Help: Which gears to buy?

[HogStang]

What's wrong with the 3.90's? I've seen some people on this forum, actually alot, who've got the 3.73's and they said it's just fine.. Besides, I don't want my RPM's to go nuts when I'm freeway driving at 70-80 mph. It'll get way too annoying with my American Thunder. And right now I just want a better launch, becuase to be honest, the stock gears blow, so I'll survive with the 3.90's I think.

What are the stock ratios on most Mustangs?

 

[HogStang]

3.23 if I'm not mistaking.

i love my 4.10's but i almost wonder if the 3.73's might have been a better choice.. gl on whatever you choose

stock is 3.27

plain and simple, im getting a Procharger..3.73s, only the fast cars on stangnet have 3.73s, ie. the ones running 10's and 11's

Well, 3.90's aren't that much different from the 3.73's are they?

Easy answer to this question: If you plan to go fast, go 3:73 (supercharged).. If you are making less than 350 HP, then go 4:10s..

And where exactly will the 3.90's fall into place? Are they atleast decent? Will I notice a big acceleration difference? I was going to go with the 3.73's but the guy at partshopper told me the 3.90's were selling like hotcakes and from customer reviews performed better then the 3.73's. Does anyone here have 3.90's? Becuase I know they just recently came out...

friend has a procharger with the intercooler. around 10psi with SCT tune and 3.73's. Pulls very nicely. I was expecting more. Maybe i'm a power freak.
