I have a 2005 F150 4x2 regular cab long bed 4.6L auto. I was wondering how this truck would stack up against a Dodge 4.7L, Toyota Tundra, or an F150 5.4L.
I would assume I'd be able to beat 4-door models of these trucks due to their weight. By the way, how does the 4.6L horsepower and torque look compared to these? I forgot to mention I have 3.55 gearing.

 

If the Dodge has the 20" wheels and the 3.92 axle, he will run out of sight from you. The 5 speed auto makes that much difference with the axle help as well. The Tundra in a regular cab will smoke your Ford as well. Both of the competitors engines are mighty strong for their size. Your Ford, however, on long runs will be running when they are refueling. Against the 5.4, personally I think the performance of the 5.4 is disappointing. While my 04 4.6 won't stay with one in a quarter mile, the 5.4 is just barely in front. All things considered, the Triton will probably out live the others including the heralded Toyota. While durability is the strong point of the Ford engine, performance is not. Rarely can you have both.

 

yep your little 4.6 is strong, but there is no replacement for displacement. 3.55's are not deep gears when you consider a 3.73 being really common, not to mention a 4:10. you should get great fuel mileage though.

 

You will lose to a 5.4L F150 unless it is a '97-'98 model year.

The Dodge 4.7L will edge you out, mainly because you outweigh it by a couple hundred pounds (in comparable trim and configuration) and the Dodge has a 5 speed auto versus your 4 speed.

The Tundra should beat you also, because it is a lighter truck with a little more horsepower & more torque.

However, none of these are problems a Kenne Bell on your truck won't fix.

 

Sounds cool guys. A supercharger may not be a bad idea...my truck is XL trim, just a basic work truck. Except for the dumped Flowmaster there'd be no indication of any performance whatsoever, if I left the work truck appearance. That would definitely be a sleeper worth having. What are the stock numbers on the 4.6, anybody know?

PS: My gas mileage isn't too bad at all. I got 14.71 mpg on the first tank, and I'm hoping for more once the engine breaks in (I'm at 330 miles right now).

 

The stock numbers are 231 horsepower and 293 lb.-ft. of torque.

With a Kenne Bell your truck will have all kinds of torque.

 

So call me crazy but I thought it was quite powerful right now? I had a 1990 F250 with the 351w and 4.10s, but this truck moves quite a bit nicer, and handles hills better. It probably won't haul weight as well though. I always expected 3.55s to be slower than this from what I've read. What would I be looking at powerwise with the supercharger?

 

Yea, your truck definitely has more horsepower that a 1990 351W. Not too far off on the peak torque really either.

With an s/c I don't see why you wouldn't hit 300 or more at the wheels, compared to the 180 or so your seeing now.

Thanks Admin Tim here

 

300 at the rear wheels? Thats enough to take a Hemi. If I add headers, intake, underdrive pulleys, and a chip along with the supercharger, would I be relatively competitive vs. other trucks? Furthermore, would adding lower gears increase acceleration? 3.73s? 4.10s?

 

Lower gears will give you WAYYY better acceleration. those highway gears are killing you. Get the 4:10's.

 

4.10s are tempting. What would the cost be? I know it won't be bad, as my truck is 2wd. What kind of hit am I going to take in the mpg department?

 

With that setup you should be competetive with or faster than a stock Lightining, depending on how much boost you run. Hemis and Titans won't be able to keep up at all.

You'll lose 2 - 3 mpg tops with a 4.10 gear swap. You used to be able get a set of 4.10s for an 8.8" from Gene Evans Ford for $139, I heard they went up to about $200 recently. The labor varies alot, the Ford dealership will want ~$300. If you can find somebody to do it on the side it can get alot cheaper.

Try to stick with Ford Racing or Ford gearsets, Richmond and other aftermarket gearsets tend to be a little noisier.
