Plug Pictures - 125-shot These plugs saw one quarter-mile, 125-shot pass and a return to the staging area. Timing was 19.5 degrees. Wideband averaged 12.4:1 I have experimented with less timing (18.0) and more fuel (11.4:1) but the car always traps around 128, 129 mph with a 125-shot. Do I need to add fuel? I want to know if I’m ready to step up to a 150-shot. Thanks.

I agree tho. I'm sure its safe as is, just try and hammer that fact home.
looks pretty good to me. Id be happy with them, then play with fuel or timing one at a time and see what the mph does. As long as the wind isnt gusting there at Infineon. haha

The immediate shutdown recommendation is obviously best but it doesn't follow that plugs with minimal drive time can tell you nothing. Nitrous novices don't necessarily need the same information as someone tuning a 300-shot. Evidence of too much timing, too much fuel, or detonation will not be erased by an easy drive back to the pits.

They are covered up to some degree. Also the load placed on the motor from being left in gear can effect the timing mark very easily. I may have seemed that I was being over zealous but that is just from being on keyboard. Again I just prefer to have absolutely no drive time on them. But that is IMO. By no means fact. The other guys chiming in here are at LEAST as knowledgeable so you have plenty of good direction. Both them as well run very fast for there given combination.

I think the fact there novices is all the more reason to get the most accurate and clear picture. Why would you not do an immediate shutdown when you know it would give you a better read? You seem to have some tuning knowledge and are trying to be cautious by slowly moving up in jets, might as well get the most accurate read you can.

And we were all a novice and some point. I especially have learned a lot from Dave in the last year. There is always more to learn.
As I said. Lots of smart guys in here. You are headed in the right direction.
