5.0 coyote low end torque...or lack thereof?

[Chargersfan81]

Honestly you guys have been spoiled by fast cars if you think it's lacking torque. Try driving a 4 cylinder Accord around for a while.

LOL Hilarious!

Well I never really noticed the lack of torque until I drove a 6th Gen Camaro. SOB had torque on top of torque to redline. With that said, I like how the PP with 3.73 gears felt. Felt very lively and with the shorter gears it def. goes into the powerband quicker. If I had to do it over I would have def. got the PP :(

Ford's tune will def help out and can't wait to hear feedback!

I thought LT headers were only a top end adder?

Mostly, yes. The tuned required to go with them will get you a big dose of torque.

My tune didn't change after adding headers. Lund disabled the rear o2 sensor right from the get go - pretty sure that is the only 'header specific' thing that they do to their tunes.

I don’t think a lot of you are thinking about this in the right context. While it’s true that the coyote motor is low on torque when compared to its Camaro counterpart, you have to look at the gearing to get the whole picture. Case in point, the Camaro has a first gear ratio of 2.66. Given it’s typical 3.73 gears, your final drive ratio in first comes out to 9.922. Using dyno numbers floating on the net, the Camaro makes 340 RWTQ at 2000 rpm. Multiply final drive by torque and you are looking 3373.41 final drive TQ. Doing the same calculation for the mustang using it’s 3.657 first gear and 3.73 rear gets you to 3751 final drive TQ. This continues through the powerband. My point is, if you don’t like the torque you are feeling, you are in the wrong gear, and/or at the wrong RPM.

My built 408W in my 94GT has massive amounts of torque, and even it in 5th gear does not feel earth shattering. My stock 2.73 gears are the culprit of that.

Some other food for thought, given the 3.73 PP gears and the 3.657 first gear ratio…were running around with the equivalent drive ratio the foxbody and new edge mustangs had with 4.10s.

edit:

This really applies to the mustangs optioned with 3.73's. For those of you with the taller gearing, you are stuck with having a final drive torque in 1st-4th nearly identical to that of the 6th gen Camaro (1st-3rd).

Ive done the tune, headers etc to help increase power on my car. Nothing really helped its down low grunt and part throttle acceleration.
Now as others have stated, adding a PD blower fixes everything.
While im NOT IN BOOST, partial throttle in the lower RPM feels more like my old Pushrod engines.
There's actually useable power down low. My KB really changed the car 100% and now it seriously drives better than stock

I have owned a couple and driven several coyote stangs since 2010 (manual/auto with all of the different rear gear options). My 2015 auto with 3.55 gears has felt the least lacking down low. I believe the 3.55 combined with the 6r80 gearing has more gear in 1st gear than the mt82/3.73. No 16' Camaro SS or scatpack but not lacking either. The auto seems to mask this issue better. You want more, put your foot down to downshift into the power band.

Stock mt82 with 3.31's feels like a 4 banger down low to me. Tuning makes the car quicker over all but doesn't do much for the low end soft character of the coyote.

The mustang is very quick with a lot of potential in any form. Embrace the way the coyote makes it's power or move on to a Camaro, scatpack, or some other option.
Going F/I like a whipple should do the trick as well.

drive a 2v, then talk about low end torque lol

My first car was a 99 GT vert. At least it was a 5 speed and not an auto but yes it lacked low end power and overall power really.

I picked up 18hp from my "header" email tune and a dyno tune. Most of the changes were made to cam timing which made a huge dif in low end and over tq. Lund tune I made 376tq with dyno tune and same mods I made 404.

Biggest gains I felt on my 2013 were low end to midrange actually. If you look at a lot of the dyno runs you'll see up to 25-30ft/lb gains from the headers alone and peak hp gains up top around 17-20 whp.

Wow! This is what I've really been wanting to hear! One of my friends is very good friends with a local tuner and he said there is no comparison between mail tunes, even logged and revised ones compared to a custom dyno tune.
I thought maybe he just had happy dyno but he's routinely been getting 425/400 out of these things with just full exhaust and intake.
Looks like its time for me to pony up for some dyno time

Geeze, I thought I was the only one that felt that! With the M6, 3.31 gears the car felt like the EB and you can't feel the pull until you go to 4k . I guess the lower gears are good if you're going to put a blower on.

The 3.73 gears with the M6 is MUCH MUCH better.

Its all in the tune, My car was over 300 ft lbs from 3k to 6k. All it has is a JLT, suitcase delete and a tune (manual car)

I wish I had a dyno sheet of my 2v GT on this PC because it made more torque than HP. My lightning, another 2v (although supercharged) made 770/880 tq and that 880 TQ was made at 3000 rpm.

Its a characteristic of head flow, the older LS1's were the same all hp no TQ, its like a supercharger or turbo, once you get out of its efficiency range it stops making big hp gains but starts making huge TQ gains, essentially all your doing is moving the power to the left.

 

[GoBlues38]

I drive mine like I drove my 3 previous turbo cars. Just keep the revs at 3,000 or better and it is all good.
