We have a 2004 Grand Prix GTP and I was wondering what is the best way to make it have more horsepower.

Buy performance parts from http://www.zzperformance.com and check out the forum at clubgp.com - lots of knowledgeable people. We even have a guy with a Grand Prix that's running a 9.01 second quarter mile.

Most GTP's have a factory supercharger on a 3.8 V6. The engine already has a lower compression ratio than the naturally aspirated one, so it opens a few doors for you.
A smaller pulley on the factory s/c or a bigger s/c would be a reasonably easy and economical way to get more boost.
Also an aftermarket chip will assist in advancing the ignition timing, changing the transmission shift points and changing the air/fuel mixture.

noX will give the biggest bang for the buck. It depends on how much more HP you are looking for. You could upgrade the exhaust and a cold air intake for a little extra HP.
