I am very interested in dropping one of these on top of the 418 at the end of the summer since I will be able to work ALOT of overtime sicne I wont be going to school and I like the idea of 850-900 crank hp wih instant boost and the possibilitie of more with a pulley change and then nitrous on top of that
