Serpentine Auto Tensioner Swap With Supercharger?
1/28/2018 Update: Yes you can replace the Auto-Tensioner & Pulley with a Comptech NOVI1000 Supercharger in place.
My step-by-step guide is a few posts down.
Is it possible to swap the serpentine belt Pulley & Tensioner, so the whole assembly with the supercharger still installed?
COMPTECH Novi1000 to be specific.

I know of no way to leave the SC drive belt in place while changing the engine serpentine belt.
The way that I last did it
Put a large C clamp onto the SC drive pulley to hold the belt in place. Rotate the C clamp to the side that will give resistance and cushion it with a big towel. Remove the nut from the drive pulley. Remove the C clamp
Release the tension on the SC drive belt. Remove the belt.
Remove the serpentine belt from the engine.

Ah okay, thank you for the tip.
Now, what if I'm not looking to replace the belt, so I can loosen the tensioner and let the belt hang. But is it possible to pull out the motor Auto Tensioner with the pulley attached to it, and replace the whole unit with SC in place?
Is there enough space between the block and Comptech SC plate for tensioner bolts to come out, slide the unit out, place a new one in, put bolts back in, and throw the belt back on the new tensioner?

Well, I guess I'll answer my own question :P. The answer is YES you can.
1) Disconnect MAP, TPS and any other sensors. Move them out of the way.
2) Disconnect/move vacuum lines that are in the way.
3) Disconnecting the TB to IM coolant line will make your life easier but it’s not necessary.
a. Fluid will come out so make sure to have rags under the each end of the hose, otherwise you’ll spill coolant on the alternator, tensioner & serpentine belt. (No Bueno)
4) Take the serpentine belt off.
a. Place 14mm wrench on the Auto-Tensioner pulley bolt, push toward passenger side
i. With Supercharger you won’t have much space to slip the belt of off the tensioner pulley. Remove belt of off the alternator pulley first, and then you’ll have slack to calmly slide it of off the serpentine tensioner pulley.
5) Loosen the 6mm Hex & 12mm Bolt that are holding the Serpentine Auto-Tensioner in place
a. !!!The S2KI DIY said 7mm Hex & 14mm Bolt… My bolts were: 6mm Hex & 12mm Bolt
i. https://www.s2ki.com/forums/s2000-un...e-belt-769113/
6) Swap in the new Auto-Tensioner
7) Tighten the 6mm Hex & 12mm Bolt
8) Slip the belt on the Auto-Tensioner first, then loosen the tensioner and finally slip the belt onto the alternator
9) Reconnect all the sensors and vacuum lines
10) Reconnect the IM to TB coolant line if you took it off
11) Start the car and inspect
a. Is the belt tension mark still not where it’s supposed to be? Replace the belt. You can only do that when the SC belt is off too, so plan on doing both.
