Well I already have a supercharged 3.8, so I guess it wouldn't benefit my car. In fact since I have a 07 model can't even da a performance tune. I only have a few basic mods because of that. Anyway it sounds like an interesting modification.
Yeah if you already have a supercharged car it's useless, but if you're car is N/A and you topswap it with the S/C topend you actually have more HP than the standard S/C engine because the N/A engines have higher compression.
