Comptech supercharger manual only have instructions on how to check and fill oil. Anyone know how to drain the existing supercharger oil?

Don't do like me, thinking that a turkey baster will work. You'll end up with more oil all over the engine than you want to admit to.
Instead, buy a hand-held vacuum pump at the car parts store. I think a name brand is Mighty Vac. It comes with its own reservoir and a variety of tubing sizes and lengths. Stick one end of the tubing down into the supercharger and pump away. It will fill the reservoir about 1-1/2 times, before the oil level is so low that no more oil can be sucked out of the supercharger.

good question. here's my approach:
first, i unscrew the dipstick and place the cap in a safe place. next, i use the nose pivot adapter, lift the rear of the car up a bit and, when i've got the momentum-thing, just invert the car and let the oil drain out of the plug :>) piece of cake unless it's *really* cold (the oil is slow to drain in those situations). i'll make sure i get some pics and post them the next time i do this.
serially, i'd ping comptech and ask their procedure: info@comptechusa.com
be well.

The procedure I described was given to me by the person that has installed more NSX Comptech superchargers than anybody else - Mark Basch.
Thanks Andy, I'll try your method instead of Hal's.
