Stronger exhaust springs?? To keep the muffler bearings from coming apart or something?
OMG , thanks for the laugh.
It surprises me you dont understand the need for stronger exhaust valve spring with an exhaust brake. The PacBrake kit for the old 12 valve Cummins included new stronger springs, these were needed to keep the valves seated against the back pressure.
My bad. I wasn’t thinking valve springs as the OP just said “exhaust springs”
Apologies, I now understand what he was saying.- about the only thing I saw worth any difference between the two was the fuel tank size. Extra 12 gallons in the ford is nice.
- I watched the video again particularly the Chevy down hill section and noticed the truck would maintain the speed, but then the transmission would upshift which effectively reduced RPM's and reduced the effectiveness of the exhaust brake. A programming change to the shifting strategy when in Tow/Haul mode should fix this issue IMO.
- I would have liked to see the high output Powerstroke tested against the regular output Powerstroke. I’ve got the HO ordered but after seeing that test result I’m having a hard time seeing much value in it over the regular output.

You’ll only see a grade that long and steep once or twice on your camping trip so not that important to me. What’s important to me is the ability to merge into traffic and accelerate and make a pass of a slower vehicle. The Chevy accelerated 30 to 60 quicker something that is used daily on a camping trip. The Chevy also rode smoother and had a quieter cab with the engine fan coming on less times. The Ford with 30 more HP and 200 more ft lbs. I was not impressed. And what does that High Output engine cost something like 3 K more what a ripoff.
This whole thing is just a big pissing match.
I pretty much never put the pedal to the floor and I don't do drag races with the trailer attached (or not attached for that matter)...so I don't care much about acceleration.
Being able to match or beat the semis on grades is generally good enough. Not many grades that are long enough that I care if I have to slow down to 50mph (while the trucks are doing 35mph).JCK wrote:

You said a mouthful there. I took a ride on a chunk of 2X12 plank with a milk crate nailed to the top of it, with 4 old lawnmower wheels attached to the sides built by my 8 yr old Nephew that rode better and was quieter than any Ford truck I've ever owned or driven.- You’ll only see a grade that long and steep once or twice on your camping trip so not that important to me.

- I'd never buy the GM, those 13 seconds and 5 extra brake applications reported by some Internet Douchebags are a real deal killer ROFLMAO.

I do agree Ford did it faster. 13 secs is not the end of the world towing a larger grade like this. a minute or three is worth bragging about.
So at the end, buy what seat your butt fits in best.
