Why would I upgrade my factory Diverter or Bypass Valve?

Fundamentally, factory Diverter Valves are built to a price point rather than with performance in mind. At Turbosmart, we want you to have the best performance available. Our upgraded valves are designed to overcome the limitations of factory equipment with improved sealing and valve dynamics. A Turbosmart Upgraded Valve will ensure you have all your available boost with a maximum response.

How does the Turbosmart Valve provide performance benefits?

The Turbsmart Range of Direct Replacement Valves uses our Unique Boost-Balance Valve Technology, a Positive Seal O-Ring on the Piston Face, made from Motorsport Proven and assembled Billet Aluminum. These features ensure the fastest responding valve and incredible boost-holding characteristics in a virtually indestructible valve.

What is the Turbosmart Boost-Balance System?

Our Valves are designed to ‘actuate or open’ via a pressure differential rather than boost alone. This means we can run the lightest possible spring for a super-fast response, but it also means both sides of the piston are subjected to the same boost pressure when accelerating and under load. This means no matter how much boost you run, Turbosmart Valves will not open unless you want them to! You have all your boost pushing it closed at any point in time, PLUS the spring itself!

What is the Turbosmart Positive Seal O-Ring, and why does it matter?

As mentioned above, due to our Boost-Balance technology, the piston of Turbosmart valves is constantly being pushed into the valve seat when accelerating and under load. On Turbosmart valves, unlike others, we use a Viton O-Ring on the face of the valve, which ensures the best possible seal against the body. This seal means maximum boost pressure at all times and improves boost response.

Can I Vacuum or Smoke test my Kompact Valve?

These do not use an O-ring on the side of the piston and are not based on a diaphragm like the OE equipment; the design focus is on sealing, speed and overall flow. You can vacuum test these valves. However, you will need a hi-flowing mechanical vacuum pump – you cannot use a hand-actuated vacuum pump as these do not replicate the flow your valve would see when fitted to an engine, meaning you will likely achieve nothing except for a ‘False-Positive’ to a leak test. This design and lack of diaphragm or O-Ring suggest you cannot use a smoke test to test or validate a Turbosmart Valve.

How much Horsepower will these valves handle?

More than you have! Due to the unique Turbosmart Boost-Balance System, you can’t have too much power or boost for the Kompact Range of Vales and at no point will they leak based on ‘Too-Much’ anything. The more boost you run, the better they will seal. With that said, highly modified engines may be able to find the limit of how much these valves can bypass when open, and this is the only limit. If you’re at this level, you may consider a remote-mounted valve with more flow potential to avoid audible compressor surge. However, the valve will not open or vent due to too much boost or power.
