Mr MXSteven,
Can i ask for some info?
THis supercharger using wat management for fueling and ignition?
How many boost can run without touching internals?
Lets say engine is Wira 1.6?
And lastly, after Supercharging, how many hosepower on wheel will gain?
Thanks so much in advance!

There are many components that go into making a complete supercharger system - mounting brackets, ignition controller, fuel pump, etc. okay now we look at only one component of a supercharger system - the supercharger itself (sometimes called a "head unit", "compressor", or "blower"or whatsoever people called lah). All superchargers, except turbochargers, are driven via a pulley that is connected either to the engine's accessory belt, or to its own belt that goes directly to a crank pulley. This is where the similarities between the different supercharger technologies end.
supercharge has a mere 5 to 20% power increased over the standard vehicle engine. it is designed to give managable increase power and torque to the standard engine over wider driving range (speed 80kph / 2,000 rpm to 6,500 rpm)
super charger does not need to alter the internal engine parts. There are two reasons for this. First, the roots supercharger does not compress air - it only moves from the intake port to the discharge port (i.e. it is the only supercharger design with no internal compression ratio). All of the compression is done in the intake manifold. Laws of thermodynamics kick in in favor of supercharger designs with an internal compression ratio (centrifugal and twin screw) because they do less work on the incoming air charge. We will leave the mathematics of this phenomenon to a later (much more boring) discussion. Another reason roots superchargers create higher amounts of heat is because they tend to carry some of the compressed air in the intake back into the supercharger because it gets trapped by the rotating lobes that are exposed to the hotter air in the intake manifold.
i hope you understand what im saying, i just share my 2cents of experience
