Lesson learned
Post up the jets you are using in each.
also stages need less timing for the same shot.
AR94 is a projected tip plug correct?
If you know enough to not take these guys advice then you would know to not use that plug.
If #7 is black then it is probably hurt (pinch ring and oil gets by)
Some lessons are learned the hard way on N20.... I've had my share.

I never claimed to know it all. If I came across that way I appoligize. Troubleshooting over the internet doesn't work very well.
It has 131,000 miles. It's had a hard life and a lot of nitrous through it. I know it only takes one hiccup to end the engines life. Let's look @ the mph instead of 1/4 mile. 128 is what is has trapped. That 10.6 run was on a spinning 1.52 60', but is still my PB.

The plug was just plain and simple too hot of a heat range for that kind of cylinder pressure. You may have gotten lucky and it just passed out the exhaust without any damage. With the kind of cylinder pressure that you probably don't understand comes from stacking 2 kits on top of each other...you have to have your A game on. An AR94 is not your A game. Its a projected tip for one and way too hoot of a heat range to be considered for anything more then an NA plug. A non projected tip 2 steps colder then what that AR94 equates to will help that motor along and most likely pick up some more power on the bottle. 15* timing is probably not the cause of the catastrophe but there is a such thing as too little timing also not helping but hurting. 128 mph is not impressive for 200 pills on top of a motor that makes 380 at the wheels already. That's just coming from someone more experienced then yourself and a few others in this thread who have a grasp of what it should be running. Well over 130 is where you should be given the plugs are right heat range and the gap is tight around .026 to .028. Cutting the ground strap back on NGKs has produced some ET for me. I just rather buy the Autolite plugs since its already done for me. lol
So, you guys think he would've gotten away with using NGK TR7 (BR7EF) non-projected plugs, even though they're the same heat range as the AR94s? I just installed a set of TR7s gapped at .032 for upping my shot (NX wet 175-200). I don't wanna make a mistake of NOT going with colder plugs.
Weird, Nathan and I were just chatting the other day about plugs.

I'll give the autolites a try. I hope that you are right. Maybe I can throw some timing back in it. If you are right, you'll have some drinks on me coming your way.

so question is for a 200-250 shot car would you run a non projected resistor plug like the NGK BR7EF or a projected non resistor plug like the NGK R5724-8
yes ones a 7 and ones a 8 but im really looking for advantages disadvantages between the projected vs non projected, resistor vs non resistor?

Stay away from projected tip plugs and N20.
I'd say 150 or more start looking into non-projected plugs... heat range will depend on how much nitrous and how much power it makes N/A.
A cold plug wont hurt power much at all (maybe 5hp if its 1 step to cold) but a hot one will burn some **** up.
I run 7's on the motor and 11's with both guns on.

200 I would start with a 8-9 (get the tune up right)
Then 250 goto the next step colder.

Bank 1 has the two cylinders that are known for going lean 7 and 5. If you went lean on the dry shot in one of these cylinders it could kill the plug. Since you are running MAf and O2's that one dead plug would cause the computer to lean out that bank. Being one plug down the O2 reads rich and cuts fuel. This would then cause the other plugs to start melting ground staps. I had this happen in my Z06 except on the passenger side.

Dont let the stock O2's correct. best bet is tune the car and turn them off.
