Hi Folks. Has anyone ever taken a lightning blower assembly and put it on a none lightning eng.example I have a 2002 5.4 triton and a fellow on ebay has a complete blower setup.I always thought that you would have to change computers and install a hiflow pump. Any info would be great!!!!!!!!!!

 

I've not done it and only briefly looked into it. From my research, the fuel pump, ECU program, and whole intake setup would need to change. I also think the injectors would need a change. The Lightning also uses a forged crank and pistons... if you don't, it'd be a really good idea.

My truck is a 2002 f151 e/c Stage 2 Jack Roush Edition,The truck had an option of a vortex blower setup. My truck did not have this option and I have looked into pricing out the vortex and it was almost 5500.00.So I checked on ebay and I fellow had a complete setup Intake manifold ,injectors ect. and only 1600.00us.A little bit more resonable,but not a true roush setup,but what the hey. boost is boost. My truck has only 7200 kilos(4800 miles) So I really don't want to pull the engie out and start a rebuild. Thanks Rick

 

Old ford guy, I was told that non lightning/Harley 5.4's have a lower compression ratio than their blower fed brothers. Does anyone know if this is true? That would also be a consideration before supercharging A n/a 5.4.I am also looking at supercharging my 5.4 with the lightning kit and was told that the higher compression ratio would not work.

 

I believe the '99 and up Lightning has a 8.0:1 compression ratio, where the '99 NA 5.4 F150s have 8.8:1...
The reason for the lower compression in a supercharged motoris to give you the ability to boost the charge more, making more horsepower.

If you look up supercharger technology or tech on a search engine, you'll find how each works and which is best for your application. IMO and from what I've read a centrigual charger is best unless you plan on upgrading the engine internals.

Kerry, with that much diffrence in compression, would a lightning setup tear up the n/a engine? How is the centrifigul charger safer?

 

From what I've read, a stock engine should only see, at most, 6 psi of boost. There's something about the designs, but the centrifugal produces it's pressure in the head. The roots and the screw (iirc) produce it outside so you have more of a chance of getting a higher boost than the engine would like... boom. That search I listed will give you way more technicalities than I can recall... that's your best bet.

By the way, I think the Lightning superchargers are screw types. That's why Ford went with lower compression in the Lightning.

That makes sense, and sounds about right......If there is something i'd like to do, it'll tear up my truck!!! LOL! Thanks for the info.
