i am just curious what is the top speed of a 3.8 liter mustang and what is a mod that would make it much faster

117mph. with GOV. Take it off with a tuner. And you could probably get it up to about 130. But it is not built for those speeds so I wouldn't reccomend you doing it.

It depends on what year you have. The 94-98 have the highest rating with the governor followed by the 99-04's, and then the 05+ are the slowest with the governor. If you take the governor off then you might be able to get 130 or a bit more like previously stated but that would be stupid. Why would you want to go that fast on 15 or 16 inch rims with 205's? I am not saying the 05+ are the slowest I am just saying that they top out the lowest.

A mod that would make your top speed muchfaster would have to be at least a turbo or supercharger. You don't sound like you know to much about cars if you just want a high top speed and you need to know how to increase it.

Some type of tire rated at high speeds SHOULD be your first thought if you wanna get to 120+

Well the 2005-2008 have weak driveshafts. If i were going to think about going over 105mph I would relpace my driveshaft. to many reports of them failing.

I wouldnt suggest pushin your car over 100mph on stock suspension

Exactly, going over 100m/h in a stock V6 starts to feel really floaty. I don't know how it would feel in my car now, but I still don't think it would feel all that comfortable. lol

Astock v6 can handle 100mph .Maybe not 150mph or130mph or even 120 mph. My carwhenstock at a 100mph it felt solid and even feels more solid now with my roush springs and tokico S/S. when i was 17 and 18 everyone was like i just hit 125mph in my truck an everyone was like cool man now everyones like its not safe and blablablablablabalba i guess times change. peace

No V6 doesnt feel solid at 100 mph. What the **** are u on. Stock suspension is crap on these cars

indisposible_teens

True about the stock suspension being crap. I have springs,shocks/struts, rear sway bar, SFC and I still don't think it would feel stable at 120+.
