I went to the track the other day and ran a few passes starting with a 10.6 at 136 then 10.4 at 137 then 10.2 at 136. The two last passes are what I really want some input on. How much mph are you supposed to pick up on the back half?

60' 1.53
1/8 6.5
mph 109
1/4 10.02
mph 142

60' 1.53
1/8 6.4
mph 111
1/4 9.96
mph 137

You are really making some power there.
The difference in trap speed may correspond with a quicker ET. I have heard that often at the track. Some of my "quicker" runs were not as "fast" as the slower runs.
It also helps a lot to have some trackside support to analyze the runs after each pass.

automatic....but I changed it from a manual. From the log files it shows I am letting off the gas to about 80% after the 1/8th when it gets kinda squirly uptop.

What rpm are you shifting at?


Plus without making a few 100% throttle passes to go off of, it's hard to get good data.

Yes definitely! I don't even know your setup but the higher shifts points will really help out if you are running a centrifugal blower which is my guess from you traps.
