That pretty much sums it up.

Every ricer will be running to get them. With there tornado, velocity stack and these plugs there gonna gain 50 whp and 10mpg.

 

personally, i think this thread is useless without an independant dyno test

 

dude, go spend $200 on them then say **** like that or

electricity is not ******* water! your analogy and rationalization is

electricity goes at one speed on a medium, whether it be copper, the spark plug wire, or the air across the gap of the spark plug. And it cannot go faster than the speed of light. Ever hear of einstein? It doesn't matter wtf you do before the electrode gap. once the voltage is high enough at the electrode the spark and all that energy will travel across the gap, it is an open ******* circuit. That's it.

And the coil doesn't dump energy gradually, you idiot. How the **** do you consider that gradual?

For the dumbass who said the spark plug acts like an extra coil pack, if you knew anything about how a coil works, you'd realize how freakin stupid that is!! Go read wikipedia!

a coil can only discharge so much energy each time it's triggered and it's based on how much power you input to the coil (voltage and current) and the size and shape of the coil and how it manages the magnetic field it creates. It does not create power, it only changes the voltage. It's a transformer. If you input 15 volts and 10 amps into the coil, that's 150 watts. Even if the damn thing was 100% efficient and that 150 watts made it to the spark at the plug electrode (pulstar says on average it's only 25 watts), how the **** is the spark plug going to generate 999850 watts to make a 1 million watt spark?
1 watt of power per second = 1 joule of energy. The time the spark happens is fixed, you cannot make it happen faster and have a smaller number for time on that side of the equation and then say you have more watts. It doesn't work like that. Read a book on electricity or electronics. start with v=ir. then when you go "but 1FMF...." go stick your finger in a wall socket, that's 120 volts at 20amp max because your breaker in the fuse box should be 20 amp, hopefully it's 20 and not 15 amp breaker because I want the max current to flow. Barring loss in the wire and the resistance of your skin, it'll be 2400 watts hopefully shocking some intelligence into you. If you have any common sense, you'll know that'll happen in less than a second, but lets say it does take exactly 1 second, then that's 2400 joules of energy. Hopefully you can hold on for 10 seconds before you croak, that'll be 24000 joules.

do you have electricity at your house? How many kilowatt-hours you using per day? Say your a pig at 1000 kwh per month, that's 33 kwh per day. I'll use 40 kwh per day. 1 kwh = 3600 joules. 40 kwh = 144000 joules.

you say one thousand kilojoules, that's a million. So your spark plug fires with almost 10x more energy than your house uses in a whole freaking day?

 

**** i screwed up on the numbers comparing daily usage to your home, it's 1 watt-hour = 3600 J. 1 kwh = 3600000 Joules, so instead of 10x more energy per day, each plug firing would be like 1/4 the daily power usage of you home.

it was funnier the other way, but then my number's would be like pulstar's numbers and I'd have to kill myself.

 

It's just condensing the energy before it releases it - It's just a refinement, why is that hard to believe?

 

Because they are making claims that are untrue, period. It can not is any way make mroe power than it being put into it and they are 100% claiming that it does

 

so by the time the plug build up all that power, i would think that it could have already sparked, cuase it still has to wait on the coil to release all the energy so all your geting is a more powerfull spark but it not going to be as fast as if the spark plug sparked as soon as it got some juice

 

those plugs might make that much power if the hooked them up to the hover damn

 

It just seems to me that if they were making those claims, and not a bit of truth to them - there would be a lawsuit. Pulse energy may not make your car an instant hot rod, but even with the test they were required to put it through shows that. Some one mentioned that the coil pack is a transformer, which steps electrical current up or down depending on the windings - I'm not an electrical engineer but i wouldn't be so quick to call BS. If nothing else it seems like a fair attempt to reduce the amount of unburnt fuel in the exhaust. It takes advantage of smaller components build within the plug that allow it to effectively store up and rapidly release energy in one quick burst - that's what pulse capacitors do.

