okay so i'm trying to do a little analysis of my times... figure out why i'm so slow now. i think its because of the gearing... mainly 4th (which i was a little worried would be too tall...).
old gears (1-4):
4.105 fd
3.31
1.833
1.31
1.03
new gears:
3.85 fd
3.31
1.833
1.23
.914
here's some timeslips
best old slip:
60- 1.971
330- 5.451
1/8- 8.226
mph- 87.31
1000-10.604
1/4- 12.611
mph- 111.27
2nd best old slip:
60- 2.04
330- 5.654
1/8- 8.475
mph- 87.18
1000-10.892
1/4- 12.926
mph- 109.93
best new slip (i made 13 runs on saturday):
60- 2.153
330- 5.845
1/8- 8.76
mph- 85.95
1000-11.22
1/4- 13.309
mph- 110.15
i know my 60's sucked but with a 2.36 60' last year i ran a 13.25, and with a 2.10 i ran a 13.15. last year it took a horrendous 2.60 to bump me back to a 13.7.... but this weekend i did a 13.64 with a 2.27 60 foot.
argghhhh. the tune is the same, tires are the same, tire pressure is the same (15 psi). the only difference is in the tranny... the quaife and taller gears.
i dropped my pressure later in the day (a few runs after my 13.309 run) to 12psi hoping to hook up better... it didnt help, it just dropped my trap speed to 107 (consistantly).
i also made some 1/8th runs last year, crossing the finish on the revlimiter in 3rd. i trapped consistantly 87mph... so with the old gearing i was shifting out of 3rd at mid track. with the new gears i dont leave 3rd till almost 95...
any ideas or suggestions would be appreciated... but i think i'm going to need to tear it apart again
