Here is the latest shot of my car at the track on 03/05/2017. I made two time runs before i opened the fuel station on Sunday. Last month Jan. 8 i made two runs before selling fuel.The weather was 43-53 deg. hum was 10-15% what they call mine shaft air.Run #1 60 ft 1.642 ,1/8 7.391 @94.86, 1/4 mile 11.541 @116.93. Run #2 60 ft. 1.637, 1/8 7.399 @ 98.01, 1/4 mile 11.561 @ 118.45.
All runs were made leaving off foot brake and shift @ 7,000 rpm each gear change. Theses runs are my best to date.
After those runs I installed a trans-brake in my 4l80E transmission. this trans-
brake works with my transmission controller. I can leave off the button and
trans will shift @ WOT 7,000 rpm each gear.
I tried a different launch on 03-05-2017. Left line at 2800 rpm and adjusted
controller to shift at 6400 rpm on each gear change. (dyno shows max HP and TQ at that rpm).
The weather was 71 deg. and hum was 50% Run #1 60 ft. 1.650, 1/8 7.447
@ 91.65 , 1/4 mile was 11.647 @ 118.87 mph. Run #2 60 ft. 1.642 , 1/8
7.422 @ 91.88 1/4 11.629 @ 112.85. second run i lifted early.
This was the first time out with trans-brake. I'll make some changes to shift
controller.Go back to 7000 rpm WOT shift.
photo is a copy that i have ordered from the track.
