Prochargers are a serious hoot on a bb.. the instant on torque is a near sexual experience.. I can see the advantage to the slight turbo lag getting off the line for a turbo though.. I dont drag race but it would seem an advantage. Beyond that the procharger has a very predictible power curve all be it exponetial especially after 4K rpm.. but in the interest of harmony.. I sure dont have it all figured out yet..
