Mr. D

I'm considering buying a used 5.0L Coyote Mustang with an automatic. I can afford to buy a 2014,but I would mind buying used because I'm going to put a Roush Supercharger on it.

Here's the question:

Are there any improvements in the 5.0L Coyote engine or the automatic transmission that make it worth buying one particular year Mustang over another?

I understand the 5.0L Coyote first appeared in the 2011 model. It went to a 3 bolt water pump along the way, which doesn't seem much worth noting, but are their any changes in the yearly models from 2011 to 2014 that would make you buy one year over another? Of course low mileage tends to push me to later models....but then I have a 2008 with only 10K miles... so who knows!

i know in 2011-2012 they were 412hp and 2013 to 14 they are 420hp. i don't remember off the top of my head what the specifics are

I'm not sure those numbers are anything but marketing. My 2011 (stock) put down 389 to the wheels.. same day a few 13's were putting down 370s. Out of the 2011-13's that ran that day, I put down the best numbers.. despite everyone having CAI+Tunes and mine was stock. There is probably more variability in these cars than people realize. If there is a HP difference, it would be due to tuning from the factory, not hardware.

As far as improvements.. it is really hard to tell. The auto trans is said to be rock solid.. so I wouldnt worry too much about that. There is a difference in oil management beginning in '13.. but that also remains a big mystery.

If you are looking auto, I don't think you can really go wrong as long as you find a low milage car that hasn't been beat on or modified... which is always the trick

My 11 isnt babied and still feels new after 45,000 miles.

They did away with the oil squirters on the later models, not sure what year that changed. They must have had a good reason to abandon that.

Oil Squirters went away with the introduction of the Boss 302 Roadrunner engine and a new treatment for the cylinder lining. The gains were supposedly for only 12HP but that's likely more to do with tuning. Either way the Coyote's don't have the forged pistons like the Roadrunners. And those pistons lend more towards forced induction Mr. D.

On the other hand a 5.0 stock is already putting down more power and torque and doing it more efficiently than a 2010 ROUSH 427r.

Such a shame what a simple advancement in engineering a DOHC small block with some input from Jaguar will do...


Just saying....

that's not a ringing endorsement since Jaguar makes expensive, unreliable junk. They were absolutely garbage up until the '90s when Ford bought them, but after being sold off they've followed Land Rover in taking the attitude that "as long as we cultivate our image as a status symbol, our customers won't care that our cars and SUVs are pieces of ****."

Funny... Jaguar's engines are still. Assembled in the Ford factories in England. And jaguar is currently manufacturing a critically acclaimed Spanky cool sports car equipped with the 500+ HP flat plane 5.0 liter v8 that is manufactured in that same Ford plant. Sound familiar? Makes you wonder who gained more from whom? You take the good with the bad and learn from it. It would be naive to think Ford has not benefitted from Jaguar. It would be even more naive to believe the two companies still don't play in the same sandbox and share their toys like good kids that get along. like Ford has a reputation any better than what you described? Seriously... Get over yourself.

the Jag AJ V8 does not use a flat-plane crankshaft, why do you keep claiming it does?

Cruzinaround

A recent Top Gear Episode reviewed the 2014 F-Type coupe and described the optional 5.0 liter 8 cylinder supercharged engine package....as a flat 8. The Convertible tops at 495HP and the Coupe tops out at 550HP. If it was error on their part...maybe...but I don't think they make those kinds of slip ups on a show dedicated to reviewing the hottest cars. Facts checking straight on their parts...then in their words..its a flat 8.

Either they're wrong or you misunderstood. The Jaguar AJ-V8 does not have a flat plane crankshaft in any road-going application. besides, Top Gear is entertainment, not an authority.
