I know it's not the same comparison, but looking here at their dyno chart for the Cayman S IPD/RSS Plenum, there were gains everywhere, with ~24hp and ~19ft-lb torque peak...

I'm wondering though, how come with Pedro's splitter/plenum, he says 6-8ft-lb at lower rpms with not much gain for the higher rpm hp? The RSS plenum seems to get the gains from low to mid, and high rpms...

thoughts anyone?
the air flow diagram shown by Pedro shows deliberate/smooth routing of the air on the bottom side, the top side is not contoured due to the use of stock intake tubing. IPD replaces this with smooth Y design all around. it's logical that if the top surface is equally contoured, additional 2X gain may be realized.
Ratio of IPD to Pedro is roughly 2X, Pedro's mod affects only 1/2 of the pipe, IPD mods entire ID of the pipe.
