MM&FF did an article on SC's and they dyno'd all of them too, you should see if you could order the back issue. Blowers will create more power from being intercooled also, you also have to look at the placement of the blower too, some mount in different areas of the engine changing the distance of the air flow and temperature of it air traveling. Generally though, they should be making very close to the same amount of HP give or take 10.
