Seen this on TV more MPG & HP

gmctrucks · 06-29-2008, 11:39 PM

More MPG and more HP on the dyno on the same engine about 5 plus more HP and it used less gas to get the dyno results I say in time they will pay off. One always needs more HP and better gas mileage.

Hey guy numbers don't lie my four eye's seen it.

Well that's the kind of performance testing I like. Baselines vs mods on dynos or ET's in 1/4 mile or MPG tests. So many claims are based on the old "Butt Dyno" and those are hard to calibrate.

I do wonder if there is more of matching the right plug to this engine in this phase of its life here than actual plug technology that would have a broad application.

I used to belong to a car club that would host "mod weekends" and "Dyno Days" where we would all help out each other with wrenching etc. On the Dyno days we would test out some of the popular perfomance mods people advertise in magazines and in catalogs like Mid America et al.

I don't know if anyone reads my posts but if you do you might notice that I'm not a fan of the bolt on performance items in general. I don't want to be a wet blanket but I've seen things with big advertising budgets give tiny gains, no gains, and in the case of those air foil things I've actually seen them hurt performance.

You know who else goes to car shows and reads car and truck magazines? The GM engineers read and see all that stuff. They also have engineering degrees and years of experience too. So when someone tells me that GM left an extra 10 MPG on the table by not putting a different style coil on the engine I laugh.

Back to the OP topic and these plugs.

I don't doubt that this plug worked better in this engine than what was in there before. As rings wear OEM spec plugs willl foul faster than a hotter plug will. So I know the OEM spec isn't right for the engine through out its life cycle. With that said, wouldn't it make sense to look at the exhaust gas and see if there is a quantity of unburnt fuel? If the fuel is all burnt when it leaves the engine then that's all we can ask of a plug. Once we find a plug that burns all the fuel there isn't any thing left for a "better" plug to burn. And if we go too far with heat range then we can cause pre-detonation and destroy the engine. Good find on this one. I hope to see it tested in more applications.

Hey I been to Dyno Days here in Houston with my son he has a RX7 I love the way the members/friends help each other out I can say that a lot of the guys might have long hair and so on but they would rather spend there money on there rides which is SUPER to me example like the 240 car club I know some members from there as well and do they ever help each other out like family im an older **** and seeing that makes me feel good when guys/girls get along so good. Guys/Girls do your racing at the track why ruin your life if you kill someone.

Very well said z07;

I have run many plugs on engines that we had on the Dyno, and on my latest LS"7" ran these exact plugs.
I will not be running these plugs in this engine. I had to try to see where all of the hype was, and I have come to the conclusion that most engines that realized any gains, were engines that would have benifited from a new set of plugs anyway.
I am not a fan of rare earth, or precious metal products, and have to lean on ny knowledge of plain old electricity. Copper seems to have always been the best conductor, with the highest performance. Even the platinum plugs, and iridium plugs did not perform as well, and were more likely to foul and fail when exposed to additional oil in the cylinder, where the copper plug still ran fine.
Real performance gains were achieved by "indexing" a standard plug, and exposing the "kernal" to the center of the combustion chamber, and away from the sides of the cylinder.
Shrouding the spark kernal and limiting the exposure of the electrode will require a better spark to achieve the same amount of combustion. This can only be achieved by a greater amount of voltage, and not necessarily a different heat range.
Heat ranges are a value measured by how well a plug transfers heat from the combustion chamber to the head. Most believe that it is the intensity of the spark, and this is a falacy, and a myth.
It is true that a hotter plug can cause detonation, because the plug hold more heat in the tip, and does not transfer heat to the cylinder head.

At any rate, I am not a buyer of these style plugs. There have been many similar designs on the market, and none have impressed me to the point where I would be interested in spending such a large amount of money.

Give me plenty of voltage, and a "plain Jane" copper plug any day.
