Large coolant system, large brakes, a truck heavier than the trailer so you’re not getting ripped around helps the tow go nicely, I tow stuff all over the Sierra Nevadas in a 12v Cummins and have no issues other than my transmission exploding twice, finally got rid of that shitty nv4500 and swapped a ZF6 in with external cooler so that problem is solved

He's not saying you "need 1000lbft to tow" he's saying that using hp as a metric to evaluate towing is wrong and torque is the important thing to focus on. First guy is trying to imply the Armada is more capable for towing because it makes more power than a turbo diesel. Second guy corrected him by saying torque is the number to look at, where turbo diesels have 1000lbft which is far more than the Nissan, therefore making their engines far more suited for towing

>torque
Its actually about horsepower. The tow engine needs to make good specific output horsepower *at an RPM low and comfortable enough to stay at for hours*. This means big, low end torque, and why people always associate big torque with engines that haul, but it's really about having the HP at the correct, suitable RPM

I love whenever the torque vs horsepower /o/tism argument comes around because it's such a funny filter for people who understands power intuitively vs what they've been told. Power is torque over time, they are intrinsically related. To tow an object, the engine configuration is actually unsubstantial to the whole argument, the real talk up be focused on the transmission, the mechanical device that can convert power into torque

This.
You could tow with a gas turbine (high RPM, low torque at the shaft), if the transmission is able to get enough torque to the wheels.
The engine must be able to provide the necessary power over long periods of time (cooling!) not only for a short sprint.

Wym? I drive brand new late model cars, these are just projects for fun, I do engine and transmission swaps constantly and solely for fun and enjoyment, it’s a hobby
Dunno why 4chan isn’t letting me post images rn, I’ll try again later I have engine swaps to do right now and I’m not even kidding

I think 1000 should be the minimum for a pickup now. One time I bought a truck and it only had 660 and it was horrible. Immediately tuned that fucker to where it should be and it’s wonderful with a load behind it. Of course this is a retarded thread of a retarded redditor and a retarded OP so I don’t know why I’m even saying this.

More torque does not make an engine more suited for towing. Retards think it does because they see big diesels in semis towing things and big diesels have a lot of torque as a result of being low-revving. It's duty cycle that's relevant for towing, and it's entirely possible for a lower-torque engine to have a higher duty cycle than a higher-torque engine. I'd take a naturally aspirated 6.9 IDI with 315 ft-lbs over an F1 V6 with 650 ft-lbs for towing, for example.

Why are you Euros so ignorant of the towing requirements in Europe vs the developed world? We have thing thing called tongue weight here which requires a heavier duty vehicle to handle that. You're expected to tow shit at 80mph here, not 80km/h. That requires a lot of torque AND HP. Then there's the actual loads. Lake boats can be well over 5000lbs and even the smaller travel trailers can be well over that despite being garbage quality rolling Ikea furniture.

Because most places if you’re not going that fast some retard will eventually come flying up behind you and tear end you because they’re watching TikTok’s while driving

Power IS torque x RPM.
You need the torque at the wheels not (necessarily) at the crankshaft.
So you need sustained (constant) power from the engine (because you want to tow over long distances not only for a short while, like passing) and a transmission that converts this power to torque at the wheels (which further convert it into pulling force at the trailer hitch).

>You need the torque at the wheels not (necessarily) at the crankshaft.
You can't make up for a lack of a TQ from and engine with gearing. Sure you could move a semi truck with your moms vibrator motor if you used enough gearing but you're going to be moving at 0.0005 mph. To move big and heavy things quickly you need TQ AND HP (from the engine).

>You can't make up for a lack of a TQ
Lol yes you can, that's the whole point of the transmission
>you need TQ AND HP (from the engine)
Having torque down low is the same as having horsepower down low, if you don't understand this concept, you don't understand power. You don't need a lot of engine torque if you can multiply it with the transmission but to tow at a fast rate, you do need a lot of horsepower. Having a lot of horsepower down low is an important factor in towing at highway speeds for extended periods of time not because of capacity or capability but for duty cycle, building a lot of horsepower up top instead of down low produces a lot of heat and wear.

found a p pump 12 valve with only 150k on it for the donor engine

Sure you can. Power is just the product of torque and rpm, a transmission can transform one into the other.
The vibrato motor's problem is low power, not low torque.
You can even run a main battle tank with a turbine (relatively low torque, very high RPM) given the right transmission.
