Big Bubba is available in two different styles, Bubba Sonic (Full time vent-to-atmosphere) and Big Bubba (Full time recirculating)
The Power Port is Turbosmart’s largest and highest flowing blow-off valve ever, resetting the flow benchmark set by our popular and highly regarded Race Port BOV. Designed to be as light as possible, to keep vehicle weight down. Its cutting edge dual-chamber design means it can be held open with the use of a solenoid to aid turbo response and control during staging to give the best possible launch. For high HP turbocharged or supercharged applications.
The Turbosmart BOV controller is an electronic device which controls the pressure signal to the BOV. It works by detecting a negative voltage change in throttle position. It then energises a solenoid to vent all of the air out of the BOV cap, causing a pressure differential between the piston of the BOV and the cap which will vent pressure from the intake system.
A wastegate is a valve which controls the flow of exhaust gas from an engine to the turbocharger. By controlling the flow of exhaust gas to the turbine of the turbocharger, the wastegate can control the boost pressure provided by the turbocharger to the engine. The wastegate needs to be correctly sized for the engine and turbocharger combination to give the end user adequate control on boost pressure.
There are two types of wastegates: external wastegates, and actuator driven internal wastegates.
An internal wastegate has the wastegate valve is built into the turbine housing. The wastegate valve is controlled by an actuator which consists of a spring and a sealed chamber. The sealed chamber of the actuator is connected to a pressure only source normally on the compressor cover of the turbocharger. Turbosmart internal wastegate actuators are made from high quality materials which can withstand high stresses and temperatures for prolonged periods of time. They feature fluoro silicone diaphragms with nomex reinforcement to withstand high working pressures and high temperature.
Turbosmart internal wastegate actuators are highly adjustable, with a wide variety of springs between 3 – 26 PSI available, and also feature a collar locking system which allows for fast and reliable spring changes.
The most common reason for investing in an external wastegate is fitting an after-market turbo or better control of the boost and consequently the power output of your engine. Additionally, most large frame turbochargers are not equipped with internal wastegate systems. Most tuners will recommend an external wastegate for any engine producing 400hp or more, as running high boost through a factory internal wastegate can overpower the actuator spring, limiting maximum boost level. Aftermarket external wastegates feature bigger inlet and outlet ports, higher pressure springs and bigger actuator diaphragms to effectively control high boost pressure. Turbosmart wastegates offer superior flow path and high temperature resistance. They are designed and manufactured using the latest technologies. Turbosmart wastegates are market leaders in their sectors, outperforming and outlasting the competition.
The all-new addition to the Turbosmart line-up is the fresh air ALV40 (Anti-Lag Valve) for motorsport applications. Featuring a 40mm valve diameter and a purpose designed actuator housing. Multiple fittings are also supplied for ease of fitment and fabrication.
The fresh air valve allows for incoming charged fresh air from the turbo to be diverted safely into the exhaust manifold pre-turbine wheel with the throttle at low opening angles to allow for safer spooling of the turbocharger without the potentially damaging throttle based late combustion event style anti-lag that can induce high engine stresses and break connecting rods.
The ALV is a sealed twin chamber design with the top port being the primary control port, the spring is designed to open under vacuum conditions to allow for the air to bypass into the exhaust manifold, the lower chamber for twin port control methods, to control the valve irrespective of manifold pressure and shaft seal allows for leak proof operation.
There are two types of boost controllers; mechanical and electronic. Mechanical (or manual) boost controllers offer up to two boost settings set by the driver and controlled via a switch. They are easy to fit, simple in operation and require little maintenance. Electronic boost controllers are a far more sophisticated solution offering a host of boost settings mapped against different triggers like gear change, time, rpm or a manual switch.
The Turbosmart Manual Boost Control Valve range is one of the best dollar for horsepower upgrades that you can make to your turbocharged petrol or diesel engine vehicle. Turbosmart Gated Boost Controllers offer up to two boost settings set by the driver and controlled via a switch. They are easy to fit, simple in operation and require little maintenance resulting in a great dollar for horsepower solution! The range features our exclusive Gate feature which improves turbo response by up to 800 rpm earlier in the rev range – this means that you can increase the performance and response from your engine without even raising the maximum boost level.
Thanks to the Turbosmart Detent Adjustment System, stable and accurate increases in boost over wastegate spring pressure (200%+ for internal wastegate and 100% for external wastegates) are easily and predictably achievable. Manufactured from high-grade brass and billet aluminium and assembled with the famous Turbosmart attention to detail, these boost controllers are renowned for their easy installation, robust design, stability reliability.The Turbosmart Gated Boost Control Valve range is ideal for mildly modified turbocharged engines and perfect for increasing boost levels on factory turbo cars and turbocharged engines.
