>LS7 7L NA V8: handbuilt, titanium components, tight service intervals, unreliable.... 505hp>Hemi 392: mass produced, budget components, regular service intervals, reliable to 125k+.... 485hpWhy was SRT so much better than any equivalent performance division (M, AMG, Shelby, etc)?
>>28799362In the Lord's year of 2018, SRT was truly ontop of the world.Too bad the Stellantichrist killed their entire department off to build more goyboxes.It seems Kuniskis is bringing them back tho.
One of those isn't powered by a Hemi and it bothers me
>>28799362Because Stellantis cars are a prime example of the rest of the car being subsidized for the sake of the motor.
>>28799788>>28799362Without wacky 'balance of power' metrics to keep your car in a race spec, your best ROI for performance was investment into the drivetrain. SRT was a great example of saying this quiet part out loud.
>>28799788imagine being a saltcuck
>>28799362I love the LS7. One of my all time favorite engines (and favorite Corvette) but I also love pissing off chevy bros when I say that a Hemi of the same displacement makes vastly more power. I'm sure there's a multitude of reasons for the modest 505hp figure from GM, and they were able to get 7.0L engines mass produced which deserves credit on its own, but a 7.0L Gen III Hemi makes 610hp on a fairly mild NA setup, lol.The 632 engine is another thing Chevy has every reason to be proud of, it makes 1,004hp NA, which will never be disrespected.The 605 Hemi makes 1,000hp NA too though, and look at how much less displacement there is..The Hemi is a legend for a reason.
>>28799371That dumb ass STLA leadership that eventually got fired managed to nearly destroy SRT. Honestly out of envy - euros can’t stand Americans making better cars for a 1/3rd of the cost and complexity.See the case of the Chrysler ME super car that got canned just because it was better than the garbage AMG was doing.>>28799884Hemis are also more reliable. High power LSs are good until they aren’t, and it’s usually a catastrophic event. Hemis, for as long as you give it fresh oil and immediately proceeds to redline it, can easily live 300k mi. My guess here is that the Hemi was a high performance design made to be high volume, instead of a high volume made to be high performance which is the case of the LS. GM’s high performance from birth V8 was the Northstar/Blackwing DOHC and we all know what happened with it.
>>28800995GM seems to have leaned a lesson with the Northstar and came up with the Current Z06, which is an impressive design, but far more exotic and rare than the Hemi. Fast forwarding 30 years, the Hemis are more likely to survive because there are many and plenty aftermarket than the flat plane GM.
>>28799362>LS7>Unreliable The forums have forever ruined the LS7 reputation.Early LS7 heads were machined incorrectly, but that was quickly fixed.After the 1st year, LS7 failure rates were 1.61%, yet every retard thinks they drop valves 100% of the time.The LS9 heads use the same valves, valve guides and springs.Even the same camshaft.Yet no one talks about LS9 dropping valves.That's because it was never an issue.392 Hemi are ok though.They can't revve to save their lives due to bad valve train and rotating assembly harmonics. Lifters die easily due to the cam location.Can't take much boost, But they pull pretty good.
>>28799884Bruh, a heads cam LS7 with supporting mods can make 600 horsepower TO the TIRES.7.0L LS absolutely RIP.I drove a 07 Z06 with a BTR cam and headers. Made 520rwhp and could hit 160+mph like to was nothing.
>>28799362the 5.7, which the 392 is based off, was originally designed as a truck motor. both are still truck motors. 5.7 for the 1/2 tons and 392 in 3/4 & 1 ton ram trucks.In any case its an understressed cast iron block pushrod overhead valve engine, so there's not a whole lot to go wrong.
>>28799362>505hp>485hpYou know I'm getting that power out of 2.0L totally stock, japanese 4 cylinders from the 80s right?With factory forged connecting rods about double the size of one from those engines, yeah?
>>28801780except you aren't
>>288017655.7's drop valve seats
>>28801799that hasn't been a problem since 2008, and was never a problem with the 6.1 or 6.4 (392) engines.
>>28799362Based as fuck. Truly the best engine ever made.
>>28801804>it was only a problem until a couple years agostellantis cope factory
>>28801780Is this 2.0 in the thread with us?
>>28799362>reliable to 125k+.Disposable consoomer garbage.Great.
>>288018292008 was almost 20 years ago anon. the key take away is - it was a manufacturing issue (like the bad roller bearings in some later eagle engines) not a design flaw of the engine. most people don't have issues but if you do and fix it you are left with an incredibly reliable engine. plenty of people have 5.7's with 250k+ miles on them with mostly just regular oil changes & standard maintenance.
