I own a 2005 F-150 FX4 with 5.4l triton 3v, 15" lift, 22" Fuel Hostage wheels, 40" Interco M16 tires, 4:88 gears front and rear, OBX Racing stainless steel long tube headers with high flow resonators, super 44 Flowmaster, cold air intake, PHP programmer, 130,000 miles, all stock internals. Truck drives 75 mph on highway at 2300 rpms. Looking to get some more power out of her without opening up the motor. I'd be fine with 8-10 pounds of boost. Just not sure which route to go. Any opinions would be great. Thanks.

Do you mean "roots blower" or "Centrifugal force" ?

Centrifugal force

honestly I wouldn't waste my money supercharging a motor with 130,000 miles on it. For how many of those miles has it been lifted that much? Those big tires with the addition of a supercharger will kill your transmission. I went through 2 in 80,000 miles on a 2wd 2008 crew cab with the Roush supercharger on it and the first one was within the first 20,000 miles.

I would save up for a new motor, then add the saleen supercharger on top of the new motor. With those big tires you need torque to move it and a centrifugal needs rpm to make boost, where as the roots style will make all the boost basically from idle. The Roush setup was ok, but if my truck had not come with it I would've gone with the Saleen setup. The Saleen is a more modern supercharger system than the Roush. The Roush is a similar setup to the one that came on the 99-04 Lightnings.

lol i was confused about the title question , but now i see what you meant. Not having forged internals and a high compression ratio could put a damper on how much power you want to get out of it. I'd put a whipple on top with some bigger injectors and a custom tune. 8-9 psi should put you around 400 whp with pump gas and regular non-150 lbs tires ha.

What Chicks meant is that procharger is a form of supercharging that uses centrifugal force vs Eaton's Root system.

I agree with the other posts.

Your internals will not be able to hold up to the output of the supercharging. And the engine power gained will not make it down to your wheels.

I'm biased as I work for Eaton, but a roots charger is the only way to go if you're so inclined on your existing motor.

For best performance and less headache, I agree with Tommy and get TVS Supercharger. This is Eaton's newest technology since the roots system. This system is also on the Corvette, Camaro, Cad CTSV and Jaguar.

Your issue at the end of the day is always going to be how much torque you get to the wheels. So if doing a motor swap anyway just get a naturally aspirated V10

Lift wheels and tires were all put on at 90,000. Trans rebuilt wouldn't be an issue so not to worried about that. Was looking at an intercooled whipple twin screw.

supercharger will put lots of pressure on your stock valves, lifters and rings.

Charging HP increase will not equal torque/speed you are looking for

So what do you recommend?
