Lol. Safe to say that mustangs image is continuing to rapidly move back to a "man" car.

 

Most 2015 V6 Mustangs will be rentals.

 

The 'Secretary Special'

 

Yeah the Option list is VERY bare bones for the V6.

 

Saw this at the mfr. They got the HUGE contract to build the manifolds/headers. They call it manifold.

 

Its to bad they pigeon holed the V6 like they did, I'd take a sixxer over the EcoBoost provided you could get it in the premium package and whatever suspension goodness is available to the Ecoboost Mustang.

 

Ford really needs to change the "performance package." Most people who get it, whether it was in a 2010-2014 or 2015, will end up changing it anyways. Just make the fricken Perf Pack include a lowered suspension and they'd sell a LOT more Perf Packs.

 

I'd say that the Mustang is rapidly moving toward being a rich man's car, considering that a loaded GT will likely be very close to $50K. They may sell more V-6s than people think at that rate.

 

Ford seems to be phasing out NA motors. At least the 3.7l v6. It was replaced on the new f150 already for a more efficient 3.5l v6.

 

Ehhh they just put the 3.5 in there to give more breathing room for the 2.7TT and make it look better. If you compared the 3.7 and 2.7TT side by side, as today's 3.5TT and 5.0, they'd be very close in performance, even if they numbers don't tell the same story.

They also specifically detune the 5.0 in the F-150 to make the 3.5TT look better (of course they say to make more torque, but my car has NO problem with torque off the line lol).

 

Are you certain about that? It seems to me that the ideal tune for a near sports car is not necessarily the ideal tune for a work truck. It may very well be that F-150 drivers are happier with their 5.0 tuned the way it is than if it were a Mustang GT engine.

 

I think it's a combination of both, honestly. I'm sure you can't just plop a 420/390 engine in a truck and expect it to perform like you want a truck engine to perform, but the F-150 is rated 360/380 from Ford. You can't tell me they lost THAT much power by "tuning it to perform like a truck engine."

 

Actually, it's completely believable. The F-150 5.0 has a different intake manifold with longer runners, smaller lift and duration intake cams, 10.5:1 compression, and exhaust manifolds instead of the shorty headers on our GTs. Mix that with a conservative tune that has the torque band close to the bottom of the rpm spectrum and you have what's in an F-150.

I thought it was about marketing with the two truck engines, but everything I just said would account for the 60HP that was lost. The ecoboost is only rated at 5 more HP and 40 TQ, so it shouldn't sway people too much. I do believe the 5.0 F-150's torque is under rated though.

 

Again, in my opinion of course, I don't see how that is all necessary to make it more "truck worthy." I'm not disputing the engine has differences... Unless, they were purposely handicapping the F-150 5.0 to bolster EcoBoost sales. Take a look at local lots - the dealers hardly order 5.0 trucks and they get extra incentives to sell EcoBoost trucks...

 

Nice numbers on the ecoboost, will be funski.

Would love to see the EB hardware on a older v6.

 

They've also always cammed them different right? More for low/mid range torque vs high end hp. Same with the 4.6.

 

Yep, they did the same with the 4.6 too. We had the 4.6 in my dad's 98 F-150. Still, the power discrepancy between the 98 F-150 4.6, 98 Mustang GT and 98 Crown Vic was negligible. They also didn't have EcoBoost V6s to share showroom space with though

 

Let me try to illustrate this a bit better. The 5.0 in the Mustang makes less torque under 3,000rpm than the 5.0 in the F-150 does. I've seen it on a dyno, and both vehicles had a 6R80 with a 3.15 axle. The F-150 needs all its torque down low to for towing(obviously lol), as the 5.0 mustang engine doesn't produce good torque numbers for towing below 3,500rpm, which most people are driving their vehicles at.

Actually, I've constantly been thinking how much less low end torque my 5.0 has over my old Chevy LS engine the more I drive it. These 5.0s are the K20 of V8s, in the fact that they need to be spun high to make power.

I hope I'm not coming off as a know-it-all, but I've been building and machining V8 engines since I was 15. The differences between the two 5.0 engines are as clear as day to an engine builder. The parts mentioned would easily drop 60hp. I just don't see where the 10tq was lost. Perhaps in the camshaft timing, or maybe marketing on the 5.0>3.5TT feud.

Here's stock dyno numbers of a 5.0 F-150 to back up my claims. Stock coyote mustangs put down roughly 360hp/350tq. These are SAE corrected.

What is selling the EcoBoost F-150, IMHO, is the MPG lie that Ford is marketing. My fathers EB can't get better than 17mpg, yet it's rated at something like 22mpg.

 

Make sense. Also maybe easier since they already use a 3.5 in the TT application.

I don't know how much the f150 5.0 is detuned however. Internally, heads, manifolds, cams, etc. are all totally different from the mustang 5.0.

Personally I'm loving that 2.7TT. That's the motor I'll get on the f150 when my dd dies.

 

I'll add that I do get what you're saying Patrick, in the fact that why would they take a perfectly fine 5.0 coyote and detune it for a truck. I honestly think Ford could have designed a more efficient truck motor out of the 5.0 than they did, but I do understand some of the changes made where necessary to make this high revving V8 more truck oriented. In that aspect, I suppose they didn't want the V8 to have more power than their twin-turbo v6, so they could sell more.
