With adam.nonis at the dyno this morning, here's the punchline.
-N52 DISA intake clearly makes the most low-end torque but then peters-out (red) No surprise there.
-N54 suffers on the bottom and only shines because it can sustain power at the very top (green)
-The M50-style intake did pretty good on the bottom end but not as well as DISA in a narrow range, but broadly outperformed both DISA and N54 intakes from 3800 all the way to 7200. (blue) Further, it made more peak power at a lower rpm and just feels more responsive driving.
272hp on this dyno is about 258+/- on a Dynojet.
