i am seriously thinking about putting a supercharger on my truck!! im 19 and in the marines here in yuma az , and all i have to do is mess with my truck when im not workin on jets! every one gives me **** because i dont want to lift it 8" and make it a mudder!! ill prolly put a leveling kit on it thats about it! but i would like some pros and cons on supercharging because i dont want to make a blind decision.. am i going to have to get a different tranny, rearend etc. any feed back would be great! i also am having custom exhaust put on it next week coming out in front of the wheel, cant wait to hear how it turns out!!

Pros --- well, that's obvious.

Cons - gas mileage goes to hell.

You can stick with the stock tranny and rear-end.

ah...man it has a major impact on gas mileage? i figured a litttle bit but not more than a couple mpg!

Roush rates a supercharged 5.4L at 11 mpg hwy, 8 mpg city --- and that's with only 6lbs of boost.

I say sense you have the money just go a head and spend it on a turbo kit. you won't see to much of a drop in mpg plus who doesn't like the sound of an airplane?

I have a Roush charged 2008 SCrew, with 5.4L engine. I get 16.5 or so overall mpg, with the ethanol blend. 17.5-18.0 with 100% gasoline. That's with fairly spirited daily driving. Obviously, if I keep my foot in it, MPG drops precipitously. I couldn't be happier with my SCrew.

Are you hand calculating this, or relying on the computer display? The computer is notoriously wrong, especially if a charger is added. Roush rates the supercharged F150s at 8 mpg city, 11 mpg highway.

why go with one, why not twin turbo?

FTE Ken · #13 (**permalink**) 05-14-2008, 07:29 PM

Good question....

1. Increased cost.
2. More boost means having to do piston and bottom end work to beef up the engine. Even more increased cost.

yeah that is true too, would the reg 5.4L blk withstand a single turbo

Ya it shouldn't be a problem as long as u keep it 8lbs or under. I bet it would have c6's running for cover!
