Who will swap for the new 7.3 V8!

[Bluemustang]

List of power you've compared favorably to the 5.0:
- Electric motor
- 3.7 NA v6
- 2.3 ecoboost
- 7.3 gas

Hmmmm....basically anything that's not a Coyote.

You've never driven Gen3 Coyote. You've never floored a Gen2 Coyote. Have you ever floored a Coyote at all? What about one with a tune? Doesn't matter because you just don't like the Coyote.

I was looking at some old car quarter mile times and it hit me....as of now, a plain old base GT Mustang is quicker and faster than arguably the fastest production car of the muscle car era: the Shelby Cobra 427. A new car with 60% more weight and 30% less cubes is faster, even without the advantage of forced induction. That just amazes me.

I have a better question - has he ever floored the V6 even? Part throttle racing FTW.

Isn't it amazing how fast the S550 is compared to those old muscle cars? I mean I'm not being a fanboy here but as a fan of old muscle cars from a young age I am amazed at how quick these cars are. They also feel a lot quicker once you do suspension mods. This is why I wouldn't ever want a supercharger on the Coyote. It is more than fast enough for me. IMO the power I have now is right on the edge of being able to use the power it's capable of - within reason of course. 700hp-800hp is a little ridiculous to me, but I see why people like it. More fun factor.

Mine is whipplecharged and traction is non-existent at any speed under about 80....and that's on the wider PP1 rubber. It's just silly.

Yeah, that's what I mean. Lol. You know what I'm talking about. Especially I imagine with that twin screw type blower. Your Coyote with the twin screw... Jeez.

Here is the thing.

While there may be no definitive numbers affected and the exact block issues - there is enough evidence for me to hold off buying one until my concerns are addressed. The V6 runs like a champ with zero issues for the time being. Going back to an iron block is a gamble many of us would take over new processes that may not have been fleshed out yet.

The aluminum block has nothing to do with possible tolerance issues. I am also an engineer in the auto industry, and I have dealt with tolerance related issues. None of the processes Ford is using in the Coyote are actually that new. The few failures that have been documented on this forum are in areas that have no new tech (wrist pins, cam followers/journals, oil pump gears, etc). This new big block is unproven, while thousands of Coyote engines have made it beyond 100k miles. While some Coyotes have failed, the failures tend to be known and correctable. Basically, your cheapest options are to buy a built 5.0 from a well-known performance company, swap it in place of a factory 5.0, and run E85 (or add mods you want for low end), or just buy a Chevy with the engine you have more personal confidence in. IMO, I have seen issues with GM engines that we don't have with the Coyote, and it doesn't give me any warm fuzzy feelings over their quality.

I can imagine. I am guessing I am pushing close to 475whp on 285 wide RE71 tires, and traction is a very real issue. Even if I roll into the launch, then mash the gas, the tires are going up in smoke. If I have the tires hot, I can catch traction midways through 2nd.

With my 18 manifold and JLT (probably in the 500 crank area I am guessing) I can now go full throttle from a dig and keep power down all the way. With advancetrac off. A slight wiggle of the rear end as I shift into 2nd and then straight down the road. Break the tires loose again as I shift into 3rd gear at 7800 rpm. Real good fun! Also 285 tires but not RE71Rs

The LS7s have the guides and hollow valves stems. But this is easily correctable by the owner of not already done.

Are you talking about the ones that put a hot cal and bigger turbo on the existing 2.3? I'd say that was nothing by comparison....

I floored my V6 Mustang once so far this month and that will probably be it. I floored it twice last month cause one was a protest flooring to show I could still get it up! This is who you are dealing with.


The lack of torque is another thing. I’ll spend 8 hours a day driving trucks that have 3-5 times the torque of a third generation Coyote and I usually floor it twice a day for maybe 25 minutes each time.


So my preferences may be a bit different than yours.


The Coyote 3 will be a fab motor when all the bugs are worked out. And let’s be honest that there is a few issues though not all owners are affected.

Coyote plus a Whipple... there's your torque. Enough to melt your face off and the tires haha.

Learn to let go. Come into the new age. Leave the big pushrod motors behind. Learn to check your emotion from preconceived notions and listen to logic.

The new age happened for me in the Fox body era. Those cars were faster than the ones today...


How?


Because they were so much faster than the rest of the cars in the road. I could count the cars on the street that could beat me on one finger: The Current Corvette. That was it! How many cars today are faster than the Mustang GT? Answer: Lots!


Those cars sure didn’t feel slow at the time because everything else was slower. When you judge those times from the future you do those that lived then an injustice as we could not see into the further to know we has “slow” underpowered cars.


So when I argue with people who like to push out numbers - well - feelings matter too. The third generation Coyote didn’t exist in the 1980s so comparing it does not make sense. Compare the GT to a Tesla Performance Model 3. Massive, instant torque and it holds a gear. But don’t own one out of warranty...



But I like the torque down low for the experience!

If your argument against the Coyote equipped Mustang is that there are faster cars on the road than it, well... yeah lol. But that doesn't mean much because the advancement of technology has allowed more players into the game.

And if this really is your point, the 7.3L V8 will not do it for you. In fact, it will push you farther away from that goal. It will make the S550 slower. Buy a different car. Go buy the Tesla! Seriously, go buy it.

There was a brief period where the Mustang GT was quicker than the Camaro/Firebird. Once GM put the LT1 in the 4th gen f-body (1993), it took a while for Ford to catch up.

Do you understand that you don’t get the engine torque rating at part throttle? In other words, at constant speed or light acceleration a 3.7 and a 7.3 are producing the same amount of torque. Estimated 450 or 500 ftlb is only the available torque when you floor it.
