Supercharger service advice
I have the changed the supercharger oil and gasket. Before I start putting the car back together is there any jobs I should do?
Here is what I have done while the supercharger is off and the car is in front end service mode
1) replaced the water pump and O rings
2) replaced the upper and lower radiator hoses
3) replaced the MAP sensor hose
4) replaced the green gasket

I’d replace the serpentine belt, belt tensioner and idler pulley, if that’s never been done. While you’ve got the cooling system empty, I might recommend replacing the coolant overflow tank with a metal one since the plastic ones fail regularly. I did the dipstick o-ring at the time I did my s/c. And be sure to check all the vacuum tubes. I’d do a smoke test while I still had the s/c off, just because you’ll have somewhat better access to some of the tubes. And if you had any oil on the block, clean it off so you can more easily spot fresh leaks.

While I had my car in front end service mode I went ahead and also cleaned the throttle body and bypass valve. These can be done with the car back together, but it is a bit easier with the front end off. I also changed the throttle body gasket and the circular seal between the bypass valve and the driver's side intercooler horn (mine was flat and causing a vacuum leak).
