If you bought a 7.3 PSD engine for another $3800 (dealer invoice give or take a buck) you would not need a supercharger. It comes with the power built in. You might need a $300 (my Hypertech 3 cost $195 including shipping and no I'm telling you who I bought it from!) upgrade, but that is the power you are searching for!
Instead you are going to save $3800 and then invest it in a supercharger? Do you have any idea what your mpg's will be after that modification?

I have been talking to Paxton regarding there
supercharger kit made for the V10. They state
that This kit will increase HP 50% over stock and increase torque 40% over stock. They do say that your mileage will decrease
about 10%. However, it is a bit expensive.
$4,800 for the complete kit.
I am also looking into a Kenne Bell supercharger , but the cost factor and the need to run $$$ 93 octane fuel has me wondering does my v10 excursion really need this mod . any info would be a great help

First let me mention a disclaimer: I do not own a V10 (or Ford for that matter) and I have never owned a supercharger.
Now let me see if I can help any. I have owned a couple of high compression V8's before in older Chevy cars. All a supercharger BASICALLY does is raise the compression mechanically just like domed pistons. This requires the use of higher octane fuel (93 instead of 87). The power it adds is well worth the money if that is all you care about and have expendable income. Newer fuel injected vehicles espically because the electronics allow you to squeeze the most power out of a engine with a larger margin of safety than an old carburated engine. If you live in the real world where money matters, or you have other intrests than "I can burn the tires through three gears!" then a supercharger is not worth the extra $. In a vehicle that gets 15 MPG (just estimating from the numbers you commonly hear the V10s are getting) and you have to start pumping fuel that costs more you will end up spending alot of money. In truth mileage CAN stay the same or even improve with a supercharger if you drive conservativly (the engine is becoming more efficient) but most people will put their foot in it a little more and with a blower strapped on her a little is a lot. Any way you slice it you will spend more at the gas pump due to the octane requirements even if you don't lose mileage. It all comes down to the question, "How much is enough power?"
You could get out alot cheaper with a good set of headers/exhaust and not have to pump premium. The power won't go up as much as if you added the supercharger but I feel most people would find it a satisfactory improvement for the money spent. I have driven a couple of V10s (hauling plants from central TX to northern OK) and found the motor to have good power if you keep the RPMs up. Unless I suddenly were 16 again and had to have the BIGGEST BADDEST car on the block then the only mods I would make to a V10 would probably be headers and exhaust. After all it is a truck, not a Cobra R or Corvette Z06. Good luck whatever you guys do.
I am getting the Kenne Bell whipplecharger
in a few days (well, the mod shop is).
It comes with it's own chip and dash mounted
toggle switch for transmission behavior
("power" / "shootout"). There's also an
optional (or maybe it comes with it) tranny
It runs at 6 psi although you can get pulleys
for 9 psi, but 6 psi is the most you can run
using the *whipplecharger* on a *stock* v10
without detonation. To run 9psi, you'd have
to get lower compression pistons (stock is
9:1) like 8.4:1 that's on the F150 Lightning,
or maybe down to 8:1.
Other superchargers like centrifugal ones
such as paxton and vortech run higher psi
because that max boost isn't achieved until
the higher rpms like 5k, which lowers the
risk of knocking.
As for the mileage, kept at lower rpms or in
the case of the whipplecharger, small amount
of throttle since it uses a bypass valve,
the mpg shouldn't suffer (or at least very
little). But with a heavy foot, it'll
definitely be in the single digits.
Paxton also offers an optional intercooler
with theirs ($2000 more? i think);
Vortech's coming out with a supercharger as
well as another one by SuperCharger
Specialists (877) 794-7697, all soon.
