Description
Billet Compressor Wheel Upgrade for 2003-2007 6.0L Ford Powerstroke
The Rotomaster A1370511N is a billet aluminum upgrade for the Garrett GT3788VA turbocharger. It replaces the heavy factory cast wheel to provide faster spooling, increased durability, and higher boost efficiency.
Specifications:
Inducer: 56.8 mm | Exducer: 82.0 mm
Pattern: 6+6 Dual-Plane (6 Primary + 6 Splitter Blades)
Material: Lightweight Forged Billet Aluminum
Fitment: Direct Bolt-on Replacement
The 6+6 staggered design optimizes airflow by using six primary blades to maximize intake volume and prevent air crowding common with high blade count wheels. The six secondary splitter blades provide the surface area necessary for high pressure compression, creating a broader efficiency map that ensures consistent power from low end torque to high RPM peaks. This dual layer geometry eliminates compressor surge during heavy towing while also reducing rotational mass to allow faster spool-up and improved induction efficiency which results in a more complete combustion and lower EGT’s across all load ranges.
