What is the advantage of a ball-bearing turbocharger?

Ball-bearing turbochargers, like this Turbosmart TS-1, generally offer quicker spool-up and improved throttle response compared to traditional journal bearing turbos. The reduced friction from the ball bearings allows the turbo to spin up faster under load.

What does the '1.24 AR' on the turbine housing mean?

The '1.24 A/R' refers to the Area/Radius ratio of the turbine housing. A larger A/R like 1.24 typically allows for better exhaust flow at higher engine speeds, helping the turbocharger to make more power in the mid to upper RPM range, though it might slightly delay initial boost response compared to a smaller A/R.

What does 'externally wastegated' mean for this turbo?

An externally wastegated turbocharger uses a separate wastegate actuator that is mounted on the exhaust manifold or a dedicated port on the turbine housing. This setup provides more precise control over boost pressure compared to internal wastegates, helping to prevent over-boosting and allowing for more consistent power delivery.

Product Details

Turbosmart is well-known for making robust performance parts for a wide range of vehicles. This TS-1 turbocharger is a prime example of their commitment to power and reliability. It features a T4 exhaust housing with a 1.24 A/R ratio, which is designed to help your engine breathe better and make more power, especially in the mid to upper RPM range. This setup is externally wastegated, giving you more control over boost pressure and helping to prevent over-boosting.

The compressor side uses a 76mm inducer and a 102mm exducer, with a 52 trim. This combination is built to handle significant airflow, making it a solid choice for builds aiming for substantial horsepower gains. The turbine wheel is a 70mm exducer with a 61mm inducer, made from Inconel for durability under high temperatures. The entire assembly is built on a ball-bearing core, which offers quicker spool-up and improved response compared to journal bearing turbos. This means you'll feel the boost come on sooner and more consistently.

This turbocharger is designed for custom applications where precise control and high-volume airflow are critical. It's important to note that this turbocharger is not CARB approved and cannot be shipped to California. Proper tuning and supporting modifications will be necessary to get the most out of this unit and ensure your engine operates safely.
