FORD V10 MPG

[Rich W.]

I opened up my air intake. The one thing I noticed when on the highway is the transmission held it's high gear longer with out shifting down. Not long enough to record MPG.

That was one of my goals - to reduce the constant down shifting and make it pull a little longer on a higher gear on grades. With 5 star, Banks, and a free-flow intake (forget which one) I made some real progress, but when running full throttle up a hill the intake was loud.

With those upgrades what was your MPG increase?

We added a 5 star tuner to the E450 V10 we recently traded in.

As mentioned for advantages, easier to control downshift on grades etc.

We also had an increase in mpg after install - about 10% is what we saw with no other mods in play. We run between 60 and 65 on the highway normally.

From 7.7 towing our toad to 8.5 isn’t much but did make a difference for us. That was measured across the same route and about the same conditions before and after.

The Canyon Star, using Prem Fuel and quality synthetic oil, averaged 6.7 mpg over the last 25K miles. Typically the RV was at max weight, 30,000 lbs, towing a sedan on a dolly. We traveled coast to coast and border to border several times.

Thanks for all your input. For a starter I am going to do a cold air system, upgrade the exhaust to a performance type, get a tuner, and look into the Airtabs, semi truckers reviews are saying they reduce drag increasing there MPG. I have seen a couple on coaches, but not able to talk to the owners. Any other suggestions.....

When I first got my Georgetown, it got about 6.5mpg at 55 mph. I made some modification to it and now get 8.5 to 9 mpg at 70 mph on my last trip of 2500 miles. I drive the same route a couple times a year to our "GO TO PLACE. "

First I did a cold air intake, a simple scoop at the front grill, directing air thu a dryer vent metal flex pipe to the intake of the stock air filter.

Secon, and the greatest improvement, was to shorten the exhaust pipe. Mine crossed over after the muffler to the driversders side from the passengers side. It now exits at midway on the passenger side. No increase in noise and about 10 foot of pipe and 100 lbs. I have also noticed less downshifting on steep grades, which I am smart enough not to be concerned about dropping speed down to 45 to get over in an attempt to keep the engine RPMs as low as possible. Remember your engine develops max Horsepower at about 4500 RPM, but it sucks a lot of gas.

Third was an filler between the front grill and radiator support at the bottom of the radiator and an air dam below radiator cross member. othe front bumper, this improves air flow thru the radiator and, I believe, reduces front end air resistance. (not wind tunnel tested).

Make sure tires are inflated to 85 psi. Lastly, plan your trip to avoid long steep grades if possible.

Are you talking about a straight pipe under the MH, or exiting out the side of MH

Picture explains all. I included one of front air dam.

Just wanted clarification as one way isn't safe at all.

Absolutely out the side as exiting underneath the coach would allow for dangerous gasses to enter inside. Illegal in most states.

I'm back, I want to just add to what I have done to my ford V10. I cleaned up my cold air intake and added a K&N large cone intake filter. Was planing to change out the ford stock catalytic converter to a legal high flow converter like I did on my last rig. But I researched what the flow restriction was on them, To my surprise the restriction on the stock unit is 1.5 to 2 PSI at full throttle. Not much difference with the performance cats, so I am staying with the stock unit..I am now waiting for my performance muffler to come. When the new muffler
comes in from Summit, I will change out the stock muffler for the high performance muffler. Can't wait to hit the road to see what kind of improvement I get..

I had a 38’ Georgetown on a 2016 chassis with the 6 speed and seen average 6.5 for the 40k miles I put on it.

I get 6 MPG with my 34 foot rig with the V10. What can I do to improve the gas millage? It is a Thor Hurricane.

Seriously ? How much of an improvement are you expecting looking for ? Just asking

 

[BGMAC]

I added the Tuner to my 2011 Thor Hurricane 32 ft, and I did get an increase in mileage and better shifting. Staying around 60mph is the key. I believe I got 8 if I remember right. I have a 2016 Georgetown 38ft and I plan on a Tuner upgrade.

If you consider noise an improvement then go for it.

I installed the "Ford Ultratune", from Ultra RV, in my 2020 Newmar Canyon Star, but it's on a 2019, 26,000GVWR, F-53, V-10 chassis!
Overall performance seemed to increase, especially initial acceleration, and definitely improved the shift points, reducing the need for more frequent shifts.
Fuel mileage seemingly did not increase, and stays about 6.6-6.9 mpg towing a 2017 GMC Terrain. Without the Terrain, I got 8.2-8.5 mpg!
In my opinion, the best results were in the change of shift patterns, & not upshifting/downshifting with as much frequency!
Nothing to do with performance, but I removed the "dog house", and added "Dynamat" Insulation pad, and noise reduction pad, and as a result, significantly reduced the engine noise in the front of the coach! A GREAT improvement!
