2015 Coyote "upgrades" really all that and the bag of potato chips?

Finally gandered over to look at the 2015 5.0 specs, was not super interested in it because still no direct port and not really much of a power bump but it really seems like its a bunch of small changes that don't do very much.


  • Larger intake valves
  • Larger exhaust valves
  • Revised intake camshafts
  • Revised exhaust camshafts
  • Stiffer valve springs ensure valves close completely at high rpm
  • New cylinder head casting – revised ports provide straighter path to the valves for less restrictive intake and exhaust flow; combustion chamber modifications accommodate larger valves
  • Sinter forged connecting rods are lighter and more durable for high-rpm operation
  • Redesigned piston tops – deeper cutouts clear the new larger valves
  • Rebalanced forged crankshaft to support higher-rpm operation
These upgrades have boosted output of the V8 to 435 horsepower and 400 lb.-ft. of torque.


I really don't see much here other than window dressing. The current heads/cams support way more power than is needed and the "sinter forged rods" are just Boss rods and not a true forged piece. Pistons and crank... the current stuff supports a pretty high redline not to mention without the Boss intake you aren't going to support the higher RPMs anyway.

IMHO, no direct port=fail.

I would guess that once the 6th gen Camaro comes out, they will tweak this engine a bit more.

I think with the larger valves, revised cams and stiffer springs that they are going to be using those on a higher-rpm NA engine and this will just help keep costs down once that variation comes out. I would guess it's their way of future proofing.

Ford honestly needs to dump the 5.0L and punch this bish out to a larger displacement.

I doubt Ford will ever go Larger than the 5.0 for the GT.

Yeah this almost seems like a holding pattern IMO. A NA version of the 5.8 in the Shelby would be ideal. Maybe that is on the horizon but they're only going to be able to go so far on 302 cubic inches. Proof is that with a simple cam swap the Camaro guys are putting down STUPID power numbers with the LS3. No replacement for displacement and I never thought I would say this but I will be looking at whatever iteration of the SS Camaro is out when I eventually look at possibly getting a new sports car.

Yeah, I'm not getting another Mustang, at least with this generation, unless it's a Special edition or SVT. Probably will just save up and get a new Gen SS 1LE, or a Corvette Stingray.

With the New Camaro getting the LT1, and probably being lighter ( I doubt they make the same mistake as Ford) and the Challenger losing weight in the next redesign, Ford needs to step up. And DI won't be enough by itself. Up the displacement.

Honestly, if I get a newer stang its almost 100% going to be a 2011/2012 A6. I love the earlier pissed off looking frontends on the Coyotes (vs the 13/14 smiling at you) and the overall styling of the S197.

If i do get another Mustang, I agree, it's going to be an 11-12, and I'll do a 13-14 taillight swap.

I find that most ppl I talk to prefer the 11/12 fronts and the 13/14 lights. Luckily the 13/14 lights are PnP and not too expensive and takes all of a few minutes.

I like the 13-14 front, because the headlights seem to wrapped around on the 11-12, but the lower front is bad, 11-12 looks better there.

2015 Coyote "upgrades" really all that and the bag of potato chips?

I know I'm in the minority on site but I love pretty much everything about the new S550.

Took a size able hit on my '13 5.0 and traded it in on a '14 Focus while I wait on the '15 to get here I have ordered. Focus will be daily driver.

I loved my '13 and miss her dearly, especially after I spent $1500 on the Roush front end and got rid of her less than a year later. Driving around in this rocket ship aka Focus is making me sick when I see a nice mustang.

I get that not everyone likes the S550 but I think once more hit the street and the aftermarket catches up ppl may change their tune....may.

I've been banging around Mustang6g.com and who knows. Everything about it seems drastically improved except the motor. Lucky for me, I'll be able to see the 2015s,16s and probably 17s come out before I'm rdy to buy. If last model was any indication, the 17s will be a mid-model run refresh. Cost is also an issue, these damn things are being pre-ordered for $40k.

I'm still not sold at all on this being a better straight line car which is what a lot of ppl are going to be caring more about.

I'd like to see it hit a track. It should handle very well. And it being more capable of high rpms now should help very much at the track.

Its good to be in the minority and fortunately for you, you were and are in a good financial position. This allows you the availability of being able to take a sizable hit on your one year old 5.0.

God bless those who can spend 1,500 dollars on a appearance mod (Roush front end) and then turn around in less than 1 year and get rid of said car. Your the man bro!

Ha thx but hardly the man, I wouldn't be doing this if I'd ordered my '13 and got more options. And I hate to say it but I hope they wait a few years on a glass roof for the S550 because I will probably grab one of those and call it good....for then at least.

Thx for the nice words though, if anyone is interested here is my '13 for sale. PM me I know what they have into it

True I admit I look at 1/4 mile times and have always used those to judge how fast a car really was. Then I finally realized the most HP doesn't always mean the fastest times and gave up seeking that.

I'm looking forward to the added technology on the S550 more than the HP/TQ bump (but yeah seriously 450 would've been cool). I was happy enough with the power in my '13 so the extra 15/10 will be nice when I need it.

I do actually intend to take this one around a track which is why I'm paying to lose heated/cooled seats and go with Recaros. But certainly don't want to fall on my face at the strip so we shall see.

When I had to decide between the 12 &13 the front end is what sold me- and $500 savings helped, not that it was a deal maker.

I love the 12 Roush (and GT) front end, with the 13/14 tail lights. Even the rear bumper on the 13/14 doesn't look great to me. The only thing I don't like about it is the ABS side skirting, vs the body colored on the 13/14.
