Ordered some Pulstar Pulse Plugs for the 2.4 today they expect 6 - 10 business days to arrive hope so . They claim 4 - 12 % increase in torque if so it will be noticable I will post my experiences . If someone on here has them in there N/A motor already let me know how they worked for you .

 

are they spark plugs?

 

Yeh sort of check out thier site .

 

Sounds cool

 

Those look like you would need to have perfect Timing on your car, cuz if you got any knock I think it would be more stressful on the rods and crank cuz of the amount of torque from the spark pulse. (let me know if I am wrong on this)

 

I was also looking at this but $25 a plug...dunno, I want some feedback from another member before I buy these.

 

hmm could be interesting but I too wouldn't be in the first batch to jump on this..

 

LOL OMG these are pure snake oil. First off your coils store the energy then release it to the plug...the plugs job is to distribute the charge to the cylinder. having another storage device (capacitor most likely...as it is the only thing that can store a charge in a circuit) will just delay the combustion since it has to charge and discharge...not to mention there is no charge flowing to the plug when its not firing so its not like its storing anything. the spark plug strength and fire time is controlled via the ecm with spark dwell, etc. Next they both use resistors...resistors create heat when a voltage is applied...its how they work...as long as they both have resistors they both technically "heat up ignition parts before firing" but that is the physics behind how a resistor works...they are claiming to basically have defied physics.

Now if they used less resistance in the plugs they will have decreased the heating of the components but decreased the voltage since amperage is held steady by ecm following v=i*r

Next flame front travel speed is defined by physics, not the spark strength...a better atomized mixture leads to better flame front travel...not the strength of the spark....you do need a stronger spark tho to withstand higher cylinder pressures and wetter mixtures to avoid spark blowout. These plugs provide nothing special...all they do is add what is basically a miniature duplicate ignition coil that is unpowered to your plug...probably do more harm then good.

Also our cars have coil on plug so there is virtually no components to reduce the current to the plugs.

 

$100 for spark plugs is retarded!!!

 

Yes, very expensive but it has been proven in many car mags that they realy work and dyno results as well. But I think I might stick with NGK.

 

i like my 1.99 ngk i step colder copper plugs

 

I've heard of them! keep us posted!

 

i think its been about 6-10 business days....

 

Search my threads, I made a post about these about a month ago. Everyone hatessd on the idea of them and said they'd be worthless. Looks like you have a better group of viewers this time around, lol.

Keep us posted and let us know if they actually do anything.

 

Sorry I took so long to get back I was in the Territories on a project . I have had them installed for four days throttle response is better and after averaging 12 , 80 - 120 kph runs pre plugs and 12 runs post plugs my time droped by 0.6 seconds . It was -30 c pre plugs run and -15 c post plugs I am at an elevation of about 2800 feet I want to do some more runs but we had some weather here so it will be a while before I will be able to get enough traction to do it . So far I am happy with the purchase . Fuel milage will take a while to figure but when I do I'll post my experience . Again sorry I took so long .

 

so i recomend them? im looking into them, read a ad for them in this months motor trend

bastards!!!! they make u pic up the mag to find the results.

got this from an e90 bmw forum:

Something like $25/each for the N54 engine. DSport magazine has an article that puts them around 5 or 6 HP and TQ on an Evo VS a couple of other brand new plugs - dyno'd at XS Engineering.

Hype or real gain?

Under the "torque" link on their web site, notes a raise in PSI. Is that what we'd want, esp. for a car already having an ECU mod?

 

Here are the test results. Not confirmed, I ripped it off another forum.

 

Hm, very cool. Might have to pick up a set in the future.

 

According to their website the capacitor charge only takes 2 nanoseconds or something insignificant. I read somewhere else that visually the flame front was firing at twice the rate of a standard plug, or something to that effect. I think that's the real benefit to the capacitor, not the actual wattage. Shrug, even if it does work, it's still 100 bucks.

You would think ignition is ignition. Once the air/fuel mix has detonated what more could you possibly need? It either ignites or it doesn't. And I wonder what the heat range is on these plugs. They're obviously not intended for any type of F/I. I'd like to say they're intended for old ass vehicles with horrible coil systems, so the added charge from the capacitor would help a ton, but in a G35? It's hard to argue with dyno numbers, expecially when they swapped them IN and then back OUT again, and with quality aftermarket plugs like NGK iridiums. Maybe I just can't wrap my brain around it. I don't know much about ignition systems.

 

As an "old school" mechanic, I too have to wonder about the heat range of the plug, if its a "projected tip" type, and the "gap". For high RPM firing of the plug in a forced induction or high compression engine, some performance gains (lower 1/4 milw elapsed time) can achieved by dropping a heat range or two and dropping the spark gap by .010 or .015 inch. With a smaller spark gap, the break down voltage occurs sooner, effectively advancing the spark.

Are you reading these plugs?

 

I don't know if it will harm the car or not and no I'm not recommending them , at least not at this point . I will however post what I experience with them good or bad .

 

yeah for sure, run some tests and get back to us, id like to know..also do you ever have to replace these pulse plugs?

 

No not reading them put them in because I wanted to see if they gave any gains that can be noticed , as it sits throttle response is noticable .
