What will work with the Eaton M90

[bluto2000gs]

The great debate in the world of the GM cars with the 3.8 supercharged engines.
Some say spray the mix using an adaptor plate between the SC and the intake manifold.
Others say go ahead and spray before the throttle body and the SC.
Which is ok to do?
Is one risky?

I am installing a single stage on my 2000 Regal before the blower. Will it cause problems?

I am about 300 HP and 360 Tq.
Thanks for any input.
