5.0 Coyote vs LS3/LT1 GM engines - how do they compare?

[Higgs Boson]

Every centri c7 ive seen makes around 650-750s on about that boost with meth or e85 plus other upgrades

Fastest c7 ive seen is 9.39. It was lmr's car. That wasnt even the stock engine if i recall correctly. Based on everything ive seen it takes more boost to make similar power and is going slower in the 1/4 then the coyote. I havent been to the vette forums in 3-4 months. Unless something has changed. :shrug:

Its more then just injectors holding you guys back unless thats changed too, it was fuel the cam driven fuel pumps.

not sure. nothing has changed in 3-4 months.

I'm not building one just curious about ls3 vs lt1.

The real difference is direct injection.

Everything else is a very minor contribution.

Direct injection is the heart of the LT1 and is what truly separates it from the LS family.

That is likely the reason some may want an LS instead. The lt1 gives you a higher starting point but the LS is way easier to tune due to lack of DI.

That said, it would behove some of these companies to "leak" some info to the tuners to help them out. It's a ot of work dialing it in.

I'd love to see Ford utilize a mature form of DI soon.

But i'd also expect them to leak tuning help relating to fuel delivery. Ford is cool like that. They've done similar things before. Seem to really understand their Mustsng fan base.

At least under Mullaly. Don't know how Fields will move forward on this type of thing.

Best engine for the $$$

392 Hemi. Best Engine: 6.2L Hellcat Blown Hemi. Otherwise, I'd take a 5.0 Ford motor over any GM POS.

I do like the 5.0 but the fun factor of our '06 GTO (LS2) was tough to deny. The low end grunt is fantastic and they pull surprisingly hard on the top end too. I ran a FAST 90 and full exhaust and a couple other goodies (along with a 150 wet kit) and loved that engine. Moving to the '12 GT, I ran out of gear really fast, had no passing power in 6th on the highway (never needed to downshift in the goat), and was initially disappointed. I grew to love the top end pull of the 5.0 and accepted the differences but it really is hard to be disappointed with either engine. They're both fantastic power plants.

The LS motors have more of the old school muscle pull from low RPM. The Mustang is more refined feeling when accelerating and pulls better up top.

As far as sixth gear goes. I don't have any experience with the GTO, but the LS3 doesn't do much in sixth in the Camaro (at least stock.) Have to downshift to accomplish anything. I'm guessing it's about the same with the LT1.

5.0 pulled much better up top for sure. But sixth gear in most 6 speeds is crap, at least in any I've driven.

Agree though. Both engines are great in their own ways.

Maybe there is a language barrier for YOU to work on this :doh:, since you only babble nonsense.

Here is an output chart for the two engines published in the same magazine.

And please don't be so lame as to say that the LT1 does not reach 6500 RPM and that is what you meant. That would be stupid since peak output is archived earlier than that in the LT1. :headbonk:

Those numbers for the Mustang are obviously fudged a bit in favor of the Camaro. Even Motor Trend who are very GM biased got better numbers than that.http://www.motortrend.com/news/2015-ford-mustang-gt-first-test/
Backed up by Motorweek too,[ame]
And I would have to say alot of it has to do with the 8 speed auto over the six speed manual, automatic trans cars will be quicker most of the time when it comes to 1/4 mile times.:ford:

Lol... I always love the Motor Trend is biased excuse when a car someone doesn't like beats out another.

Ford sent that car. That's not Motor Trend's problem.

While I agree with the argument that the auto is quicker. That's not being biased. That's Ford sending that vehicle. Not to mention the auto still loses anyway in the Mustang.

I'm pretty sure when they drop a tranny with more gears and a bit more HP though the Ford will be back on top like it was all through the 5th gen war.

Those numbers are so low for the stang. I wonder if they really test them on the same day. Both independent suspension and both have wheel hop on the launch. There has to be an explanation to these results.

The MotorTrend argument is not an excuse, its just a well known fact. Anyway you missed my point here, look at the times 12.8 @ 112 and 12.9 @ 112. Now that's quite a difference from 13.2 @ 109, and .93? .give me a break R&T, more like .96.The new SS does edge out the GT PP, but not by alot, its what 20 more hp and 55 more ft lbs of torque and 78 more cubic inches gets you. The weight difference is only 50 lbs between them so thats not really a significant factor, put a 250 lb driver in the Camaro and a 200 lb driver in the Mustang and you are equal LOL! :ford:
I realize that Ford sent them the Mustang, just like GM sent them the Camaro. :doh:

 

[islander33]

Where are you getting your information for the LT1 responding way better to mods from? What are intake/tune/exhaust LT1's running in the 1/4?

Fromato ran 11.0 @ 127 in an E85/tune/DR C7

"Fact"

So where is this fact? On an Internet forum where a bunch of fanboys got together and decided it was fact..? That's not a fact.

In every review out there the Mustang was beat by the Camaro as far as basic acceleration and quarter mile times go. Comfort? Sure the Mustang will usually edge out the Camaro there. You can see out of it better too.

And most people here would argue that the Mustang is a better overall car. That's fine. It's a great car.

But numbers across the magazines don't lie. Also, there's way more to how a car accelerates besides max hp and weight. Just saying...

Now could you argue that someone who knows how to drive could make the car perform better? Sure. That is appearing in the different times you pointed out across magazines.

Edit: This shouldn't really matter anyway because very few people on here are going to be running hero times in either car.

392 Hemi. Best Engine: 6.2L Hellcat Blown Hemi.

So which is it? The 392, or the blown 6.2L?

The 3926.2cu.in/L HellHemi.

I honestly can't tell if you're serious, being funny, or even aware of that typo.
