yep. just when I thought it wouldn't get better, I pulled a 12.71 out of my... somewhere.
I still have cbrrmike's SLP lid, same flowmaster muffler, and I decided to put some 100 octane gas in it, because I was about to run out of gas
60' - 1.841
330 - 5.367
1/8 - 8.210
1/8 mph - 88.62
1000' - 10.644
1/4 -
12.712
1/4 mph - 109.76
I had one more slip that was a 1.83x 60 and 5.32x 330, which would have put me at a 12.67 or so, but I missed 3rd. oops.
