What does the 1.21 A/R ratio mean for my turbo?

The A/R ratio, or Area/Radius, affects how your turbocharger performs. A 1.21 A/R generally helps to reduce exhaust backpressure at higher RPMs, which can lead to improved top-end power and efficiency for your turbo setup.

What material is this turbine housing made from?

This turbine housing is made from stainless steel. This material is chosen for its strong resistance to the extreme heat and corrosive exhaust gases common in forced induction applications.

Can this part be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

TiAL Sport is well-known for making robust turbocharger components, and this F3V turbine housing is a prime example of their work. This particular housing is designed for GT30XX series turbos and features a 1.21 A/R ratio, which helps to optimize exhaust flow for improved turbo spool and power delivery in certain applications.

Constructed from stainless steel, this housing offers solid resistance to the high temperatures and corrosive exhaust gases found in forced induction systems. The 1.21 A/R (Area/Radius) ratio is a key spec that influences how quickly the turbocharger spins up and how much boost it can efficiently produce. A larger A/R like this one generally favors top-end power and can help reduce backpressure at higher RPMs, making it a good choice for builds focused on maximizing horsepower.

Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer documentation for specific installation details and compatibility with your turbocharger setup.
