I've done it it's not hard at all. If you can find and download the instructions on the installation of the ctsc you just reverse and then follow the steps where they show you how to install the belt.
 
The instructions say to put the belt in before the alternator. I've been wondering if that is really the easiest way when changing the belt: to remove the alternator?

(fyi I posted a link to the instructions here.)
 
Thanks for all the responses but still a bit confused. I don't want to start the job without knowing if I should remove the alternator or not. Is there some tension bolts that I can loosen and remove the belt? This bolt is on most cars and it's quite simple. I guess I can always try to loosen the alternator bolts enough to get the belt out without taking the alternator out or having it just dangle somewhere than removing it. Also, does anyone have more insight on how to tighten the belt after is installed?

Install Supercharger belt: Belt needs to be

installed prior to alternator installation.

·
Install Alternator: once the belt is in place the

alternator can be installed using the two bolts supplied

in the kit. Hook up the newly extended main

power wire to the alternator using 1 of the 6m

flange nuts from the stock manifold’s fuel rail hold

down hardware.

·
Tension the belt: using the long threaded bolt

on top of the idle plate turn it clockwise until you

have about a 1/2” gap between the lower part of

the tensioner and the main body. Once set use the

two allen bolts on the back to lock it in place.
 
The tensioner is right next to the alternator, between the alternator and the blower pulley. It is a bolt that pushes the tensioner pulley down and has a lock nut against the tensioner bracket. Importantly, the moving block of the tensioner (which the bolt pushes down on) has two bolts that tighten to the bracket. You must loosen these two bolts before adjusting the tension, and tighten them after that. They lock the tensioner in place.

So loosen the two large locking bolts, apply tension with the tensioner bolt, then tighten the two locking bolts. The 1/2" gap that the instructions refer to are about the moving block of the tensioner itself. It is split in two pieces with two spring-loaded pistons between them. As you apply tension, the two pieces start to compress; when that gap is about 1/2", you have applied the right tension and can then lock the tensioner block in place. Be sure to check it later if you put in a new belt because they seem to stretch at first.
