Engine Forced Induction Options?

The supercoupe blower comes in two flavors. The gen3 and gen4. Gen3 is anemic without modification. The gen4 came with coated rotors and is a much better design.

These will make the car a torque hound lots of power down low thru 5k but above that it will fall off. I heavily modded a gen3 for a 5.0 and made 386tq and 296hp on a dynojet.

In the "worth it" area this is was fully maxed out I could not possibly make any more boost I was spinning it at twice the rated bearing rpm.

A gen4 or 5 could make more, an mp90 would be the best option they are heavily modded from the manufacturer.

Assuming you have a 3.8l

Just search eBay they pop up often use the keywords supercoupe or m90
