Does anyone know if it is possible to put a 3.8 supercharger on a 2.8 engine? And if it is then how difficult would it be?

ANYTHING is "possible" with enough money and the willingness to go about it. The intake manifold would have to be "fabricated", as no one makes a blower intake for the 60 degree V6. The electronics may be a bit of a challenge, as well, but a computer "guru" should be able to work that one out. Some changes to the mounting or the body may be required to get the belt-drive in there. Find the best fabricator in your area and ask!

I've seen several converted to the entire 3800 S/C engine combo, and they're ANIMALS! One I know of goes in the high 11s in complete "street form" and the man is a bit afraid of it,. so it's probably quicker, yet. It uses a manual 5-speed from a later Baretta.

FWIW
