Supercharged Gen2..!!!
Wow.. a supercharged gen2..last time i wrote about a DIY Turbocharged Proton Gen2 and this time i'll reveal you a gen2 with a DIY supercharger.
Superchargers and Turbochargers
A supercharger is any device that pressurizes the air intake to above atmospheric pressure. Both superchargers and turbochargers do this. In fact, the term "turbocharger" is a shortened version of "turbo-supercharger," its official name. The difference between the two devices is their source of energy. Turbochargers are powered by the mass-flow of exhaust gases driving a turbine. Superchargers are powered mechanically by belt- or chain-drive from the engine's crankshaft.
Unlike belt-driven superchargers, turbos rely on otherwise wasted exhaust energy for motivation. Right off the bat, the absence of belt-drive parasitic losses means that turbo engines enjoy a 10 to 15 percent power advantage over similarly boosted supercharged engines. And contrary to popular belief, turbos by virtue of their internal compression ratio, also offer more thermally efficient compressor characteristics than any positive-displacement blower. This means they heat the air less during the compression stage. Cooler air means more oxygen content, which, as we all know, means more power! So does this mean that turbocharging is always the best form of forced induction?
A turbo-lover would insist, "Of course!" while spewing out dyno results, outlet temperature measurements and references to every winning abnormally aspirated race car of the last few decades. The supercharger, on the other hand, would take much offense, citing the existence of dreaded turbocharger lag, slam-bam power delivery and unacceptable exhaust restrictions. But the truth is far more beguiling than most people think.
By the way, "a picture worth a thousand words"..

Do you know where can I find a workshop doing this supercharger modification. Thanx
