[QUOTE="96CynRnr, post: 586545, member: 6354"] Ok so here are the numbers... what I had done was a Port and Polish on a CNC machine to clean up and smooth the airflow. And they drilled the secondary intakes so they will always flow a little bit. The changes are as follows... the airflow is what we are measured in CFM ... I will put stock first and then after Ported and Polished. Get ready for nerdy stuff : :read: 77 CFM @ 0.1 inch of valve lift to 96 CFM @ 0.1 inch of valve lift 129 CFM @ 0.2 inch of valve lift to 170 CFM @ 0.2 inch of valve lift 169 CFM @ 0.3 inch of valve lift to 228 CFM @ 0.3 inch of valve lift 195 CFM @ 0.4 inch of valve lift to 256 CFM @ 0.4 inch of valve lift 206 CFM @ 0.5 inch of valve lift to 273 CFM @ 0.5 inch of valve lift So as you can see... the valve flow increases by: 24% at .1 inch 32% at .2 inch 34% at .3 inch 31% at .4 inch 32% at .5 inch or an average of 31%-32%... seems pretty respectable to me! I realize it's expensive... but from a seat of the pants (no dyno numbers yes) it's really nice... pulls ALOT harder at the upper RPMS and I didn't really think that was possible. As you can see the real benefit is in the highest valve lift range... a increase of almost 67 CFM! :lol: /darin :beer: [/QUOTE]
