Well what onebadcoupe is trying say is,remember your turbo spins at hell i dont even know like 20K maybe someone can tell ya if they know.so if you hooked a TINY pullie to it and went off a belt system it will have to make it spin as fast to bring in the air to boost the system.and real charger has a larger Wheel to draw and force in the air just like a supercharger thats why the boost is always there..so if you did it you would have to find and match Rpms with everything other wise if the pullie is to small or to big it could fuck something up
