Made a couple of first ever passes down a dragstrip with my '57 Chevy. I aired down my Nitto drag radials to 22 lbs. With no linelock, I was able to let out some smoke from the Nittos. On the first pass, I came off the line with almost full throttle. Boy, those Nitto's hooked! My shifting was terrible, because my Holley Sniper shift light was flashing like crazy all down the track. I had it set to turn on at 6,300 rpm. I didn't know when to shift because the shift light was flashing almost constantly. I shifted into 2nd, 3rd, 4th, and accidentally popped it into neutral before pulling it back into 4th before running through the traps. ET was a 12.54. The top end MPH clock was obviously messed up.
Here's the thing about my Holley Sniper shift light. It plugs directly into my OBD II port. Problem is, my Dakota Digital gauges are already plugged in there. I purchased an OBD II splitter cable, but I found out that it can't operate two seperate things. So, what I did at the track was unplug my DD gauges, and plug in the shift light. But now I don't have a tach, so I had to trust only the shift light. Honestly, with the way that thing was working, I would have been better off without the shift light.
The second pass wasn't any better. I didn't know what was going on with the shift light, but I kept it plugged in. I short shifted 2nd and 3rd gears, even shifting into 4th to try and stay out of the damned shift light, to no avail. ET on that run was a 12.66 @ 106 mph.
I'm going back to my tuner and have him look at what the line pressures are on my trans, just to make sure they are where they need to be at WOT. And, I have to do something else with the shift light, probably buy another style that wires in.
For whatever reason, my wife didn't get a video of the first pass. Here is a video of the second pass. Sorry she didn't capture my burnout.
