[QUOTE="Ryushin, post: 6016096, member: 38551"] I've been trying to figure out what horsepower difference I'll see running a ported Eaton or Whipple/KB at 8-10 pounds of boost. I've been doing a lot of searching and haven't come across any definite answers. The stock cobra with just a CAI and a ported Eaton is [URL="http://www.websitetoolbox.com/tool/post/dynobob/vpost?id=1683153"]here[/URL]. So between a CAI and a Stage IV ported Eaton produced an extra 48 hp. I don't know what a Whipple/KB would have done at the same boost. I haven't found any write ups of anyone running that low of a boost level on a twin screw. I also found this article on some [URL="http://www.hiperformancestore.com/superchargerkit.htm"]myths of forced induction[/URL]. Scroll down about half way for the article for the Myths part. According to article, the Eaton is a very good supercharger. So I don't know the answer to this. Does anyone have any information on the efficiency of a Ported Eaton (blower) versus Twin Screw (compressor) type of superchargers. I'm still on my quest to achieve 500 RWHP using stock boost. I might have to go with cams and such to do it. Still researching, still learning... :idea: [/QUOTE]
