Correct me if I am wrong, but if you've got an auto and you mash on the gas, that baby's going to drop to <insert low gear here>, the RPMs are going to go to <insert high RPM here>, and the car's going to take off like a rocket. If you are mashing the pedal enough to "[throw] your head back against the headrest immediately", then I highly doubt you're at 2k RPMs for more than a split second...

I think the issue (and I have seen it with my car, too) is that where with some vehicles you can lug down quite a big and still have some power, these cars are pretty useless. Now maybe autos are doing this too, but if the computer is anywhere near smart it will be shifting to another gear before you really notice it.

You are absolutely correct. Most of the others in this post are probably manual GTs.

Also autos have something called torque converter flash stall in their favor. The slippage in the converter will let the tach rise higher into the powerband under sudden WOT and actually help low end torque by acting like a torque multiplier.

I think it is a combo of slow reacting throttle response and poor low end torque.

Also, HP down low is a useless measure. 100 HP at 2000 rpm is actually 250 ft-lbs of torque which aint bad.

But in comparison to a modest big block.

At 2000 rpm my 451ci mopar is making approx 465 ft-lbs.

So in reality, we are still torque deficient. And that is what makes the car move at low engine speeds.

nah man its more than torque deficiency. i rode in a buddy's 5.0 when it was bone stock, it didnt lag NEARLY as bad. not even close. i know what torque deficiency is; this isn't torque deficiency. cause while our cars pale compared to huge big blocks and such, they're not exactly lacking in low end torque. theres something else goin on here. try this: get started in first gear, and then let the car slow to idle speed. floor it. see what happens. NOTHING.


you notice the lesser torque when u shift to second and floor it at like 2500 RPM. the thing that happens in first gear, thats a goddamn electronic nanny. its embarassing. some kid in a modded to high hell civic and revved for a long as time at a light, then launched. i didnt want to appear to be trying too hard, so i took off normally, then floored it. EMBARASSING. took me till the end of the intersection to take him. i had to wait like .5 second for the power to come on. its goddamn frustrating.

remember kiddies, HP=torque x RPM divided by 5252

I completely agree. Ford created a stock v8 that is tuned to achieve a good mpg rating. I imagine that it would be hard to sell a car with a window sticker that illustrated a crappy mpg rating. If you actually read the Ford Manual (Like anyone probably did except for me) Ford provides a recommended shift range for the car to achieve optimal fuel consumption. I believe that all of these shift ranges are right below 2500 RPM.

I don't think it's just a low torque rating. Something sounds like it's clogged maybe? I would take it to the delear and see if they can find anything.

See if doing the following improves things:

1- Disconnect the battery's negative cable for 10 seconds, and reconnect.

2- Turn the ignition key to the ON position(not the ACC position, and do not start the engine),
and wait for the dash warning lights to go out and the chime to stop.

3- Press the gas pedal all the way down in one smooth motion(approx. 2-3 seconds to hit
the floor).

4- Quickly release the gas pedal as soon as it hits the floor.

5- Turn off the ignition, and wait 5 seconds.

6- Start the engine normally, and drive.

Steps 2-5 may have to be repeated 3 times in order for the ECU to re-train the
throttle variable switch and the throttle body servo motor.

hmmm..... thats interesting, ill give it a try. not quite sure how/if itll work, but hey its worth a shot.

TexStang06

hey Americanmuscle,
Did the the above procedure work for you???? Just curious...If it did I might go out and do it again....I've done it once before and noticed no difference.