The Turbosmart e-Boost range of boost management systems are one of the most popular, powerful, and user friendly ranges of electronic boost controllers on the market. Turbosmart e-Boost controllers give you the ultimate control over the boost curve with smart features designed for one thing – performance.
All Turbosmart e-Boost controllers feature our exclusive adjustable gate pressure feature which improves turbo response by up to 1000 rpm earlier in the rev range. This means that you can increase the performance and response from your engine without even raising the maximum boost level. e-Boost controllers also allow the user to control 3 different aspects of the boost curve; the maximium boost pressure (set point), the spool up rate of the turbocharger (gate pressure) and the reaction time of the controller (sensitivity).
Each unit is housed in an aluminium case for durability and strength, while a simple 3 segment display is used for easy viewing and navigation in all extreme driving conditions.
Mechanical boost gauges and electric boost, EGT and transmission temperature gauges. Featuring a black face with silver bezel and bright backlighting, these gauges are the perfect accompaniment to any interior.
Most late model cars have in-built defence mechanisms to guard against increases in boost pressure. Such systems are important, but can be an obstacle when increasing boost pressure and the performance of your turbocharged engine. Turbosmart FCDs provide a reliable and accurate increase in the factory fuel cut-out level. A Turbosmart FCD will allow boost pressure to be increased above the factory level and prevent momentary shutdown of the fuel injectors - hence maximising the factory turbo system.
The installation of performance fuel injectors or a high-flow fuel pump requires the use of an aftermarket fuel pressure regulator to allow pressure adjustments while maintaining a stable base pressure. They can also be used to maximise a standard fuel system’s ability to cope with minor power modifications.
All Turbosmart FPRs are manufactured from billet aluminium and hand-assembled to ensure maximum precision. Turbosmart FPRs have been designed to provide smooth and stable fuel pressure delivery under all conditions from idle to full throttle and are suitable for use with both electric and mechanical fuel pumps. Turbosmart FPRs feature an easy screw and lock adjustment and provide a stable 1:1 ratio between fuel pressure and manifold pressure.

Oil management is an important part of ensuring the longer life of a turbo. Turbosmart offers a solution to control the oil pressure going to the turbocharger, ensuring it never exceeds the maximum oil pressure turbocharger manufacturers specify. The result is an oil delivery system that is more reliable and easier to setup than a standard restrictor system.
Turbosmart’s new patent pending OPR T40 is an oil pressure regulation system for your ball bearing turbocharger. It helps prevent compressor or turbine stage oil leaking or smoking, and takes the guesswork out of oil restrictor sizing for more efficient and effective oil delivery. Providing an aftermarket turbocharger with the ideal oil pressure has always been a challenge. Traditionally, the turbocharger’s oil feed has relied on a restrictor system, which are difficult to set up correctly. When incorrectly sized or set up, they can be the cause of turbo seal leakage and blow-by. Turbosmart’s Turbo Oil Regulator ensures the oil pressure going to the turbocharger never exceeds the maximum pressure turbocharger manufacturers specify for oil supply, regardless of engine oil pressure. The result is an oil delivery system that is more reliable and easier to setup than a standard restrictor system.
Turbosmart’s turbo oil feed filters make sure your turbo is always fed with clean oil. Due to their small oil galleries, it’s highly important for the turbocharger to be spared of any debris that may become dislodged from the engine, and a 44-micron stainless steel filter element ensures even the smallest particles are kept away from the turbo. The oil feed filters are available with both -3AN and -4AN fitting sizes.
Turbosmart’s billet turbo oil feed flange adapters offer a reliable and simple solution to prevent oil leaks at the turbo oil drain, improving safety. Turbosmart’s hard anodized billet turbo oil drain flange adapters offer a reliable plug-and-play solution to fit Turbosmart’s Oil Drain oil drain to a -8AN or -10AN fitting. Three sizes of flange adapters are available to suit a wide variety of turbochargers.
Turbo oil leaks are not only annoying, but they can also be a common cause of engine fires in motorsport. The problem can often be traced to an incorrectly setup turbo oil drain. Turbosmart’s billet turbo oil drains offer a reliable and simple solution to prevent oil leaks at the turbo oil drain, improving safety. They get the drain further away from the turbine housing, allowing better access to fittings and improved heat management.The Oil Drains, available in -8 or-10 AN thread sizes, offer reliable sealing under high pressures thanks to their ORB (O-ring boss) sealing fittings.
