It shows speed instead of rpm due to the fact we were mapping shift points on the other runs. I do have sheets with all the info in data form instead of graphs.
The A/F was almost constant, only changing from a low of 11.1 to a high of 11.4.
The torque curve is like all 4 . 9s in that it starts high and goes down from there. The hp curve is flat from the start of the run till near the end.
The first 3rd gear pull, it had 160.7hp @4800 and 216trq @3800
For the last pull I moved the timing from a base setting of 12 to 16 degrees with the timing control bypassed.
This gave me the days best of 169.6hp@4800 and 218trq @3800.
All the runs ended at 4800rpm in high gear which is 102mph. The factory speed limiter is 118mph. With the change from 2.73 to 3.06 final drive and 24" tires, the computer thinks I am going 118 at an actual 102.
I wish it could have pulled higher because in both cases it made a big hp jump from 4400 to 4800.
It was 7hp in the first pull and 10hp in the last with the advanced timing.
I am now going to send all the data I have to Rocksrawl and get a new chip. I will dyno it when I get it back to see the changes.
