Turbosmart Turbine Housing (66mm) V-Band (Reverse Rotation) 1.07AR

This Turbosmart turbine housing features a 66mm V-band inlet and a 1.07 A/R ratio, specifically designed for reverse rotation applications. The V-band connection offers a secure and compact way to mount the housing, simplifying installation and maintenance compared to traditional flanged setups. Its cast iron construction is well-built to handle the high temperatures and pressures found in forced induction systems, ensuring reliable performance over time.

The 1.07 A/R (Area/Radius) ratio is a key specification that dictates exhaust gas flow into the turbine wheel. A larger A/R like this one generally promotes better high-RPM power delivery by allowing more exhaust gas to flow freely, reducing backpressure at higher engine speeds. This makes it a solid choice for builds focused on maximizing top-end power. The reverse rotation design is critical for twin-turbo setups where the turbochargers spin in opposite directions, requiring specific housing orientation to match the turbine wheel's direction of spin.

When considering a turbine housing upgrade, it's important to match the A/R ratio and inlet size to your specific turbocharger's turbine wheel and your engine's performance goals. This housing is intended for custom turbocharger builds or as a replacement for a damaged unit in a compatible system.
