Does anyone know if the supercharger and intercooler setup from a 2004 Cobra would fit the 5.4? A friend of a friend is selling one for very cheap and if I could add that on thx guys.

I didnt see anything made for 2004 and up not to mention there a little more than i wanta pay most likely i could get this one for less than 1000. So does anybody know about the fitment or if it will not bolt right on how about some minor modifcations?

 

No, it won't fit a 5.4.

- the 4.6 and the 5.4 have two different deck heights, so any 4.6 manifold is a lot narrower.
- the Cobra 4.6 is a 4-valve engine... the intake ports are entirely different than a 2-valve 5.4 so it won't match up.

There are aftermarket considerations.... none of which wil be particularly friendly to longevity (the Cobra engine is built for the stress of supercharging - forged pictons and Manley H-beam rods, ARP fasterners, special cooling) of an otherwise-stock engine.

A better choice for a swap might be the Lightning engine... I missed what year your truck was but for previous-gen F150s it should be all but a bolt-in - and don't forget the special heavy duty Lightning tranny and driveshaft. There are entirely new Lightning engines available from Ford and several other sources.

Since this is a 2004/2005 F-150 Forum, one would assume that the truck in question is most likely a 2004 or 2005 F-150. That would make his 5.4l heads the three valve variety. If I owned a new F-150 (which I do) and wanted a supercharger (which I also do), I think would look into the Whipple Charger (which I have done) instead of screwing around with a complete engine/transmission swap. As I am sure you are not doubt aware, there is considerably more to a modern-day swap other than bolting in the engine/transmission.

 

Yup, and another good point is that the current Eaton supercharger isn't really a very good piece... it's very inefficient and makes a lot of heat.

And, I missed which forum this is, that's what I get for stopping by the side of the road to type in a quickie reply. In an older previous-gen F-150, it'd be fun to bolt in a Lightning engine (and, as you point out, the tranny, the processor, the MAF and intake, the exhaust, and all the other little things that make the Lightning such a good package - including a suspension). And, of course, then you have to take on servicing it yourself. There aren't too many dealers where you could pull into service with something so different from stock.

Of course, for this F-150, it's an unknown how you'd interface the electronics of the older engine with the new truck (the processor of which is an entirely new an incompatible design).

I think there are an additional couple of supercharger packages in the works for the F-150. I believe that SEMA this year will be a very good year for the F-150. I'm hoping to get there myself...

the F150 in question is a 2004 and im not looking to run too much boost maybe between 6-10 psi nothing thats gonna screw things up. Whats the price on that whipple i found the website but no prices?

 

As far as I know, and I've being keeping an eye out, Whipple hasn't released their setup for the 2004/2005 5.4/3-valve yet. The website says the target release date is summer 2004 but an email I received from them in July said it wasn't quite ready yet. I believe the price will be in the $5k range for the complete package. if anyone here has more recent information, please post it.

 

I would also be intrested in adding the whipple supercharger to my truck. I called them but at this point they have not responed.

May have an output of 112 HP and 90 in the torque range.

 

FYI - A Stock Eaton blower is less than $600 on the Cobra forums...

I am a new owner (about 1 week) of a '04 F-150 XLT supercab w/5.4L.

Anyway, I also own an '03 Cobra for which I have ordered (and am waiting to arrive) a Whipple to replace the stock Eaton.

I am still not very familiar with the 5.4 yet, but the blower setup on the Cobra does not appear to be a simple swap to the 5.4L from what I have seen so far.

I would suggest looking for something specifically designed for this truck rather than adapting something else.

As far as Whipple goes, their sales department definitely has issues with customer support. Hope their tech department is better!
The blower was about $2800.

I can try to answer any questions you may have about the stock Cobra setup.
