Yeah, i'm done with this thread too...but superchargers are not for imports. That's the bottom line.
And a smaller pulley WILL create more drag on the engine, it's like bike gears, plus the fact that it takes more and more energy to compress more and more air.
Go ask any performance shop worth it's salt what they would reccomend for a 4-cyli car. They will tell you that you should go turbo, because the power benefits outweigh the disadvantages of extra heat and "lag..." which actually lets your car get off the line without spinning. The weight transder and tire make-up is all wrong for that much torque off the line.
BMW put a supercharger on a Mini Cooper because the Mini cooper S was not designed to be a drag car. It was designed to have that "instant power" off the line, which provides this daily drivable power that is evident in Mini Coopers. Same thing with the Benz's...they aren't designed for people to go ripping up to 8k RPMs, building boost pressure, for maximum hp. They are designed to present drivable power, and Mini and Benz both decided that maximum power was not the idea is this situation, and they would prefer driveable power as opposed to maximum power. In this case, the supercharger wins. But how many of you boost to enjoy "driveable power?"
Supercharger kits designed for the smaller 4-cylinder cars by companies such as Edelbrock and Jackson racing make superchargers for these small cars because it is what they do best. They have just recently expanded into the sport compact field, so they do not have the best turbo kits together. It's a way to make money, that's all. They draw off what they know after tuning muscle cars for so long. Just because they offer a kit, as well, doesn't mean it is the best application for the car. Why, then, does AEM make a short ram intake for my Integra? Obviously not the best option, but it's available.
Well, I'm done with this as well, hope everyone got some good info on the ongoing debate between turbos vs. superchargers.