 

they can make those claims becuase ther not saying what is powering the spark plug to make that kind of power, it like heads,LT,cams they tune the car for peak power and have the bolt ons to make max power for that part, then they claim that a cam = 60 or LT = 50 hp and on top of that most time that to the flywheel

 

you also need to learn the difference between volts and watts. The claims is that the plug creates a 1 million VOLT spark, not 1 million watts.

Voltage = the ability to overcome resistance. The higher the voltage, the easier the electricity can travel through the ignition system and cross the gap in the plug. The easier electricity can travel, the faster it can travel. Electricity cannot travel faster than light, you are correct. But electricity traveling through copper is not traveling at the speed of light.

 

oh contrair mon frair:
it was 1 million watts they are claiming,

i have an electrical engineering background, that's why i'm about it especially when people try to support it with their own claim of electrical understanding. Fact is, watt is unit of power, and I hoped to have described amounts of power that could be understood but everybody wants to believe there is some truth in this marketing claim.
they are playing on your ignorance, twisting technical knowledge in a range of ignorance which many people have, to sell their product. And because it cannot be easily disproved, or better said there's a window of opportunity for it to be true because most people don't have technical knowledge regarding it, they fall for it because that's the way people are- they will hope for it to be true rather than dismiss it as false.



What is condensing energy? It's hard to believe because I don't understand it, and I like to think I know electricity. I've studied enough about it and have somewhat of a career around it. You don't condense electricity like you condense water vapor back into liquid. What is condensing electricity?


you're very naive and foolish if you think fear of lawsuits will keep the marketplace honest. That is so far from reality. It's all about money! They could claim 1.21 jigawatts of power, ain't nobody going to sue them. It would cost to much to sue and what reward is there? Nobody gonna pay $10,000+ for a lawsuit just to disprove a marketing claim. There is no damage done, and in fact their claim is "up to 1 million watts of power". That's there out if anything, key words "up to".

this is not entirely true and largely out of context concerning the subject. Yes, electricity will never go faster than light, and most times it is much slower than the speed of light, it depends on the medium like i had said. But higher voltage does not mean electricity will travel easier resulting in it travelling faster. Resistance is what determines "how easy" "electrical current" can travel through a medium. But you have to watch your vocabulary and define what you mean by electricity. In this case it's the movement of electrons across a conductor, then across an airspace which is different. You get into electric fields, ionization, a bunch of physics I don't care to understand and won't say that i will. But I seriously doubt it will speed up the flow off energy. Even if it did, it's irrelevant. They say the pulse circuit accumulates energy, so where does it come from? It's a bogus claim.

Here is pulstar's explanation from their site:

 

so there trying to say that all the heat created by the spark that only last for 30 millionths of a second is stored to create 1 million watts. im sure there no where near enough energy wasted by that small amount of heat to create 1 million watts let alone a 100

 

In theory it's cool, It is just a capacitor built into the plug itself - which simply store up the entirety of the energy from the coils then releases all of it at once. By the looks of what i've read....it seems like there is some other variable in the way the consider it a "1 million watt" plug - maybe they are measuring light intensity? 50 watts of light intensity would seem about right for the light a spark plug puts off, while something white hot like the "1 million watt" pulse could i suppose be 1 million watts of light intensity - sort of like the measurement of those 1 million candlepower torch lights? Just a thought.

I also read of people using capacitors inline before the spark plugs to achieve a similar effect, as well as hearing about nology plug wires. Not a HUGE performance gain, but possibly response and emissions conscious.

"Spark plugs waste energy by heating ignition components before the spark occurs. Pulse plugs capture wasted energy with a pulse circuit and then release the captured energy into and beyond the spark gap. When the ignition power overcomes the resistance in the spark gap, the pulse circuit discharges all of its accumulated power - 1 million watts - in 2 billionths of a second!"

This is why theory and adding complexity to simple things is a never ending battle.

