how mutch power could a v-10 hold safely on continuos bases. Tried looking up specs but with no luck

 

Do you mean continuous power like an airplane or generator engine that's running at a high power level all the time, or do you mean how much horsepower can you upgrade your engine to and still expect it to be reliable?

A similar horsepower aircraft engine would be rated for running up to 85% power performance cruise (in naturally aspirated form), but 55-75% being recommend. 55-65% for a turbocharged engine making similar power. It would be rated for a life of 1500-2000 hours like this, and if flown this way you'd probably expect to see a slight drop in power over time.

So, figure approximately 230 hp (75%) at an appropriate RPM to be running slightly less than atmospheric manifold pressure. It won't last a million miles, but it might last 1000 hours.

For the second interpretation of your question, I wouldn't suggest doing anything more than a chip and headers/exhaust if you want to keep it reliable as a street vehicle. History has shown a pretty strong correlation between increasing horsepower beyond factory specs and decreasing reliability.

 

talking about 100more torque 90 more hp. I want it to be reliable to tow and be daily driver

 

strock its pretty darn reliable to tow. Read some of the posts here about guys towing big trailers for a lot of miles with it. I have some experinece, with a 6500 or so pound trailer, it tows great. Then I drive it empty to work every day. Mine has 114K on it.

 

I tow real heavy with mine. My truck sees 10to15k on regular basis. I am putting a squires turbo system. Want to run 5 to 6 lbs when not towing and about 2-3 lbs when towing heavy. Just want to make sure that the engine stays together when the stress of towing comes into play

 

Don know how much power a v-10 can hold safely on continous basis, but the owner's manual specifies that if you use it as a stationary power source, it voids the warranty...

 

If you want to keep it reliable for towing (or reliable in general) the answer is simple: leave it stock. Adding a turbo system while towing is going to break something, especially for the heavy towing you do.

If the thing doesn't have enough zip for you, especially given your towing requirements, put some different gears in it. That will keep things a lot more reliable than boosting it.

 

I hear al of the things ypu guys are saying, but you guys are talking as if the v-10 is not durable enough to make 425hp reliably which is something that I think it can handle. The 5.4 is basicaly the same as a v10 and I know there are guys out there making 400+ with there trucks. All this experience in the forum and this is all the info you guys can give me

 

What year truck are you wanting to do this too?

 

Could it be that with all this experience, most of the V-10 owners on this site have found the stock motor up to the task that it has been asked to perform? It is not a diesel, where added power in large quanities come cheap and easy. It is a gas motor that has some very respectable HP and TQ as is in stock form.
There is a reason that the aftermarket is not flooded with add on parts, wonder products, superchargers, and turbos......in stock form it is producing pretty darn near its full potential. If you need more off the line or hill climbing grunt, that can be accomplished with the correct rear end ratio. Take a look at all of the motorhomes on the market, both Class C and Class A. These weigh 10,000 pounds and up empty. Add in the weight that a family stores on board for an extended trip and it can/will far surpass the weights you are taking about. My 31' Jayco Class C will run 80 MPH+ loaded all day long.
Don't expect Ford to honor your warranty in any fashion or form if you take it in with an aftermarket turbo installed.
Also make sure you check your states emissions laws before adding a turbo, such as in Texas it is against the law to add a turbo or supercharger to a gas powered vehicle after purchase from the manufacture.
Better yet, purchase your V-10 Superduty and do the performance mods you have mentioned. Then you can share your experience with us, I am sure most of us would be very interested in learning the limits and/or potential of the drivetrain of our trucks on your dime.

 

Well said, jonrjen.

I doubt that the guys with the 5.4s pushing 400+ HP are towing 10,000 lb RVs with it. Even if they were, reliability is going to be an issue.

Most of the folks here in this forum use their V-10s to do the heavy pulling. They are on a budget and can't afford to grenade their motor while pulling their RV on a long haul. I'm sorry, but you probably won't get what you're looking for here. Keep checking back though, somebody might help.

 

Don't let these guys scare you. If the setup is done properly you'll get a nice reliable power increase.

 

I still haven't seen what exactly it is that the OP is wanting to do to add this power. That does make a difference...

 

He said a turbo in post #5.

 

You're right, skipped right through it...

You have the right idea, I think it would be fine, esp with the lower boost under load.

At your own risk though, never actually seen it done!
