As a heavy mechanic, I break down every major change Cummins made — from the new cast-iron engine block and side-drafting intake to the redesigned CP8 high-pressure fuel pump pushing an incredible 39,000 PSI. We’ll go through the new cooling system, improved water jackets, broader torque curve, and emissions updates that help this Cummins meet stricter 2027 EPA standards. I’ll also compare it directly to the 2024 HO Cummins so you can see what’s actually different in the rotating assembly, fuel system, and tuning. This isn’t just a surface-level review — it’s a full mechanical breakdown of how Cummins re-engineered one of the most trusted diesel platforms on the road. 00:00 - Intro 00:56 - Walk Around/ Power Specs 03:47 - Reasoning for Engine Update 04:09 - Engine Design 05:30 - New Cast Iron Engine Block 07:18 - New Helical Timing Gears 08:49 - Upgraded Intake Manifold 10:37 - New Glow Plugs 11:35 - New Bosch CP8 Fuel System 17:15 - New Oil Filter 17:49 - New Turbo 19:15 - Upgraded Emission Systems :) 24:01 - New Driveline 24:36 - Test Drive
