Boost Tee by Turbosmart

Turbosmart’s All-New Boost Tee is a facelift on the tried and tested Boost Tee you’ve come to love. Now featuring a 33% smaller and more ergonomic design, the All-New Boost Tee incorporates the same functionality that makes it a crowd favourite, including our unique Gate Feature for maximum boost response and anti-tamper locking feature and easy use.

The Boost Tee is a pneumatic bleed valve that allows an increase in boost on turbocharger systems where boost-based actuators are used and are suitable for use on both internal and external wastegate systems. An increase in boost over and above the base spring pressure can be achieved by manipulating the reference signal to an internal wastegate actuator or external wastegate. It is common to reach 100 – 200% increases in boost over the base spring pressure.

Best Value Upgrade

Using our proven detent system, the controller can increase boost in defined steps, and the locking mechanism allows the boost level to be set & secure from tampering.

Manufactured in Australia from High-Grade Brass and Billet Aluminum, the All-New Boost Tee by Turbosmart is a simple, elegant and robust solution that can be relied on for simple boost control & maximum response. No doubt, the All-New Boost Tee is the best value upgrade for your Turbocharged engine!

Boost Tee Features

  • Proven Detent System for simple & defined control
  • Unique Gate Feature for Maximum Boost Response

Frequently Asked Questions

Ensure you have an over-boost cut-out. This is a safety feature built into basically all factory, aftermarket & programmable ECU’s. Make sure it is set at a sensible & reasonable limit. Increasing the boost will put more load on your engine, and there are other tune-related factors you must always consider. IF in any doubt, speak with a professional tuner/calibrator.

Suppose your engine is turbocharged and uses a boost-based actuation, then yes. The All-New Boost Tee by Turbosmart will work on any Boost-Based Internal Wastegate Actuators and External Wastegates. It will not be suitable for VGT (Variable Geometry) Turbochargers, also known as VVT (Variable Vein) and VNT (Variable Nozzle) or Vacuum-Based Actuators.

The maximum boost you will be able to make will come down to other variables with your setup. Turbocharger efficiency must be respected and as such as you start to work a turbocharger harder and towards the limits of its efficiency, boost can be harder to achieve. With that said, on an otherwise efficient setup you can expect to be able to achieve 1-2 times the base mechanical spring pressure as fitted to your actuator or wastegate.

Gate-Feature is a technology built into all Turbosmart Boost Controllers which promotes boost response and is a process of manipulating the reference signal for maximum gains. There is no other way to achieve such aggressive boost curves than the Turbosmart Gate Feature.

Yes! If maximum boost response is not what you’re after you can disable this feature. Refer to the technical drawings & instructions as you will need to remove the ball and spring on the inlet side of the All New Boost Tee.

Yes! This Arrow indicates the direction of flow of the reference signal (compressed air from the charge pipe or turbocharger) to the actuator. The Arrow direct must be respected & fitting the All-New Boost Tee backwards will result in boost control problems and instability.

No! The All-New Boost Tee by Turbosmart is designed to increase the boost pressure above the base spring pressure. If you are looking to decrease boost pressure, you may need to change the spring within your actuator or external wastegate.

No! One-click either up or down on the All-New Boost Tee is not one psi. The actual change per click will be specific to your vehicle and your setup. The efficiency of every setup is different, and as such, the changes are not identical from vehicle to vehicle. We recommend making small changes at first to understand your setup first and foremost.

Here is a handy self-help guide to helping you with your Turbosmart install and answers to some of the most frequently asked questions we get here. Turbosmart recommends that you get your products fitted and tuned by a qualified technician. If you choose to fit and set the product up yourself, ensure you have all the necessary tools and technical knowledge required to perform this task.
