Pavel's Racing Engines is pleased to offer this high-quality billet compressor wheel fit for the Garrett GT3071R turbo. This compressor wheel compatible with authentic Garrett ball bearing turbos as well as aftermarket journal bearing versions. This is same 11 blade design as the Garrett GTX3071R turbocharger uses.
Inducer:53.1mm
Exducer: 71mm
Extended tip: 74mm
Blade geometry: 11 blade (GTX style)
Standard features and advantage:
- 11 blade design:Conventional cast aluminum Garrett compressor wheel uses a 6 tall and 6 short blade geometry. Garrett has shown substantial air flow gains, as evident by compressor map comparisons, of this 11 blade compressor wheel over the previous design.
- Extended tip design: Conventional compressor wheel tips end perpendicular to the exducer diameter. Extended tip technology originally developed as "cheater" compressor wheels for racing use. Standard exducer diameter is 71mm, while extended tip compressor wheels had 74mm exducer diameter. This of it like a larger area of an airplane wing allowing for increased lift. The larger surface area allows for increased flow volume at same turbo speed.
- Slim blade design: Performance feature designed to increase air flow. Slim blades have a smaller cross-section allowing more area between blades for air.Flow is increased at same turbo speed.Thinner blades also weigh less for reduced moment of inertia and faster spool.
- Slim hub design: Another feature designed to increase air flow. Slim hub increased air volume with each rotation. Flow is increased at same turbo speed. Smaller cross-section hub weighs less for areduced moment of inertia and faster spool.
- Material selection: Conventional compressor wheels made by casting aluminum alloy. PRE compressor wheels machined from billet aluminum alloy block. Billet blocks are forged. This compacting of molecules increases material density and strength. Increased strength of billet material allows for reduced blade and hub cross-section and weight reduction without increasing internal stresses.
- Balancing: PRE compressor wheels are inspected and computer balanced to less than 0.5g-cm^2. This does not mean compressor wheel should be swapped as-is. Stack-up disbalance is always a factor and compressor wheel balancing should always be performed by a professional using entire rotating assembly.
- Weight: PRE billet compressor wheel is 8.2% lighter than the cast aluminum version. This translates to improved spool and response from reduced moment of inertia.
