Because the ones that people are talking about that cost a couple thousand are actual serpentine superchargers. In this thread we are specifically discussing the validation of effectively functioning intake "forced-air" superchargers.

 

Alright well fck that...having the hardest time uploading the scanned image of the dyno'd results so I'll break down the finds:

These are all "to the wheel" results
1st run, with nothing on, stock: 235.1hp
2nd run, Stage 2 chip, also purchased at performancechiptuning.com:231.3hp
3rd run, Stage 2 + Intake supercharger: 227.0hp
4th run, Stage 2 + Intake supercharger: 232.6hp

So unless someone else can help me figure out why the hell i can't get the dyno image results to load thats it....

 

I couldn't figure it out either. The only way I was able to make it work was opening the file with Windows via Paralles and using Internet Explorer.
