You could try a BR6EF plug also. Keep the heat range and move to the non-projected tip.

I think it's got something to do with the voltage though. Definitely concentrate on the voltage drop. Might be worth plopping a stock rebuild alternator in just to see how it acts.

Be expensive, but would be interesting to toss on a dyno with a heavy battery charger maintaining voltage and see if it blows out spark.

funny story, i have an aquaintance as does osie, who has a dynocom dyno in his garage, 10 mins away. @Ltconvert maybe we should call up eric and ask him for a few pulls (and your snowplowing LOL)

we are actually doing just that @Fastbird , reman alt going in, as well as a new exciter pigtail. going to possibly try the spare ground idea too.

I just looked at the log again, the car is breaking up slightly at wot in 3rd gear up to the stripe. only revved to 6350.

dyno log from 2017 shows a voltage drop but only down to 12.4v. at idle back then it was 13.6, now its 13.1, weird.

Work and weather permitting, I'm gonna try to get there also.

Wow. I wouldn't have thought you'd need that small of a gap. Although I had mine (on my Vette) at .028 and it was blowing out, tuner took them down to .024 to get it stable at 17 PSI. Granted that's at over 900 RWHP, moving significantly more air. You could take the gap down some and see how it reacts. You running an OEM or aftermarket coil?

I still like this idea... tighten the gap. But also replace with conventional tips...

LTXtech.com is my drug...

ready to rock for tomorrow, last test and tune of the year at island. praying for some decent traction and a 10.7x

10.78 at 125mph. thats all shes got for the year. the alternator and added ground seems to be helping, i did not see the voltage dropping now. left the 6k tune in it because the track didnt have good traction today.

Just want to thank everyone on here that has helped us along the way. car has totally surprised us and lived up to what people were saying it could do. happy holidays everyone!
