Thats pretty cool for sure. Problem is too many will believe their car would be that much faster by simply swapping in an 8 speed. Some combos will benefit , and some wont make much a difference at all. To many variables. I know of a guy who swapped out a 46re to an 8 speed and gained a little over a.15 in the 1/4 in his hemi powered Dakota. Its an awesome trans though for sure.
Over the NAG1 it was said the biggest gains were from 2nd to 5th with the ZF, and thats over a 5-speed. Could be pretty big over 3 spd, or a glide.
