Hey, I was browsing through the internet looking for information regarding exhaust system tuning (mainly to play off of Rotarygod's idea about porting the exhaust ports of the renesis engine because I think the exhaust system of the engine would be detuned by this unless a custom header was developed). Anyways I came across the World Intellectual Property Organization and holy *****, some amazing tech articles, thought I'd post up a few (these aren't for the technically faint of heart ) Lots of good stuff in there
