For stoplight to stoplight racing, around town, off idle races a posititive displacement has been much more fun than the cents I've owned. My cents were only fun from a roll and highway speeds.

If one wants the first scenario and plans on staying with 8-9psi, then a roots will be fine. 12psi can work, but then your on the very edge.Port the blower and get away with 14psi. L's can dip into the low 12 sec 1/4 with a ported Eaton. Minimal supporting mods are needed.

For me 8psi isn't enough, in fact 12psi isn't enough, so I plan on upgrading to a KB.

If Whipple has a kit available and I had an N/A F150, that would be my first choice. I take that back, A turbo would be my first choice. Problem is CA has strict emission laws and I don't want to be pulling the turbo off come smog time.

 

I have a 2000 ford f-150 SC 5.4 4x4 , modifications done K & N fuel injection kit, JBA Headers with bassiani cap back and 4 - 10 gears looking for a supercharger Apparently the only thing available is a inter cool procharger with 42 pound injectors and 90 MM mass airflow or the KB kit any suggestion

 

For the F150 2v 5.4, choices include: Allen (Magnacharger), Holley and Lightning supercharger assembly roots kits; Kenne Bell twinscrew kit; Powerdyne, Vortech, and ATI centrifugal kits; Pro Turbo, remote turbo and custom turbo(s) kits; as well as an electric powered roots kit...I think.

Some are no longer sold new, some have optional or aftermarket intercoolers/heat exchangers, some can go very high in boost, some provide peak power faster, some create more heat, some are more reliable, some are easier to tune, some kits cost more than others, all kits require fuel modifications, all kits require computer tuning for higher than stock boost levels, etc.

To help you decide, determine:
Max. amount of money/credit can/will spend?
Do you plan to keep the engine/trans. stock AND intact?
Is this a daily driver or weekend toy?
What is your priority, stop light or highway acceleration?
Do you live in a hot climate?
Do you plan to tow on a regular basis?

See? Its an easy and simple choice to make!

 

Its not only the daily rider but the work truck as well
I want a decent low end tork inter cool supercharger kit something that will spin the tires I don’t tow anything right now but you never know I don’t race but every now and then I like to act like a juvenal I don’t plan on going more then the supercharger, injectors. mass airflow and trans upgrade I hope

 

Since you already have a 2v 5.4, your already "half-way" finished with the lightning supercharger swap. This system holds the record for the fastest late model F150 race trucks AND provides instant and lowend torque, proven in thousands, if not millions of vehicles, oem quality and reliablity, ability to bolt on several different roots, twinscrews and turbo units to the system AND its intercooled with many aftermarket mods and accessories.

Wow... Go on vacation for a few weeks and miss a thread!

Fatherford, Yes, at Temple it ran a 15.15 with a 2.3 60ft. Power is 360/412 right now on our stock tune with less than 2000 miles on the motor. Our 04 FX4 4x4 w/20k mile ran a 14.43 at Milan back in October with the exact same setup and is posting better dyno numbers. Happy to post that time slip.

But, unlike some competitors, we're not going to be "creative" with our numbers and are going to reflect what the average Joe with the average truck would see through the truck's lifecycle.

Between the monstrous 22's on it and cartin' around the hitch and spare, there's 3 tenths right there.

Here's the excuses, er... facts I tossed out at you at Temple. The motor is tighter than crap right now. It's also a bone stock tune running 9psi, No different than what you'd get from Ford IF they actually made it...which they don't. Considering the extra bulk being hefted around by the 06, I don't have a problem with the time.

My advice would be to concentrate on the power numbers being made vs the time's being run.

Are you going to be impressed more if we bolt on headers, exhaust, race tune, 18" wheels, drag radials, strip it down and run in the 13's? What's the point? The 5.4L 3V motor is in so many trucks you can dial your performance to your own tastes.

Within a few months, we'll be re-running the trucks with all the go fast goodies and tunes and yes, the numbers will be more impressive, but at a cost...as always.

Speed costs money, how fast do you want to go...
