What's the point?

That's a massive assumption, but I like where your head's at.

I mean, obviously its a huge assumption, but, it was the only way to logically prove the point i was trying to make at that point in time.

So why not just ask for a scaled up ecoboost engine?

 

[Dirtman]

I dont know why they cant just stick 400 CI+ big blocks in everything. Screw the govt.

Just one mans opinion.

With that logic why not just use 2 stroke turbo & super charged deisel engines in everything...

Oh. You mean the old Detroit diesels.

Now you're talking.

Because that engine won't fit under the hood of a Fiesta? Or a Focus? Or an Escape?

I always thought that the smaller Ecoboost engines made the same power as the standard engine, but got better mileage. Consensus here seems to be that's not the case, though.

Cause, at the time i was in an argu....err, debate with some diesel freak. He was saying that there was no way a big block gasser could ever make the power of a diesel.

I said given direct injection and twin turbos like a modern diesel a big block gasser would be right there with them and used some far out modeling to prove my point.

It probably could but it wouldn't be a linear power increase like you probably figured.

Usually as things get bigger you do lose some, other things have to be scaled up more to come out the same and things get heavier at a ratio different than the original non-scaled version. And bigger heavier parts changes things.

I get that, but the smokey brain i was argueing with on FB didnt.

I think Cylinder De-activation at highway speeds can get the same results as EcoBoost on paper. V8 power when you need it, gas sipper on the highway. No extra heat from boosters, just a computer program and some minor extra hardware for balance and lubrication. I don't know why this tech was abandonded by the... oh wait yeah I do, MONEY$$$.

 

[fastpakr]

Cylinder deactivation has been tried in varying forms for decades. It's a lot more complicated than just flipping a switch to disable fuel and ignition to half the cylinders if you're going to do it right.

Talk to GM about the MDS on 08ish 5.3....

Blew so much oil into the intake you didnt need an air filter

Talk to IH about it with their V8 tractors.

They would kick down to 4cyl at random or just stick and only run on 4. Most of them had that mode disabled.

Both Dodge and GM use it now, it must not work too bad if people are still buying them.

It's definitely a lot better now than it used to be. I'm not against it at all, but it's not a simple system or really an alternative to direct injection and boost. Just another piece to the puzzle of continuous improvements to fuel economy and emissions.

It kind of is an answer to ecoboost, they get pretty respectable mileage and still have the power of a V8.

I know guys that have them and they don't have anything bad to say about them.
