After the last dyno session I now know that I need to make a change. Off with the Forcewinder, but I can't decide what to replace it with. Either the Roland Sands Venturi, or the kurakyn Hi-five. Any suggestions or experiences? I have read alot about the Hi-five and the performance capabilities. But I can't find much about the RSD Venturi.

 

Those filters don't look like they would flow more air than a forcewinder. A heavy breather might.. I've never seen a comparison on airflow between different filters.
