I asked the same thing it would be better and cheaper to go with nitrous.Anytime you Supercharge or turbo charge you need a machine shop skills to make custom parts for you.To be safe as connecting rods are weak in the m104,I was going to run 6 psi.Because a centrifugal charger is easier to mount,I would have no boost till 5000 rpm,so nothing at take off.
