SPOOLOGIC Stock Plus Low Pressure Turbocharger

The SPOOLOGIC SL-100-033 Stock Plus Low-Pressure Turbocharger is a brand-new, direct-fit performance upgrade for the large rear-mounted low-pressure 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-220-022 64.5/88/96 mm 7+7 billet compressor wheel with the factory-size SL-240-007 79.6/73.2 mm 10-blade turbine shaft for increased compressor airflow while retaining direct-fit installation in the factory compound system.

• 7+7 billet compressor wheel
• 10-blade turbine shaft
• Factory-style turbine housing
• Journal bearings, 360-degree thrust bearing, and step-gap seals
• High-speed VSR balancing

What's Included

• 1 SPOOLOGIC Low-Pressure Turbocharger — SL-100-033

Low-pressure turbo only. High-pressure turbo sold separately.

Installation gaskets are not included. SPOOLOGIC Turbo Installation Gasket Kit — SL-310-013 is sold separately.

Fitment

• 2008-2010 Ford F-250 F-350 F-450 F-550 6.4L Powerstroke

Tuning and Supporting Modifications

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

Power Support

Can deliver approximately 20–30 additional rear-wheel horsepower and 10–15 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.
