I am just the messenger of the reports of no improvement who had some questions about your testing procedures. I could question their methods too, but I am not going to put myself in the middle. It is work, but you are the only one making any money. I really don't understand why you expect me to coordinate/quantify/justify the real world testing for you?!? And why you expect your customers to do your real world testing for that matter?

I wouldn't be so skeptical, but these plugs aren't turning into real world mpg results AFAICT. I mean we are talking about folks who can tell if a mirror is removed and NOT noticing any improvement with these plugs.
I think we have people with test skills that are all over the map (I'm not one of the better ones, BTW).

Regarding your mirror delete example, I consider this to be a mod outside the scope of Pulstar testing (apples and oranges). We have discussed on this forum situations in which the ScanGauge is not 100% accurate with all drivetrains under all driving conditions. Without access to the SG source, we have theorized that it extrapolates MPG from other inputs by using a proprietary algorithm.

From my POV, the mirror-delete is an aerodynamic mod. I think the ScanGauge is best suited to measure these mods because aerodynamic mods have a (direct?) "positive effect" on engine load parameters that the ScanGauge measures. When the aero-mods help the engine to do less "work" to go the same speed, the SG can detect this. What I am saying is, the SG is the "right tool for the job" when it comes to measuring the effect of aerodynamic mods.

I think of the Pulstar mod as an "engine combustion mod". I don't think the SG is in a reliable position to test this. I think this needs to be done on a dynamometer, where the number of external parameters are reduced. Most of us don't have this. I am not making a claim for or against Pulstar plugs, but I am saying that our informal "test lab" may not be the "right tool for the job".

I think its great that the CEO of a company would join our little website here to offer his input.

Conversely, I think its a bad idea that the CEO of a company would join this site simply for the purpose of defending his product and not looking at any of the other threads at all. This could change someone's outlook on our ideas, you know?

If I were a betting man, I'd bet on the second option. I believe dparker would be a lot more understanding of our methods if he read more posts, rather than just the one pertaining to his product.

On another note, I think we could really benefit by having CEOs and other representatives of these companies could build products more in line with being "green" and using us as a sounding board. Also, a friendly relationship with someone can never hurt :-)

First tank with the pulstar plugs in netted me a 58.7 mpg tank. Pretty good, but not my best. I will report back after the next tank.


...must resist doing other mods in the mean time!

Now I know I am jumping into this game a little late, but here are my observations on what I have read ...

-Alot of the guys that have or are testing these currently are using older vehicles. Yes we have them working optimally, but still they are older than 4 years in most cases, throwing in all sorts of unknowns.

-Then their are the claims, without going to their site, no one here has discussed any claims regarding unburned fuel. If you have a better spark plug, shouldn't there be less or no unburned fuel and therefore a way to measure and display that data? If they can prove that then the product works and other factors then contribute to the lack of improvement made in claims.

I mean no offense but I am sure all the lab testing done with vehicles didn't include Metro's and 10 year old Civics.

"Best spark plugs to have?"

turbulence ( the spark can actually be "blown out' by these gales) over and over and over again, you'll be satisfied. We're talking many factors, here. Tip erosion, internal resistance, heat range, external corrosion, etc.
Most people have favorite brands. I have many "unfavorite" brands. You never know what you're getting, anymore. The whole world has been "outsourced"! For instance, I used to trust Robert Bosch plugs...until I happened to look closely ... stamped into the main barrel of the plug body one day ( in fine print) ..."Made in India". Oops! Not for me! Sorry.... I still put my trust in US-made Autolites, always have...no problems...ever. I never have liked Champion ( lawn mower plugs) . Other brands? I have no idea of the quality. OEM plugs? Not a good way to judge....Too much cost accounting work, here. Bean counter budgets at work. I don't trust bean counters.

whitevette,

You are right. We call that squish velocity. Spark plugs can tolerate a squish velocity of about 10 meters per second, but Pulstar can take 100 meters per second due to its compressed power.

trikkonceptz,

Also right. We make power by burning the hydrocarbons in the cylinder instead of the catalytic converter. As a result combustion products from a pulse plug are lean. BTW, 35% of vehicles using Pulstar are still under warranty and many of the vehicles we test are older than 10 years...they give us the very best results.

ajax_6531,

I understand your point. It's hard to visit all the different forums out there talking about Pulstar and have the time to detail them all. I would love to understand your methods. If you read my posts you will see that I have detailed ours. Please, someone explain how you go about testing. I think of Pulstar as a green product. Do you know that 1 gallon of gasoline weighs 6.2 lbs. and generates 19.4 pounds of carbon dioxide a prime greenhouse gas? If you have ideas of how we can get our green message across I am all ears.

All,

Thanks for listening. I welcome your insights. We are a new company with an exciting technology, but we don't always know the best way to describe it to people. There has been so much snake oil out there, that any new plug would logically be guilty on arrival. We are only looking for a fair chance to prove ourselves.

Thanks

Hi, D. Parker-
Entertain a thought, please. I mentioned the spark being extinguished in the water vapor tests ... you stated this was called "squish velocity". Is there any possibility you & I could talk further about this "green technology"?
Tell me about "snake oil" ... or the gauntlet imposed by same.
I am at [ chembustion at yahoo dot com ] . Comments? -whitevette
