Big Turbo Upgrade AMG V12 Would Not Make Power Until We Built A Mercedes S65 m279 m275 Air Flow Mod

This is Part 4 of our Mercedes S65 AMG V12 build, and the one where the car finally starts telling the truth. This W222 S65 runs the AMG V12 biturbo platform found across the M275 and M279 engine family used in cars like the S65, CL65, SL65, and other late-model V12 AMGs. After installing hybrid turbos, upgraded cooling, aftermarket wastegates, and a full custom exhaust, the car still refused to make the power it should have. What we found was not a tuning issue, not bad parts, and not a simple fix. It was a combination of airflow restriction, wastegate control limits, and OEM components that were never designed to see sustained mid-20 PSI boost on this rare V12 ECU platform. In this episode, we address the real bottlenecks holding back power on the AMG V12 biturbo setup. We step back on wastegate spring rates so the ECU can actually control boost instead of fighting it, install larger Speed Driven intercooler cores that are no longer in production, and redesign the factory air intake system that was severely restricting airflow on this M279-powered S65. The result is controllable boost, lower intake air temperatures, and a major jump in wheel horsepower, while exposing the compromises built into modern Mercedes V12 AMG platforms when pushed beyond stock power levels. /TIMESTAMPS/ 00:00 | INTRO 01:32 | HISTORY 06:40 | BOOST UPDATE 09:46 | WASTE GATE SPRINGS 13:37 | INTERCOOLERS 20:57 | INTAKE FAB 26:57 | DYNO 39:19 | OUTRO If you want to see how we got here, watch the earlier parts of the series documenting this S65 AMG build from the start.
