No you should align the drive shaft 'dead on ' end to end with a lazer dot so there is no misalingment....
Exactly what terry says.. align it as precisely as possible, but I still think you need another bearing(or at least a support) to help keep it that way due to variations in the engine harmonics...
Think of it this way.. even 1 degree on a half a meter is still a variation of aver a half a millimeter at the end... and in those splines that would be enough to cause bad wear... The problem you run into is with it being a belt drive, with a pulley at one end, and thesupport bearing close to that end, the torque on the arm from the tension in the belt due to resistance(due to engine load etc..) of the engines pulley's rotations, will cause the threaded end to "twist" just slightly, and if you are off by even .8mm then after X000 miles, yes even a hardened shaft will show wear.. to the point where your splines will be damaged past the ability to inter-mesh with the splines on the Charger.....
The only good way to run a supercharger off of a long jack shaft, would have been to install a set of pulley's at both ends, driven by belts(cogged or splined), allowing the belts to take up this problem of torque/twisting... but.. they didnt do that.. (do to cost, space considerations, whatever.... ) and youre stuck with splines..... good luckoh well maybe Im just an idiot...
