Thanks for the info. I'll look into your suggestions on porting it. Best I can do for a flow test is to spray pressurized water through the ports and see how the water flows through it.
Regarding your earlier question as to whether to use it or the 115 intake, I agree with your assessment. Good mid-range to high end with this intake. Better than stock for low end, but not better then the 115. But I would love to see the actual bench flow numbers on this intake. I would guess the 115 would have the better combined all RPM range flow because of the long runners and gradual bends. The BSA intake has an almost 90 degree bend into the cylinder head, which I think would hinder flow. I do believe it is still far better then the stock intake manifold.
I don't think with the BSA exhaust manifold, the turbo would clear the 115 intake. Then again, I could be wrong. In the end between the two, I think I'm eventually will go with this BSA intake.
