I am with MSP - A twinscrew Supercharger -
Whipple, Kenne Bell, one that is not centrifugal. The stability of a supercharger for increased power with little concern of bottom-end engine rebuilding....well....here is a little snippit from Kenne Bell on the differences in the SCs and their boost scales...
"All supercharger require you use the highest octane fuel available. 92 octane should be adequate for any 5-6psi kit. 8psi centrifugal kits are promoted by dealers and performance shops as they tend to develop a little more boost in the low to mid range than 5-6psi centrifugal kits. However, ignition timing must be retarded. That is why 8 psi kits from all the various kit suppliers include an ignition system and an ignition retard - which "retards" timing and, of course, reduces horsepower and performance. NOTE: If advancing timing improves performance (up to 16 degrees) retarding timing conversely hurts performance. In fact, what you gain from 2psi (20-25hp) is lost by retarding timing 4-6 degrees. The Kenne Bell 6psi kits (for GT) actually outperform the centrifugal 8psi kits because of higher boost at any rpm and more boost at the shifts. Now we all know that there are ways to run 8psi and higher boost levels with 1.) 24, 30, 35, 40, and 50 lb. injectors, 2.) ultra-high fuel pressure, 3.) lower compression ratios, and/or 4.) higher octane fuel or fuel boosters, but that was not the 92 octane question. Also keep in mind that modifications 1, 2, and 3 are not "50 state legal". Therefore, if your goal is to run 8psi and develop 20-25 additional horsepower with 92 octane fuel, consider adding a can of black bottle 104 brand Octane Booster at $6.00 per tank full. $100.00 for 5000 miles of driving is cheap performance by some standards."...
I have engineering concerns with Turbos and NOS kits unless you are going to functionally re-engineer the engine to ensure that you do not cause a pressure blow in the manifold or cylinders. As with most modifications to the modulated engine..one at a time is a good rule to go by unless subsequent chagnes are required to ensure that you do not encounter engine failure, that way if something goes wrong, you pretty much know the cause.
Tuning will be required. I would suggest that due to the EEC-V/PCM table alogoritims you purchase a kit that has a programmer that can upload the appropriate data so that the SC performs as intended. Therefore, unless you can program a custom tune, "model swapping" a SC from an Explorer or Ranger application will not be able to take a handheld device.
I do not feel that without major engine internals and modifications to the Unibody chassis, a transmission swap (T5 has a max TQ cap at 175-300 dependant on specific unit), rear end, diff, gears, that the max numbers cited of around 500 could be handled by the engine design. Even the 3-V has a week point at the stainless steel ring in the upper piston ring.
On a side note and to throw some flames on the fire, It will be interesting to see how the new 3V-V-8 engine manages the increases in power. The new cylinder heads feature two intake valves and one exhaust valve per cylinder. And, although this new 3V system has a SOHC, the addition of variable cam timing should improve modification performance by advancing and retarding the existing cam profile.
The redesigned intake manifold should also accept SCing well. The ports on the 3V are designed and have been machined more like the 4V; in that they are long and slender rather than the round style we are used to with the previous 2V 4.6L.....Without going too nutty here... Ford has accomplished with this 3V intake manifold set-up what the "older" 4V Cobra Intake Manifold Runner Controls did..
Okay....back on task folks.... I am tired and will do some more research tomorrow after work.

P.S. I would not change out any parts in my V-6 until warranty expires. Magnuson-Moss Act will not prevent warranty exclusions due to major modifications that cause component failure. BUT, that is just me and I only have this as my daily driver....
By then, hopefully Ill be out of college and in a better position to do the work on the car financially. But now we're talking 4-5 years down the road already. 
Keep up the fantastic work, it looks awesome!
