Default Tow 10Klbs with F150 5.4L - Need HP

Hey Everyone,

I need to increase my HP on my 2003 F150 5.4L to get it to tow 10K lbs comfortably. The only mods I've done to date is a Magnaflow Catback SS Exhaust and a K&N CAI air filter system. I'm looking to get a performance chip and maybe install an electric fan for the radiator but I wanted to know what others have done to increase the HP to reach the 10K need.

Well the chip is a start, but i wouldn't tow 10k with an F-150 regularly. I imagine stuff will start to break, including the transmission. and that's $3500 to fix. Sell it and get a diesel if you have to tow 10k alot.

10,000 pounds with a 5,000 pound truck... thats a recipe for disaster...... I would never even consider it.. and never on a regular basis....

Well, I'm looking to buy a travel trailer that is 7800 lbs dry weight. I need to wait two years before I can upgrade to the F250 PSD. We are looking to travel less then 200 miles per trip and about 4 trips per year. I already pull a loaded trailer that's about 7000 lbs pretty well. I'm sure the new trailer will be under 9000 lbs but I was looking to make sure I could do it before making the investment. The tranny already smoked about 50K ago and I put an upgraded valve body and plates in to while replacing the sun gear assembly. I have 110K on the odometer right now so I'm not looking to be stupid and burn it up.

I recommend saving your money from the mods, but the f250 firstx then the travel trailer. It wont be fun going 200 miles with that.

You need more torque. Gear the truck lower (4.10 if you don't already have it). Try a Bully Dog GT, saw promising distance increase on the pull sled in a test that was aired on Horsepower TV not too long ago.

Sell it and get a 250...please

Your F150 isn't rated anywhere close to towing 10K. Do you even have a brake controller?

The new 150s max out at 11,300; so towing 10k regularly is still a stupid idea.

Trust us. To make your truck barely capable. Just what i would do.

Regear to 4.10's($1000-$1500)
Tuner(vary's, good ones are spensive)
CAI($200)
Mag hytec tranny pan, diff covers, and oil pan, plus the extra oil to fill the high capacity(around a grand)
Aftermarket tranny cooler
Tranny temp gauge
E-fans
Underdrive pulleys(lose a little power to accessories)
Bigger leaf springs(looking at 500-600)(rides way rougher)
Upgraded brakes
If you want a little more umph in tow, a supercharger or procharger. Again, spensive.
All high quality engine parts.
Possibly a bigger aftermarket radiator


Thats all i can think of. Now, most of this stuff comes stock on a super duty. Again, go sell the 150, buy the 250, then buy the trailer. Your literally getting the cart before the horse here.
