I know there has already been some talk on this engine, but I've been thinking about it's potential and ability to work hard with a turbo.

I think Ford's new (in 2010) 4.2 liter V6 (Turbo ?) is supposed to put out around 340 hp or so and 370 ft. lbs. of torque or so...but get's better mileage than the V8's. This will be a very interesting development.

I don't know if Ford also plans to put displacement on demand for thie 4.2 V6...but that would be great.

3 cylinders when puttering around...6 turbo'd cylinders for blowing the doors off chevies.

I'm still wondering if the turbo'd V6 would be able to keep cool and unstressed.. under load ....running hard and long at the high rpm end say towing a heavy trailer in the Rockies ?

I don't know if Ford has designed it for this, but I understand it's supposed to be an alternative to a healthy V8...so I think some will use it this way, just as they would a non aspirated V8. I wonder if a highly stressed (turbo) engine can handle this kind of loading....day after day with reliability and durability ?

Personally, I think it can...truck engineers I would imagine would design it for this kind of hard work.

Also, what are your thoughts on this engine....is this the future....why...if not...why not ?

 

It's got the same numbers as a V8 but I'm like you, I would like to see what it would do pulling a heavy trailer on a long trip!

 

i believe this is the ecoboost system... not looking forward to it really, can you imagine how strong the internals will have to be to put up with enough boost to produce that much power??? I say, GO DIESEL!!!!

 

Ya Sherm that is the ecoboost system. I think it would work good in car's and crossover's but not in trucks. Well maybe in trucks that don't get worked!

 

So far I don`t know much about it, sounds ok so far though if the fuel economy will be up there..

 

i agree. it could be a good base for a new SVT lightning or something. I'd take that engine in a truck that i could keep pretty for sunday driving and highway trips... I think it'll be awesome for that!!

 

I dont think the 4.2 is the greatest motor in the world there just trying to push too much power through them... stuff blows up the technology isnt quite there IMO.

 

i wouldn't imagine they'll use the basic 4.2 like is in your truck Ryan... at least i hope not. i'd imagine they'll be building a better base than that, but who knows??

 

I was just assuming based on same displacement but mI to would hope not. With my truck empty it is a reasonable motor for a runabout but as any kind of hauler it is not a impressive unit.

 

What`s your truck like on fuel Ryan?

 

I have got between 26-28 driving it easy unloaded.when you push it though it plumits.

 

Awesome, as good or better than our Rangers.

 

That is real good mileage!

 

one of the previous techs at Royal Ford had a '00 regular cab/short box, 2wd, 4.2L, 5sp standard and he claimed 30mpg on the highway...

 

I believe I read somewhere that it was supposed to be a 3.5 liter ecoboost was it not?

Would be great for light duty applications, but Im not so sure about heavier use either.

I bet a 4.6 v8 in a reg cab shortbox, with a manual, and tall grears would get damn near, if not more, then a 4.3 v6.

Ive heard guys with crown vics, and those lincoln mark VIII's (with the 4.6l) claim around and over the 30mpg mark.
