1/4 mile rear end gearing I posted a thread in the forced induction section that may actually belong here. What gearing should I go with in order to finish the 1/4 mile without shifting out of 4th?
I just wanted some opinions/examples from those with forced induction who drag race. Check out the thread --

Assuming 3.89 gear and tire diameter of 25.7
Refer to your redline and you will need to determine if you feel your car will be faster than the 4th gear MPH at the end of the 1/4 mile.
RPM 1 2 3 4 5 6
6000 44 66 91 118 159 236
6100 45 67 92 120 162 240
6200 46 68 94 122 165 244
6300 47 70 95 124 167 248
6400 47 71 97 126 170 252
6500 48 72 98 128 173 256
6600 49 73 100 130 175 259
6700 50 74 101 132 178 263
6800 50 75 103 134 181 267
6900 51 76 104 136 183 271
7000 52 77 106 138 186 275
