Dark Phoenix

Torque band testing. Measurements taken when car is rolling to eliminate launching from the equation. Since these are speed-time graphs we are interested in the gradient of each line. Steeper slope = more power. As for the data we are interested in the passing speeds within each gea with no shifts in between.

First pic: black line is current setup, while red and green lines were recorded in Aug 05. All runs in 3rd gear. The drop off on the black line just shows that the car was decelerating after the run (i.e. hard braking).

Second pic: black line is current setup in 3rd gear, red line is previous setup in 2nd gear, green line is standard Evo 8 GSR with increased boost in 3rd gear.

Current setup is almost as fast 40-60 mph in 3rd gear as compared to the previous setup in 2nd. Despite getting on the throttle about 0.5 seconds later, the current setup (black line) is also about 1.5 seconds faster to 65 mph compared to the green line.

Preliminary data suggests that the airflow on current setup is choked though... is it time to move on from the stock turbo?

maybe it's time.....to change turbo (not drink tiger beer!). maybe it's time.....for me to install turbo. LOL (i doubt it).

Figures looking promising. =)
