Need low end torque

Jason1320 · 03-05-2004, 06:12 PM

My stang doesn't really start to pull untill after 5000 RPM. What can I do to get more torque on the low end?

91LX2Bfast · 03-05-2004, 06:56 PM

Numerically higher rear end gears.
3.73's are a minimum, but it seems that a lot of people have been going with 4.10's lately. Several company's make a 3.90 gear also, which might be a good compromise.

Peak HP occurs at 5250 rpm and peak torque occurs 4000 rpm

I can feel my car start to pull at about 3000+ rpm and its over somewhere north of 5000 rpm

in any event you've got to 6250 rpm before the rev limiter kills the fun

Unless ur gonna go different cam, I would definately agree with the gear. Motorvation makes a 3:90 gear if ur wantin more than a 3:73 but not as much as a 4:10, but I hear lots of people braggin about the 4:10, but I agree with you the lower end needs to get a bigger sac!!! I do know this get rid of the stupid 3:27!!!!!!!

Jason1320 · 03-07-2004, 03:54 PM

I think the 3.73 is where I'm lookin'. I have to drive my car every day, I would like to keep the gas milage reasonalble. Took the car out to the track for the first time today. I found that rev limiter, not as dramatic as I thought it would be. I barley noticed right before I shifted.

blue00gt · 03-08-2004, 03:14 PM

I think you just need a supercharger :-)
With your mods your car should be almost done at over 5k, not just starting to pull.
As far as the gears go I personally think 3.73s are a waste of time. I have 4.10s and drive it on the freeway all the time to get to work and back. Go 3.90s minimum. I only noticed a 1-2 mpg loss after the change.

GodStang · 03-08-2004, 03:39 PM

If you have a 4.6 then get 4.10s for daily driver and 4.56s for drag car. 3.73 are just not worth it in a 4.6 but they are great in a 5.0.

I'm still saving up for that supercharger.

In the mean time I'm trying to get the rest of the car ready. I just odered steeda underdrive pullys and was think about the T/A kit. Problem is, I still don't fully understand how timing works and need to learn more about it first.

Thanks for the advice on the gears. Gas milage is what I was really worried about. How much trouble is it to change gears? Or if it's to hard for a novice, how much does it usually run in labor?

blue00gt · 03-08-2004, 08:00 PM

Underdrive pullies are a good mod because they add hp and torque throughout the rev range.
Timing is just when the spark plug fires relative to the piston being at top dead center in the cylinder. Advanced means that the plug fires before TDC (on the upstroke) and retarded means that it fires after TDC (on the downstroke).
I wouldn't recommend installing gears for a novice. Depending on where you live the labor could run anywhere from $150-$400 for install.

TARZAN · 03-09-2004, 01:15 PM

Go w/ 4.10's. I started w/ 3.73's, and upgraded. I actually have some 4.30's on the way now

Also, cams would help, especially a custom grind.

Pulleys may help, as well as better air flow in and out (intake and exhaust)......

Then go w/ a custom chip....

But a lower ring and pinion is your best bet. 4.10's would make you smile

go with the 4.10s
it will not kill your mpg at all I get better mpg because of the gears

you my run higher rpms on the highway but the car is not working as hard to run that high so you use a little less gas

and for the guy that said the limiter is 6250 that is not true they changed it , it is 6050 now!

i drive my car I put about 20k on my car a year(d/d) and I would have gone with 4.30s if i was not using the spray

What did you do to adjust your spedo? I have a Jet Chip and it sucks. I wouldn't mind replacing it at all. Any suggestions?

When did they change it?

The only reason I can see for this is the longer stroke on the 4.6?

The total recipocating mass of the valvetrain is much lighter than on a 5.0.

do you have a 5-speed blue? do you still reccomend 4.10s for 5spd or only for auto?

blue00gt · 03-11-2004, 02:54 PM

I have a 5-speed. 4.10s all the way.

Dallas Speed recal unit. It is about 90 bucks. Just about everyone sells it. www.Steeda.com has it for sure and www.Dallasmustangs.com also has it.

Best bang for your buck...4:10's. I think anyone here would agree that the SMILE on your face would not go away for months...I think should be anyone's first mod...the little bolt-ons help BUT, gears are the way to go...

I have decided to get the gears...now I just need to find someone to install them. The best est. I got so far is $1000, parts and labor (with spedo adjuster box). I know I can get it cheaper, I just have to wait.

Red Mustang Gt 46 · 03-13-2004, 09:21 AM

Let me guess...??? E.L.D. performance? They are expensive!!! If and when your ready to do the install, I can recommend a couple of guys who do only driveline work at Ford dealerships...if your willing to travel north east...
