As I have mentioned, in my build thread and other places, this is my first build at this level. Yesterday was a HUGE learning curve. My first pass was a 12.21 with a 1.97 60' holy crap.... a D-9 Cat has a better 60'. With my 4.11 gears and 33x21.5 QTP tires it loads the car down way to much. It takes for ever to get up on the tires. 1st: RT- 1.245 (took my sweet time) 60' - 1.971 330 - 5.272 1/8 - 7.947 @ 92.11 1000 - 10.246 1/4 - 12.213 @ 112.28 2nd: RT - .466 60' - 2.008 330 - 5.326 1/8 - 7.987 @ 92.66 1000 - 10.264 1/4 - 12.194 @ 116.07 3rd: RT - .432 60' - 1.836 330 - 5.052 1/8 - 7.671 @ 94.01 1000 - 9.914 1/4 - 11.814 @ 117.93 For the 3rd pass we turned the bottle on (225 kit), well the micro switch was not set properly and the linkage arm went right on by. So the kit only blipped for a nanosecond. Went back the pit a fixed the micro switch problem. And on the 4th pass.....I broke the rear dif. probably sheered the pinion. Car transfered the fell on her face. no go no mo! pulled to the side got pushed back. No leaks that was good. Upon further inspection at the pit found the drive shaft does not turn when the car is pushed. Gonna preform the autopsy this weekend to see for sure what went south. As MrDragster and others have mentioned. With my set up I will be leaving some 60' on the table. Hell I left it on the table, on the counter, on the floor, I got buckets of it! Here is a video of the 3rd pass. Note that I don't go into high gear till about the 1000' Maybe I should have went to Bonneville. BTW the car weighs 3710 with both bottles and both tanks full and my big carcass.
