hah.. cant get much slower than me.. LOL
i have a couple more dyno runs on DV, but havent had time to upload them also..
i'm like infamous all over the world and stuff... kickass!
i do kinda wonder who all has seen it.
DB- you should have seen the girl.. her *censored* got hard. HEHEHE

RT KILLA: I'm going to the track saturday. they do feel more responsive! i'll let ya know how they do. does anybody know where i can get those radiation warning signs? I want to give a fair warning to my fellow racers about the radiation that comes off these uridum plugs! Never let it be said that JL never WARNED Them!

IRIDIUM BLOWS CHUNKS FOR CONDUCTIVITY! (and a fine wire electrode sux *** too!)

Iridium is a HORRIBLE conductor of electricity. It's nearly as bad as Platinum (keep reading down below for my link to my other post that shows each elements conductivity charts used in hipo sparkplugs). Also the fine wire eletrode is NOT what we want to be using in a high performance situation like ours.
When reading spark plug advertisements, one can get the impression that small diameter center electrodes, uniquely shaped electrodes or built-in resistors are the best. Think again. A RESISTOR is exactly what the word implies. When the spark crosses the point of resistance much of the spark energy is lost. A resistor is like an electronic obstacle and could be the cause for a weak spark. Due to manufacturing tolerances and lack of quality control, even non-resistor spark plugs often have a resistance of 10, 100 or even 1000 Ohms. Always check spark plugs for resistance before use.
Using spark plugs that have resistance due to manufacturing tolerances, internal damage or by design will weaken the spark, which could result in lost horsepower and poor fuel efficiency.
What about electrode shape? Spark plug manufacturers will tell you that a small diameter center electrode makes it easier for the spark to jump the electrode gap. This is true, but what they are not saying is that such a spark is also weaker, since it takes a lower voltage to jump the gap. A spark jumps the electrode gap when the voltage at the electrodes reaches the ionization point, since the ionization point, (voltage needed to jump the gap), is lower when a small diameter center electrode is utilized, spark voltage is also lower. Exactly what a performance orientated consumer doesn't want.

Question:
Isn't a split electrode or a fine wire electrode better?
Answer:
It depends on the application. Since the ionization voltage of spark plugs with split electrodes or fine wire electrodes is lower, they are perfect for older vehicles with weak ignition systems. But since spark voltage is lower, they are not desired for performance applications. In addition, electrical energy travels on the outside of a conductor and not through the middle as commonly assumed, and since a large diameter center electrode offers a larger surface area, spark carrying ability is increased when the center electrode has a large diameter. To put it simply, you can't fit a big spark through a tiny electrode.

Question:
Isn't copper a good conductor?
Answer:
Yes, but not the best. Silver is the best. Also, the electrodes of spark plugs with so called "copper electrodes" are not solid copper, they are copper core. This means, an electrode made out of a poor conducting material, usually nickel-alloy, with a copper core. This only benefits heat dissipation, not performance.

I suggest all those who haven't read my thread on the Beru Silverstones sold by Nology to read it now:
https://www.f150online.com/forums/sh...1&pagenumber=2
In it you will see the breakdowns of the 4 main used metals in hipo sparkplugs and will see how they stack up against each other.
Anyway, JL, not trying to start stuff w/ ya man. I know you got the hookup and I know you're truck is going to run well, and I hope it makes some new times!
Later,
BfB

BFB: You shouldn't even ? O JL Abilities! J/K seriously i'll keep in mind what you said. it makes perfect sence! however i perfer to do my testing and Final Judgement call in the real world conditions! Thats on the old 1320! maybe i can test a set of those other plugs your refering too at a later time. thanx again for your input you made it very interesting! however i plan to go with the testing of the uridium plugs tommorow @ the track. i hope all goes well. i'm trying my gear on right now. here's a pitcure of me with it on what do you think? hope i don't get my fellow racers to concernd over these plugs from space! JL

Hey Johnny Lightning, DId you Gap the Iridiuim plugs to factory specs or did you leave them at the pre-gapped setting of .044. I have my set coming today and want to have them gapped correctly. Denso website says do not gap the plugs at all unless you have a power adder such as supercharger,turbocharger, etc. please let me know what you set them at. thanks 95rcobra.

Or, JL, if you have another laying around do you mind (hey, maybe pull one to see? hehehe, like a front one LoL).
I'll compare them to the Silverstone's when mine come in and post back. I'll try and get a comparison of all the plugs we all use pretty soon.

NEVERMIND, LoL! I found the real site.
Here (thanks Speedin' Bob):
www.iridiumpower.com
http://www.iridiumpower.com/findmypart.asp
It also doesn't state to gap on the '00 chart as earlier stated, but on the '99 chart it states .044. I assume this is the stock gap of these plugs from the factory. JL, you measured .038 stock not touched, or you gapped them down to that?
Now, if you use their cross-reference chart for other plug manufacturers (found here: http://www.iridiumpower.com/crossreference.asp ) you'll see that for Autolite this is what they recommend:
[code]103 IT20
104 IT16
104 IT20
105 IT16
106 IT16
[/code]
Champion's website (located here: http://webepc.com/cgi-bin/sewse?/hom...0.cmm%2Bfedmog ) states for '00 Lightnings we need RS12YC (they do not have a listing for '99 or '01, although they are the same).
For Denso Iridium's they recommend cross-referencing the Champion's to Iridium's as such:
[code]RS12YC IT16[/code]
Those who want a lil colder plug go w/ the IT20's, and those who want a "stock" plug go w/ the IT16's.

Factory Gap setting for the 99-00 lightnings is .054 the it16 denso iridiums are set at .044 and JL says .038 Do they all work! I have been on this Denso iridium website for the last week and they have changed it since the other day. when I went in there to find the application for my 2000 L it said the gap was .054 for the it-16 plug. now there is just a black box there. I spoke to a tech guy at Denso today named Aaron and he really had no clue about these plugs or how they should be gapped or if they should be left alone and not gapped. it really scared the hell out of me that this was their tech guy and it sounded like he did not know too much. go figure. later 95rcobra.

Hey, JL, when you get a chance let us know if you gapped yours down to .038 or is that what they measured out of the box? I have a feeling you down gapped them.
