4:10, T-Lok, U-D Pulley

dgt_mustang · November 11th, 2007, 07:09 PM

i hear these three things

4:10, t-lok, u-d pulley

are pretty good mods to make, why is that?
whats a t-lok?
whats a u-d pulley?
Im pretty sure i know 4:10 is the gears you should switch to but does it really give you better acceleration?

HMUSN · November 11th, 2007, 07:12 PM

4:10's will make you accelerate a hell of a lot faster.
a T-lock is so both tires get power instead of just one resulting in better traction
U/D pulleys free up some more power out of your engine because they are smaller than you stock pulleys and it's easier for your engine to accl.

dgt_mustang · November 11th, 2007, 07:17 PM

are these hard to put on or pretty easy?

BWAL09 · November 11th, 2007, 07:18 PM

the underdrive pulleys will be easy, but i'd recommend you take your car to a shop to have the gears installed, and you might as well have them install the t-lock while the rearend is apart too

HMUSN · November 11th, 2007, 07:18 PM

the U/D pulleys are simple.

I wouldn't do the gears/T-lock yourself though.

what kind of gas mileage am i looking at if i put the gears on?

in performance? or gas mileage?

dgt_mustang · November 11th, 2007, 07:24 PM

so should i be doing anything different before the gears and u-pulley? i have mac long-tube headers coming in, exhaust is getting dualed out with cats getting cut off, CAI already installed, should i go with t-lok, and gears, as well as u-d pulleys next?

sounds like a good plan to me

dgt_mustang · November 11th, 2007, 07:27 PM

great, sounds like im doing it then, everything else is stock though on the car, any good websites you guys recommend to get these then?

dgt_mustang · November 11th, 2007, 07:38 PM

the post i went to read from that link at the top says that you lose some top speed, that true?

BWAL09 · November 11th, 2007, 07:40 PM

yes

dgt_mustang · November 11th, 2007, 07:43 PM

any idea by how much or is it really minimal? the car speedometer goes to 120 i dont want to feel to limited there.

HMUSN · November 11th, 2007, 07:45 PM

you don't have enough power to worry about it.
your top speed won't be affected.

dgt_mustang · November 11th, 2007, 07:47 PM

what brand you recommend for the gears?

HMUSN · November 11th, 2007, 07:49 PM

they are all the same pretty much.

people tend to lean towards FRPP because they seem to be the easier install for the mech.

dgt_mustang · November 11th, 2007, 07:50 PM

i went to american muscle to look for the underdrive pulleys but they dont seem to have ones for the 3.8L,

HMUSN · November 11th, 2007, 07:51 PM

they don't have a lot of stuff for the 3.8

chec k with the v6 crowd.. they will know some good websites.
