SPOOLOGIC Stock Plus High Pressure Turbocharger

The SPOOLOGIC Stock Plus V2S High-Pressure Turbocharger SL-100-034 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 upgrades the high-pressure side and can deliver approximately 10-15 additional rear-wheel horsepower and 5-10 lb-ft of torque over a healthy factory-size high-pressure turbo when paired with a healthy low-pressure turbo and the proper engine combination.

Features

• Brand new, no core charge
• Direct-fit high-pressure installation in the factory compound system
• 7+7 billet compressor wheel
• 11-blade turbine shaft
• Upgraded journal bearings, 360° thrust bearing, and step-gap seal rings
• New VGT unison ring and vanes
• 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 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.

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 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.
