As manufacturers are constantly trying to make their engines better and better, I was wondering what Ford's next move will be with the V10. 2005 sure saw alot of improvements to the Super Duty, especially going to the 3 valve setup. Would you think a variable cam would be their logical next step, like they did with the 5.4 V8? I would be interested in what many of you V10 enthusiasts would foresee as changes that might be in the works for the V10 and/or what you would like to see done with this engine. As much as this engine is appreciated by its following, the answer might be to "just leave it alone."
I think fuel efficiency is gonna have to be one of the issues. With the emissions and economy requirements getting tighter, that may be one of the things we see.
Variable Displacement so I don't have to do it myself.
For those following my Variable Displacement adventures: I have been able to get into the "fail-safe cooling" cycle without the engine being "overheated". It alternately fires odd then even cylinders -power feels like when I disconnected right side Fuel Injectors. Ford says I can run 50 miles at 50 MPH without coolant. I ought to able to run all day with coolant - ha,ha!
Adapt WHAT 4V heads...Are you suggesting adapting 4V heads from a V8 onto a V10??
Ford Does offer a 5.4 with 4V heads currently, however!
Well the 5.4 and 6.8 are known as the modular engines because they share so many parts. There used to be a 4v version of the 5.4 for lincoln and some of the cobras, but as far as i know they aren't making it anymore. Ford had this proven technology available and spent millions on developing 3v heads.. huh
A v10 with the 4v would be pretty impressive if you ask me. Maybe they were afraid the v10 would outperform the diesel?
Richard 2212 - What did you do to get into the limp-home mode, and how did you know when you were in it? The real question of course is whether you can operate for extended periods and obtain improved mileage. Good luck!
4v engines only advantage[over 3v], is hp at high rpm's (at a high parts cost). 3v engines give most of the fuel efficiency's of multi-valve heads, at a lower rpm, maximizing both hp & torque. Remember, this is a truck application.
The 4v heads were used in the Navigator i believe. They were also DOHC and made close to 400 hp n/a and the same torque unless i'm thinking of the wrong engines.
