No more V8 in F150?

[Diamondpilot]

I wouldn't say any one is that much above the others. The numbers can change any day. It comes down to them all being at the mercy of suppliers, but they choose and monitor the quality of the suppliers so it still falls on the manufacturer. I'm just pleased to see them issue recalls and do the right thing by fixing problems as they are found.

Any manufacturer would be foolish to try to hide it after the Toyota mess.

I think they have all learned.

You do know that the 3.5 ecoboost block has 6 bolt mains and it supports the forged crankshaft with a girdle...right?

Was just thinking, is the Ecoboost OHV or DOHC ? four bolt mains, IMHO, only make sense on OHV V engines to add structural rigidity to the block, because OHV V engines have this hole in the bottom of the Vee to accomodate the camshaft. Ecoboost probably has a much stiffer block due to the absence of the camshaft bore in this key area.

 

[Sysop]

Four and six bolt main bearing caps are used to seat and support the crank in high stress situations. The higher loads the engine is built to be rated for, the more support the crank needs to remain true. Many SOHC/DOHC engines (V8 and V6) still have a "cam bore" through the block, but rather than a camshaft, it has what is called an intermediate jackshaft. This is basically a shaft that runs from a timing chain off the crank, then uses two more timing chains to drive cams in the heads. Generally the head on the driver's side is ran from the front, and the passenger's side head is ran off the back of the engine. This is how the 3.5L ecoboost is built.

The ecoboost has more main bearing surface area to support the crank than any of the gas V8s ever produced, which is pretty much the main reason the ecoboost is rated to take more load down the road than any of the V8s. To have the rigidity and support for these larger-than-typically-used-on-an-engine-of-this-size bearings, engineers decided on 6 bolt main caps. Longevity under load was their goal.

Aluminium blocks are also a factor that weighs in: I think its BMW that has an engine which head bolts are bolted all the way down to the crank bearing area, to save some meat in the area inbetween.

===edit: i think Ford is doing what BMW is doing for more than 10 years now:
Engine of the Month - Ford 2.7-Liter Twin Turbo EcoBoost V-6

On inline engines i have never seen more than two bolt mains... Thats also because there is more room to put larger diameter studs in the block, and still have enough meat to thread them into. If you look at, e.g. LS1 (??) engines, they have a cross hole to turn two lateral bolts into the bearing cap, to tie the bottom end together like one rigid part. I have never seen such thing on heavy duty industrial engines...

Well, well, looks like the 5.0 is coming back for 2018. Yeah, little V6 just doesn't cut it, for real truck work.

Coming back for 2018? It never left. Although most sales are for the V6 engines now, and some of the V6 versions are more powerful than the V8, but there are still many V8 sales to go around.

I'm waiting on the 2018 model order bank to open up and will go with the 3.5 this time, but only because i don't keep vehicles more then 4-5 years and am not overly concerned about the complexity of the ecoboost engines. Otherwise I'd go with the 5L again. I think Dearborn will start the 18's mid July. Kentucky a little later.

NEW ENGINE OPTIONS

Based on your need, the 2018 F-150 provides more engine alternatives all paired with a 10-speed transmission to deliver improved acceleration and performance.

- All-new standard 3.3L Ti-VCT V6 – 290 HP/265 lb.-ft./rpm
- 2.7L EcoBoost® - 325 HP/400 lb.-ft./rpm
- 5.0L Ti-VCT V8 - 385 HP/397 lb.-ft./rpm
- 3.5L EcoBoost - 375 HP/470 lb.-ft./rpm
- High-output 3.5L EcoBoost (on F-150 Raptor) - 450 HP/510 lb.-ft./rpm

Also look for yet another powerful new option… with a new 3.0L Power Stroke® Diesel engine. Coming in Spring 2018.

FYI, Dearborn (DTP) and Kansas City (KCAP) build the F150. The Super Duty is built in Kentucky (KTP).

Right, i goofed. I know the 150 is build at both Plants. I may be wrong, but since i ordered my 2012 Plat with a 6.5 foot box, which was build in Dearborn, all 6.5 foot models are now build at KCAP. Would you know if that's accurate?

This was an utterly clueless comment.

No, that's not true. I believe all 8' models are built at KCAP, and I'm thinking all Platinum and Raptor models are built at DTP. I'm not 100% certain though.

As are most of his comments on Ford vehicles. He has a hatred for them that he won't let be changed by facts that differ from his biased opinion.

I was referring to the 6.5 foot boxes.

 

[Ford850]

I was referring to the 6.5 foot boxes.

KC used to make all super crew's that had the 6 1/2' bed. At least that's what Ford told me when I ordered mine. I know they definitely made all the heavy payload f150's which were only available with the 6 1/2' bed. That was before the retooling for aluminum, and I don't know if that's all changed now.

Is it so important to have a light truck with a V8 engine? In Germany there is almost no market for such a vehicle. In spite of the VW diesel discussion we use diesel engines, 4 up to 6 cylinders. Excellent economy, durable and with much power in each situation. The other way: I hope for the Tesla Pick-up truck, full electric. With a farm and large roofs there is enough place for many solar panels for your own current flowing into the wallbox and the home own supercharger.

My supercab 6.5 was built in Dearborn in March 2017. Ford will keep providing the V8 as long as there is a significant demand but after getting the 3.5 ecoboost I don't see a need for a V8.

 

[fordmantpw]

I understand, I was just pointing out the only specifics based on bed size that I know of. The 6.5' boxes are built in both places. The 8' boxes are not.

As the fleet tests continue to prove the 3.5 ecoboost to be a longer lasting, harder working engine than the V8, the V8 demand will shrink significantly.

I understand, I was just pointing out the only specifics based on bed size that I know of. The 6.5' boxes are built in both places. The 8' boxes are not.

I think the difference for which line they get built on is more to do with the frame length/wheelbase than the bed sizes.

I agree. There is a replacement for displacement and it's called turbo psi.
