RE: supercharger
If you go onto Prochargers web site, they have a media page and in there they show you a before and after on a 03 gt. 13.67 stock and than 12.13 w/8psi. I'm running a 10 psi intercooled P1sc on my 03.

RE: supercharger
There are several different types of superchargers. Twin-screw and centrifical seem to be the most common. A twin-screw supercharger such as a Kenne Bell replaces the intake on top of the motor. A centrifical supercharger such as the ATI Procharger or Vortech bolts onto the front of the motor. The twin-screw builds boost quickly giving you more lower rpm torque. It bleeds off the excess at high rpm. A centrifical builds boost with rpm reaching peak boost at redline. Both give awesome performance.
Picking one is a personal choice. Is your car a daily driver? Will other people be driving you car? In my opinion, centrifical superchargers are a better choice for a daily driver especially if other people will occasionally drive your car. At low rpm they develop relatively modest boost and behave themselves well in bad weather. I read an article about a twin-screw supercharged Mustang where the author said it was like taking off on glass.He said itmade you believe that buying a set of tires each week was an acceptable cost. This of course was an exaggeration but it makes a point.
I chose a centrifical because my car is a daily driver. My wife rarely gets above 2500 rpm so for her the car behaves pretty much like a stock Mustang. And, I have driven through light snow and ice (although you probably won't see much snow in Florida). I do a lot of interstate driving. At 70 mph my supercharger is running around 1.5 lbs of boost and is putting very little stress on the motor. I still get 21 mpg. But if I want to pass someone all I have to do is down shift and the power is there. Superchargers require 93 octane gas. I was told by the guys at THR that in a pinch you could run 87 octane with a centrifical if you kept the rpm low. My wife accidentally filled the tank with 87 octane gas once. She realized her mistake and put in octane booster but I'm not sure if that really does any good. I drove the gas out at very low rpm.
Of the centrificals I prefer the ATI Procharger. The kit included everything including an intercooler. Any air compressor heats up the air. Motors like cool air. Hot air can led to detonation (spark knock). Detonation tends to burn out the tops of pistons and break rods. Detonation can be controlled by the timing but there are limits. I've read that should not go above 8 lbs of boost without an intercooler. Even below 8 lbs an intercooler is better for the motor.
Be careful when comparing supercharger prices. Some come with intercoolers, some don't. Some are tuner kits (no fuel pump, injectors, or chip), others are complete kits. The great thing about owning a Mustang is that there are a lot of different options to choose from.
