I drive a Jag XKR and my motor's supercharger doesn't look like that.
Wish it did though.
There are two main types of superchargers:
1. Roots - what you see on the Mad Max car
2. Centrifugal - what you see on this 1966 Shelby GT350 Mustang:
I am using this picture so you can easily see the difference between the two types of superchargers
The roots does not have to be on top of the engine. It can also be to the side but the main component is that it uses rotors inside to create the pressure (boost) and the fuel and air are being fed through the supercharger:
The roots supercharger can also be a low profile - like what Ford uses:
Air and fuel are mixed before they enter the supercharger.
The centrifugal is a pump that pressurizes the fuel source (carb or fuel injection)
Your Jag looks like this right?
That's a centrifugal setup and it is using liquid intercoolers to cool the pressurized air before it hits the fuel injection. Pressurizing air raises it's temperature.
As far as engaging or disengaging a supercharger with a clutch type pulley? The belt will continue to spin no matter what. The whole idea with the Mad Max setup was to inject "drama" into the scene. Hit the button and the belt starts to move telling the audience . . . here comes the horsepower.
A supercharger usually adds 40% to 50% more horsepower over the basic horsepower rating of a non-supercharged engine. So a 350hp engine when adding a supercharger results in between 490hp and 525hp.
The 1966 and 67 Shelby GT350's had 306hp (from a Ford 289 CI engine) with the supercharger (a Paxton) they netted out to about 400 to 425hp
This is the zenith of a supercharged internal combustion engine - the Top Fuel 500 cubic inch Hemi engine that is supercharged, fuel injected and running on 85% nitromethane . . . making 8,000 horsepower
They consume between four and five gallons of fuel during a quarter-mile run, which is equivalent to between 16 and 20 gallons per mile and have a the fuel-line pressure of 400 to 500 pounds, about 20 times greater than the pressure on passenger-car fuel pumps.
Those two red MSD units are magnetos. There are two spark plugs per cylinder. They put out enough amperage that you can weld metal
