Looks like a weld joint in the close-up photo. Their web site has information on the "guts". They must have some level of confidence in the results, why else would they subject themselves to the scrutiny they will get here?

 

I am really interested in the results!!! I bought 4 Pulstar plugs for my wifes ZX2. I wanted to test the gas mileage in her car before I invested $200+ into the Z06. We shall see!!!

 

Looking forward to the test!

 

This should be interesting......... ttt

 

I would put $20 on a bet that there isn't nothing but normal spark plug guts inside if I were to cut one of them things in half, right down the middle lengthwise. Then I would post pictures of that on every forum known to man.

 

The problem with using gas mileage as a measure is that if you want to get more miles out of a full tank of gas, you will adjust your driving to accomplish just that.

 

Been reading this interesting discussion. This item reminds me of some of the other miracles of the past. Anybody remember the funny shaped black rocket shaped spark enhancer from around the early sixties, you plugged it into the center of the coil and then the high voltage wire from it to the distributor, or it might have been plugged into the distributor and then the wire from it to the coil,( long time ago). In the live displays all of a sudden the engine would speed up and seem to run better, further scrutiny uncovered the true scam that it was. And how about the tornado that goes in the air box, real lab testing showed that to be actually worse for gas mileage and horsepower. Then there were the so called better sparkplugs with 2, 4, and 6 electrodes, they didn't prove to be of any benefit either, (except in true racing engines for indexing purposes,and those gains are miniscule at best). It seems the only true advance in sparkplugs is the platinum, and that only enhances longevity, not mileage or horsepower. It is the overall ignition system that can make a difference, such as having a coil on every plug. Or if you were running a super super high compression like 13 .1 or more you might need a better plug to stand up to the compression, for a higher voltage spark and for reliabilitys sake.
If you read the testing procedure , it states that after testing the stock car, they then reconditioned it with fuel and tires. And supposedly that is how they got their results. Now if you take a stock car and add racing fuel and play with the tune a bit I suspect you can produce more horsepower and torque with any sparkplug, and if you change tires to skinnier ones and fill them to 45 lbs of air you will probably get better fuel economy with any sparkplug. And it also states that they created the testing procedure, and I suspect the test lab also.
So at the end of the day I will be super surprised if legitimate testing of exactly like cars produces any significantly better numbers for this product. But I have an open mind and am always looking for true improvements in technology.
The above is just my opinion. And I'm sure there are a lot smarter than me out there.
Good Luck Guys.

 

As I posted before I bought a set for my wifes car. Its a 4 cylinder car so I'm not expecting to much from my own tests. Her car needed a tune up anyway and I just read about these "new" spark plugs so I figured what the heck. If I do see results (in my testing) then I may invest in the pulstar plugs for the vette. This test will definately help.

These plugs may very well be nothing but overpriced "regular" spark plugs, but at least RevXtreme is testing them, and Pulstar is behind it. If someone wants to cut one in half to see whats inside that would be cool.

Happily waiting for the results!!!

 

when is the big test? or did this happen already and got to snake oil result?

 

It is important not to rush this and do it right. Believe it or not, as an educator I am trying to adhere to the scientific method as much as possible. So I have to enusre that all the variables are covered and the test conditions are correct and that the vehicles involved are also tuned correctly.

What ever the results turn out to be, I want to be able to say for certain that they are truly accurate. To do that, it will take a little while longer to get everything lined up, but to me I think in this case it is wise to be thorough and not rush things to achieve accurate results.

I appreciate your continued patience.

 

Who remembers Split-Fire plugs? Lotsa hype and PR around them, plus a big price. Final results showed no performance improvement. Seems like every few years someone comes up with a great "new idea" for plugs. As previously stated, the platinum tip for extended life was one real major improvement. But going back many years and from personal experience, the Champion extended tip plug design was the hot set up for the '57 Corvette 270 HP engines vs. the AC standard flush tip.

 

O.K. - what's the deal? It's been long enough. My detector is starting to chirp.

 

False alarm my friend.

A few logistical issues have arisen in getting the proper test vehicles secured and setting up the parameters. We were originally going to use my own modified H/C 98 vert, but I felt that we needed to use a neutral party modified vette, just to be on the up and up. Don't want to appear biased.

There is really no rush here, what ever the test results are, we will post them. We will have video and pictures of the entire process. Our integrity is what's important, and everyone deserves to have a test that is well done and leaves no doubt either way as to the end results.

If there are no gains, we will post them. If there are gains, we post those too and have undeniable proof whichever way the test goes.

Both I and Tracy apologize for the delay, but in the end it will be worth it.

Thank you

 

What a joke this is, anyone who even understands even a little bit about engines knows no sparkplug in our vettes with engine management, electronic spark control, 8 coils and very short plug wires can there be any gain to overcome $200 a set

Why is this being dragged on when the worst case tests were aready done weeks ago by a local C6 owner right at the vendor's own shop and dyno and several hours of testing showed less then 3 HP gain

Sheesh just imagine the cost of changing these every 30,000 miles and no one has even asked since these plugs show no approval what this would do to GM warranty and speaking of GM why if such gains were possible why GM and no other car maker uses them as standard sparkplug ?

Just do the seach in the C6 section for the results were posted there which shows the orginal poster of gaining 40 HP at flywheel as bogus.

In looking at the plug's design at the least as they age they will put out noise that will be picked up in car electronics and cause weird faults.
