RE: Ford Gas 6.2 vs 7.3

If you get the 10 speed transmission, the rear end ratio is not of great importance. It will just select a gear to get the same overall gear ratio. Then engine will have no idea what's happening past the crank shaft. The only reason to go to the 4.XX rear end is if you need that last couple thousand pounds of tow rating. I agree …. Get 3.55 gears if you’re getting a f250. If you get an F350 SRW you’ll have to get 3.73 gears. 4.30 is only of much value when you want the extra torque to start out from a stop with a heavier trailer on a hill.

RE: The world of tow vehicles would be a better place if

Biggest problem with the F450 besides the rear-end is the fact it generally has a lower cargo capacity than an equally equipped F350 since the overall Truck is heavier. That’s a whole other discussion. Technically a F-450 can carry about 450 lbs less than a similar equipped f350 but if I had a 5000 lb camper and could get 3.55 gears in a F-450, I’d sooner overload the F-450 than be “legal” on a f350. The same goes for towing ….. technically a 4x4 crew cab F-450 (with its 4.30 gears) is rated to tow a 32,600 lb gooseneck. The similar equipped F350 with 3.55 gears is rated to tow 31,300 lbs and a 4.10 equipped f350 is king with a tow rating of 34,700 lbs. Again if I had a 35,000 lb gooseneck I think I’d be pulling it with an F-450. The thing is how many people are towing 35,000 lbs? Offer 3.31 gears in a F-450 for those who tow 18,000 - 24,000 lbs.

RE: The world of tow vehicles would be a better place if

If I could get 3.31 gears in a new F450 I think I’d be ready to give a dually a go. For many applications a 4.30 final drive makes poor use of a transmission with a first gear ratio of 4.615:1 and a 10th gear ratio of .632:1. I think there are likely many people who would buy a F450 to tow a 16000 to 24,000 lb fiver if they could be purchased with 3.31 or 3.55 gears…. Maybe some Ram and GM dually guys would even give the F-450 a serious look if a higher geared final drive was offered?

RE: The world of tow vehicles would be a better place if

If F350/3500 SWR trucks were labeled F250/2500 and the 2500 series trucks were discontinued. A 3500 series truck should have duals. How exactly does fewer options make the world a better place? If you want a dually, buy a dually. If you want a SRW 1 ton, buy one. If you want a 3/4 ton, buy one. This isn't 30yrs ago when you would have to go to each individual dealer and ask for the specs on various options when it came time to purchase. It's easy to get them on the internet. If they discontinued the 1 ton SRW and included the overload spring on the 3/4 ton, people who want a 3/4 could still buy their 3/4 ton. Those who want to buy a SRW and have the ability to tow a fiver could still buy their SRW diesel.

If Ford would offer the option of a 3.31 rear axle ratio in their F450. If F350/3500 SWR trucks were labeled F250/2500 and the 2500 series trucks were discontinued. A 3500 series truck should have duals. Or how about if you could get a Powerstroke under the hood of your Ram;). Or if...

RE: Are the HP wars over?

^^^ Yup, I guess an F450 cruising empty down the highway at 75 mph is a pretty good example of wasted rpm.... especially prior to the 10 speed.

I do or my cruise control does on every long 6% grade it meets towing 35k combined. Does nothing to harm it. Engine and trans stay nice and cool. The Ike averages 7%...and it burns a lot of fuel keeping the hammer down that hard. From the few times that I have driven it, I would say you are wildly out of the norm pulling that kind of weight without backing off a bit. The boys from FLT say the Ike is an 8 mile, 7% grade but in reality it is only a 7.8 mile stretch with an average grade of 5.6%. The Ram might have saved 1/3 gal of fuel by slowing down to 1800 rpm on an 8 mile grade but a diesel engine is fairly efficient when it is working hard with your foot to the floor. The worst situation to avoid if you want to save fuel is running high rpm and light load.

My ‘22 finally got slotted a build date. I guess I’ll be replacing both water pumps all four tires and getting an oil change here in a couple months!

RE: Are the HP wars over?

I think if I was going to have my truck custom tuned I’d leave the power at 475 and bump the torque up to about 1200 lbft …. That would give it a similar torque rise as what the current Cummins has.

RE: Are the HP wars over?

The promised 505 hp Duramax for 2023 was short lived: Click At the end of the day, all these trucks are pulling Ike within what... a minute of each other? That is one of the worst pulling conditions that most truck drivers won't encounter in their lifetimes anyway. Its been clear to me for some time now that all 3 HD pickups are plenty powerful. Its up to the individual purchaser to find the one that works for them. For me, right now, its a Ram with something puny like 370 hp and 800 lb/ft torque. Somehow that is enough for everything I need. My next truck in 5 years... who knows. I have confidence that any of them will have plenty of power. It will come down to comfort, price and wife approving the looks and features. I agree with you that all three make enough power to satisfy most RVers. However on the Ike run the fact that the Ford was nearly a mile ahead of the other two after 8 miles is very impressive. What was the diff ratio on the RAM? Seems like they never get each brands best. The Ram was 4.10. Ford was 3.55 and the GM was 3.42. As I recall the GM 10 speed kept the engine at fairly high rpm. I was surprised that it didn’t do better than it did. I don’t remember exactly when that Ike pull was done but I think it was with a 400 Hp/1000 lbft torque Cummins.

