what should you expect . If you go from a m6 3.42 10bolt rear to a 9in 4.11 gear ratio truetrac rear what should you see in the 1/8 or 1/4 diffrence from one to another on motor .1-.3 if you launch at about 4000- 5500 ? I know with spray is should help more than on motor .
That is a very hard question to answer. Traction plays such an important part, as well as how the car reacts, plus engine build in relation to the cam, etc.
I'd say you would see an average of two to three tenths knocked off your 1/4 mile time. Bob

Ya i should have stated on drag radials or et streets . You should also see almsot all your et dropping by the 1/8 shouldnt you ? That is what i run mostly down here . I just have read some people say they swapped rears and they havent ran anybetter than with the 10bolt and it makes me wonder if there not launching correctly or waht the problems is . I went to the track for the first time last week with the new rear and i had trouble leaving the line hard enough and boged down bad at the line and still ran a .1 faster (1/8) than my times with a 10 bolt . I know with more practice with the 4.11 and laucning hard as **** i should see a drop in et becouse my mph actually gained a little on motor 
I just want to see what other people have seen out of theres and see if it is just the autos haveing the problems.
