Good discussion. I guess we'll see the real world results soon and will read for ourselves. I only wish Ford had built a V-8 (without having to resort to a supercharger) to compete with Dodge and GM. Now GM finds itself doing the same with the high dollar Vette ZR-1[&o] If you have to supercharge then your engineers have ran out of ideas. At Dodge they keep adding technology to a real good package. This is my opinion and everyones got one... but others from the muscle car era agree and superchargers are nice. But should be added by a tuner or the owner. Factory added supercharger is just too easy and lazy way to make horsepower. Any Car Corp. could do it, just says we have run out of ideas and our tech is stagnent. So compare, but remember that the Challenger is NA and makes its power the Muscle car way with CID and high flowing hemi heads I'll say that says it all.
