I am not feeling this one either. I'd have to see some dyno. results, along with some happy customer reviews. Only 1 year warranty? That's not very inspiring either, a product is only as good as its' warranty.

It was my understanding that a coil only produces whatever voltage needed to fire off the air/fuel mixture. In other words stock coils can produce 50K volts but if it only needs 25K volts to ignite then that is what the plug will see.

Electricity travels from the coil to the plug and voltage is dependant on resistance required to get to the ground. So if your plug needs 60k volts then the coil will produce it. Opening the gap and/or changing the air/fuel ratio will increase the voltage required but how much unburnt air/fuel if left in the cylinder with the stock setup?

I don't believe any stock engine requires any MSD/DUI or whatever other system you want. There is no need unless you increase the compression or open up the gap. Then again if the stock setup isn't burning all the fuel wouldn't the smog nazi's be after Dodge?


Someone please correct me if I'm wrong.

EXACTLY! There's little to be gained be replacing parts that perfectly adequate. Like putting a bigger fuel pump, when the stock one provides plenty of fuel already. There's no point.

I think there is a mind set about replacing the same parts a race car might need, but we don't have race cars. We don't have 12:1 compression with 15 lbs of boost that needs a much stronger coil to ignite it.

Happy w/ my 6.1/06+ dual coils w/ coil covers to conceal some of the wiring.

X2. if you were boosted and experiencing spark blowout then I'd say close up your sparkplug gaps to .035 and give it a shot otherwise you could use that cash towards a different mod.

Guys I'm not planning to install these, I stumbled across them and was simply sharing my findings. No need to talk me into or out of them.
