That's me. I drive 55 mph. I know I hit 80 today but only in the interrest of science. Even though I'll prolly never do it again holding my phone.

 

Look I don't know how else to say it. I never said I got to the "engines" redline. I never said the engines couldn't rev over 5k. What I said the rev limiter was set at 5k. Yall can play w/ words all yall want. This whole conversation was based on 5k rpms. It was I that said my mustangs wouldn't do it. I'm the one that proved myself wrong. Now I'm not going to debate what the "engines" redline is. I'm dummer than rocks but I have enough sense to know that if I got into the redline as far as I did today then that clearly isn't the redline of the engine. I've said so many times in the f150, 6.0, Super duty, and even in this thread how I love the 5.4l damn good engine. So in no way would I be making it out to be weak. It just don't doesn't line up with the 6.0l and later psds. Its my opion as well as about 150,000 or so +- of other super duty buyers every year that the gas drive train isn't the best towing package. That's not saying the gas drive trains are weak or couldn't pull what a psd could.
I was asking for break cause I made a false statement and as always I'll backup what I say or admit I was wrong. Do we need to argue the engines redline. I thought everybody knew what a rev limiter was. Kinda self explainitory. Ford has only been using em for 41 years that I know of.

 

I know, I was just pointing that out.

Crown Victoria Police Interceptor.

 

I wouldn't have ever figured that one out.

 

Well, this thread is now over 250,000 veiws.

 

100,000 wanting to see you blow up your other V10... Reality is the same 50-60 people posting again and again...

 

I hope nobody blows up any engines,,,,,,,,,except perhaps a few dodge owners!

 

I found this video that may help make your point of some modulars not being able to go over 5k rpm. It's not of a SD, but it may help.

YouTube - Ram 1500 out-tows the Ford F-150

I don't think the new F150 went past 3900 rpm at WOT. After watching the video, it seems to me that the computer was limiting the F150 to not downshift and go at higher rpms.

The dodge was WOT in 2nd gear (1.50:1) at 4400 rpm.

What you do and everyone else think?

 

That Platinum 150 should have had the 6speed in it, thus reducing the chance of being stuck between gears. That said at 3500-3900 rpm its possible the stock tuning was not allowing the trans to knock down a gear however with the 6 speed the rpm difference wouldn't be as much as the 4 speed. Did they mention gearing differences at all? Ford liked to put those 3:55s in the 150. The 5.7l in the Dodge does have a noticeable horsepower advantage and was able to downshift to second.

 

they can show a dodge jumping the grand canyon for all i am concerned.
i think dodges are junk trucks, and built by a junk company. and that is why i will never own one again.
the last good dodge i drove or rode in was my 66 W-300

 

FORGET ABOUT THE CONTENST. I DIDN'T POST IT AS A DODGE VS FORD ARGUEMENT! I'm asking opinions on Exile point of some modulars limited under 5k rpms.

I posted to show ford towing rpms at WOT.

The ford 6sp has a 1.52:1 3rd ratio and the dodge has a 1.50:1 2nd gear ratio. So if the ford would have downshifted to 3rd (1.52:1) it would have been somewhere near 4400 rpms just like the dodge. Dodge had a 3.92 rear. I don't know what the ford had.

I thought maybe this would help Exile in making point.

 

I believe the 5.4L redlines just north of 5,000 RPMs; downshifting from 3,900 RPMs might have put it over that. The PCM will NOT allow a downshift to over-rev the engine.

It'll hang at redline all day long, but the speed and load have to line up so that it's possible. When we did the towing comparison and included my dad's 3V 4.6L F150, I was able to hold 6,000 RPMs in first gear as long as I wanted to. Upshift to 2nd on a 15% grade with a 10,000 lb trailer and it couldn't hold speed at 4,000 RPMs. Back down to 1st and 5,500-6,000 RPMs it went.

The computer will not limit downshifting as long as the RPMs are in the acceptable range. The 4.6L has a shorter stroke, and revs higher.

The horsepower advantage is the biggest factor, here. The Ford was out-matched by 80 horsepower; it's like comparing a 6.0L PSD to the new 6.7L PSD. Or the NPI 2V V10 to the 3V V10!

 

What do you think about what I said below. Is that possible?

 

The Ford wouldn't have had anything steeper than a 3.73 and IIRC, the towing mirrors were only available with the Max Towing Package which included / required 3.73.

 

You do make a good point. The 150 should have been able to downshift to gain more rpm as the speed declined. It could have been at WOT the 5.4l was able to keep up just enough speed to not allow the shift. If the 150 had the max to package it had 3.73s, if it didn't have the max tow it probably has 3.55s. I'm sorry to say I don't have any seat time in the 6 speed 150 nor am I familier with their shift strategy.
