Why hasn't anyone released a HD truck with a Turbo V8?

But Ford owns Cummings......

I was talking more about the mindset of the people thinking that a smaller turbocharged straight six could not compete with a larger N/A V8 rather than what engines Ford currently has.

The big blocks up to the 90's didn't do that much. Oh yeah, you want diesel like performance, and mileage. Not gonna happen. You want gas? The current crop of V8's no matter which brand you choose will do a fine job towing within their specs. Yes, you'll be in the high RPM ranges, but that's the nature of the beast. They're made for it. The gap between gas and diesel won't be closed. Nowadays, you have to choose.

That is what they said about the half ton towing engines......until the 3.5L Ecoboost came out.

Although I didn't want just an old engine. As I said, I wanted something like the old iron block 300(4.9L) that was well known for its reliablity brought up to snuff with modern technology like variable valve timing, variable ignition, 4 valves per cylinder, direct injection, and turbocharged with modern turbos. Something like that could easily make 380 hp and 500 lb-ft at a much more usable 2,500 rpm. Not only that, but it wouldn't suffer the altitude power loss like the current N/A gasser V8s do

Point taken shiner, but I think (and this only a guess), that the only thing close to that we will see is a slightly bigger V6 EcoBoost for the Superduty. My reasoning for that is; the current 3.5 EcoBoost matches, or beats the 6.2 for power but I think it's a psychological thing that the SD should have a bigger one. So, when Ford feels like the EcoBoost has gained enough confidence from the public, they'll develop (or are now deleloping) a slightly bigger one, which should easily hit the 500 lb ft mark you mentioned, but in a V6, not a V8. As I say, this is just speculation on my part, so we'll see.

This kind of reminds me of when the 5.9L Cummins Turbo Diesel first came out in 1989. At the time, Ford had the N/A V8 7.3L diesel and every Ford owner back then talked about the unreliability of turbos, how a V8 is needed over a straight six, and how it was too small to compete with the 7.3L. It didn't take long to shut them up and for Ford to add turbos in 1993 and direct injection in 1994 giving birth to the Powerstroke moniker.

COST - WEIGHT - DEMAND

The claim is that V6 turbo's are cheaper to manufacture than V8's and they reduce weight by over 100lbs.

Also, demand has been mentioned in things I've read. Most looking beyond 400hp and double that in torque for consistent towing miles over many years, people will go diesel every time. And the occasional towers are not only reluctant but assuming the cost would be darn near equal, diesel wins again.

Also keep in mind that before the Ecoboost and the latest Gen turbo designs with direct injection fuel systems, towing and gas turbos were oil and water...they could not be mixed.

Those engines were some real turds and I doubt that the head gaskets would live a long life with those power levels.

Funny being that they were regarded by many to be one of the most reliable engines of all time.

How many did you have issues with that were personally your own? Did you ever blow head gaskets?

My dad ran the office of a local natural gas company (Entex)and he would track the cost of repairs on each truck and back in those days the service men could choose which brand of truck they drove which promoted them to care for their truck as well. Two of the Fords with this I6 either had cracked heads or head gasket failures and oil consumption was another problem. These trucks were always overloaded, idled for hours a day but were serviced on a proper PM schedule.

An even bigger turd was the slant six... Ask me how I know!

So we are not to believe the thousands upon thousands of people saying that this engine is one of the most reliable engines of all time (including me who owned four of them in various equipment and trucks) and instead believe you, a person who is known in this forum to extremely exaggerate problems of another straight six engine that you also have a disdain for..... hmmm, I think I am going to take my chances in believing the thousands upon thousands of people along with my own experiences with the engine.

Let me guess, next you are going to associate head gasket failures with all straight six engines because something tells me that is probably where this is headed.
