Its hard to see in the pic, but I didn't notice a complete ring of carbon around the base. Car has run about 10 dyno runs, 30 drag strip passes and still oil level is full, so anything on the plug is burned fuel. They were put in new today.

Also, thats 2 N/A, 3 nitrous passes and 40 mins of driving on the plug.
I know you are supposed to pull them right away but if you can detect anything from this plug anyway, post up.

You cannot get any good reading on plugs that have multiple passes or dyno runs on them. 1 pull, and chk

I think he knows that but he is just posting this pic to see if any more knowledgeable guys can just see anything out of the ordinary on this plug.

The car has gone through so many cycles, the plug data is useless.

If it were a nitrous pass done correctly I would say WAYYYY rich and timing looked good.lol...

In all seriousness, if you could post up some accurate nitrous plugs we will be glad to help you with the tune-up.

What method did you use to cut your plugs?

Like Carter said... Also, what size fuel jet in the plate? Fuel jet settings from several companies are already on the rich side and timing retard affects n/f ratio also..

Dremel and a vice.

Ha, I knew you would say that but thanks for the timing info. I'll get it next time at track, hopefully next weekend.
