Pulstar Plugs
 
Any body heard of them?

http://www.pulstarplug.com/index.html

Debate away guys. ;)

There is no performance to be gained by any plug unless you are running the wrong plug or wrong gap. Any website that has to be that flashy trying to push a product is clearing trying to just make a sale.

What kind of car are you using this in? If your supercharged you will have to watch your heat range. Not sure what year you have, but for my year the AD-1 looks like it will work. But I can't seem to find a heat range. If boosted you shoudl be 1 or 2 ranges colder depending on your boost level. Also, if your boosted, you dont want platnem, you need copper. I can't seem to find this information on the site. Perhaps I'm just not looking right.

Also, I agree with the other message, can't see how a plug can make a huge difference, coils yes, but plugs?

I wasn't asking about using them, just as a general concept. I haven't seen these before, and search did not turn anything up on them here, so to broaden the knowledge base, I brought it up.


I was also curious :lol:

I'm IMing with a good friend who is a big racer, he looked and said not worth it. Coils will make a difference. He didn't feel the plugs will make any real difference, I would tend to agree. You can get Autolites for about $1.40 each So under $10 a set. In my opinion, not worth 2.5X the price.

Power in Watts is Voltage multiplied by Current.

How can that plug produce 1 million watts of power if a typical plug only delivers 50W? There's some funny math here. You're still feeding it from the same source, so where's the magic energy coming from? Are they averaging it over a short period of time during the pulse duration only? Probably. I'd rather have a longer duration spark to ignite the flamefront in my cylinders. Seems to me besides price that the only choice is between one long spark at a lower intensity or a bunch of pulses that average out to the same when you factor in the on time and off time of the pulse.


Ok. On their horsepower link, they never state what percent or how many horsepower you will gain. But they do state that you spend $8 per horsepower with their plugs.

They also claim 6% fuel economy increase over standard plugs. do they mean the old plugs you replaced? But wait a minute.....they don't actually CLAIM a specific gain. Look at the information carefully. They state:


6% better fuel economy pays for Pulstar in just 12 months
they say the fuel economy savings CAN put money back in your pocket. Sure it can. But how much do the plugs save? :lol:

They FINALLY get to some numbers on the Test Results page, and I find them very hard to believe. It's the energy of the explosion of the compressed air fuel mixture that produces power. Not the spark that creates the explosion. Sure you need a complete burn, but if I'm getting good combustion now (no fouling), how much more can these do?

Call me a party pooper but at TWENTY FIVE BUCKS EACH you can count me out! :lol:

Spark plugs aren't power adders. I'll move the topic to General Chat for you. ;)

I found it funny that the addition of a coil or transformer can inprove your engine so thoroughly. A coil and a resistor together create a filter so I beleive the product works as described, just I question the benefits. You think that the big3 would have been all over this, incorporating it directly into the ign system, if there were any truth to it. Also then why would Multi Spark systems work so well...

Also the filter would delay spark; enough to cause timing issues? I don't know.

I LOL at their little movie of the combustion propogation. Like the sprak plug would do anything more than ignite the mixture :roll:

I did a HUGE write-up on GM-Trucks.com about Pulstar plugs... Ohm's law, the "science behind them, if the added wattage actually does anything, etc. To make a long story short, there's no performance or economy to be gained. It's another "Tornado Fuel Saver."

willwren 11-23-2007 10:14 AM

That's the key. If the supplied voltage from the coil is the same, how do you increase from 50W to 1 MILLION Watts? :lol:

One billion jigawatts. Get a flux capacitor and start time travelling.

Its watts not voltage.
50w for 30microsconds is .0015watt-seconds
1,000,000w for 2nanoseconds is .002 watt-seconds.

The math almost works; but not quite.

The unknowns are spark voltage, which I assume would get reduced, gap, and resistance of the plug. I don't see how they could keep the stock gap off hand.


Drunken-Sailor do you have a link to that writeup? I wouldn't mid reading it. - Thx.
