You cant really compare the 302 coyote to the 5.7 or the 5.3 because of the head configuration, a more valid comparison would be the old pushrod 302. 20 cubic
The LS3 is a 6.2L (376 cu in) 430hp and 428tq
GM's 6.0 (364 ci) was 360 hp, LS3 is 22" larger with 70 more hp.
Ram could have increased...
5.3 to 5.7 isnt neglible. The 5.3 is 325 ci and the 5.7 is 345 (the 5.0 302ci), thats 20 cubic inches (significant) and does make a difference in power.
The 5.0 makes more power and more average power due to the heads and DOHC's. The GM 6.0 is a dog too, thats why it had such a short run 6.2...
Ive seen that FB group post, the anti hurricane "mechanic" doesnt even know that the turbo isnt cast into the head or the exhaust manifoldand has said that the cylinder head, exhaust manifold and turbo are all one cast part. He also repeatedly posts the same torn down SO hurricane (in the silver...
It's also larger than the 5.3 and 5.0 (5.0 makes more power) while making similar power. It is indeed the least powerful of comparable sized engines. Up until the latest round of the L87 6.2, GM V8's have been reliable. I don't think the 5.0 has any real reliability issues either but even then...
The 6.2 is the only engine coming apart.
Dfm failures, the lifter failures are occurring in HEMIs too if you read post here.
GM engines as a whole seem to be solid but they are also innovating and not relying on a 23-year-old platform, that's why GM engines make more power get better fuel...
Its happening to one GM engine in the trucks, not all of them. There's no joy in making one update to the HEMI in 23 years and the excuse of it won't blow up is just that. There's numerous changes they could have made that would have improved the HEMI and kept it competitive; DI, increase the...
My battery maintainer on my car did the same thing. I forgot to reconnect it after the last drive and went to reflash a new tune to it about 3 weeks later, dead as he11. I connected my maintainer/charger and the battery was at 39% within about 10 min. No way it should have charged that fast...
5.7 was introduced in 2003 in both the 1500 and the 2500. 2009 was the introduction of the VVT & Eagle headed 5.7 which have been the only upgrades to the HEMI in 23 years. In that same time frame GM has introduced the Gen 1, 2, 3 & 4 LS V8's and Gen 1, 2 , 3, 4, 5 and currently has a new...
I don't see why long term towing would be an issue, towing puts more wear and stress on the transmission than the engine but like I said above, if I towed with any regularity, I likely wouldn't buy a 1500. The 10 year/100K mile warranty most definitely eases the mind though
The only thing I don't like about the HO hurricane is the mandatory 3.92 gear. I think the 3.55 should have been a option and likely a better choice; I understand the reasoning which I believe is to streamline the production line
IDK that I'd call a hurricane truck slow but I get what you're saying. Both the hurricane variants make the truck much more pleasurable to drive, no dead spots in the power curve. I've yet to tow with this truck but my HEMI truck was loud towing a 5500lb steel Maxx D trailer drop n load trailer...
Performance in this scenario is power to weight as everything else in the trucks are the same or similar so in this instance, performance is indeed speed. The Hurricane has about 10K of towing capacity vs the HEMIs 11K which isn't a huge difference. If I regularly towing either of those weights...
The HEMI offers both V8 muscle and that performance truck sound without the muscle or the performance.
I've had both and I'm not gonna lie, the HEMI exhaust note is preferable but that's it. My 20 was stock and quiet and liked it that way. The hurricane is more quiet but better in every way; I...
Well, if it bothered me enough to turn it off, I'd push the button to disable it. I've only used it (button) once to see if the 25 truck (AS/S) maintained its last state. AS/S doesn't bother me enough to even push the button.
I bought my 25 in September, it sat for 2 weeks while I still had the rental and waited for a PPF appointment, not one battery issue. Looking at this thread, the reviews of this being problem free seem mixed and it certainly is in FB groups where it's also posted. I disabled proximity on day...
