You are not far off, but the intake you designed is more for higher torque numbers & peak HP numbers will be low.
I did not say too much because I thought you were making an intake for a N/A engine (which would be good), but not so much for turbocharging.
Having peak/great cyl head flow numbers will return you with high HP numbers.
Having a cylinder head such as our stock 2 valve heads will not make as high HP numbers but will give some good torque numbers when turbo or supercharged.
Just as an example, my V-6 4.3 cyl head flows 150ish CFM @ 28 inches with a 1.94" intake valve, = pretty bad, the camshaft is as anemic also (all stock), so when I chassis dynoed it, it made a peak of 604 FT lbs of torque but only 396 peak HP, @ 24-25 PSI of boost. Track ET, 3600 LBS no driver, 12.0 @ only 108 MPH, that was when I dynoed @ 386 HP & 550 FT lbs, was running too lean at that time. Not the fastest by any means, but the engine is still 100% original stock untouched.
