What is the advantage of a V-band connection?

V-band connections offer a more secure and leak-resistant seal compared to traditional bolted flanges. They also make installation and removal simpler and quicker, as they use a clamp mechanism rather than multiple bolts.

What does the 1.40 A/R ratio mean for performance?

A 1.40 A/R ratio is considered a larger housing size. This generally means it will allow the turbocharger to flow more exhaust gas at higher RPMs, helping to reduce backpressure and keep the turbo from choking. However, it may result in slightly slower initial spool-up compared to a smaller A/R housing.

What are the implications of this housing not being SFI certified?

SFI certification is a safety standard often required for racing applications. If your racing series or application mandates SFI certification for turbocharger components, this housing would not meet those requirements.

About this part

Product Details

Garrett is well-known for its high-performance turbochargers and components, and this GTX55 Turbine Housing is a prime example of their commitment to power and efficiency. This housing is designed for serious performance builds where precise airflow management is critical. It features a V-band inlet and outlet, which makes for a secure and easy-to-install connection compared to traditional flanged setups. The 1.40 A/R ratio is on the larger side, meaning it's intended for high-flow applications and larger engines where you need to keep exhaust backpressure down at higher RPMs.

Constructed from stainless steel, this housing offers solid durability and resistance to the extreme temperatures found in a turbocharger's exhaust stream. The short outlet design is often chosen to help tuck the exhaust piping closer to the chassis, which can be important for packaging in custom applications. It's important to note that this housing is not SFI certified, meaning it's not intended for use in applications where SFI certification is mandated by racing sanctioning bodies. Also, this part is not CARB approved and cannot be shipped to California.

When building a high-output forced induction system, the turbine housing plays a crucial role in how the turbocharger spools and performs across the RPM range. This Garrett housing, with its specific A/R and V-band connections, is a well-built component for those looking to maximize the potential of their turbo setup. Ensure you have the correct V-band clamps and mating flanges for installation, as these are typically sold separately.
