What Makes DMS Cams Different?
Dyno-developed profiles — not catalog grinds from a third-party supplier
Optimized for VVT — works with the factory variable valve timing system
Street-friendly idle — maintains acceptable idle quality for daily driving
Matched to DMS tunes — our ECU calibrations are built around these exact profiles
Requirements
Upgraded valve springs recommended for engines exceeding 7,200 RPM
ECU recalibration required (Stage 2 tune)
Professional installation recommended
Designed, tested, and proven on our dyno. The heart of every DMS performance build.
Fitting & cam-timing instructions (DMS Stage 2 Duratec)
Valve clearances (cold): Intake 0.20–0.25 mm · Exhaust 0.25–0.32 mm — always use these, not the OEM values. Lift at TDC (timing section) is measured with clearance, not zero.
Before fitting:
Wash the cams in fresh water — especially the hollow cams — to remove any grinding-wheel residue.
Lubricate the cam lobes, bearings and tappet surface (not the perimeter) with proper cam assembly oil.
Piston-to-valve check: at full overlap with the piston at TDC, confirm at least 1.5 mm clearance before valve-to-piston contact.
Running in: start the engine and hold 1500–2000 rpm for 15 minutes — do not idle.
Important: do not use launch control — it damages valves, valve seats, tappets and cams.
