I'm just here to argue about 4A vs. 4H again.

Two issues - #1, Ford only needs to attract the kind of people that buy brand new cars. They don't care a single bit about used car buyers. The closest they get to caring about used car pricing is maintaining value over the first three years so they can charge higher lease rates. #2, you're...

Is this conjecture or do you have marketing data to share?

For every single component in a vehicle, a design life is chosen - years, miles, rotations, power cycles. The component and manufacturing process are designed so that 99.999% of components make it to that lifespan. This isn't done accidentally, haphazardly, or by any amount of chance. They do...

Of all of the horrific Scotty Kilmer-esque YouTube car personalities, FTM is not one of them. I disregard nearly everything I see from car guys on YouTube but I fully trust FTM - his videos and diagnoses are spot on and he's saved me hours of time and thousands of dollars. A couple things to...

But what do you think that means, technically? In no possible situation can the ECU take advantage of any higher knock resistance? In no other elevation or ambient temperature or engine load can the ECU use any higher octane than 93?

What do you mean that it's "designed for 93"?

[citation needed] I've never seen a reputable source claim 91/93 octane E0 has lower energy density than 87 octane E0. Octane is the resistance to ignition - it's less likely to spontaneously ignite. Once ignition is initiated, the characteristics are basically the same. 15%

The 2.7 EcoBoost, 3.5 EcoBoost, and 3.7 NA all share a bellhousing pattern. I have a V6 Mustang MT-82 bolted up to a 2.7 EcoBoost right now. It just required moving a bellhousing dowel, and then using the Mustang block plate, starter, flywheel, and pilot bearing. All bolt-on, no fabrication...

^^^^^^^^^^^ The first honest car dealer ever.

What year? It's swappable. Transfer case, TCCM, and 4x4 knob, plus a little Forscan and baby you got a 4A stew going. I swapped my 2011 Lariat since they didn't do the ToD until 2012, but later XL/XLT modules can be swapped.

Jeep had Quadra-Trac in 1973 and Selec-Trac in 1983...4-Auto is very old technology. ....and people have been flying into the ditch for decades. The question is not, "Can you survive without it," (duh, obviously). The question is, "Are there measurable benefits?" (duh, obviously).

I think you're low.

Totally, I was agreeing with you. On my wife's 2.7EB MKX, I'm spending about $470/yr on upkeep, but I get tires for cheap, I do my own work, and this year I'll have to do brakes which will really throw off my numbers. It would be SIGNIFICANTLY more cost if I was having the dealership do it.

^^^ They're never going to assume you're doing the work yourself, as that would be an asinine assumption for a website to make. Going straight from the owner's manual's recommendations: Synthetic changes at your Ford dealership every 5,000 miles are probably $75 with coupon, and that includes...

For big, reliable, cheap power it's really the only answer.

High flow pump? Not with dual injection. Stock fuel system supports plenty of power, and if you need more just throw in some bigger port injectors. Stage 4 turbos are $2450. Completely stock fuel system: Does the 4 grand include fuel system and turbo? You included those above. The EFR 8374...

Please please please share your dyno plots. Here's a 2.3 making 400hp, spools by 3000rpm. Here's one making 500hp, it's not spooled until 4500rpm: You have a 600hp 2.3 that hits torque peak by 2500rpm?? I don't think physics supports that, but I'm open to seeing a dyno plot. 600hp at 7000rpm...

This isn't the conversation I was having - we were talking about all-out max HP builds, not stock powerbands. But I'll play along. Comparing torque peak RPMs without referencing actual torque output is kind of ridiculous. "The 2.3 hits torque peak at 2500 rpms where as the 2.7 hits torque peak...
