He posted a response to my victory on the mnet thread. I kinda feel bad for him that he can't get his to work.

dont feel bad.

I still think it's in his wiring.

internal wiring....in his brain.

y8s 12-17-2007 09:39 AM

is there some reason he can't get a local person to help him?

jrmotorsports55 12-17-2007 01:58 PM

Probably is in the wiring. Mine is a 99, and I used a trailer wiring harness to wire it up. Very easy. No problems other than the dead battery (self inflicted).

Y8s,
Have you noticed anything positive by running the COPs on your '01? I haven't done it yet as I don't have a real reason to push the envelop in the winter on my crappy tires and I'm not misfiring. I'm debating on whether or not it'll be worth the trouble, especially just running the 2560 at 11 psi.

hard to say. does it feel slightly smoother? yah.

can I run .040 spark gap on my iridiums? yah.

does it look neat? yah.

that's all I can say for now.

y8s. Did you notice any better fuel economy?

eek :eek: on the iridiums :td: never never never run platinum plugs on no2 or boosted engines.

Braineack 12-18-2007 12:35 PM

Because Iridium and Platinum are the same thing. And it's not like Iridium is 8 times stronger than platinum, 6 times harder, and with a melting point 1200°F higher.

lazzer408 12-18-2007 12:45 PM

It may just be bad for nos use. Maybe ok for turbo.

From NGK's website.

Q: "Can I use platinum plugs with nitrous injection? "

A: "No, it is not suggested to use platinum plugs with nitrous oxide injection.
There have been instances where the platinum tip has lost its bond to either the center or ground electrode when they were used in a motor with nitrous.
Thus far the tech's say they have had no problems using Iridium plugs with nitrous."

It's great platinum handles the heat...if it's on the plug.

sometimes I can't help but wonder if your gerbil is ever spinning it's wheel.

I wonder if you actually know why platinums aren't suggested, without goggling.

TurboTim 12-18-2007 01:12 PM

I can't remember the last time I changed a plug. Whatever. My shit still starts up and makes power. I'm happy. hahahahaaaaaaaa

I think i use NGK-R's.

Braineack 12-18-2007 01:38 PM

or someone please just comment on lazzer's reading comprehension.

haven't driven it enough to notice fuel economy. plus right after i switched, the badgas season started.

and as to the platinum/iridium thing, well, here:

If NGK is warning me against tip failure that's good enough for me. If not, the lower price of copper plugs is good enough for me. If not, the fact that my copper plugs run great is good enough for me. C is for cookie and, well... an element table won't tell me the quality of a product unless it's someone selling me fireplace logs made out of Mg.

I'm wondering of the COP helped because it cured a missfire I didn't know I had or if other people have noticed better mpg as well.

let me clarify the ponit.

NGK says never run platinums.

I don't run platinums.

nuf said.

PLATINUM AND IRIDIUM ARE TWO DIFFERENT ELEMENTS FUCKTARD
.

the reason copper is the most used plug is because of it's bomb ass high thermal conductiveness.

While platinum has a higher tip melting point, it's thermal conductive rating is much lower than copper. which means the tip stays hot after the spark has ignited, as the new a/f mixture enter the chamber the hot tip can prematurely ignite the mix or pre-ignition.

iridium not only has a melting point nearly x2 the amount of copper, it's thermal conductive point is much higher than platinums. therefore the worry of pre-ignition is reduced greatly.

but you are right, copper is the best compromise, with a low melting point comparatively, it has the highest thermal conductive rate of any metal on earth, therefore it sheds the heat fast and pre-ignition worries are the lowest, however they may need to be replace most often as the tip wears down....however at $1 a pop, it's not a big deal.

please lazzer, for the love of god, read that and comprehend it and then respond that you understand the difference between platinum and iridium and understand why one is different/better than the other.
