Someone please help. I understand how a 3.55 and a 4.10 differ, but I do not know the extent of the effects on times and top end speeds. I realize a 4.10 produces better 0-60 and 1/4 mile times at the sacrifice of top end. Could someone fill in the blanks below with accurate information? I am more concerned with 0-60 and 1/4 mile times but still would like to have a decent top end, maybe 145 or so. I have ordered my 2005 GT with the 3.55's, 5 speed manual. Hopefully someone out there has swapped them out and timed it each way. Thanks guys.


3.55's

0-60 -- 5.2 sec
1/4 mile -- 13.8 @ 102 (or something close to that)
Top Speed -- 149 (governor limited), 160+/- @ redline, top gear

4.10's

0-60 -- _______
1/4 mile -- _______
Top Speed -- _______

 

To my knowledge only one guy has put 4.10's in so far (I believe it was an auto) and no one has gone to the track with them yet so there is no way to accurately answer your questions.

 

I've got the 4.10's in mine and will be at the local 1/8th mile track before xmas and will post results soon after......dyno is set for the 18th.....