 

OK I found some evidence so we can kill this thread:

Looks like they ARE comparing light intensity and not the actual ELECTRICAL pulse, the EPA also found a meager 2.7% increase in fuel mileage - that could be from a simple real world variable like a headwind in one test LOL.

What makes Pulstar different from spark plugs is its built-in capacitor, which stores the ignition’s electrical power and then discharges it in an intense plasma ball. Pulstar is capable of delivering up to 10,000 times the power of an average spark plug, which translates into greater fuel efficiency, increased torque and horsepower and reduced hydrocarbon emissions. In fact, spark plugs can be compared to the LOW-POWER output of a FLASHLIGHT, while pulse plugs generate intense power like the BRIGHTNESS emitted from a camera’s flash bulb.
—Daniel Parker, ENERPULSE CEO

 

I actually came up with the same explanation...

I still don't believe their BS claims of power though. But I do believe that is how it works, I just don't see a big hp gain.

 

This is how I understand it. The spark IGNITES the fuel mixture; it doesn't BURN it. The system needs only enough spark to create IGNITION. A hotter spark doesn't create "greater" ignition, nor does it burn the mixture faster or more thoroughly. The only amount of spark needed is the amount to create ignition. Automotive engineers understand what they're doing and specify plugs that will create proper ignition for a given application.

Going back to old school, it's like the guys who replaced their points style ignitions with "hot coils" or HEI's, thinking it would make "more power" because the spark is "hotter." There may be other benefits, but more power isn't one of them.

Correct me if and explain why I am wrong ...

Dyno tests were done on corvette forum months ago....they compared Pulstar to NGK 55 and saw that the Pulstar plugs sped up the burn like they stated but in the higher compression LS motors it caused knock and therefore timing retard....read for yourself, test was done at a sponsers shop here in Tampa.

 

the hotter spark makes the flame front propogate faster through the cylinder. the higher temperature spark creates a higher temperature burn, the higher the temperatures on the perimeter of the flame front, the faster it spreads.

 

hahahahahahahaha

great f'ing dyno report, reading page 1 of that thread a 2006 bone stock C6 corvette only puts down 306 rwhp then 313 rwhp with pulstar plugs

my 2002 ss stock put down 328 rwhp last year when i dyno'd it, that's an LS1 comparing to what an LS2? something's not right, that dyno don't mean jack.

furthermore, almost all latter dyno pulls will always show higher numbers because all the fluids are hotter (engine oil, transmission, differential) and with lower viscosity you will dyno slightly higher numbers. I did 5 pulls with my car, with 10-15 minutes wait in between but with the car still running. I have an oil temp gauge, running 5w-40 oil my 4th and 5th pull were the highest, and that was when my engine oil temps were 220F, versus starting at around 180F oil temp on pull #1. Way too many variables with everybody's dyno tests! Nobody controls anything! If they do a baseline pull with pulstar then swap in some cheapo champion plugs you will most likely put down higher dyno numbers on the champions.

The spark knock, if it really was caused by the pulstar plug, is probably due to it's heat range being hotter than the oem plug. BUT, it's a head/cam car, all the knock problems are probably because of the tune (when are they never?) if not the parts on the car. How are you to know? Use a stock car that hasn't been modified or tuned so can be sure of reliable performance! Read further down in that thread and you'll see posts of how the dyno numbers are worthless.


REVGTO makes a very good point, the spark doesn't do the work, the expansion of gas from the combustion of fuel does, look at the big picture. Once the spark is sufficient enough, anymore power in the spark isn't going to result in more power from combustion. That spark always happens at the same point in space and combustion (flame front whatever buzz word you want to use to complicate the issue with) always happens the same. What influences combustion is temperature within the cylinder, a/f mixture, how homogenous the mix is, and cylinder head/piston design. Actually what influences things the most is what fuel you burn, and what cylinder pressures you have! The spark plug is a waste of money, but they will always market on the idea of a hotter spark = more power, hot = power, hot = energy and people through ignorance will agree with that. And if it's advertised and they have a whole website with all these test, how could any of it not be true
