Hey guys i drive an 07 auto v6. Upgrades are an airaid cold air intake and borla axleback muffler. The intake didn't require a tune so i haven't bought one yet but that will be my next upgrade in a few weeks.
Since I'm getting the tuner i figured gears and t lok would logically be the next thing so i can recalibrate my speedometer and such.
I couldn't see myself settling for 3.73's and always wanting more so if i get gears i will be getting 4.10's.
My question is, since fundamentally the lower gears will mean higher rpms, what will my new top speed be if currently it is 115 with stock 3.31 gears?
by the way... off topic but this doesnt deserve a new thread. I've been hearing some weird vibrations coming from the dash i think. Happens when i start up for about 5 or ten minutes. Has only happened with the cold weather. any ideas what it is or how to fix?

Thanks everyone
4.10 gears will lower your top speed and increase RPM's. If you plan on driving this car on the freeway, go with the 3.73 gears.
There is a formula around somewhere for that, I am sure someone will chime in.
As far as the vibration, it's a known issue that I also have. There is a TSB on it. http://www.allfordmustangs.com/forum...tml#post552484

ah see that helps. Thanks a lot to everyone. So just for the last time you believe i will still hit 115 without a problem?
Generally speaking, if you're thinking about changing the gear ratio on your car then top speed isn't part of the conversation. People lower the gear ratio to decrease acceleration times. If you're worried about reaching top speeds, keep your stock gears and spend the money on increasing your engines power output.
Somebody correct me if I am wrong, but arent the S197 V6s governed to 115-120 range because of the drive shaft? If so I would think you could still hit it.

They are governed at 113, and the driveshaft is rated at 115. When you get your tuner, you will be able to get rid of that limiter.
4.10 gears will still definitely allow you to hit 115, but if you do plan on going those speeds, you better get a new driveshaft...
does anyone know what would happen if you go over 115?
im know the gt driveshaft can handle speed up to 150+ right?
what happens with the v6? it blow up or somthing? haha i dont know but i cant really see any problem with going over that speed. someone please make me feel stupid and correct me

The S197's have a 2 piece drive shaft which don't stay balanced at speeds over 120. If the driveshaft were to break at high speeds, you'll be in big trouble. It can shoot through your floor, cause you to lose control and crash. There's a reason Ford put the governors on the V6's, to prevent people from pushing their cars into territory where they don't belong.

i knew that they were two-peice but i wasnt aware they could become so unbalanced to break apart. learn somthing new everyday right?
i think u can get a Gt driveshaft for about 80 bucks right?
anyone tried installing one? is it somthing you can do in the garage with basic tools or do u need somthing specail?

The DS being two piece doesn't have much to do with it. It's the how the u joints are attached to the shaft. The early models did not have c clips holding the u joints on. At speeds over 130 the shafts have been know to come apart. This was only an issue on earlier models. There's some youtube vids off shafts coming apart on dyno runs. Again, it's usually over 130, not 115. I doubt Ford engineers sat down and said, 'let's set it at 115 because at 115.1 that shaft is gonna blow". Pretty sure they put it at 115 due to the tires on the base model 6.
My garmin says 114 is all she has, that was bone stock. Haven't tried another run yet.
I am sorry to say I have forgotten which of the denizens of the Black Mustang Club forums made this Excel spread sheet, but it works good. If you have Excel or something that will use the file, you can add RPMs below the provided 1900. I'm not that comfortable messing with spreadsheets, so won't be much help in that regard. Although I do intend learning how. Soon.
I hope the link works. It does for me. My host decided to change a lot of things and I'm not sure I have all that figured out yet, either.
4.10 Gears Top Speed?
