EFI intake options

[hackers2r]

I have been looking to get rid of my open airbox in exchange for a set of hyperstacks or tpo beast intakes for my S2R.  However, I have yet to find any evidence/support that doing so achieves anything positive in terms of power.  In fact, I've been reading that it may lose power from doing so.  Are there any supporters of these products that can attest to greater performance than an opened airbox on an EFI bike?  The clean look of the stacks wins hands down but I'd also like some functionality out of it too.

i cant say much for bikes with the stacks since i havent ridden one with them long enough to give an opinoin about it (other than its obnoxiously loud for an everyday bike, but great if its a weekender). but i can say that going from airbox to pods without anything in between (like a vstack) noticeably kills your lowend power. I had Cycleworks pod filters on my bike without adding vstacks and i took them off after a weeks use. The airbox is specifically designed for our bikes and i think most experienced ducati techs will say there is no replacement for a stock airbox (they still use airboxes for motogp or WSBK so that should tell you something).



since most of your time is spent there, the bike feels like it losses power (when in reality, the power band just shifts). same thing is true from going open udder to stock system.
