Shift Point discussion, 7K or higher for MR's
I went to the dragstrip last night with my Evo and logged all of my runs. One of the things I wanted to try to discover was what effect using different shift points had on my car. I was able to create an interesting visual from the log.
These HP / TQ figures are derived from airflow/rpm instead of time/distance/work calculations.
2byte rpm values
1st 7558
2nd 7878
3rd 7886
4th 7843
Conventional Evo wisdom, stock turbo doesnt make usable torque above 7K. Airflow may say otherwise. Discuss.

The next time I go to the track I'll make sure to get it both ways and I'll update the thread and PM you. Note not all cars have a powerband like mine so this may not change conventional wisdom. I wasnt looking for an argument with Warrtalon in your thread, I'm looking for my ideal shift points too.

I'm not going to simply say 7K and that's it. I'm more practical by weighing all of the necessary and required numbers to make the best decision. If you have a dyno chart of your tune available, this website should give you a hand.
