Bad day at the track

Not a good day at the track
Well I was looking for that 10.80 pass today but that wasnt going to happen . Car ran like crap today missing and popping. I think my charging system is breaking down under load I will check that tonight or tomorrow. Best pass of the day was:

1.64 60 foot
7.42 1/8 mile @106
11.13 at 126 1/4

1.92 60 foot
7.68 1/8 mile at 102
11.33 @ 122

and the rest of the passes were 12.20's around 80 mph. Both of those runs were popping.
The car didnt have any knock and I noticed that charging voltage was around low 12 volts during popping.

Anybody ever have popping and missing during there runs??
This car is starting to become very annoying

Charging system crappin out??

NMB, from the MPH you are posting for the 1/8 and the 1/4, it looks like there's something else going on besides the volts..
106 in the 1/8th should be well into the 6's and at 126 in the 1/4, my data shows the car should be in the 10.50 range. If the car goes the MPH, then the HP is evidently there at the end of the track!! Is this a sanctioned track??

Here's what I have from literally 1000's of logged runs at NHRA events...all the way from 12.00 sec to 4.50.
we'll work backwards.
1/4-126mph, 10.50et, 1/8- 6.65, 330'- 4.26, 60'- 1.43.

It appears you have some serious traction problems.. either yours or the track is not prepped, OR both.
I wouldn't get PO'd at the car.. [not yet anyhow!!]
Do the testing and repair the charging, then go tow ork getting the car to give up some 1.50 short times and it's "no sweat" 10's!!
What do you have for scan data?? Could be there's another cause for the popping. [Lo volts to the pump, is a prime concern now]
What do the plugs look like??
Dropping to 12's looks as tho whatever is wrong is getting worse REAL fast!!