^^^ Your 2017 Ford makes about 340 hp @ 2000 rpm and 440 at 2800.

RE: Are the HP wars over?

When you consider how much fuel your ‘96 Suburban could go through in a minute and how much of that energy was turned into waste heat It wouldn’t be real surprising to discover your Suburban may require as much cooling as a ‘21 Ram/Cummins. Is that kinda the point your making?

RE: Are the HP wars over?

4x4ord said: "The Cummins only has 6 gears but because it has such a large torque rise it does just fine with the 6 gears it has" Nice to see someone that understands the Cummins works well with the existing aISIN 6 speed and does NOT need more gears. Try telling the more is better crowd that....... I have said the same many times and I am the one that should be wishing for more gears as I tow West coast at 35k combined. But I am in reality more than happy with my Medium Duty AISIN gearing. As the Powerstroke pulls down on a hill it gains about 9 lbft of torque for every 100 rpm the engine looses. Your 2015 has more torque rise than the Ford ….. it gains about 12 lbft of torque for every 100 rpm the engine looses. The new Cummins is an entirely different beast….. it gains about 29 lb ft of torque for every 100 rpm the engine slows. If your 2015 makes you smile, just imagine what a 2021 would do for you.

RE: Are the HP wars over?

400 HP is a little bit skimpy for larger RV's. You need over 500 HP to pull a large RV (20,000 lb fiver) up a 6% grade at 65 mph. I haven't been in the mountains with my 2021 Ford but my 2017 with 440 HP pulled down to about 50 mph on some hills with a 17k lb trailer in tow. Probably more of a gearing issue. If it can't get the right combination of RPM and torque, it won't reach max HP. Very rarely does any engine hit it's peak HP rating in terms of real output. But still doesn't conflict with the statement that 95% of the time, you can pick your speed. Also you are probably flying by the trucks in the right lane at 50mph. Gearing isn’t so much an issue anymore but the Powerstroke would actually stand to gain more with additional gears than the Ram. The new Powerstroke with the 10 speed has a bit of a jump going from 7th to 6th, so, it will pull down to about 2050 rpm before dropping into 6th. At 2050 it is making about 395 hp. So the Powerstroke runs between 395 and 475 hp. The Cummins only has 6 gears but because it has such a large torque rise it does just fine with the 6 gears it has. The Cummins/ Aisin can drop to 3rd gear at 2100 rpm bringing the engine up to just over 2800 rpm. At 2100 rpm the Cummins is able to produce 395 hp. So with only 6 gears it can operate in the narrow power window of 395 to 420 hp. Edit: This is assuming the Cummins makes its 420 peak hp at 2800 and 1075 peak torque at 1800 and the Powerstroke making its peak 475 HP at 2600 and 1050 peak torque at 1600 rpm.

RE: Are the HP wars over?

The Ford does have a significantly larger cooling system than Ram, as well, the Ford is a little more fuel efficient (more of the fuel's energy is being harnessed to do usable work which puts a little less demand on the cooling system) so it should outperform the Cummins on a hot day. It would be interesting to see. I know my 15's cooling system is not as large as the newer RAM's but towing 35k up long 6% grades in 90 degree weather nothing ever gets close to being hot. It would be interesting to see all three towing on HOT days for sure. The coolant capacity of the ‘21 Ram is very similar to that of your ‘15 …. about 22 quarts. Are you aware of anything in particular that Ram has changed, as far as the cooling system goes, in the new trucks? Are you basing the size of the cooling system on the amount of coolant? The amount of coolant is only one part size of the radiator plays big part in in cooling. Do you have information on radiator sizes for the Ford and Ram? I know our 2016 doesn’t get hot even towing above 100 degrees. I don’t know the size of the 2020 Ram radiator core but 2013-2018 was 26.75 x 22 inches and the 2015 Ram has a coolant capacity of 22.8 quarts. The 2020 Ram has a coolant capacity of 22 quarts. The 2020 Ford has two cooling systems. The primary system has a cooling capacity of 32 quarts. The primary radiator has a core size of 27.75” x 38.38”. The primary radiator is responsible for engine coolant, engine oil cooler and the EGR. The secondary system looks after the aftercooler, transmission cooler, and fuel cooler. The Ford stacks their radiators one behind the other and utilizes a high capacity fan in order to draw through an adequate amount of air. I’ve heard people say that towing very heavy up long steep grades on a hot day will cause the Powerstroke to derate but I’ve never experienced it.
