Traction Control and 3.91's

[Heads-up]

For those of you running higher horsepower or lower gears, how well does the traction control work with performance radials (not drag) on the street?
I am installing rear suspension mods/bushing etc. from BMR and drag radials
on the strip. CAI and LT headers will be going on this year. Considering adding 3.73's to my automatic trans car when i install the Eaton True-Trac.

I just bought my car in February and given the weather in Montana haven't played around much with the traction control. I assume it still works with higher horsepower or lower gears but it would still take off fairly slowly under full throttle as it pulls power when the tires slip. Can you roll into full throttle and still accelerate hard without slipping? Currently the car is faster in the 1/4 mile with Traction Control on due to the cold weather and winter tires. I really don't want it to break the tires loose when i shift down to pass someone on the highway.

For normal driving in town and on the interstate does the traction control work fairly similarly to the way it does stock (reasonable acceleration but slower off the line than when using drag radials)?

Traction control will only go so far. If you keep your foot in it. it will keep going. It will just slow it down.

You can roll into throttle without losing traction with or without traction control. That depends on how well you know your car.

If you are running a lot of power, do you really need to downshift to complete a pass. My car will pull hard enough in 6th to make highway passes unless someone thinks we are in a race, and then I have to decide if we are really in a race or not. Generally not.

Traction control from a dig just slows you down. My personal expirence: I jumped out on a 10 speed mustang by a car with traction off and it dead hooked. Won by a car. We sat for a while and we made another hit, I forgot to turn traction off, and it just flashed at me all the way through 1st gear for no reason because it dead hooked. We were dead even off the line and he got me by a half car.

I think that with stock tuning you will be fine with the traction control on taking off from a dig or especially on passing. The traction control will pull timing and close the throttle to limit power in a traction control issue. I seriously doubt that you can even break the tires loose on passing unless it's wet out and even then your traction control will kick in pretty fast. Now if you turn off your traction control that's a whole nother story.

3.91s ftw.

391 is a great mod. Would like to have something that disables traction control permanantly. Even shutting mine off the proper way, for some odd reason it stills kicks in every once and a while

Jannetty offered me 4 choices for my new forged Eaton TruTrak rear:

3.45
3.73
3.91
4.11

I already have 3.91’s but adding 400+ horsepower I was considering 3.73 but even Ted said stick with the 3.91’s.

Yup. Matching the cams power band to the engines rpm is important. Your gearing helps if you choose correctly.
I didn't even do the Eaton, just a swap. My car is definitely a factory freak. It takes a beating and just doesn't look back.
