The TurboXS SRT-4 Boost Upgrade dramatically increases the performance of your Dodge. This selection of parts is essential for your high performance build up: High Performance Wastegate Actuator, a Type RFL blow-off valve plus adaptor kit, and the TurboXS SBC boost controller.

When turning up the boost, the factory wastage is inadequate at maintaining higher boost pressures due to a week actuator. TurboXS incorporates a high performance wastage actuator designed to handle the additional pressure all the way to redline.

Upgrading the wastage puts more pressure on the stock solenoid controlled bypass valve which looses as much as 5 pounds of boost pressure, over works the turbocharger, and causes higher intake temps, which results in a loss of horsepower. The TurboXS Type RFL blow-off valve kit is designed to handle the boost all the way to redline and lets everyone know you mean business! Dyno plots coming soon. On race fuel at about 18 psi the TurboXS SRT-4 went 13.6 @ 107.4 mph in the quarter mile (2.4 60ft on stock wheels and tires. What can I say, we're used to racing AWD WRXs ;).
