Atomic Race Spec Steel Oil Pump – Ford Barra DOHC | Medium Pressure (~80psi) | VCT Compatible | Blueprinted & Bench-Tested
Description:
High-performance Ford Barra engines demand a high-performance oil pump — and Atomic has engineered the answer. The Atomic Race Spec Steel Oil Pump (Medium Pressure variant) is a fully prepped, blueprint-matched, and bench-tested unit designed to deliver stable, reliable oil pressure in performance builds retaining Variable Cam Timing (VCT).
This pump features precision-cut billet steel gears, a gas-nitrided CRMO backing plate, and a cast steel housing that expands significantly less than OEM or billet aluminium bodies — keeping oil pressure consistent across the temperature range, even under race conditions.
With a target relief pressure of ~80psi, this pump provides enough pressure and volume to support high-horsepower, VCT-equipped builds without triggering ECU faults or causing cam control issues — a known issue with over-pressured systems.
✅ Key Features:
✅ Suits Ford Barra DOHC 4.0L 6-cylinder engines
✅ Medium Pressure (~80psi) – ideal for VCT-equipped setups
✅ Assembled from cast steel pump body – reduced thermal expansion vs aluminium
✅ Fitted with CNC billet steel oil pump gears – replaces weak powdered metal OE gears
✅ Includes gas-nitrided CRMO backing plate for improved wear resistance
✅ Fully blueprinted, assembled, and bench-tested in-house
✅ Every pump tested for pressure at operating temp (~90°C) over 1 hour
✅ Engineered and tested for 7500+ RPM operation
🛠️ Why This Pump Is Built for Performance:
✔️ OE gear failures are common under torsional crank load — solved with billet steel
✔️ Gerotor-style pumps (like Barra, 2JZ, and Nissan) see extreme loads at high RPM
✔️ Manual gearboxes increase torsional shock — our gears are designed to withstand it
✔️ Standard aluminium housings can split under hydraulic pressure — ours won’t
✔️ Used in Atomic engine builds from 600hp street cars to 1500hp race monsters
✔️ Pressure tuning during in-house testing ensures each pump suits its specific application
⚙️ Spring Selection & Tuning Advice:
-
🟢 Medium Pressure (~80psi) – Recommended for VCT-equipped engines (prevents cam control errors and VCT lockout)
-
🔴 High Pressure (>100psi) – Recommended for vernier gear or VCT-delete engines with fixed cam timing
