What would the feasibility be of installing another supported bearing(say from a go-cart axle) closer to the supercharger when you get the new one from vortech? (shouldnt be too difficult to fab a bracket to house the bearing.. might need to put a fitting for a greasegun to lube it though.. simple maintenece should eliminate alot of headaches)
This should help eliminate ALOT of the shaft wobble, thus non-treated splines would not be as much of an issue?
