Car is running great, strong, etc...I have ATAP1 and EFI LIve Pro, however only autotap is working now, cable issue with efi live...

ran 175 shot and data logged, couldnt see KR on basic autotap so I dont know about this, but 02 were 400-900 and dipped to 200 for a split second...

everything felt fine. pulled a plug today to check it, and it looks like rust all over the plug (tip, ceramic, everything).

Don't know exactly what this type of coloration means, but obviously something not right.

On a 150 shot and 3 degrees out, plugs looked fine (pump gas)...

Now on 175 shot and 2 degrees out with Torco accelerator (about 105 ocatane unleaded total), the plugs are discolored...

Car: 2000 Camaro, 382 stroker, 11:1 CR, X1 cam, stg 2 heads, auto, NX GM MAF kit jetted for 175, TOrco additive with Sunoco 94 octane, TR6 gapped at .038.

I am planning on going with TR-8's gapped at .030-.035 and using a 200 shot with 4-6 degrees timing out. BUT obviousl need to figure this one out. If possible, I will have Greg Banish take a look at it on the dyno since he tuned the car NA.

Any ideas about the rust colored brown coloring, looks like it is actually a "deposit" and not just color...like actual rust was poweder coated on it! Before, with the 150 shot, the plugs looked very clean, almost like it was too hot of a plug though (kind of white-ish)...

Thanks,

It's possible you glazed your plugs. That's usually caused by the setup going lean for just a little bit and actually forming a hard coating around itself. I'm not sure on the Torco, but normally different additives and octanes change colors. Higher octane leaded fuel tends to turn my plugs a gray tint, while a slightly rich pump gas goes a little brown. Did you look at your plugs with a plug microscope or was it just the naked eye. The real story is down in the area you can't see without a lighted scope.

just naked eye through magnifying glass...where can I get a microscope?

Heres a link to one. You just have to look around at race shops and such. Although a decent magnifying glass and a lot of light work pretty well for a good bit cheaper.

I have seen this when on a car when you run certain kinds of Octane booster's through the engine. The one I remember was the NOS brand, It made the plugs look like you are describing.

Same thing with NOS race booster additive. I didn't like that and the car didn't seem to like it. So I never used it again TR6 gapped .040. 150 dry.

wait till you see the inside of your combustion chamber, it will be all the same color.
i don't think its anything more than dicoloration caused by the additive. i had the heads off several times without any discoloration till i used torco then i got the same results you did.
