2004 GTO Supercharged/Intercooled 575HP!
This is my 2004 GTO for sale. I bought it almost brand new with 400 miles on it in Atlanta, GA. It has been in Savannah, GA the rest of the time. Currently it just passed 12K miles. I installed the supercharger at 3300 miles so there is less then 9K miles on the supercharger.
Here is a list of all modifications that were professionally installed by me, the owner. This GTO has been completely trouble free since I acquired it in May 2005. I am selling to buy a truck, I can't afford to keep the GTO and buy a truck so the GTO has to go.
Custom tuning was required for best performance. This was done in Savannah at a chassis dyno and final numbers were 501 rwhp with 445 rwtq. The horsepower number is taken from the rear wheel and is approximately equal to 575 horsepower at the engine. Attached below are the graphs showing the excellent torque curve.
A video while the GTO was on the dyno is available so you can hear the sound of the Kooks headers and Borla exhaust. You can download it here, right click, save target as. http://www.blackgto.com/video/John5-16-06.wmv
