Sounds about right, but why the low mph? I was hoping to be in the
low 12's, but with a 2.194 sec. 60' time, 12.868 @ 115.13 mph was the
best I could come up with. That was with 10psi and a 75 shot on a
stock automatic (motor).

My guess is it's in the tires. Didn't you run stock size
street tires (like RE-71s)? With his 60ft times, you'd
probably have around the same ET. I think Ric used Nitto drag
radials, probably not a stock size. I imagine the rolling
resistance cuts down on the trap speed some. - Beau

Also the faster you get out of the hole, the less (distance) you have to
build mph (relatively). In other words the same car running a 1.9 vs 2.1
60 ft will probably have slightly less mph at the trap speed. Try coming
out of the hole really slow. Your trap speed will be high.
