SPOOLOGIC Stock Plus Low Pressure Turbocharger

The SPOOLOGIC Stock Plus V2S Low-Pressure Turbocharger SL-100-033 is a performance upgrade for 2008-2010 Ford F-250 F-350 F-450 F-550 trucks with the 6.4L Powerstroke. Its billet compressor wheel adds airflow capacity and can deliver approximately 10-15 additional rear-wheel horsepower and 5-10 lb-ft of torque over a healthy factory-size low-pressure turbo when paired with a healthy high-pressure turbo and the proper engine combination.

Features

• Brand new, no core charge
• Direct-fit low-pressure installation in the factory compound system
• 7+7 billet compressor wheel
• 10-blade turbine shaft
• Upgraded journal bearings, 360° thrust bearing, and step-gap seal rings
• High-speed VSR balanced

Tuning and Supporting Modifications

Tuning is optional and is not required to use this Stock Plus turbocharger.

Power Support

Can deliver approximately 10-15 additional rear-wheel horsepower and 5-10 lb-ft of torque compared with a healthy factory-size low-pressure turbocharger when the SL-100-033 is paired with a healthy high-pressure turbocharger and the proper overall engine combination. Actual results vary with vehicle condition, fueling, calibration, supporting components, and test conditions.

Compound Turbo System

The factory compound system uses two turbochargers in sequence. Intake air passes through the larger low-pressure compressor, then the smaller high-pressure compressor before reaching the intercooler. Exhaust drives the high-pressure VGT turbine first, then the low-pressure turbine.

The matching Stock Plus high-pressure turbo is SL-100-034. For a cast-compressor low-pressure replacement, compare the Stock SL-100-031. 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.
