Tired of hearing 5.0 all over this Forum

[cbass]

I wouldn't call a 5.0 "just a fanboy engine" as some have suggested. They're getting 390tq, 420hp out of 4.951 liters. They have power everywhere in the RPM range, run as smooth as any Lincoln or Cadillac anywhere in the RPM range, and while I know we don't buy cars like these for fuel economy, it is still a bonus to be able to get around 30 MPG from a 400+ hp engine with the cruise set on the interstate, as mine does.

The 5.0 engine is an amazing piece of engineering getting 420 hp out of 5L with great fuel economy. However, no matter how amazing it is and how much technology has been put in for all "practical" purposes the LS3 still has higher peak output, more power throughout 90-95% of the powerband due to a 1.2L advantage, slightly less weight although it's close, is more compact for easier fitment, and essentially returns the same fuel economy.

The mustang is a faster car right now, but I still think the LS3 engine no matter if it uses pushrods and doesn't have x/L hp output is still the better engine.

I still can't wait to see what the 5.0 will be able to do direct injected.

And just curious, at what speed are you able to pull off 30 mpg?

Oh really? Ok, well then let's do a 4 valve 6.2L with VVT for comparison. It's not fair to compare 2 valves/cyl to 4 valves/cyl.

That's because it's in a truck. If I am not mistaken the F150 also uses the coyote 5.0, but in the F150 it makes 360hp @ 5500 rpm and 380 tq @ 4250 rpm. The "little" 3.5 L, although giving up 1.5L does 365hp @ 5000 rpm and 420 tq @ 2500 rpm. And that's from just 6 cylinders! Imagine if it had 8 cylinders!

Yes... yes I do!!! LOL!

Ok... I have run PLENTY of STOCK SS Camaros at the track... and I have run a few 5.0s. I don't care what anyone says or thinks, but I seem to easily beat the STOCK Camaros while, the 5.0s not so much....

I don't know what it is, but the Mustang simply seems easier to get down the track! I watch the newbies at the track... The new guy with his Camaro seems to struggle and runs mid to upper 13s... Just check the threads in the Drag Racing Section... On the newbie Mustang guy on the other hand makes one or two 13 seconds passes and then the next thing you know he's well into the 12s!

The Coyote engine is cool.... But as for me... ECOBOOST ALL THE WAY!!! LOL!

This.

I actually kinda agree. I drove both before making a difficult final decision, and good as the 5.0 is, I found the LS3 to have an even better torque curve. (I ended up going the Ford route for other reasons).

They should have done it right out of the box in 2011. All the engineering work was done. There is even a little nub on the bottom of the head that is clearly the spot the direct injector will go once its there. They just decided to save the money for now and not include it. I'd rather they spent money on that than on Sync.

About 70. I usually set the cruise around 5 over. Admittedly, I'd never be able to get 30 in Chicago where you are given all the congestion and the lousy excuse for fuel that the EPA passes off as gasoline and forces on drivers there. The fuel I burn is pure, 100% gasoline (well, almost).

Again, let's turbocharge the 8 cylinder and see what ha;ppens. Also, considering ford has a 2 valve 6.2 without the Mustangs trick VVT making 412 HP already, imagine what a 6.2 4 valve with the 5.0s trick tech would do, 475, 500 HP on a very conservative tune?

That's because the EcoBoost is incredibly detuned from the factory! With JUST a tune were at just over 400 HP and 450 TQ!

Why waste time on the coyote? The S2000 motor in the Honda's made 120 hp/L naturally aspirated and it was only a 2L 4 cylinder. At 4 L it would have been 480 hp and that's still 1L smaller than the 5L on the mustang with half the cylinders!

It was actually a hard choice for me between a camaro and the 5.0 and I won't lie it was very close. I almost ended up in a mustang. I will probably get banned from camaro5 soon for saying that. I still think the mustang offers a great value for your money.

Direct injected I think the motor will be very potent. I could see it pushing over 450hp easily. I can't wait to see what the next generation coyote brings along with the Gen V v8. It's impressive they were able to squeeze that much power out of the 5.0 without having to use direct injection.

Admittedly, I'd never be able to get 30 in Chicago where you are given all the congestion and the lousy excuse for fuel that the EPA passes off as gasoline and forces on drivers there. The fuel I burn is pure, 100% gasoline (well, almost).

Ya....the gasoline around here is crap. The few times I managed to actually put gasoline is one of my vehicles and not an ethanol mix I was able to see impressive mpg increases. Ethanol is crap. Chicago stop lights are also poorly timed.

Oh, i know, know there are a few ponies to pick up on the 5.0 too with a tune, but here we are speaking strictly stock Besides, that is true of most performance turbo motors these days.

You are totally missing the point......... I don't give a flying rats ass about hp per liter, just the HP a motor is capable of. Again, you are only comparing the base 5.0, what about the boss 5.0? And why do you keep going to turbo 6s, small high revving 9000 rpm 4 cylinders that make no torque, it really isn't comparable, yes using that logic it may have 480 HP, but 200 pound feet of torque, not even in the same ballpark., at least keep it V8 to V8. the point is the 5.0 is not only challenging the LS3 in HP, but isn't too far off with torque and it is not running anytype of power adder. now if you want to really get into scematics, BMW had a 400 HP 5 liter V8 in 2000......

I'd imagine a directly injected 5.0 would be closer to 475/500 as the boss already makes 444.

I'm very interested to see what GM can do when the make another OHC motor, and make it performance oriented.

Not that I have anything bad to say about their current line up aside from some LSA power issues.
