Stock runner checked in at 300cc's mine is 313cc. The flow over the short turn is twice the speed of the long turn. The air across the short turn on the hook wall and straight wall are almost even. There is a little more velocity on the hook wall side. There is definitely no flow separation on the short turn. I just don't have the velocity to take advantage of the shape. I can only push so much air through a 1.895" throat at 5"hg. Nothing much else I can do in there. I tried a bunch of stuff today. Depending on the bore I used to test the head on the results varied. I think I am pretty much done on the intake. Now time to work the exhaust a little more.
