Here is some math for you from that old thread.
It shows rear end gears and the MPH at redline.
I mean, theoretically, you could do 4:30s, and it would closely match the MT82/3:73s for gears 1-3.

If you look closely, the reality is that you will see the Tremec XL (2.97 type) with 4:10s is really closest to an MT82 with 3:55s.
That's why I say I am more streetable and shift less than I used to.

MT82 3:55s
43 65 94 120 158 243

MT82 3:73s
41 62 89 114 151 232

Tremec close ratio (2.97...) 4:10s
46 65 94 137 171 217

Tremec (2.97...) 4:30s
44 62 89 131 163 207
