People that have been putting these plenums on their cars and doing dyno testing are seeing more like a 3-5 hp gain. I believe supercharged cars are actually seeing a slight loss. I don't know what to believe when I read Mythical Mustangs & Fake Fords anymore. There is a huge thread on corral.net about it.
