I'm contemplating doing this in a couple of years instead of trading up to something else - Depends how my car holds together - I dont have any squeeks or rattles yet.
The way I see it, Ascent/Conquest models are lighter than the Sportivo (Less accessories/standard equipment, no body kit etc), adding a Supercharger will match the power and have a sh!t load more low end torque in a lighter car ...
Do the math... The proof is Grimlock and Influx's ongoing challenges
Plus I just like the thought of having a Supercharged badge on my cars flanks :)
