Our friends at RallysportDirect.com wanted to upgrade the factory diverter valve on their “White Sheep” project Ford Focus ST. Turbosmart BorgWarner Kompact Dual Port was the obvious choice. The installation was pretty straight forward and the product was given two thumbs up review.
“This video shows you our White Sheep Focus ST before and after the Turbosmart Kompact Dual Port BOV install. With the stock BPV being a known weak point on the Ecoboost motors it makes sense to replace it before you have a problem.”
At Turbosmart we aim to make our products tough, reliable but also user-friendly. Our market research notes all your feedback and suggestions and they become a part of our new product design brief.
We all know the atmospheric valves have a bigger flow capacity and are louder than the bypass (diverter) valves. But what if we want to have both of those features on a single valve? The new Kompact VAG Dual Port provides just that. It offers a combination of bypass and atmospheric venting in one product. But that’s not all. With the Kompact VAG Dual Port you can control the ratio of bypass to atmospheric venting via a unique rotating collar.
ABOVE: The rotating collar, located just above the mounting plate, controls the flow direction of excess boost pressure.
ABOVE: The collar in the Open position (left) vents both to the atmosphere and back into the intake. As the collar is turned to the Closed position (right) more flow is diverted back into the intake.
The operation of the adjustable collar on the Kompact VAG Dual Port could not be simpler.
Turn the collar clockwise to open the vent-to-atmosphere port and enjoy a high-flowing, great sounding valve.
Turn it anti-clockwise to close the atmospheric port and vent the excess boost pressure back into the intake for a quiet operation – ideal for the day to day driving duties. It really is that easy!

The popular Kompact Plumb Back and Dual Port valves are now available for the cars using Ford Ecoboost engine.
Turbosmart BW/KKK/Ecoboost Kompact Series valves have been specifically designed to suit BorgWarner EFR and KKK turbos. They also fit the popular Ford Ecoboost applications.
Unlike the standard, plastic valves that use un-reinforced diaphragms and are known to crack under increased boost, the new BW/KKK/Ecoboost Kompact valves use O-Ring sealed piston which, coupled with their billet aluminium construction give them over 30PSI boost handling capability.
The BorgWarner/KKK/Ecoboost Kompact valves are available in Plumb Back (recirculating) and Dual Port (recirculating/atmospheric) models.

APPLICATION: • Porsche 911 Turbo (997) and 911 GT2 (997)
• Volvo S40 T5, S60 T5, C30 T5, C70 T5.
• Chevy Cobalt SS 08-10
• Ford Focus ST and F150.
Turbosmart’s Kompact Plumb Back is now available for the Nissan Juke.
Installation is quite straight forward. The first thing to do is to unsnap the plastic engine cover and set it to the side. A gentle tug is all that is needed to remove it (no bolts or fasteners holding it down).
This exposes the factory plastic diverter valve on the top of the motor:
Using pliers compress and slide back the factory clamps. Next carefully pull the hoses off.
Now, using a 10mm socket with an extension and swivel, remove the two mounting bolts and remove the factory diverter valve.
Installation is the opposite of removal. Take your Turbosmart billet bypass valve and install using the supplied gasket.
Turbosmart might be famous for fitting a lot of performance into small packages but that doesn’t mean we don’t appreciate the fact that sometimes bigger is, indeed, better. This is exactly the premise behind the Big Bubba range.
Big Bubba is, as its name suggests, big, bold and in-your-face. It is by far the largest valve in the Turbosmart range. But it’s not all about the size and looks – Big Bubba packs a lot of punch too! With a heavy duty, CNC billet aluminium body and components and a 52mm (2.05”) hard anodised aluminium two-piece piston, Big Bubba gives a new meaning to the term “hardcore”.
A -4AN threaded vacuum port offers a wide variety of connection methods. Outlet fitting size: 50mm (2.0”). To make things easy we’ve ensured all Big Bubba valves use the same inlet flange and V-Band clamp as the Turbosmart Race Port.
All that in a package that weighs only 790 grams (1.7lbs)!
In this range:
Big Bubba – a recirculating (bypass/diverter) valve, Bubba Sonic – a vent-to-atmosphere valve. Both Big Bubba and Bubba Sonic are available in three colour options: Blue, Black and Sleeper.
Big Bubba has been designed for big horsepower, high performance and high boost turbo and supercharger applications. If you’re looking for an inconspicuous, valve for your small capacity, low boost daily driver you will need to look elsewhere!
All the owners of big and small block Chevs and Fords, drag rotaries, straight sixes and big turbo diesels looking for a better response from your turbo or supercharger – the Big Bubba range is for you!
In their “Better Boost Solutions” section, the staff of Muscle Mustangs and Fast Fords magazine have installed a Helion Turbo System on their project 5.0L Coyote.

Using Turbosmart Ultra-Gate38s, Supersonic BOV and a Boost Tee, the crew managed to get 811hp and 715lb-ft of torque at just over 7psi. They went on to extract 907hp with 802lb-ft of torque with the boost turned up to 10psi.
When we handed the Moto IQ writer Wes Dumalski one of our Internal Wastegates and a Plumb Back valve for a review we knew they would come under some serious scrutiny.
Wes fitted the IWG and the Subaru Plumb back to his Gen 3 STi and after a slight hiccup the products performed flawlessly. In fact Wes seemed quite impressed:
“As you would expect from Turbosmart their stuff is first rate, no corners are cut from design to packaging!” “The STi does not suffer from a lack of low end power however when you add the IWG 75 it wakes the eff up!”
