No Replacement For Displacement?

[Dirtman]

Meh... I haven't seen any Godzillas around to judge them. Are they even in any of the new trucks yet?

I kinda understand the niche they are suppose to fill, people who want an HD truck without paying the premium for a diesel. But still... meh...

19+ I think. Its been a slow trickle getting them out lately for some reason.

I want something with more bottom end than a Coyote. They are fine on the highway with great passing power but putting around town like I normally do it feels like there is nothing there unless I really put the spurs to it. My dad's '05 F-150 with a 2v 4.6 feels like it has more onions off idle and I consider that a pretty low bar.

Then I don't really like the ergonomics of the cab and the steering is way too light.

Not a huge mopar fan but I am tempted by the 5.7...

I'll never understand that diesel gasoline thing, its pretty clear lines there
You want pulling power torque you use a diesel(or electric like a train)
You want quick torque you use gasoline(or electric)

You want both then get a diesel/electric hybrid, like a train, lol

I understood why people wanted diesels when, diesel was cheaper, diesel's got 20% or more better fuel economy and they lasted far longer...

But currently, diesel (including DEF) is 20% more; they don't get better fuel economy and don't seem to be lasting any better, I can't see why you would pay the increased initial price...

Because RACETRUCK!

I've towed the same 30 foot trailer with a 6.7 diesel and a 6.2 gas, at the time both being Fords biggest pickup engines.

Towing that trailer there was no question whatsoever why you'd want a diesel... Gas engine got to stay home next time the big trailer came out. The Godzilla would need alot to impress me to use it over a diesel for towing.

Diesel fuel has more energy per gallon so will always get better MPG
Diesel engines are also more efficient that gasoline engines in converting fuel to motion
Gasoline was about 25% and getting close to 30% now
Diesel was 35% and getting close to 40%

Diesels run higher compression, compression is like winding up a rubber band and releasing it, the tighter you wind it up(higher compression) the more energy will be released

Diesel engines cost more to build because of the higher compression and power released

Anyone remember in the 80's when Chevy tried to turn a small block gas engine into a diesel without doing ANYTHING to strengthen the block?

Oh Chevy... You so silly...

Can you imagine how many diesel mechanics stood outside the engineering department doors whispering "hey Bob come listen to what these idiots are planning!" And when they finally finished building it a universal statement of "wait for it...."

 

[fastpakr]

The Oldsmobile engines? Yeah, those were a mess.

 

[85_Ranger4x4]

Newer diesels do get about the same mileage as a gasser now. They have all the regen crap plus they make A LOT more power.

I have 0 interest in a diesel anything. Bonus points for a more compact pushrod engine.

I just like the sudden burst of torque taking off from a stop sign so I feel like I actually have something.

 

[85_Ranger4x4]

Not sure how related they are but they had diesel 350's in trucks too. I think they morphed into the 6.2/6.5.

@Dirtman:
I'm talking F-150, Rangers and down. The 3.0 Ecodiesel doesn't compare well to 3.5 EcoBoost

Yes, Neighbour's grandfather had the original 5.7 Olds with the 350 diesel in it. Got good mileage, but was it ever a slug. The 6.2 was a separate engine from Detroit Diesel - it just needed compression lowered and turbo...

We also had a tandem with a 702 Chev V-12.

For keeping up with the combines in harvest, it trashed the tandem with the 855 Cummins. It would just rev so much faster, especially empty that you could get 5 loads in to 4. When there were thunder clouds on horizon, keeping the combines running meant more than couple gallons of fuel.​

@snoranger:
The engineer in me abhors over fueling a diesel to the point it "rolls coal". And the Ranger on the calendar page for this month is more my interpretation of Race Truck.

"Tweaking diesels" is what got me sent off farm to university...

@RonD:

The F1 gasoline engines are exceeding 50% efficiency

Diesels don't get more MPG if the emissions controls reduce the efficiency thorough need to control NOx and soot to point where they are worse than that of gasoline ones.

@85_Ranger4x4 :

Get a truck with 3.73s, not 3.31s and put transmission in Sport mode. The nanny's that want good fuel economy numbers have neutered the truck from push you back in seat acceleration in stock setting.

So long as everyone is looking at hp numbers, pushrod engines will be rare - they just can't rev enough. 3.slo in my Ranger just can't compare with 3.0 Duratec in my daughter's Escape.

 

[RonD]

The F1 engines get 4MPG, so not sure they are "efficient" in the same way I was thinking, lol
But yes thermally they are almost double the efficiency of regular gas engines

Assuming 25% and 35%
If gasoline was $4 a gallon then $3 goes to heat up the air and $1 goes to pushing vehicle down the road
If diesel was $4 a gallon then $2.60 goes to heat up the air and $1.40 to pushing vehicle down the road

3.55's... which unless I order a new one is about as good as it gets.

In domestic truckland only Ford has OHC V8's and even they are showing interest in bringing back pushrod engines. Godzilla in SD's and there is talk about scaling down the 'zilla for the Raptor.

Pushrod engines can wind up, some just are not tuned to.
