GM does it a little different, they offer a max tow package which can be had on multiple trims and with the 5.3 and the 6.2, possibly the diesel too. But the highest tow rating is with the 6.2 as one would expect. The weight difference between engines is simply not enough to overcome the bigger...

Yes the tow rating was less than the 6.4. But that's kind of my point, gcwr is a function of the truck (suspension etc) as well as engine performance and cooling. Normally it's safe to assume an engine that makes tons more power can pull more, but thats not the case with the HO even when we try...

So we're decided then. Ram is definitely on drugs :) The rear axle ratio is supposed to be 3.92. Haven't heard about the Dana. In any case I remain skeptical about the tow ratings on these new hurricanes. I'll stick with my hemi, regardless of what the ratings are, can't put a unit on duty...

I think we're discussing two different things. Max tow is not fabricated anymore than GCWR, it's simply a calculated result using GCWR and curb weight of the lightest possible trim/truck. If you mean that the truck used in the max tow calculation for getting the curb weight, is not likely to...

Somebody a while ago posted the max tow for the SO and HO. I don't remember who, but it was just a marketing pic and not the actual tow charts. That's how we know the SO max tow went down vs the hemi. I will try and find it back later on if somebody else doesn't post it first. I agree that the...

GCWR is set using the J2807, which I know you know. The question is, why is the GCWR not higher for the HO? We know the J2807 has tests for acceleration and for not overheating while pulling up the davis dam etc. I think you're saying the GCWR is limited not by those tests but by...

As a further point re: max tow, the max tow went down using the SO vs the hemi. Yet it has more power and its a lighter engine. So either the tradesman grew fat over 2025, something changed in the J2807, or the little whizzers aren't as strong as the paper suggests, or there are cooling issues...

My criticism and objection of the hurricane isn't based on feelings, so that's not going to change after driving one. I have no doubt it feels faster and really smooth. I'd probably enjoy this engine in an updated challenger with a stick shift though even there I'd buy the 6.4 scat pack first if...

I don't agree. Yes the truck is a little heavier, but that would be more of an issue for payload and not max tow/GCWR. The HO is significantly more powerful than the SO and the hemi. I don't have all the numbers off the top of my head but at most there is like 800 pounds difference between a...

Trying to turn criticism into anger is your problem, not mine.

Yet we have the hemi which can't. Yes No, but you're complaining about our lack of interest and concerns with the hurricane Its you You call it whining because you're sensitive to criticism. See how that works? We're just here discussing why the hurricane is a poor choice for trucks and you...

You're missing the point which was that manufacturers don't overbuild an engine and then purposely reduce the output power. This field is very competitive and if there was room on the table for the 3.0 to put out more power with stock components, why wouldn't they? The reduced HO tow rating...

LIke I said, the 5.7 hemi does not react well to boost, just one example. The rings aren't gapped enough, and the pistons are like glass once the boost comes in. Why would they build an engine that can reliably handle 650+ hp but not put it out there? Max tow on the HO is also down vs the SO...

I don't find it that hard to believe. The 5.7 hemi will run forever unless you try and boost it past like 5 to 8 psi. Engines are built to a tolerance and 520 hp is already a lot of power per cylinder. I've heard reports about the hurricane putting out huge power numbers but I'm willing to bet...
