When you are pushing high levels of boost, every component in your induction system plays a critical role in how efficiently air reaches the engine. While turbine housings and compressor wheels often grab the spotlight, the compressor housing cover itself is the ultimate gatekeeper of charge-air velocity and thermal efficiency.
Recognising the need for maximum airflow in extreme performance and racing setups, Turbosmart has officially introduced the Pro Series for the C-Frame turbocharger lineup.
Designed to seamlessly fit the 6870, 7275, 7675, 7880, and 8280 C-Frame TS-1 and TS-2 turbochargers, these upgraded compressor covers represent a major leap forward in high-boost engineering.
WHAT MAKES THE PRO SERIES DIFFERENT?
The standard C-Frame compressor cover was engineered to deliver compact dimensions alongside high airflow output. However, when you push past traditional performance thresholds, smaller housing volumes can begin to restrict (choke) compressed air as it leaves the compressor wheel.
The C-Frame Pro Series Cover solves this issue by expanding the internal geometry of the housing. With an enlarged internal scroll (volute) and a redesigned 5” diffuser inlet section, the Pro Series cover gives high-velocity charge air the space it needs to efficiently convert dynamic air velocity into clean static boost pressure.
KEY BENEFITS: WHY UPGRADE TO THE PRO SERIES COVER?
Upgrading your C-Frame turbo with the Pro Series Compressor cover delivers several tangible advantages on the dyno and the track:
MAXIMUM TOP-END AIRFLOW & POWER POTENTIAL
The main reason to step up to a Pro Series cover is total flow capability. By relieving internal back pressure around the compressor wheel, air moves through the housing with significantly less restriction. This enlarged internal volume unlocks extra top-end horsepower without requiring a change in turbine size or engine speed.
LOWER INTAKE AIR TEMPERATURES (IATS)
When air is forced through a tight compressor scroll at high speed, friction and turbulence heat up the charge before it ever hits your intercooler. The optimised aerodynamic profile and larger volute of the Pro Series reduces air turbulence, keeping intake charge temperatures cooler.
NATIVE V-BAND FLANGE OUTLET
The Pro Series cover features a true 3.0-inch compressor outlet. This allows for a direct high-flow connection without needing step-up adapter hoses or reducer couplers that disrupt airflow. Turbosmart offers flange kits to suit 3.0”, 3.5” and 4.0” charge air systems.
REINFORCED C-FRAME HEAVY-DUTY CONSTRUCTION
Built to handle extreme racing conditions, the Pro Series casting retains Turbosmart’s heavy-duty C-frame structural design. Under continuous high-boost stress, lesser covers can flex or suffer housing distortion, the Pro Series keeps tolerances tight and efficiency high under continuous load.
IS THE PRO SERIES RIGHT FOR YOUR BUILD?
If you are running a street-driven setup at moderate boost levels where engine bay space is tight, the standard C-Frame cover remains an outstanding option.
However, if your build is focused on drag racing, time attack, or squeezing every last drop of top-end power, swapping to the Turbosmart C-Frame Pro Series is one of the most effective ways to lower charge temps, eliminate intake restrictions, and maximise your turbocharger’s true output potential.
ALREADY OWN A C-FRAME TURBO?
The great part about the Pro Series is that they are available as a complete turnkey unit or you can upgrade existing C-Frame turbos into a Pro Series unit. Pair this with one of our 3.0”, 3.5”, or 4.0” flange kits and you’re on your way to more peak horsepower!
