hey i have a 04 mustang 3.9L and i was wondering how much gears and tlok will help, im thinkin 4.10 gears, i have a cai and bbk throttle body, what would my 0-60 be in a general area?

well first off gears will improve your acceleration quite a bit. ive only been in one car with 3.73 gears my friends 2001 gt and it made a world of difference in acceleration i was being pushed back hard into the seat. tlok will evenly send torque to both wheels which will mean no more one wheel burnout which surely will help your launch and traction. as for the 0-60 i have no clue. but your top speed will go down a bit and highway driving wont give as good of gas mileage as your used to since your rpms will be higher than they used to be at the same speed. if you have a standard go with 3.73 but if its auto go 4.10. i believe thats the way most people have it but if you want 4.10's why the hell not?

I eventually want to get gears, tlok, and lt's, but i have v6 magnaflows right now so ill have to have someone fabricate a h pipe for me. with gears, full exhaust, cai, and throttle body, will i be able to stay w stock mustang gt's?

dont quote me on this but with all of your bolt ons you could more than likely keep up with a gt.
but to get you started heres some things



exhaust
t-lok and gears
underdrive pulleys
SCT Xcal 2 tune

and then you could get this stuff to
distributor
spark plug wires
throttle body
MAF

but just as with any of the other posts if you really want to make your car mean then you'll of couse want to do the aforementioned mods but also the 4.2L stroker kit and possibly a supercharger. but if you go with all that you will want to get the 8.8 rearend off the gt along with the 3.73 gears. so if you plan on extensively modding it then go with the 8.8

hey thanks for the help, i most likely wont stroke it or supercharge it, just cuz im going to college in a year and wont have time, but i want to get a lil more hp and a lil more throwing me back in my seat feel, so im thinking some gears and tlok, and lt's for now, maybe some ud's as well, but again, thanks for the help man

[232stang]

no problem. im in the same situation with college and what not. good luck on it.

gears will be the most noticable difference you do to your car of your bolt ons
full bolt ons with gears and t-lok will keep you up with the GTs maybe beat em depends on how good you drive.
if you include heads as a bolt on then you'll smoke GT's

ive driven a v6 with 4.10s and 3.73....me personally i want 3.90s.4,.10s on a manual IMO first gear is pointless and a PITA to me...but 3.73s are satisfying but i know after a while i'll wana go more...so 3.90s will be fine

idk what your new 0-60 will be but it'll be different, gears have been sed to take off about .5 a second on your 1/4 times

gears alone will not be enough to beat new edge GT mustangs, but you will be substantially quicker throughout the powerband with a steeper gear such as a 4.10:1 ratio. i have 4.10s and love them, but i do not even know my 0-60. i never ran a 0-60, just a 1/4 mile drag...
