The SPOOLOGIC SL-100-034 Stock Plus High-Pressure Turbocharger is a brand-new, direct-fit performance upgrade for the small front-mounted high-pressure variable-geometry turbocharger in the V2S compound system used on 2008–2010 Ford F-250 F-350 F-450 F-550 Super Duty trucks equipped with the 6.4L Powerstroke. It combines the SL-220-023 51.8/74.1/79.7 mm 7+7 billet compressor wheel with the factory-size SL-240-008 69.9/62.7 mm 11-blade VGT turbine shaft, a new unison ring, and new vanes. The electronic actuator is not included.

⚠️ Tuning Information

The SL-100-034 runs correctly with the factory engine calibration, and custom tuning is not required. A properly matched calibration is recommended to obtain the maximum benefit from the upgraded billet compressor wheel. SPOOLOGIC does not supply, write, sell, or assist with custom tuning.

Verified Performance Gain

Verified results show approximately 20–30 additional rear-wheel horsepower and 10–15 lb-ft of torque compared with a healthy factory-size high-pressure turbocharger when the SL-100-034 is paired with a healthy low-pressure turbocharger and the proper overall engine combination. Actual results vary with vehicle condition, fueling, calibration, supporting components, and test conditions.

⚠️ Electronic Actuator - Not Included

The SL-100-034 does not include a new electronic actuator. The customer may reuse a serviceable original actuator or purchase a new replacement actuator separately. A new unison ring and vane assembly is installed in the turbocharger.

How the 6.4L V2S Compound Turbo System Works

On the compressor side, filtered intake air first enters the larger low-pressure turbocharger. The partially compressed air then enters the smaller high-pressure turbocharger, where it is compressed further before flowing through the charge-air cooler and into the engine. Exhaust first drives the high-pressure variable-geometry turbine and then flows through the low-pressure turbine before exiting through the exhaust system.

SL-220-023 51.8/74.1/79.7 mm 7+7 Billet Compressor Wheel

The five-axis CNC-machined billet aluminum compressor wheel retains factory-size 51.8 mm inducer and 74.1 mm base-exducer dimensions while adding a 79.7 mm extended-tip diameter for increased airflow capacity.

• Inducer Diameter: 51.8 mm
• Base Exducer Diameter: 74.1 mm
• Extended-Tip Diameter: 79.7 mm
• Blade Design: 7+7 — seven full-length blades and seven splitter blades
• Material: Billet aluminum

SL-240-008 69.9/62.7 mm 11-Blade VGT Turbine Shaft

The billet compressor is matched to the factory-size 11-blade variable-geometry turbine shaft, new unison ring, and new vanes.

• Turbine Inducer: 69.9 mm
• Turbine Exducer: 62.7 mm
• Blade Count: 11
• Configuration: Variable geometry

Upgraded Internals — Standard

• Extreme-duty journal bearings
• 360-degree thrust bearing
• Step-gap seal rings
• High-speed VSR balancing

What's Included

• 1 SPOOLOGIC Stock Plus High-Pressure Turbocharger — SL-100-034, Brand New, High-Speed VSR Balanced

Electronic actuator is not included.

Installation gaskets are not included.

Fitment

• 2008–2010 Ford F-250 F-350 F-450 F-550 Super Duty — 6.4L Powerstroke

Turbo Applications

• Stock Plus upgrade for the small front-mounted high-pressure VGT turbocharger
• High-pressure B2V stage of the factory V2S compound turbo system
• Designed to operate with a healthy factory or SPOOLOGIC low-pressure turbocharger

The matching Stock Plus low-pressure turbo is SL-100-033. For a cast-compressor high-pressure replacement, compare the Stock SL-100-032. To replace both stages with ceramic-coated turbine housings and exterior center sections plus a full installation gasket kit, see the Stock Plus compound set SL-100-036.

1-Year Limited Warranty

Every SPOOLOGIC turbocharger is covered by a 1-Year Limited Warranty against defects in materials and workmanship from the date of purchase. Warranty coverage requires that the turbocharger first be returned to SPOOLOGIC for inspection. If SPOOLOGIC determines that the failure was caused by a defect in materials or workmanship, the turbocharger will be repaired or replaced at SPOOLOGIC’s discretion. The warranty does not cover damage caused by foreign-object debris, oil starvation, contaminated oil, restricted oil flow, extended oil-change intervals, over-boosting, over-fueling, improper tuning, improper installation, operation beyond the turbocharger’s intended range, or use outside the listed application. It also does not cover labor, shipping, towing, downtime, incidental expenses, cosmetic wear, coating discoloration, or normal heat-cycling marks.
