any one put a super charger on a f-250 with the 5.4L wondreing what kinda of a differance it makes power and milage wise

 

It can be done, I have a 99 F250 to and we were also considering putting a used lightning supercharger on it. The only thing is its going to cost you, with used parts you might be looking at atleast $3000 total. The charger its self is pretty cheap, I just found one for less than $600.

 

is it really worht it though u think?

 

It depends on the type of driving you do. I wouldn't recommend a blower for a towing/hauling application because the boost doesn't come on until, or close to, WOT. If you're a fan of WOT blasts, then they're loads of fun, and tend to leave you grinning long after the ride is over.

Many of the factory kits are bolt-on and go types. If I remember correctly, the ProCharger kit doesn't require any tuning because of the intercooler it comes with.

 

they pretty much only boost then at wot nothing happens up to then really?

 

For the most part, yes. However, It really depends on the pulley combination. In some cases, spinning the blower faster will allow you to see boost levels at 1/2-3/4 throttle. Spinning the blower faster will make even more boost at WOT, and tuning and fuel system upgrades are needed to allow the motor to live as long as possible.

 

i was looking at a vortec kit anything known about these kits has a 3 year warrenty and says it will improve gas miliage also

 

Vortec's make good power. They flow a lot of air.

Power takes fuel. Put a blower on your truck and drive it to take advantage of the power increase and you won't see an increase in MPG. If I baby it, I see 14 - about where I was before the blower - but I didn't spend all that time and money to drive it slower than I did before the blower.

The older Procharger kits had an FMU to increase fuel to the engine, I believe the newer kits have new injecots and a tune that you upload, tough I could be mistaken. Either way, you need a way to increase the amount of fuel to compensate for the increase in air.

IMHO a custom tune with larger injectors and a larger fuel pump will maximize your power gains. If you spend the dough to get the hardware, and put all that time into installing it, go the extra mile and optimize your tune...IMHO.

 

where do u guys suggest getting one and what kind of kit do u suggest

 

WOW?!?!?!

No boost down low something must be wrong. I installed a 03 lightning system on my 99 Expidition JUST FOR TOWING.
First low end increse is the reason for supercharging over a turbo (a turbo needs exsaust pressure to work). Superchargers work off your spinning crank and th potential for boost is always there just waiting for the butterflies to open.
Next as for gas milage in daily driving I went from 9 to 12 mpg, on highway I went from 12-13.5 to 16-18.9, and towing from 6 to 9-12 (have seen as high as 16 towing)

I have put over 3500mi this summer on this build and have had NO reliability or driving issues. It however a proper tune is very improtant for good results. This was the hardest part of the project becaus there is alot of smack talk out there and it is hard to find a tuner who knows that some people drive more than a quater mile at a time.

Hope this helps

i found this on ebay does anyone know if it will fit on my 1999 f-250sd with teh 5.4 and will i need a larger fuel pump and computer work done also how does the belt and stuff get run any help would be greatly appreciated thanks

 

Yama, you need to look at our other ongoing thread about this... it basically answers most of your questions: https://www.ford-trucks.com/forums/5...superduty.html

The Lighting or H-D blower/manifold is direct bolt up to your engine... it's all the other auxiliaries that become a custom fabrication. The fuel pump is dependent on what your goals are... you can use a fuel management unit or a booster pump to achieve the same results. Belt routing will be fine, identical to the blown stock 5.4s.

And that is the main reason why a (properly sized) turbo will out perform a blower for towing is because it has the potential to create full/max boost at part throttle, under heavy load conditions. Exhaust flow, and the expanding heat is increased under these conditions, and this is what spools a turbo up...fast. A turbo is not as sensitive to engine speed as a blower. A blower (with the same max boost potential) can not/will not compare to this under heavy load/part throttle conditions because it is no where near as load sensitive as a turbo, and parasitic loss isn't an issue (as compared to a blower) either.
A blower will move more air (than a stock N/A application), under heavy throttle/towing conditions, and power gains are realized...I will agree to that. But if you're implying that a blown (roots/twinscrew or centrif) will out perform a turbo application for towing/hauling, then I have hard time believing that. However, if you have some comparison data that proves otherwise, then I am all ears.