>>288018516.4 hemis can easily reach 250k+
>>28801860Never seen a Hemi lifter last that long anon.Not with all that cylinder deactivation nonsense.
why continue circlejerking about "fastest" car specifically when 1) few of you own any of those 500hp cars2) $60k new tesla can do 2.9s 0-60don't you want to masturbate about engine sound or how rowing is nice instead
>>28802321Drive in track mode or sport mode. This disables MDS. I’ve seen several hemis up in that mile range.
>>28802321I've said this like a hundred times on /o/ but I'll say it again - that is complete fuddlore. lifters going bad has nothing to do w/ MDS. bad lifters affected manual transmission drivetrains too (which don't have MDS). Chrysler had a bad batch of lifters that affected somewhere from 3 to 5% of all 5.7 & 6.4 hemi motors.>t. original lifters on a 160k mile cop car w/ 7k idle hours and no lifter tick
>>28801852>2008 was almost 20 years agoStop lying on the internet, retard. 1990 was 20 years ago. And if you say anything otherwise I'll rape your whore mouth
>>28802534I don't think /o/ was this unusable in 2010
>>28802534anon, I...
>>28801525It's a lot lighter than a Hemi too, there's a lot of benefits. I think the LS7 may still be one of the lightest high displacement V8 engines ever made.
>>28802321I'm on 88k miles with my 5.7 and I don't hear any ticking besides some injector noise.
>>28802524Anon....>>28802527The hemi has shit valve train harmonics That's the big reason the lifters and chain tend to break.
>>28802357>I own one of these 500hp cars>plaids get fucking raped by 40k twin turbo work trucksSo to conclude, you’re indian and you’re gay.
>>28802695>plaids get fucking raped by 40k twin turbo work truckswat>you’re indian and you’re gayweird cope
>>28799362Loved my 392 when I had it. It’s a fantastic motor and all that torque down low makes the weight disappear. Having said that, the LS7 is in a league of its own. It was the high water mark of the naturally aspirated GM small blocks. Back in the day stock to stock, they were walking Gallardos, 430s and Vipers. Fast forward to today and a H/C/I LS7 car will hurt some feelings of Hellcat, GT500 and C7 Z owners. >t.Hellcat owner
>>28802695if you buy a factory turbo pickup truck the only raping is what happens to you at the service department. every single one of them is throwaway garbage. lease, don't buy
>>28802357>$60k new tesla can do 2.9s 0-60 *With more than half the battery removed
>>28803679>$60k new tesla can do 2.9s 0-60 *With more than half the battery removedwhat does it mean
>>28802321Just my views and opinions as a FCA tech of 20 years.The HEMI lifter failure has nothing to do with MDS. I've seen both have failures equally. I'ts a combination of using lower oil viscosity, customers not changing their oil regular, and a long run of china parts without the proper heat treatments.It got so bad that FCA changed their suppliers to Europe (I believe a factory in Germany). Notably its been mostly the 5.7L engines. it's rare to see any 6.4L engines that had lifter issues. Probably because they run 0w40 synthetic oil.The best fix is run 5w30 synthetic oil, Valvoline & Pennzoil platinum/ultra platinum (even NAPA brand synthetic - which is made by Valvoline) are my usual recommendations. This also goes for the 3.6L V6. Over the years, I've seen a correlation between thinner oils and a increase of mechanical failures. Those that switched to 5w30 synthetic haven't seen any issues since. >>28802677>The hemi has shit valve train harmonicsThat's the big reason the lifters and chain tend to break.The only timing chain breaks were those covered in a recall a decade ago (I did a few dozen of them on cop cars, only seen 3 that actually failed), now they use metal timing chain guides.
>>28800995I remember Modern Red Hemi made an 800hp Procharged 5.7L Challenger that only coughed glitter because he didn't get a good oil pump
huh, if you squint a bit the charger looks like an alfa
>>28802321>>28803740None of this stuff ever affected Hellcat engines.They already started with metal chain guides, improved oil pump, strict oil selection (only two certified models), improved oil filtering and many more improvements.Only known issue with Hellcat engine-IHI-built 2.3L supercharger main bearing: premature failure. Affected MY 2015 (first year) and mid-2017. Easy fix and one can take the opportunity to upgrade to a Red Eye SC.
>>28799362>Why was SRT so much better than any equivalent performance division (M, AMG, Shelby, etc)?the ford mustang and vetto walk it thoeven tho that non turbo v8 vette is garb engine build quality at least its cheap
>>28801521i enjoying bullying v6 as much as the next man, but 1.6% is fairly high considering most of the cars were seldomly driven hard.
