Here is a table of the dyno runs made at Atlanta Chassis Dyno. Dyno numbers before 4000 RPM's were not placed on this graph as I didn't think that people would be interested. However, more people were interested than I thought so I will see if I can get this data to include it in my graph for a better picture of where gains were found.

The first set of hp and ft-lbs of torque numbers represent my setup with the stock catalytic converter, Place Racing Cold Air Intake, and Greddy cat-back exhaust.

The second set of hp and ft-lbs of torque numbers represent my setup with the Random Technology 3" catalytic converter, Place Racing Cold Air Intake, Greddy cat-back exhaust.

The third set of hp and ft-lbs of torque numbers will represent my setup with the Autogear supercharger with custom Cold Air Intake, modified AT valve body, transmission cooler, Cattman Performance y-pipe, Random Technology 3" catalytic converter, and Greddy cat-back exhaust.

The peak ft-lbs of torque and hp were realized inbetween the RPM's, so I decided to shorten the graph by using 100RPM increments instead of 50RPM increments.

The first setup resulted in 159.3 hp at 5250RPM and 164.7 ft-lbs of torque at 4750RPM . With the second setup we saw that our hp raised to 166.1 at 5200RPM and our ft-lbs of torque raised to 180.6 at 4450RPM and at the wheels. This results in a gain of 6.8 hp and 15.9ft-lbs of torque. I think that results are pretty impressive due to the fact that I was running in 93 degree conditions and still making lots of torque in the mid and high end.

No doubt the 2.5" cat might be a better choice for naturally aspirated cars. Almost 16ft-lbs of torque and 7hp at the wheels is nothing to be taken lightly though. Here is a table of the emissions test that I put the Random Technology cat through and it passed with flying colors.

Here is the latest emissions test results that I recently got from my automatic 96 SE with a supercharger, Cattman Performance y-pipe, Random Technology 3" cat, and Greddy cat-back exhaust.
