LAME!
Not the plugs, the thread and F-uped test meathod.

 

 

Are you going to answer the question about why so many dyno pulls? Did you only post the lowest & highest runs of the bunch?

 

If you had some one tuning the car at the same time it screws the numbers.
A simple get the car warm do a dyno run change plugs (10 minutes max) let the car warm back up and do another dyno run... = results

 

i think this test is biased...
not to mention you are not testing BRAND NEW NGK plugs vs. brand new pulstar plugs back to back. Same dyno, about same coolant and air temperature with nothing else changed.

 

Here are some numbers that were posted in another forum.
They used a Neon SRT4 for the testing, but at least they did a complete comparison.
They only show an average gain of 3hp over the stock Champions.

But the 350Z comes stock with the Iridiums, which the Pulstar only have a 1hp gain.
For the money, they are not worth it.

 

judging by that chart from a SRT forum, it is not worth the money. I will stick with my $20ish for a set sprakplugs.

 

and Z's can dyno from 220-240+ stock.. pretty wide spread really, depending on temp, humidity, altitude, mileage, dyno type, correction... all sorts of stuff. even on the same dyno on dyno days there can be a decent spread.

you can't claim that low intial numbers completely invalidate gains... but if the gains are a huge jump then you know.

 

I call bs

 

 

^^^


The NGK iridiums were the most consistent in the Srt-4 test and are reasonably priced at $6 each. I see no reason to spend more/stray away from NGK/Denso Iridiums or quality coppers...

 

Whether the plugs actually worked or not, i dont know. All we tried to do is post a dyno graph and we get called liars. If they didnt "tune" it, out of the box those plugs will make your car way lean, so go dyno it with a lean condition like that and see how far you get.

All this criticism is completely un-necessary.

 

^^if u think that these spark plugs cause a lean condition ur a fool--u can't even understand their advertising correctly, let alone conduct a dyno test properly.

The thread title states RESULTS, but the results are bs bc of the tuning in bw testing and are misleading.

The criticism is warranted.

/thread

 

I suppose Nathan @ Enerpulse is lying then..He's only one of the main engineers of the plugs. Thanks, I'll believe him over you anyday.

Additionally, the DG-1 plugs will require a different tuning strategy than a standard set of plugs (more ignition retard because the plugs will make you run leaner).

sure. Move along sheep, but don't mislead the herd.

Your test is bs, the plugs imo are a wash, and u have a hard time facing criticism.

Don't take my word or any other member's opinion, but wholly believe everything someone who is trying to sell u something says?

Y don't u buy a grounding kit, tb spacer, and sprint booster to to along with ur pulse plugs. But don't forget to tune in between runs and post a misleading thread with botched results.

 

I have a couple of questions:

1. How was the AFR measured...WBO2 clipped in the exhaust?

2. How can a spark plug make you go lean?

 

complete failure

 

I would also like to point this out: most products for sale today most likely have an engineer that created it telling us, the consumers, that his product is the next best thing since sliced bread. It's not that they lie or are bad people, it's the bias and lack of objectivity. Need I say more? Draw your own conclusions.

 

Are you going to answer any of the questions being asked? Like, why so many dyno runs in between the 2 you listed?

 

I think the OP is gone.

Word of advice to those that read this thread and wonder what happened here: if you're considering posting results of any test on a public forum like this one, expect the results to be scrutinized by those who read it. It's not personal. That's the nature of the beast. You hang something like this up for everybody to see and make claims, they will be challenged. If your claims are accurate, then you should not have any problems defending them. I don't think that is unreasonable.
