I have similar modified intake manifold like you do but it has really long ports, do you think they are suitable for 5000+ rpm? I'm thinking of making them shorter like many others have done, I believe it's because long ports are better for low rpm. I would like to know what you think about shortening intake ports. One more thing, have you compared turbo and na cam's duration and timing, is higher lift only difference or do they have different timing also?
