    Default Supra Head Flow (5M,7M,1JZ,2JZGE,2JZGTE)

    Stock heads:


    Note -- I need good data on the 1JZ. The current graph is an approximation based on the idea that the 1JZ flows 90% of the 2JZGTE intake, and 88% of the 2JZGTE exhaust. I got this data from a post by Erin Carpenter on Supraforums where he tested a stock 1JZ intake port at 215cfm at .4" lift and 133cfm for the exhaust (he tested a 2JZGTE at 238cfm intake and 154cfm exhaust). Its quite possible that the 1JZ flows as well as the 2JZ up to a certain lift, and then stalls earlier (more like the 7m). The rest of the engines are about as accurate as one could expect -- averaging data from 3-8 people/engine.
