Big Improvement in Ford F-250 with manual and 7.5l

[Big Dave]

Look into changing gear ratios. That 460 has plenty of torque to push 3.31:1 gears. Slowing the engine down at a given road speed is a very powerful approach.

I'm interested in reading your results from that mod. Please post your fuel log.
I've only managed a 19% increase with my Mustang due to break-in, "adjusting the nut behind the wheel", and adjusting my commuting route.

I sure will keep you guys up to speed on how it does. So far, I have increased HP and cleaner emissions.........but what else do you expect from a water injection unit. I'm hoping the hydrogen injection part pulls its weight and gives me the FE gains.....

I hope money rains down on me from the sky too.

Documentation? Dyno graphs? Emission test reports?
Just curious.

Yeah, I wish. HP by feel and emissions by smell.....tested like a true scientist!!

Yeah, so take it with a grain of salt I guess....

Good to see another TruckinEcomodder

I doubled the MPG's in my truck, an 89 F150 4.9 went from 12 to 25.

How big/heavy of a trailer do you pull? the 460 has its place but seems overkill for pulling a 2 horse trailer.

Why not have the horses pull the truck

My biggest gains are from EOC and 0 idling.

EOC?

I saw you have an ignition kill switch. How is that useful for you?

LoL, Engine Off Coasting; that is the holy grail of hi end ecomodding tips for manual transmission vehicles, I suggest taking a look at the 100 or so ways to get better fuel economy. EOC properly done is VERY effective especially in town.

You will see EOC is listed in the fuel economy tips somewhere. the easiest form is to put your truck in neutral kill the motor and coast up to expected stops from as far of a distance as possible then bump start near the end when you need to regain speed.

A fair warning that you should learn how to do this on an unpopulated road so you can know how your paticular vehicle handles it.

Good Luck
