Head Flow Comparison Table I have compiled some head flow data over the past couple days and entered them in a spread sheet. Most of the data is Vendor posted and a few were independent tests. I don't remember which were independent.
I did my best to capture all the data but it was difficult to get all the info about each head and the test. So if you have some data to add or able to fill in my blanks feel free to send me a pm or just post up the info.
jrp - If you see this can you send me the link to your tests that you did? I coudn't find it for some reason.

If you used Excell or similar to create the spreadsheet you can plot the different values on a graph. flow vs lift one for intake and one for exhaust. A good tool for calculating under the curve flow. .X50" nos. would be usefull in tightening up the curves.

here's a table of flow from circa ~03 that someone compiled back then. my head flow and PP head flow test data can be found in the FAQ linked in my sig. at any rate taken as a whole for comparitive purposes this data is worthless. and what you see isnt always what you get, i've been victim of the red pill twice, and its not a fun thing to swallow
