What is the maximum amount of airflow in lb/min or lb/hr, normally aspirated, that a B16 head can support? I know you can boost a B series to at least 550 hp, from what i've seen/heard from other peoples cars on this forum. I wonder because I was talking with some friends, and the airflow=HP subject came around. I asked in the technical forum, but I must smell bad or something cause nobody could even guess at an answer.

Based on airflow only, you can use this formula:
Keep in mind that you have to account for several additional 'real world' factors that effect observed output.

cylinder head CFM @ 28" / 1.05 x .272 x # of cylinders = expected 100% V.E. HP

Example with ported LS1 V8 (because I don't know what a stock B series flows):

305/1.05 = 290.4761 x .272 = 79.0095 x 8 = 632 HP @ 100% VE

 

Sweet. That's what i was hoping for.
