SPOOLOGIC Stage 1 Performance Turbocharger

The SPOOLOGIC SL-100-008 is a brand-new, direct-fit Stage 1 GTP38 performance turbocharger for Late 1999–2003 Ford F-250 F-350 F-450 F-550 Super Duty trucks and 2000–2003 Ford Excursion models equipped with the 7.3L Powerstroke. The Stage 1 combines a 60/80/84 mm 5+5 billet compressor wheel, factory-style GTP38 turbine wheel, 1.0 A/R internally wastegated turbine housing, high-temperature ceramic coating on the turbine housing and center section, upgraded 30 PSI wastegate actuator, and Non-EBPV pedestal and outlet configuration. This combination is designed for tuned and moderately modified trucks that need more turbine-side capacity and a higher wastegate-control range than the Stock Plus configuration while retaining a direct-fit GTP38 installation. It is designed to support approximately 350–400 rear-wheel horsepower with proper tuning, fueling, and supporting modifications.

⚠️ Boost fooler required. Custom tuning is highly recommended. See tuning requirements below.

Tuning and Supporting Modifications

⚠️ Custom Tuning Highly Recommended: Custom tuning is highly recommended to match this Stage 1 turbocharger to the engine, intended use, and supporting components.

⚠️ Boost Fooler Required: Install the SPOOLOGIC Boost Fooler / OCR Regulator — SL-610-002 to address the factory boost-monitoring limit. A boost fooler does not replace the tuning guidance above.

Supporting Modifications: Upgrade components as needed to support your intended power level.

• Larger injectors and fuel-system upgrades may be needed to reach the listed power range.
• Adequate high-pressure oil supply for the selected HEUI injectors.
• Intake and intercooler upgrades may be needed to reach the listed power range.
• Sufficient exhaust flow and leak-free up-pipes.
• Boost and exhaust-gas-temperature monitoring during setup and loaded operation.

SPOOLOGIC does not provide custom tuning services. Customers are responsible for arranging application-appropriate tuning with a qualified tuning provider.

Power Support

Designed to support approximately 350–400 rear-wheel horsepower with proper tuning, fueling, and supporting modifications. This is total power-support capacity, not a promised horsepower increase. Actual output depends on engine condition, fuel delivery, calibration, and the complete vehicle combination.

Non-EBPV Configuration

The supplied SPOOLOGIC Non-EBPV pedestal and outlet plate replace the factory exhaust back-pressure valve components, removing the valve from the exhaust path. An EBPV terminator is included for the factory electrical connection.

Compressor Wheel

• Inducer Diameter: 60 mm
• Exducer Diameter: 80 mm
• Tip Diameter: 84 mm
• Blade Design: 5+5 — five full-length main blades and five splitter blades
• Compressor wheel material: 5-axis CNC-machined billet aluminum
• Design: Extended-tip performance compressor wheel

Turbine Shaft

• Turbine Wheel: Factory-style GTP38 configuration
• Turbine inducer: 76 mm
• Turbine exducer: 68 mm
• Turbine blade count: 10
• Turbine wheel material: High-nickel Inconel

Bearings, Seals, and Balancing

Updated bearings and seals in the SPOOLOGIC rebuild kit — SL-210-002 improve durability, sealing, and shaft operation:

• Extreme-duty journal bearings — Bronze alloy with updated oil grooves
• 360-degree thrust bearing — Increased bearing area for axial loads
• Step-gap seal rings — Improved sealing and oil control
• High-speed VSR balancing — Smooth, consistent operation

Wastegate Control

The turbine housing uses an internal wastegate with the upgraded 30 PSI actuator — SL-260-004.

• Turbine Housing: 1.0 A/R internally wastegated

Coatings and Finish Options

The turbine housing and center-section exterior are ceramic coated to help manage radiant heat and resist oxidation. Heat reduction varies with operating conditions. The finish options below apply only to the compressor housing.

• Raw: Bare aluminum with no coating
• Red: Red powder-coated exterior
• Black: Black powder-coated exterior

Every SPOOLOGIC turbocharger carries a one-year limited warranty against defects in materials and workmanship from the original purchase date. Coverage applies to the original purchaser with dated proof of purchase. Contact SPOOLOGIC for return authorization before shipping the turbocharger for inspection. If inspection confirms a covered defect, SPOOLOGIC will repair or replace the turbocharger at its discretion. Damage from foreign-object debris, oil starvation, contaminated or restricted oil flow, extended oil-change intervals, over-boosting, over-fueling, improper installation or tuning, operation beyond the intended range, or use outside the listed application is excluded, along with cosmetic wear, coating discoloration, and normal heat-cycling marks. Customers are responsible for shipping both to SPOOLOGIC and back, whether the claim is approved or denied. Labor, diagnostics, removal, reinstallation, towing, downtime, and other related expenses are not covered. See the SPOOLOGIC Warranty Policy for complete terms and claim procedures.
