More V6 vs. EcoBoost Banter, Please

[Jamo]

It's been a few weeks. The '12 GT that I was going to buy got sold to someone else while I was looking at it for the third time. Once it sold to someone else I became sure I would have settled on it.

But now I'm decided to go with a V6 or eBoost anyway.

...

I got a call from the above referenced saleswoman at the dealership. Their deal on the '11 GT P fell through. Financing. It's now down to $23.5K It's really a nice car w/everything (but Nav or glass roof). If I wasn't such an idiot I'd be over there now. But now I'm more interested in the '15 V6 or eB. And I still should sell a motorcycle first.

Honestly I could never get an S197 after having spent time in an S550, regardless of how good a deal it is. The engine is fun, but the handling isn't, nor is the interior even in premium spec.

I agree with that! I was in the market for a Muscle/Performance car this year and was thinking of going with either a pre owned Camaro SS or Mustang GT. Thank God i saw the new 2015 Mustang in person driving by the local dealer. It was love at first sight. The interior is light years a head and with the new tech and IRS it was a no brainer.. So if i didnt see the 2015 in person i and saw the huge growing aftermarket for the new i4 Turbo i actually would have ended up with most likely one of the previous gen Camaro or Mustang v8's.. Once i researched the new Mustang options and models i chose the EcoBoost based on the Tuning capabilities for serious power and 32 mpg.. But the s550 is light years ahead.. Interesting to see what the new 16 Camaro will be as well?

It's just the nature of the configuration and the physics. The misfire issues from the 2011 F-150 will have largely been taken care of via calibration and active grille shutters (don't get rid of these when you swap ICs!!).

What's your theory on the AGS and carbon buildup? I don't understand how these affect it.

All I know from my research is that when closed @ highway speeds, they push the air around the car, which is less resistance... Lowering the drag, thus better MPG.

Also, not having them means better airflow into your IC.

Separate things entirely. I was referring to misfires. The calibration as it was, intercooler efficiency and certain weather conditions caused condensate to form in the IC. That caused misfires.

The 2015 F-150 uses its lower grille shutters on the two EB engines to control IC temps in addition to fuel economy. When closed or partially closed, less charge air cooling.

The carbon build up is from the direct injection. No fuel flow over the back of the valves, so vapors will gather in the ports and coke onto the valves from the heat (port fuel injection also cools the valves). Modern gasoline has quite a lot of detergents that act as a solvent for this on PFI engines.

Gotcha, thanks... I have read about the condensation issues on the F150. One of the vendors chimed in on the EB forum on this (can't find the post). So far, no condensation issues. (I live in FL) where humidity/dew point would be perfect for this. Either way, I'm keeping a close eye on it with the aftermarket IC.

I wish there was a way to look at charge temps in the built-in gauges menu. Only IATs

PS: Already have a catch can installed

It's a very different vehicle profile. The IC on the F-150 is sized to be competitive for towing. That means very, very long periods of WOT or high load in high temperatures. The Mustang, as high performance as it is, doesn't have anywhere near as severe duty profile. That said, I'm sure part of the reason the Mustang's IC performs as it does is because of the issues with the 2011 F-150. The grille shutters are a huge benefit and just keep it in mind when you go pick an aftermarket IC. The ones that keep the shutters functional are the ones that will keep your car performing on the track and as a DD.

People have been upgrading the intercoolers on the FoST, FiST, and Fusion cars, along with removing the AGS, without problems. I really think that condensation will be a moot point with these cars too.

I'm still tempted to option out a V6 just because you can get the 3.55 ratio without adding all the weight of the performance package like you have to do with the eB.

From what I can determine from reading The Weight Thread, the weight of the PP brakes alone is over 100 lbs more than the regular.

All in what YOU want.. If you plan on moding your car the Performance Package already has your Suspension upgraded and comes with a K Brace, Bigger built rear sway bar, a tuned chassis, larger break rotors and 4 piston brakes,nice 19" wheels with Performance tires,Tuned stability control,aluminum dash panel,you get 3.55 gears,Larger Radiator for better cooling,heavy duty front springs,Gauge pack and rear spoiler delete.. If you dont plan on modding or want to buy all aftermarket parts down the road then none of that stuff matters and just get what you want.. I dont know if it really adds 100lbs or not.. But your getting alot for the money and its already done from the factory and it all matters if you care about performance.. If you dont then dont worry about it,..

That's what I'll be getting.

That said, I don't think the EB PP brakes weigh quite that much more. It just gets the base GT brakes, not the big Brembos. It gets a larger radiator, larger wheels and larger brakes, in addition to the stiffer springs and roll bars.

You'll be getting the (manual) V6 with the axle ratio, and damn the naysayers?

Yes sir. I got to test drive it and really enjoyed it but a quick test drive isn't much, especially when it's not fully broken in and the adaptive learn isn't complete. I got a manual rental with 3.15s and had a blast for the 4 days I had it (had about 4000 miles on it). I knew then the 3.55 would just be icing on the cake.

I believe Bay1Stang has the same configuration.

I'd be the happiest guy in the world if I could get the same Perf Pack as the EB on the V6.

I have auto. I actually haven't driven v6 in 3.15 so I can't comment on it, but the 3.55 is awesome. You need to be gentle in first gear because she's ready to go. 2k+ rpm and the car pushes you into the seats even without that much throttle. : )

When I test drove a 3.55 auto I easily got the tail out (very controlled) in 2nd gear entering a freeway ramp. It scoots.
