I am on the verge of getting an RL and i am kind of weary about the whole supercharged setup. I know it is reliable,but for the simple fact that everytalks about how u can't upgrade to a smaller pulley because of the heat. I have heard a lot about having to upgrade superchargers. I was contemplating about just going turbo and be done with it. I was just curious about the distance between the firewall and the engine?
