You may want to reconsider putting a supercharger on a naturally aspirated 3800 engine. The supercharged 3800 has a lot of different internal parts like pistons, values, rockers and such putting a supercharger on a base Grand Prix will cause severe internal damage. Not to mention voiding any warranty you may have.
That being said you should check out there can hook you up with anything 3800 related.
Straight up, go trade your base model for the GTP model. Your’re looking at so much work to put that supercharger in. The Grand Prix GTP’s are supercharged w/ 260 horses and 280 ft lbs. For the 07 Grand Prix’s, the GT model is the supercharged one. Regardless, you’re base v6 engine cannot handle that much power unless you’re forking over some major cash in huge upgrades. Personally, I don’t think it is worth it. You want some extra power on your base model . . . air intake, exhaust, k&n air filter. BTW - you’re looking at about $700 -$2000 for a supercharger. You can get ‘em anywhere from AutoZone, SummitRacing, eBay, AutoAnything.com , etc
Go to ebay and seach for a M90 supercharger, it’s simple.
